With its latest model, the 24.2-megapixel A7 III, Sony has created a near-perfect all-around camera. It has the best mirrorless autofocus system on the market, sharp, full-frame 4K video, high shooting speeds worthy of a sports camera, and excellent image quality.

The A7 III has gained a bit of weight (50 grams) over the last model, but for a full-frame camera, it's still pretty light. It tips the scale at 650 grams (1.43 pounds), considerably less than the comparably priced, 750-gram Nikon D750 DSLR, for instance. The body has a pleasing heft and a size that's great for photo shooting and even better for video, where extra weight actually helps with stability.

The higher-resolution A7R III has a brilliant new 3.69-million-dot OLED electronic viewfinder, but the A7 III's EVF is the same as before, with 2.36 million dots. That's not surprising, considering it costs $1,200 less, but the problem is that similarly priced rivals, the Fujifilm X-H1 and Panasonic GH5s, both have similar, higher-resolution 3.69-million-dot EVFs.

Sony did increase the magnification on the A7 III's EVF a bit, but that just makes the lower resolution more obvious. It was, however, quite responsive, activating quickly when I put my eye to it.

The rear display has touch capability, but you can use it only to change focus. That's unlike the touchscreens on the aforementioned X-H1 and GH5, which also let you tweak menu settings. The new display is a bit dimmer than its predecessor's, so it can be tricky to use in sunlight, even at maximum brightness. As with all other Sony mirrorless cameras, the display only tilts and doesn't flip around -- unlike on the GH5s and certain Canon DSLRs -- so it's not very useful for vloggers who like to shoot that way.
