I would upgrade to M3 and above. Shooting Menu 1 (Page 2, Quality/Image Size2) Long Exposure NR: On. The settings available in the Fn menu are as follows: Drive Mode: The A7III lacks a dedicated Drive Mode Dial (Like on the A9), which means that you need to change drive mode via the Fn menu or to assign this function to one of the custom buttons. I hope you found these latest tests of interest. It is possible to power the camera though the USB port (indeed that’s how you charge the battery, as no separate battery charger is supplied as standard, a deficiency). One more important setting that affects power usage is the Remote Control menu setting. I set my white balance to 3900ºK for astro-landscape photographs, because I have found it consistently produces a sky color pleasing to my eye. But it can take the Canon lenses you might already own. 3. Hi Alan, Just wondering if you have done a test of the dark frame noise from the a7iii, or for any of your camera reviews. The monitor will more closely resemble what the camera will record, the monitor will consume less power, and the glow from the LCD is less distracting to those photographing near you. The lower weight can be helpful for use on lightweight telescopes, on small motion control devices, and for simply keeping weight and bulk down when traveling. This is the approach I have taken, and it is one feature of the Sony A7Rii that simplifies and speeds up camera usage considerably. Turning this ON superimposes a shimmering effect on parts of an image judged in focus. In Continuous mode, I think the effect is still there but maybe a little less. Plus there are an increasing number of lenses from third parties offered with native Sony E-mounts. So if I am shooting RAW files, why do I care which Creative Style is set? Which will have the lower noise? Only set the Remote Control to On for the duration you intend to use the IR Remote, and turn it back Off afterward. I just read your evaluation of the Sony A7III in Sky & Telescope. Aperture priority mode, selecting aperture based on desired depth of field. Setting Effects Off” appears to perform the same function as Bright Monitoring, with a couple of twists. With default settings, the LCD monitor remains powered on for the duration of the exposure(s). The quick fix is to just set the USB Connection type to PC Remote, and the problem seems to disappear. Long Exposure Noise Reduction :: Camera Icon 1 – 2/14. Change ), You are commenting using your Twitter account. The Sony would perform better in an ISO Invariancy “face-off” if its ISOs were kept above 640, to keep all the images within the Sony’s upper ISO range of its dual-gain sensor design, with two ranges (100 to 400, and 640 on up). Bright Monitoring does not appear in any of the in-camera menus you can scroll through, so you won’t stumble across it. Back button focus reassigns the auto focusing initiation to a button or function key on the rear of the camera body, instead of the usual half-press of the shutter. I find the Function Menu to be a good location to place functions I use frequently in daytime photography, while reserving the Custom Key assignments for those functions I use most often at night. This results in tremendous energy savings during these types of exposures. Stars 1 or 2 pixels wide are a little too colorful! It is a step in the right direction, but not an optimal solution regarding ease of use. For use on telescopes, the simple adapters will be sufficient, and necessary as many telescope-to-camera adapters and field flatteners are optimized for the longer lens flange-to-sensor distance of a DSLR. My children and grandchildren are the reason, but it's the passion that drives … My primary use for focus peaking is with focus stacking situations, to visualize which zone is in focus at the moment. Battery Life Having some investment in the Sony ecosystem (Nex 5N + various lenses), It’s an area I’d hope Sony address, and would remove an upgrade barrier for me that’s almost as significant as the start eater issue. Zebra Patterns help the photographer see where the clipping occurs in an image, and to make appropriate adjustments if necessary. All three are “entry-level” full-frame cameras, with 24 to 26 megapixels and in a similar price league of $1,500 (Nikon) to 2,000 (Sony). First, the automated eyepiece sensor switching is disabled during LCD use, so that the photographer makes the choice of which display to use. (See my test at https://amazingsky.net/2017/08/09/testing-the-canon-6d-mark-ii-for-nightscapes/). https://blog.kasson.com/a7riii/the-sony-a7riii-eats-stars/ Nevertheless, noise performance of the Sony a7III was still excellent, with both the Sony and Nikon handily outperforming the Canon 6D MkII, with its slightly smaller pixels, by about a stop in noise levels. Yes, this can all be done later in processing, but having the camera do the stacking can often be convenient, and great for beginners, as long as they understand what those functions do, or even that they exist! Auto 100-8000 ISO range. 