CANON: The 6D MkII’s lack of an ISO invariant sensor rears its ugly head in underexposed shadows in dark-sky nightscapes. Going to be very hard to get good astro at f4. Here are 7 astrophotography tips that have helped me capture hundreds of images of the night sky including stars, the Milky Way, Galaxies, Nebulae and more. SONY TILTING SCREEN It tilts up and down but does not flip out as with the Canon 6D MkII’s. Video Capability  STAR TRAILS and AURORA With the Laowa 15mm lens and Sony A7III, for 155 exposures, all 20 seconds at f/2.8 and at ISO 800, and taken as part of a 360-frame time-lapse. Turn on LENR and it is possible to shoot three (with the 6D MkII) or four (with the 6D) Raw images in quick succession even with LENR turned on. This isn’t a huge detriment, as anyone who really wants to go after deep nebulosity must use a “filter-modified” camera anyway. Indeed, at slower ISOs and longer exposures, more stars are visible. Or rendered with little or no color at all. (See other lenses that work.) Here I compare all three cameras for this effect in two-minute tracked exposures taken with Long Exposure Noise Reduction (i.e. Assign it to one of the hardware Custom C buttons. the 500 rule is pretty bad for today's cameras. 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. In conclusion, here’s my summary recommendations for the three competitive cameras, rating them from Poor, to Fair, to Good, to Excellent, SONY: I deducted marks from the Sony A7III for deep-sky imaging for its lack of a light frame buffer, poor red sensitivity, odd LENR performance, and amp glow not seen on the other cameras and that dark frames did not eliminate.Â. How tough would it be to add it, Sony? Alan Dyer is an astrophotographer and author of astronomy books based in Canada. Stars are visible to the same limiting magnitude and close double stars are just as well resolved across all exposures. This lens balances nicely when paired with the Sony A7III and has a sturdy feel. I expected the new BSI-equipped Sony to better the Nikon by about a stop. This is a blow-up of the lower corner of the frame, as indicated. Camera Settings for Astrophotography There are certain rules that you must abide for capturing the space and the Milky way. Between 3.2s and 4s a very slight one-pixel-level softening does kick in, reducing noise and very slightly blurring stars. I tested a Sony A7III purchased locally. For the price, the Sony a7III is one of the best values on the market. It intrudes into the light path ever so slightly. He fell in love with photography in 2013 when he got a camera as a birthday present. Canon and Nikon both offered factory modified cameras at one time, notably the Canon 60Da and Nikon D810a. But it is compatible with many external intervalometers and controllers. I trust you’ll find the review of value. I have now retired my Sony a6000 and added a new filly to the stables, a Sony a7III. Otherwise, I agree with /u/RathEmpire's settings, I think you can probably go to 3200 or 6400iso if this is too dark. Still, this is a neck- and back-saving feature for astrophotography. Also, when boosting the exposure a lot in processing, the images taken with LENR on showed more shot and read noise than non-LENR frames. Press question mark to learn the rest of the keyboard shortcuts, As soon as the Sony a7S was announced, I knew I had to try it for astrophotography. Try it. The Sony doesn’t do quite as well as the Canon 6D MkII. The 500/focal length rule for exposition time is also usually working to avoid star trails, but it can wield different results depending on how far from the Polar star you are actually aiming. Whether you are pursuing DSLR telescope astrophotography or simple using an astrophotography tripod , there are certain tricks and techniques you must follow. The camera itself can be used in a number of different settings such as dusk and dawn, and … It just needs to be better, Sony! As its name implies, a mirrorless camera lacks the reflex mirror of a digital single lens reflex camera that, in a DSLR, provides the light path for framing the scene though the optical viewfinder. In most shooting situations, I found using LENR provided the overriding positive benefit of reducing hot pixels. These were then boosted in Adobe Camera Raw by 2 and 4 stops in Exposure Value (EV) to compensate. Your cameras are getting worse for astrophotography while Sony’s are getting better.Â. Quick Answer: The 5 Best Rated Lenses For Sony a7iii For 2021 Sony SEL50F14Z Planar T* FE 50mm f/1.4 ZA Lens Sony advises that when using LENR Raw images are recorded with only 12-bit depth, not 14-bit. With its good shadow details, you have to apply less shadow recovery in post-processing, which does keep noise down. Keep in mind, these are vastly underexposed images. A lot of people buy a nice camera and then use it with all the default Live View was absolutely superb, though the outstanding Bright Monitoring function is as well-hidden as Sony could possibly make it.