- AmazingLove everything about the camera and the focus system for Birds in flight. It's another world makes photography fun again.
- A complete package!I've had this camera for about 1 month at the time of writing this, and I can truly say that its a beast of a camera. People complain about why this camera has 61MP but honestly, even if it retained the 42MP of the A7RIII, you'd still buy it for all its other improvements. The image quality and dynamic range of the camera is excellent. The 61MP gives you tons of room to crop your images. The AF system for both stills and video performs exceptionally, to the point I feel its closer to the a9 than it is to the a7R III. It's almost always finds and locks on to the subjects' eyes and even when it doesn't, it locks on to their faces. One area of concern I had before purchasing this camera was its high ISO performance. Traditionally, having all that resolution meant that noise would become more obvious at high ISO values. I was pleasantly surprised to see that images were usable all the way up to ISO 16000, after which the color fidelity of the images start to get compromised (a green tint starts creeping into the image) In conclusion, you're not going the get the same kind of high ISO performance as say the A7III. But its definitely competitive, especially when compared to other cameras with high resolution. (eg. 5DSR and D850) Video performance of the camera is also very promising. 4K footage is stunning in both full frame and Super35/APS-C mode. When it came to 1080p video I was a bit surprised. Full frame mode looks amazing but when I switched over to Super35 mode, the video quality dropped drastically, to the point it almost looks like 720p. Moire and aliasing was so prominent. I'm unsure if this is an issue specific to the a7R IV but I've ended up just using the full frame mode when shooting 1080p. If there is one thing I wish Sony could address in a firmware update, it would be to enable medium and small RAW shooting options. Though 61MP is excellent it'd be nice to shoot at a lower resolution and to perhaps attain better noise performance. All in all, its an amazing camera!
- Thee best stills, landscape camera of 2019-2020So, honestly so much is good with this camera I'll make it quick. This is literally the best stills, protrait, landscape camera there is on market in 2019-2020 and probably will be for 2021. This is comfortable in hand, it takes sharp images, definitely geared for the stills person but I've gotten some ... great moving sports shots, great 4k video, and everything else. Like you could not go wrong. Heck, 5 years from now this camera will still be a serious contender. All a camera is a tool and you make it work. This "tool" in particular though will really help you do your craft. When shooting with it the camera just works with me becoming an extension of my visual art, when I'm doing protraits, landscapes, photo journalism it disappears and becomes part of me. The only cons are the touchscreen is only useful for selecting focus points. If it worked for menus it would be a huge improvement! The other the other downside is the menus. Which really aren't too bad especially after you get the hang of them. Show more
- Just great!Early days yet, I only had it for 2 weeks. But certain things stand out immediately apart from the mind-blowing 61 Mpx detail. Ergonomics: A7 which finally feels right in the hand from the moment you pick it up. New buttons and their locations - fall naturally under you fingers, the joystick particularly ... useful. Huge amount of customisation incl. 'My Menu', where you can keep the most used menu options for quick retrieval. The viewfinder: you forget it is electronic - looks very natural, without any graininess and even its standard frame rate gives a smooth viewing experience. Huge dynamic range. Manual focusing, is finally possible (even pleasurable) with great precision even with the old lenses (via adaptor). I didn't need 61 Mpx, but thought it worthy upgrading from A7RII for many of these features. But 61 MPx is great: much better images even if you only output them at 1920x1200 or similar. But you might need a new computer if you mainly shoot RAWs - the 60 MB files are quite demanding. All in all I'm in love with it! Show more
- Spectacular camera in all ways!I have been totally happy with the Mark 4 in every way!