4. And, as I found, the Sony might need to be placed into Continuous shooting mode to have the shutter fire with every trigger pulse from the motion controller. However, I emphasize that the noise increase from using LENR with the Sony was visible only when severely boosting underexposed images in processing. My Custom Key Settings For Night Photography. The D750 is fabulous but the Sony is almost as good – much better for Live View – and accepts all lenses. At 24 fps videos are full-frame with no cropping. This is really pixel peeping at 400%. The 50mm focal length is made even greater when you pair it with a crop sensor camera where it can become something like a 75mm lens. The cause is not clear. No difference. It’s just a pity the 6D MkII has only a 3-frame buffer when using LENR. It was a little worse than the stock Canon 6D MkII. These beginner-friendly camera settings and tips should help you get your first successful image of the night sky. The factory default setting is Standard, but I have switched to Neutral instead, and here is why. I just want to address, in amateur fashion, the very basic aspect: incoming photons collected by a pixel. This might be useful for long shoots, though likely as not that same USB port will be needed for an intervalometer or motion control device. However, if the collection area is large, the incident “stream”/pixel is larger = less affected by variations. Lower LCD brightness might also help retain night vision, but I have not seen evidence of this from any other sources, so just call it a hunch of mine. First of all congratulate you, a very good publication. Mirrorless systems are shrinking the size of the camera body, and with that comes smaller batteries with less capacity than their DSLR siblings. I have used Sony cameras for astrophotography for years and have never noticed a star eater problem. This is a very excellent and demanding review with a lot of effort on your part using 3 cameras at one time “BRAVO”. What a thorough piece of work. Apparently, the multi-functional USB port provided on the Sony A7Rii can sometimes get confused when in Auto mode. SAIFFER Settings Set up your camera with the following settings: Shutter Speed: Use1/60 sec or faster […] How evenly an image is illuminated is a common factor when testing lenses. Here are some other Sony a7III features I found of value for astrophotography, and for operating the camera at night. Try it. The Custom Key Settings are subdivided into Page 1 and Page 2. This is most noticeable – indeed usually only noticeable – when shooting deep-sky targets though telescopes. Take a picture! Jeff — Thanks for your comments and interest. But that’s a nuisance to do, and should not be necessary with a mirrorless camera. While the camera is in use, the default settings result in the LCD being on. I put this on C1. Time-Lapse Smoothing  I did not see any significant “star eating” in any long exposures even up to the 4 minutes I used for some deep-sky shots. When using its internal intervalometer, the Nikon D750 has an excellent Exposure Smoothing option. The menu structure used in the Sony A7Rii consists of six top-level menu tabs, with each tab containing numerous sub-pages. There are various Creative Style presets available on the Sony A7Rii including Standard, Vivid, Neutral, Portrait, Landscape, B&W, Clear, Deep, Light, Night, Autumn, Sepia and Sunset. And both cameras performed much better than the ISO “variant” Canon in this test. And what else could you compare it to? A great app I found with the A7S and A7RM2 was Digital Filter which is good for city lights below and dark sky above, you can capture two images in camera with different settings for the above and below and get a RAW combined in camera image to use in post instead of Photoshop blending, again just for thought. The Sony a7iii is one of the best cameras for nighttime photography, which if you know me is mostly what I do. Jim Kasson’s testing (https://www.dpreview.com/forums/post/61074932) provides strongly conclusive evidence that it is still present, and your first comparison shot with the Canon 6d shows small stars in the Sony that are characteristically ragged and with a dominance of green colour – exactly the features explained in Mark Shelley’s reverse engineering of Sony’s latest spatial filtering algorithm. If you wish to argue the point, do so with evidence. (True 4K is actually 4096 x 2160 pixels.). Great article. Thanks Steve! In-Camera Image Stacking  This is all with Raws developed with Adobe Camera Raw. In this test, the Nikon did not perform as well as the Sony for ISO invariancy. Cheers! This is much more apparent when comparing files of those ISO levels from dpreviews studio tests between the bodies. Is it? It’s also great for video. I mostly keep mine set to “Single Shooting” and change to “Continious Shooting” when I shoot action or I photograph handheld in low light to … The cameras were on a Star Adventurer Mini tracker to keep stars pinpoints, though the ground blurred in the longer exposures. The one thing that I would like is the on camera apps that can be put on the M2 and below. NIKON: I deducted points for real-time video of auroras – the D750 can do them but is pretty noisy with the high ISOs needed. It offers 4K (or more precisely UltraHD) video recording for videos of 3840 x 2160 pixels. I have the A7S, A7RM2 and A7M3 and have been playing with the A7S since 2014, 2016 A7RM2 and 2018 A7M3 with Astro MW and other things. To me, the star eater effect on the Sony a7III is a non-issue. On the one hand, the problem of compression artifacts has been eliminated, but at the cost of greatly increased file size: The advantage of using the new, 14-bit uncompressed RAW format is tempered by the doubling of the RAW file size, which not only increases storage space requirements, but also the computational power required of the editing equipment in use, especially when considering that many astro-landscape techniques involve the layering of a large number of images within editing software. I tell you this, since the price of the sony a7iii is much higher than that of the 6d mark ii, do you think the sony a7iii, would you continue to earn the 5d mark iv canon astrophotography? The correct exposure for the scene was 30 seconds at ISO 6400 and f/2. Nor the Sony, as it has no intervalometer at all. Because