Description

Eye AF can now be used with AF-C mode, for fast, effective eye detection/tracking performance when shooting stills. Easy maintenance of optimum focus on moving subjects totally transforms portraiture. Newly developed back-illuminated image sensor & evolved image processing system fulfill various shooting needs with high-quality imaging capabilities that you might expect only of a full-frame camera. Standard ISO range is extended to ISO 100-51200 (expandable to ISO 50-2048007 for stills) while Detail Reproduction and Area-specific Noise Reduction technologies maintain image details and cut noise. High-precision stabilization unit, gyro sensors and algorithms achieve a 5.0-step9 shutter speed advantage in a system that compensates 5 types of camera shake with a wide range of lenses. As well as new capability of recording stunning 4K movies3 through 2.4-times22 higher oversampling, the camera features a new HLG (Hybrid Log-Gamma)4 picture profile, supporting instant HDR workflow. This camera allows silent shooting18 at up to 10fps with AF/AE tracking2. Silence is critical for various scenes, when even slight noise can mean missing a chance at an ideal shot. Capture the peaks of more decisive moments with the α7 III from Sony, packing newly developed back-illuminated full-frame CMOS sensor and other advanced imaging innovations, high-speed response, ease of operation, and reliable durability that are ready for various shooting needs. With outstanding imaging capability and high-speed performance contained in a compact body, the α7 III gives you the power, precision, and flexibility to capture once-in-a-lifetime moments just as you like.

  • A Very Capable Camera Even in 2025
Style: Body Only Set: Base
Still a great camera in 2025 especially considering the economical price you can find it for. I have used it to take beautiful portrait photo shoots, a couple weddings, Milky Way galaxy photography, landscapes and beyond. Solid auto focus when shooting videos. Would love to have faster FPS and auto focus when shooting action shots but I also understand that this model predates a number of those advancements in mirrorless camera technology. ... show more

  • Incredible
Style: w/ 28-70mm Set: Base
Truly a steal. I’ve been skeptical in the past buying used equipment, but this easily saved me hundreds with no decrease in product quality. It came essentially brand new and has been able to produce stunning photos out of nothing. I took it outside and quickly discovered two little hairs on the sensor, which I’m led to believe is why the original seller let it go. No issue to me, a $20 cleaning kit got rid of it. The photos it did appear in don’t at all feel ruined as I’ll just edit them out. Definitely my favorite purchase I’ve made, and I’d recommend it to anyone looking to make an equipment jump without spending an arm and leg. The colors are just great. Love it. ... show more

  • At this price, can't beat it.
Style: Body Only Set: Base
The media could not be loaded. I have been a user of both Nikon and Canon over the past 3-4 years and made the switch to sony in August of 2017. The a7iii is by far the best camera I have used on these three platforms. I previously owned and still use the Sony a6300 which was great for a budget camera but had tons of issues for someone who shoots professionally. I primarily shoot weddings and sports but also do commercial level work on the side. The photos I have provided are my first test of the a7iii in a somewhat warm climate doing both photo and video. Improved Features: 1. IN CAMERA PROXIES... no one talks about this on youtube!! 2. dual card recording ability, dual writing ability 3. HLG color space, no overheating 4. Bright and Beautiful monitor, focus peaking, customizable buttons, uncompressed RAW photo capability, a large buffer depending on card size, and great autofocus with eye AF and face tracking... plus better "color science." Color science means absolutely nothing unless you are delivering a final image or video straight out of the camera, its all subjective and if you want Accurate colors Sony is the way to go. I could rant for pages about "color science." 5. Headphone Jack... Monitoring external audio is absolutely important if you are running wireless mics. I will use this to monitor my wedding ceremony Audio. Things that could be improved: 1. The EVF is not calibrated color wise to match the display screen on the back of the camera... not a huge deal for video but it can get annoying for photo. Know your settings well enough to get you close in photos, and the RAW capabilities in Lightroom will give you some leeway. 2. No face tracking while using an external recorder AND recording in Camera. If you record solely on the external recorder you can still retain face tracking which is not a huge deal, there is an option in the settings but it turns the external screen black. 3. only 1 UHS-II slot. I would love to see two of them. 4. no 10-bit color depth... this is probably coming on the a7siii which I understand, but it would be incredible to get a firmware update on the a7iii, a7riii, and a9 to allow 10-bit color, making SLOG and HLG way easier to expose for and work with in post. Also, it allows creators to keep their a7iii and purchase an a7siii to match perfectly with it. 5. The shutter button is a little spongy... not a huge complaint here because I am being rather critical The a7iii has improved almost all of the issues thus far I have experienced with Sony APS-C Cameras. In my example photos and videos, I used the 70-200 f/2.8 GM (incredible lens). The a7iii lasted 4.5 hours of continuous video and photo shooting to two different SD cards with a completely bright viewfinder and screen with 20% battery to spare... something I could only dream of on the 6300. This is absolutely a professional camera and is reasonably priced for the features it has. if you are looking for a prosumer camera with pro features... you can't go wrong with the a7iii. It definitely is not a cinema camera but will absolutely serve me well until I need to upgrade in the future for both photo and video. ... show more

  • Best camera on the market right now
Style: Body Only Set: Base
Best camera on the market right now. Ive been shooting sony since the 1st gen a7 series, going from an a7<a7s<a7ii<a7rii & now the a7iii. Between the first 2 generations there were limitations that i felt yearning for such as longer battery life, dual card slots & better autofocusing in challenging light etc. The a7rii did so much for me & was way ahead of its time but those departments i mentioned were still lacking & i had hopes of them being filled when gen 3 would be released. When the a9 and a7riii released i was excited to know that they implemented those changes but my pockets weren't deep enough to budget for either of those 2. I stayed more focus on the rumors & hopes of an a7iii announcement not nearly expecting as much as what was to come. Sony hit it out of the park and released a camera that blows all the competition away, somewhat cannibalizing their higher end sales, this camera fills in every space i ever wanted in a camera. Granted theres some things that could be done differently, such as better touch implementation & making both sd slots UHS-2, however those may be wants for others but i have no gripe with either of them. For the large majority of people this camera can do it all at a much more (still high) affordable price point. Unless you have the need for 42mp or 20fps than this is the sony camera to get. It has placed my a7rii as my backup camera & am using the a7iii even over it for landscapes and portraits because the color rendition & joy to use has been improved. I can ramble on all day about all the tech features etc, but if you are looking at this camera & on the fence about it, you will not be disappointed. Pros: -amazing autofocus that covers almost entire frame -large battery -improved color over previous gen -amazing lowlight performance, better than a9 & a7riii, about as good or better than a7sii in certain modes -improved ergonomics -improved menu -touchscreen focusing Cons: -touchscreen limitations, can only be used for focusing -only one uhs-2 slot I have attached some images i have recently taken with the camera as well. ... show more

  • Best Camera for the money.
Style: w/ 28-70mm Set: Base
Was on a Canon RP camera before deciding to upgrade. Was nervous at first because of the fear of the item coming in broken. When I tell you, that I am beyond impressed with this Camera. From how well it functions, to the picture quality is superb, the image stabilization is top tier. The size is amazing too fitting perfectly on my hand. And above all else, how easy it is to handle. The battery life is also another plus, being able to shoot at least around 710 pictures in one charge. Definitely recommend! ... show more