Â. I like its image stacking options, which can help alleviate the noise and artifacts in still images, but aren’t practical for time-lapses. Which means higher iso. COMPACT CAMERA and LENS – The Sony A7III with the compact but fast Laowa Venus Optics 15mm f/2 lens. I use a $50 Vello unit, and it works very well. The lowest cost units just adapt the lens mechanically; the more costly units also transfer lens data and allow auto focusing with varying degrees of compatibility.Â. We shoot everything on manual. 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).Â. While there are many different ways to set up a Sony, these are my top three custom settings … SONY WITH THE SYRP GENIE MINI – The Sony A7III worked well with the Syrp Genie Mini motion controller with the right shutter cable but only when placed in Continuous mode. It shouldn’t. The Sony showed some slight edge-of-frame shadowing from the mask in front of the sensor, as well as a weak purple amp glow. Sony A7iii - Essential Settings for a DSLR convert! Filed Under: Reviews Tagged With: A7III, Alan Dyer, Astrophotography, sony, Sony A7III, star eater. I want to switch to Sony A7 III. I've tried a few at 14mm, f2.8, 20sec aa 25600iso and I got amazing pictures from it. It’s unfair to blame just the hardware or the software. There are many people testifying that the Sony a7III is a great choice for beginners due to its versatility and ease of use. CAMERA TRIO – The Sony A7III, Nikon D750, and Canon 6D Mark II. AURORA VIDEO FRAME – This is a frame grab from a real-time 4K video of a “Steve” aurora. ADAPTING TO A TELESCOPE – The MetaBones adapter, as will other brands, adds the correct lens flange to sensor distance for telescope field flatteners to work best. The cameras were on a Star Adventurer Mini tracker to keep stars pinpoints, though the ground blurred in the longer exposures. Samyang 135mm f2.0 ED UMC. NOISE AT ISO 6400 – At ISO 6400, the Canon begins to show excessive noise, about a stop worse than the Nikon and Sony. Over the last year or so, firmware updates from Sony introduced a much-publicized penchant for Sony Alphas to “eat” stars even in Raw files, apparently due to an internal noise reduction or anti-aliasing routine users could not turn off. Most tests focus on its superb auto exposure and auto focus capabilities that rival much more costly cameras, including Sony’s own A7RIII and A9.Â, For astrophotography, none of those auto functions are of any value. 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. As versatile as a mirrorless camera is for lens choice, making use of that versatility requires buying the right lens adapter(s). (See my test at, And its light-frame buffer is great for minimizing shooting time for a series of deep-sky images with in-camera LENR dark frames, which I find are the best for minimizing thermal noise. STAR TRAILS and AURORA With the Laowa 15mm lens and Sony A7III, for 155 exposures, all 20 seconds at f/2.8 and at ISO 800, and taken as part of a 360-frame time-lapse. It may be more serious on other Sony alphas. I know … people shoot dark frames separately for subtracting later in processing. Sony A7 III, A7R III, A9 Metering Settings. As photographers age, this becomes a more essential feature! The Sony still showed some discoloration artifacts and added noise when boosting images by +4 EV that the Nikon did not. Use Compressed only if you plan to take lots of time-lapse frames and need to conserve memory card space on extended shoots. It did not. The Nikon seems to discolor stars only when LENR is applied. SeeÂ, With the Alpine Laboratories Radian2, exposure ramping is not possible with a Sony, only basic shutter triggering. This is good news, as astrophotography requires fast, high-quality lenses, and the Sony allows more choices. Also missing, and present on most new Canons, are Multiple Exposure modes for in-camera stacking of exposures in a Brighten mode (for star trails) or Averaging mode (for noise smoothing).Â. It magnifies the Live View by 5.9x or 11.7x, allowing for precise manual focusing on a star. 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. Maybe a bit noisy (hard to tell as I had a CLS filter), but still interesting to look at ^, 24mm you're gonna wanna keep shutter speed at around 15 seconds to not get visible trails. Nor is there any amp glow anywhere along the frame edges. Again, the Sony records just as many stars as the Nikon. The A7 III is a fairly complex camera with tons of features, so I’m going to share exactly how I set my camera up for maximum efficiency on a portrait shoot. Yet, just as many stars are recorded and are resolved, and at the lower ISOs/longer exposures more stars are visible because faint stars are not lost in the noise. Mode 1 was selected on the Sony lens. I haven’t seen amp glows in cameras (at least in the DSLRs I’ve used) for a number of years, so seeing it in the new Sony A7III was another surprise. This emphasizes just how good the Nikon D750 is.