the camera applies the Creative Style to the LCD and EVF displays. They will be the same, because it is the pixel size not the sensor area that matters. In most shooting situations, I found using LENR provided the overriding positive benefit of reducing hot pixels. However, like other brands’ internal intervalometers Sony’s is good only for exposures up to 30 seconds long. I have not had a chance to experiment fully with the ability to use the Live View Display while out in the field, so I can’t say which is ultimately better to use, or what the trade offs might be, but when I know more, I will update this post. Image quality was just fine. However, I’ve found these post-shoot darks rarely work well, as the dark frames are not at the same temperature as the light frames, and often add noise or dark holes. My color-managed workflow philosophy is simple – (1) capture as much useful data as possible in the field, at the highest resolution, greatest bit-depth and broadest color space offered by my equipment; (2) maintain the quality of this image data throughout the editing and printing process; (3) make my own decisions regarding image quality, color temperature, sharpness, etc. Now I know why I haven’t seen you on my email feed in awhile! But this test re-emphasized my thoughts that Canon DSLRs remain the best for long-exposure deep-sky imaging where you can give images as much exposure time as they need, while the ISO invariant Sony and Nikons exceed at nightscape shooting where exposures are often limited and plagued by dark shadows and noise. This makes it so easy to frame nightscapes and deep-sky fields. The dark frame kicks in and locks up the camera only after the series of “light frames” are taken. Much of what I have learned has come from paying attention to lessons others have generously shared along the way. OK, let’s try that. Overall Recommendations they turn off during exposures), lit buttons would be very handy at night. For still photos, the Sony a7 III has an ISO range from 50 through 204800. Great article, I have to note one thing though. I show only the Sony and Nikon compared here, shot at the common range of ISOs used for nightscape shooting, 800 to 12800. Compressed files showed more noise and magenta discoloration in the shadows. Features  In order to see the real situation with the noise you need to compare pictures with a large lack of lighting. The higher noise of the Canon is visually obvious, but I’d say the Sony a7III and Nikon D750 are pretty equal visually for noise, despite the numbers. It turns out the two-stage compression scheme used by Sony has a nasty side effect – problems with haloing and artifacts along high-contrast edges. Spencer’s Cameras who do mods says the same. I trust you’ll find the review of value. Well pro’s use tools and programs (apps) on a camera that get the end result they want/need without hauling valuable gear to a site to capture. To reduce battery drain it is possible to turn off the EVF completely – I find I never use it at night – and to turn off the LCD display when shooting, though the latter is an option you have to activate to add to the Display button’s various modes. Finally we have the ISO setting. Not so great for night sky photography. In describing my selections, I will use the form [2-5] for instance, which designates Tab 2 (Custom Settings) – Page 5. However, while the Sony has a Bulb setting there is no Bulb Timer as there is with the Canon. Thanks for the suggestion. I love to shoot the night sky, especially with a wedding couple. closely match what existed in the scene, since the previews are also jpeg representations of the RAW data, as modified by the white balance set in camera. I currently have an a7RII but have been considering the a7III, in part because I had read some things that seemed to indicate that it had better low light noise properties. However, the Sony A7R III handles noise well and even images at ISO 25,600 impress. Here I compare all three cameras for this effect in two-minute tracked exposures taken with Long Exposure Noise Reduction (i.e. If stars are colored and misshapen at the single pixel level that’s deBayering.  This button is perfectly situated to press for auto focus, either while the camera is hand-held or when it is perched on a tripod. Happy shooting, John. On my Sony cameras, I assign a button located on the top right on the back of the camera to control auto-focus, thus taking it off its default shutter-button setting. Both the Sony and Nikon use sensor and signal path designs that are “ISO invariant.” As a result, images shot underexposed at slower ISOs, then boosted in exposure later in processing look identical to properly exposed high-ISO images. But a monster night shooter would be the A7SM3 if left at the larger pixels of 12mm not looking forward to Video stuff (people need to get a video camera look at all the attachments anyway leave the photo cameras alone)…. I have discovered through trial and error that keeping the default USB Connection setting on Auto can lead to intermittent misoperation of several popular brands of intervalometers. The top-level tabs are: Under each top-level tab are up to 9 sub-pages of menu choices. Plus, the Sony was far better than the Canon 6D MkII’s “ISO variant” sensor. The a7 III is Sony’s new entry-level full-frame mirrorless camera. I think it’s a great camera for both astrophoto stills and video. The Canon 5D series also has this. And, of course, the 1.8 aperture. That’s worth a check, too. This is good news, as astrophotography requires fast, high-quality lenses, and the Sony allows more choices. You obviously put some time into your tests. I have finally been convinced to