Compared to the 2 Canon DSLRs I have owned in the past, it blows them out of the water in terms of auto focus speed and accuracy. For low light, I've never seen anything like it in the consumer market, not counting the A7s ii which I haven't tried yet. The version that I bought came with the kit lens and it's performance is fine. It's not the best to use for the ultimate low light capabilities, but it's reliable enough. Interestingly enough, the kit lens even has firmware that you can update. I have successfully used my Canon glass with it using a Simga MC-11 adapter. The Canon 17-40mm f4L and

This camera has changed the GAME! I am so incredibly impressed with this quality of the photos it takes. Even with the kit lens, I’m so impressed! I had bought a brand new Canon Rebel T7 and put a 50 mm & 85 mm lens on it and this camera with the KIT LENS blows that camera and prime lenses out of the water! I love this camera so much. It’s the best purchase I’ve ever made! The touch focusing feature is awesome. The auto ISO is incredible. The shutter sound sounds so boujee (LOL) when I snap a picture with this camera, I just feel like a professional! I’m trying to start a photography business
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!
Very nice camera
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 equipmen
The Sony A7III with the 28-70mm f/3.5-5.6 kit lens has been a great transition for me from the Fujifilm X-T3. The first thing I noticed was how much simpler and more intuitive the menus and button layout are—getting used to it was effortless. While I do miss the X-T3’s 10-bit video capabilities, the full-frame experience is on another level in terms of depth and low-light performance.One of the most surprising aspects has been the battery life—it’s incredibly good. I initially thought about getting a spare battery, but for someone like me who isn’t doing heavy professional work, it doesn’t fee
I've had this camera for about 10 months now and it is probably the worst photographic decision I have ever made. I only wish I could have returned it while I had the chance.Let me start of by saying I've been a professional photographer for 15 years and mostly photograph models in a studio setting or outdoors. I use natural light and also strobes. I started with Nikon, went to a Canon 5dmkii, have had other canons and also 3 fuji x series camerasFirstly, what kind of company ships a $2000 camera without a battery charger? I get it, it can plug into your computer to charge or car adapter via U
Excellent camera with amazing image quality. Autofocus is fast, low-light performance is great, and it’s perfect for photography. Very happy with this purchase.
