The Sony 28-135mm f4 Power Focus Lens is Designed for the a7s


Given the fact that the Sony A7s is pretty much designed for videographers, Sony has decided to find a way to support the video front even more with their new 28-105mm f4 G OSS lens. This lens features power zooming capabilities more suited for news and documentary videographers as well as sports shooters.

In our meeting with Sony, they told us that a lot of work went into the design of this lens to ensure that focus breathing didn’t occur at all when focusing in and out, lest it otherwise mess with the quality and framing of a scene being shot. Additionally, the zooming was made to be very silent by using Sony’s SSM motor technology. Otherwise, it features aspherical elements, multi coating technology, and is designed to be very contrasty. For serious videographers, that will mean that you’ll get an extra boost of faux-sharpness due to how the human eye sees blacks. But it will also mean that your color profiles will need to be even flatter. Finally, a lens like this would be nothing would optical stabilization–and of course it’s built in.

Expect this lens to hit the stores at a $2,500 price point.
