I was taking a bunch of test shots with the A7 III today. As I mentioned earlier the longest Sony lens I have with native e-mount is the 55mm f\1.8. I saw an opportunity to test out the autofocus at a long distance with a moving subject. Because I took this at about 150 feet away I cropped this thing to a ridiculous extent and it shows but also notice that the fox is in focus. Pardon the poor quality of this jpeg (figuring out the new Capture 1 for the A7 III) but this tells me two things.
The autofocus is very, very good.
I’ve got to get some longer native e-mount lenses.
Sonyalpharumors.com has upped the odds of the A7 III being announced tomorrow (26FEB2018) to 75%. Of course the calculus of rumor mongering is far from an exact science, but in this case I think he’s probably right. And just to sweeten the occasion Sigma has announced an FE mount lens. It is an Art Series 105mm f/1.4. And it looks like a beast with its own tripod mount. Looking toward the horizon I hope after the announcement it won’t take long to learn if this new camera has good autofocus. One interesting development in the rumor is the fact that the autofocus system has more contrast detect points than phase detect ones. This continues a change in direction from the A9 which had many more phase detect than contrast. I’ve always thought the contrast detect points were much less functional so I see this as a bad sign. Time will tell.
