The ergonomics of this camera is very comfortable to use compared to previous 7r models. The enlarged back button, larger grip, and camera-in-hand feel are all welcome. Fast focusing, focus tracking and focus point color also deserve praise. However, the need for Gmaster lenses to really see the difference in image quality wasn't clear to me before I bought the A7riv. Spending $3,500 for the same image quality as a 7riii with the same $1,000 less lenses doesn't make much sense unless you're willing to shell out $1,500 to $2,500 for premium glass. If you don't need to print large images, why would you need 60 megapixels? In fact, uncompressed images are over 120MB in size and occupy most hard drives. The 42 megapixel resolution delivers incredible sharpness with virtually all Sony lenses, including Tamron and Sigma Art (Sony) lenses. and if you're shooting at 10fps, you'll have to wait for the buffer to slowly empty before you can change settings, which can result in frame loss. If you're a professional photographer (I doubt anyone will read Revain reviews) and need prints larger than say 30x40, then what's the point of higher resolution sensors? I've been shooting with the A7riii for a few days after returning my IV and I'm amazed at the quality of the images I get with the Sony 24-105 f4, Tamrom 17-28 and Sony 50 f1.8 get. Spend the extra money if you feel the need, but I doubt you'll see any improvement with regular photography. Save $1000 and buy more lenses for your A7riii you should definitely try before considering the A7riv.