turn this … Here are my Custom Key assignments, with explanatory remarks. After reading about it myself, I tested what i’d read, and saw it to be true. This isn’t a huge detriment, as anyone who really wants to go after deep nebulosity must use a “filter-modified” camera anyway. The Sony test report is revised to explain this. But the Sony, being four years newer than the Nikon, is not better. Hi Alan, I don’t want to detract from an otherwise fantastic review, so feel free not to post this. If you want to save parameters from the Custom Settings Tab or the Setup Tab however, you are out of luck. The Custom Key assignments and Menu Settings I recommend will result in the following LCD/EVF behavior. Cheers! The four C buttons can be programmed for oft-used functions, making them easy to access at night. You will see more detail with smaller pixels but not more noise unless you are cropping photos from these different sensors to the same number of pixels. With LENR on you don’t have to do anything like taking separate shots with the lens cap on. One of the most talked about settings on a camera is the ISO; a numerical value on your camera that controls light sensitivity. is this the opposite effect as stacking, which adds “other frsmes” with unwanted noise?). That’s why we do science! SteadyShot (Sony’s term for image stabilization) is designed for hand-held camera use, and may actually introduce image softness when active while shooting from a tripod. The histogram shows whether highlight clipping is occurring somewhere in the image, but highlight clipping is expected and desirable in some instances, such as in street lamps. The small tree at the top of the image looked very different with the two cameras.  I generally leave it unassigned, but use it occasionally when I would like to temporarily assign functions to a button for aiding in special projects or techniques. Another power drainage issue with the Sony A7Rii results from the default behavior of the LCD/EVF during camera usage. “1 stop better in low light” isn’t always a flat comparison of 200 being as clean as 100, 3200 being as clean as 1600 etc. So my first assignment … Live View Focusing and Framing And for long exposures, my 5DMkII does not offer multiple exposure feature, however, how can i take advantage of 5-frame buffer? The Sony 85mm f1.4 GM lens has a very useful toggle to change between AF and MF quickly . Thanks again for the detailed review. I know … people shoot dark frames separately for subtracting later in processing. You have ignited my fuse, thank you for that. Unless you actually read the full-length 642-page PDF manual (you have to download it), you won’t know about it. But astrophotography, which often requires extreme contrast boosts, reveals non-uniform illumination of the sensor itself, regardless of the optics, originating from hardware elements in front of the sensor casting shadows onto the sensor. I found the a7III would use up about about 40% of the battery capacity in a typical 400-frame time-lapse on mild spring nights, with 30-second exposures. You can take full advantage of wide-angle lenses, great for auroras. To alleviate random (high ISO) noise from an image, many photographers have adopted a method of stacking up to a dozen sequential exposures, for the purpose of averaging out random, high ISO noise. You can send one or several images directly to your wireless device (phone or tablet) by pressing this button. Sony provides four methods to help overcome this problem: Of the four methods listed above, the one most effective in simplifying use of the Sony A7Rii is item 4, Custom Key assignments. Use the ISO that will produce a well exposed histogram for the shutter speed and aperture dictated by the scene. Take a full-frame camera and shoot a low-light, high-ISO image with it set to full-frame mode vs with it sent to take a cropped APS frame image. I rarely set LENR to On. None have been tempting until the a7III came out. The Canon is free of any such issue – stars are naturally colored whether LENR dark frames are applied or not. Simply pressing [C2] instantly toggles between auto and manual focus. Thanks! I think any really ‘serious’ astrophotography users would be looking at a dedicated astro camera (CCD or CMOS), but know you can get some amazing results with a ‘normal’ quality camera such as those compared in this review. What iso would you recommend for the a7iii if you could pick any iso (so not limited by individual situations)? Effectiveness of Long Exposure Noise Reduction (LENR), Quality of Raw files, such as sharpness of stars, Brightness of Live View for framing and focusing. of a find!! A nice in depth article that answers many questions for me. With Sea & Sea's quality construction this high-end, aluminum housing offers full camera control, features molded grips, glow-in-the-dark buttons, and nice ergonomics for easy control. Unfortunately, I think that you’re conclusions re star-eater are based more on hope than reality. Thanks for the suggestion. Canon and Nikon both offered factory modified cameras at one time, notably the Canon 60Da and Nikon D810a. The effects of the algorithm are clearly visible in your test images when comparing 3.2 and 4 s exposures. So you still need an external intervalometer for time-lapses with frames over 30s long. Stars are not smoothed out in long exposures. OK, we’re almost done! If you have ever looked at the apps on Playmemories site (a selling point when I bought the A7S back in 2014 [no other camera offered and is ground breaking]). Those underexposed images were then boosted later in processing (in Adobe Camera Raw) by the required Exposure Value to equalize the image brightness.