Â, 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.Â, NOTE: I performed all Raw developing with Adobe Camera Raw v10.3. FINDING BRIGHT MONITORING – The excellent Bright Monitoring function is accessible only off the Custom Key menu where it appears as a choice on the Display/Auto Review2 page (below) that can be assigned to a C button. Posting to instagram). great astro photography source for what you are looking for, *not specific to your camera, just astro in general. Therefore, I am looking for another lens and come across the Sony … In particular, many stars look green, from the dominance of green-filtered photosites on Bayer-array sensors. The other Live View function that works well, but also needs assigning to a C button is the Camera Settings 1 > Focus Magnifier. At F4, you should push the shutter speed to 20s. Plus, the Sony was far better than the Canon 6D MkII’s “ISO variant” sensor. See what that gets you. All cameras show an equal number of stars recorded. It is possible some of the artifacts I saw are due to ACR not handling the A7III’s .ARW files as well as it should. Also the A7iii can handle higher ISO. I list it as just “good” for time-lapse work only because it will not be fully compatible with some motion controllers and rampers. Also, it's a digital camera, just play with the settings, you're not going to waste any film. This feature is little known and utilized, and only Canon full-frame cameras offer it. SONY FIELD ILLUMINATION #2 – Another example taken in twilight to accentuate frame illumination shows the same shadow vignetting and the slight magenta amp glow at the left. Sony doesn’t have an “a” model mirrorless. They can cost anywhere from $100 to $400. I just got my Sony A7III with the 24-105mm G lens. The images shown here were shot at lower ISOs to underexposure the dark scene by 2 to 4 stops or EV. All were taken through a 130mm refractor telescope at f/12 using a Barlow lens. But this is a tough call. UNCOMPRESSED vs. COMPRESSED DEEP-SKY – A real-world deep-sky example shows the same comparison. Wow! I was shooting on a Canon 70D & Sigma 18-35 f1.8 and just switched to the Sony A7R III & Sony 16-35 f2.8GM for Astrophotography but unfortunately, I don’t find the combo sensible enough. But … when well exposed, such as in tracked deep-sky images, the 6D MkII performs well. Thanks for reading! But when shooting aurora videos I found, to my surprise, I could “drag” the shutter speeds as slow as 1/4-second, fully 4 stops better than the Nikon’s slowest shutter speed of 1/60 second in Full HD, and 3 stops better than the Canon’s slowest movie shutter of 1/30 second. To get the most out of the Sony for deep-sky imaging you would have to have it modified by a third-party, such as Hutech, Spencers, or LifePixel though, as of this writing, none list the Sony A7III as a model they can modify. The 2008-vintage 5D MkII had a 5-frame buffer! This is from a thin metal mask in front of the sensor. What’s going on here is a mystery – it’s a combination of the cameras’ unique Raw file formats and the de-Bayering routines of all the many Raw developers wrestling with the task of rendering stars that occupy only a few pixels. The Canon does show more noise than the Sony. No luminance noise reduction was applied to these images. My Sony A7 III Camera Settings for Portrait Photography Most of the portraits you see on this site were shot with a Sony A7 III camera. Really Canon? An issue that, to me, has a more serious effect on star quality is the propensity of the Sony, and to some extent the Nikon, to render tiny stars as brightly colored points, unrealistically so. Conclusion and Verdict. I shot with the Sony A7III on Single shot drive mode, on Continuous Low drive mode (with the camera controlling the shutter speed in both cases), and a set with the Sony on Bulb and the shutter speed set by an external Vello intervalometer. I wanted to reach out to the community and see if anyone has great astrophotography settings they've used. While you can look through and frame using the EVF as you would with a DSLR, you are looking at an electronic image from the sensor, not an optical image from the lens. An example is in a 4K video I shot on May 6, 2018 of an usual aurora known as “STEVE.”. This might be an aid, or an annoyance. Before starting to work on your composition and exposure, let’s check some preliminary settings in the menu: Choose RAW for the File Format and select Uncompressed for the RAW File Type. No noise reduction was applied in processing. When used with the Genie Mini (below) the Sony fired at only every other pulse if it was in Single shot mode, an oddity of Sony’s firmware. And neither are 4K. I used the Metabones Canon-to-Sony adapter when attaching the Sony to my telescopes using my existing Canon telescope adapters. This is really pixel peeping at 400%.
