This would be tougher to eliminate in deep-sky images where the extreme contrast boosts we typically apply to images of nebulas and galaxies will accentuate any odd glows. The Canon shows a darker sky as its images were taken a few minutes later. Up to now my report on the Sony A7III hasn’t shown as glowing a performance as all the YouTube reviews would have you believe. Here I compare all three cameras for this effect in two-minute tracked exposures taken with Long Exposure Noise Reduction (i.e. The Nikon seems to discolor stars only when LENR is applied. It did not. The Sony still showed some discoloration artifacts and added noise when boosting images by +4 EV that the Nikon did not. Quick Answer: The 5 Best Rated Lenses For Sony a7iii For 2021 Sony SEL50F14Z Planar T* FE 50mm f/1.4 ZA Lens It’s fair to say that this camera is a work-horse in any situation and comes at a reasonable price. My current gear list; Nikon D5300. 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). These were then boosted in Adobe Camera Raw by 2 and 4 stops in Exposure Value (EV) to compensate. Certainly not as good as the Canon rendered with Camera Raw. Reddit's most popular camera brand-specific subreddit! The Sony A7III’s screen is, but only to select an area for auto focus or zooming up an image in playback. A lot of people buy a nice camera and then use it with all the default The design lends itself to video shooting, with many mirrorless cameras offering 4K as standard, while often in DSLRs only high-end models do. Those underexposed images were then boosted later in processing (in Adobe Camera Raw) by the required Exposure Value to equalize the image brightness. But I find I often do use the Canon and Nikon in-camera intervalometers for simple shoots, and for cold winter aurora shoots. Again, the differences are in images vastly underexposed. 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 other Live View function that works well, but also needs assigning to a C button is the Camera Settings 1 > Focus Magnifier. I tested a Sony A7III purchased locally. Sony’s A7III camera has enjoyed rave reviews since its introduction earlier in 2018. https://www.youtube.com/watch?v=en4eeK33UoE This should help you! I put this on C1. I used the Metabones Canon-to-Sony adapter when attaching the Sony to my telescopes using my existing Canon telescope adapters. In new models, Sony now offers the option of a final “My Menu” page which you can populate with often-used functions from the other 35 pages of menu commands! Nevertheless, for the demands of nightscape and deep-sky shooting and processing, I suggest shooting Uncompressed Raws. But this is a tough call. The Star Eater is gone. In Continuous mode, I think the effect is still there but maybe a little less. 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. 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! 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. Why would that be? Compressed files showed more noise and magenta discoloration in the shadows. One battery can get you through a night of shooting, though performance will inevitably decline in winter, as with all cameras. You can see the Milky Way! 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. This makes it so easy to frame nightscapes and deep-sky fields. Camera Settings 2 > Live View Display > Setting Effect ON. Again, here I show only the Sony and Nikon, the two “ISO invariant” cameras. Now it’s time to get deep into those camera menus and show you how I setup my camera to shoot surf and ocean images. Price expected to be $5,999, This software lets you test movie lights without leaving your home, This trippy macro timelapse turns shriveling of plants into art. Star Eater Noise (most noticeable in the trees) is reduced and stars are very slightly softened. I list it as just “good” for time-lapse work only because it will not be fully compatible with some motion controllers and rampers. SONY REAL-WORLD LENR COMPARISON – A real-world example with the Sony, with a properly exposed nightscape, shows that the ill effects of using LENR don’t show up under normal processing. This allows the Live View image to reflect the camera settings in use, better simulating the actual exposure, even without Bright Monitoring on. SONY TILTING SCREEN It tilts up and down but does not flip out as with the Canon 6D MkII’s. This lens balances nicely when paired with the Sony A7III and has a sturdy feel. Alan Dyer is an astrophotographer and author of astronomy books based in Canada. Only being f/4 is gonna limit you. And star colors are not affected, though very small stars are sometimes green, an effect seen in other cameras due to de-Bayering artifacts. STAR EATING vs DRIVE MODE – This series shows star sharpness in images taken in Single and Continuous drive modes, and in Externally Timed exposures. It controls the Sony through the camera’s Multi USB port. I just got my Sony A7III with the 24-105mm G lens. I would assume not, but not having an a7s (either Mark I or II) to test I can’t say for sure. Introduction The Sony … 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.

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. Try 24mm, f/4, 15 seconds, iso 1600. All images are equally well exposed. NIKON WITH AND WITHOUT LENR – Dark frames taken with the Nikon D750 under the same circumstances and processed the same show none of the residual hot pixels and added background noise when LENR is employed. Video Capability  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. The Canon is free of any such issue – stars are naturally colored whether LENR dark frames are applied or not. ISO INVARIANCE CLOSE-UP – A closeup of the scene shows the ISO variant Canon exhibited more noise and magenta discoloration in the +4 EV boosted image. With a mirrorless camera the sensor is not set far back in a mirror box, as it is in a DSLR. It’s unfair to blame just the hardware or the software. STAR EATER DEEP-SKY #2 – Another example with 4-minute exposures again demonstrates no problems recording faint stars. MF Assist: On – a great feature that automatically zooms in when you move the focus ring in manual focus mode. More rapid-fire burst modes and quieter shutters are a plus for action and wedding photographers, though they are of limited value for astrophotography. As soon as the Sony a7S was announced, I knew I had to try it for astrophotography. While it does have a 1 frame-per-second movie mode in its “Slow-and Quick” functions, that’s not sufficient for night time-lapses, plus S&Q mode only works with HD movies, not 4K. No luminance noise reduction was applied to these images in processing. CAMERA TRIO – The Sony A7III, Nikon D750, and Canon 6D Mark II. He fell in love with photography in 2013 when he got a camera as a birthday present. This does a fine job smoothing frame-to-frame flickering in time-lapses, something the Canon cannot do. SONY FIELD ILLUMINATION #1 – The full field of a deep-sky image taken through an f/5 70mm astrographic refractor shows the minor level of edge darkening at the corners from shadowing of the sensor in the Sony. What’s up guys, Sagi here and welcome to another Tech Gear Talk. UNCOMPRESSED vs. COMPRESSED at -4EV – The same scene but now underexposed by 4 stops and boosted by +4 EV later shows greater differences. The Sony showed poor deep-red sensitivity, though not unlike other cameras. In the Sony, LENR did not eliminate all hot pixels nor the magenta amp glow at the left edge. Sony A7 III, A7R III, A9 Astrophotography Settings You have found a nice spot, you have your camera on the tripod and the main dial is set to M (Manual mode). It magnifies the Live View by 5.9x or 11.7x, allowing for precise manual focusing on a star. Assign it to one of the hardware Custom C buttons. One question though, I set Memory 1 to your landscape settings and Memory 2 to Action. The ones taken with LENR on show fewer hot pixels. This is good news, as astrophotography requires fast, high-quality lenses, and the Sony allows more choices. While the Sony has a Bulb setting there is no Bulb Timer as there is with the Canon. That includes simple intervalometers like the Vello, the Syrp Genie Mini panning unit, and the Dynamic Perception and Rhino sliders, to name devices I use. There are many people testifying that the Sony a7III is a great choice for beginners due to its versatility and ease of use. NOISE AT ISO 6400 – At ISO 6400, the Canon begins to show excessive noise, about a stop worse than the Nikon and Sony. Your cameras are getting worse for astrophotography while Sony’s are getting better.Â. Hey Guys, I just got my Sony A7III with the 24-105mm G lens. Hacking Photography - one Picture at a time, I put the new Sony A7III mirrorless camera through its paces for the features and functions we need to shoot the night sky.
