    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.

    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 focusingCons:-touchscreen limitations, can only be used for focusing-only one uhs-2 slotI have attached some images i have recently taken with the camera as well.

    I'm going to write a more thorough review here but i wanted to leave my initial impressions for first 10 minutes of using the camera. none of this has to do with photography/images in this initial review.1. bought this in amazon warehouse used department and upon receiving it, i checked shutter count and it was 5! this is basically a brand new camera. ZERO scuffing on body. absolutely pristine.2. firmware update from 2.00 to 3.01 went smooth and sony's windows10 software utility was flawless. much better than canon's archaic process (which is easy but just archaic -- no installer)3. SOLID feel. my hands arent huge. but after a lot of complaints i've read that its a tad too small, i think for larger male hands, it could be. only my pinky on right hand grips halfway but i use it to cradle the bottom and the left hand cradles the lens. i have no complains here. I found previous camera (5dm3 canon) was chunky and big and caused fatigue but so far this camera is much lighter and i think it will be easier on my wrist fatigue. I would say the sizing here is very similar hold to canon SL1 SL2 SL3 mini DSLR series. Very compact and travel-friendly here.4. LOVE the button customization here. REALLY REALLY helpful. Latest accumulated firmware update 3.01 allow for more button customization functionality. I have yet to sit down and customize everything... this usually takes a good month for me, so i'll update this review completely after a good session of shots.5. my refurbished version came with NO battery -- i am able to buy NP-FZ100 RAVPower [Upgraded] found in amazon third party sony batteries on the latest 3.01 sony camera firmware. i'm very happy because theyre better value and sony isnt making a fuss with this in their firmware. Canon LOCKS you in on canon batteries and chips them so third party batteries dont register or function well with updated firmware. I understand the reasons why canon would do this (proper camera function guarantee, and prevent breaking electronics) but for me, i prefer the company leave it to customer to take that risk. Camera companies should just log the fact that third party batteries was used on the body into NV flash (when it comes to warranty discussions).6. Articulating LCD is really annoying... just articulates out and up and partially down facing. why bother? Sony really needed to copy canon here with FULL articulating LCD. but this is better than nothing....7. LCD touch screen is crippled. sony firmware crippled the touchscreen interface big time. You cant touch the screen to register input. there are limited screens where your fingers can input change. the rest is dial/OK based. why? Sony again should copy canon/nikon.8. Menu system is more or less really similar to Canon's but just poorly organized. I wish companies would adapt the UI for touch screen interface rather than carry on with same UX design and just add touchscreen here and there. I honestly feel that canon's been improving this in the recent past (especially with "Q" setting) but the industry needs to take a step back and advance the UX for touch screen.9. I wear glasses. the VF so far is decent Dioptric adjustment is great. I think as a small tweak, i would buy a larger cup (third party eye cup around 20$ here on amazon) to get a bit more separation from LCD screen and nose as well as seal up the lighting a tad more but no complaints as is though.That is all for now..... i'll report back after a month or two shooting around.

    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 ability3. HLG color space, no overheating4. 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 criticalThe 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.

    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.
