In the same price range, Canon EOS R has a better viewfinder. It happens so rarely it’s not a huge deal, but happens enough that I noticed it was doing something weird. The only issue I had was every so often, something would lag and cause the EVF not to turn on when I put my eye up to the viewfinder. The Sony A7 III has the same resolution as the Fuji XT-2, which has always been regarded as a great EVF. I also heard a lot about the Sony A7 III having a lower end EVF, but unless you are shooting it side by side with an Sony a7R III or Sony A9, you probably won’t even notice – the image in the EVF is plenty sharp and has no problem with its refresh rate. Nothing close to being a deal breaker – I just found it strange and partially annoying.
For some reason the Sony takes almost an entire minute to format the card. Using the exact same card, my Nikon D750 can format in about a second. As you can see in the champagne spray image above, big buffers can mean getting the perfect moment.Īnother thing I found strange was just how long it took to format a memory card.
While having a 30 image buffer is definitely manageable, it still means only 3 seconds of shooting when at 10FPS.
Switch to uncompressed RAW and this drops to less than half the buffer size. It’s important to note that this is referring to compressed RAW images, which are a 12-bit file instead of 14-bit. When dealing with the buffer, the Sony A7 III is listed as having a buffer that can hold 76 RAW images. Since I tend to shoot most of my images underexposed a decent amount so I can push them in post, this isn’t really a viable option for me. The only option you could have is to shoot RAW to the fast card and a JPEG backup to the slow card. This essentially makes using the more expensive UHS-II cards pointless if you plan to shoot RAW images to each card. This means that if you are shooting with the camera set to write each image to both cards, the write speed will be bottle-necked by the slower card. Something worth noting is that that the Sony A7 III does support UHS-II fast memory cards, but only for one slot. One other feature new to this round of A7 cameras is the addition of dual memory card slots, which is something that most working professionals place a lot of value on.
