Rokinon 35mm 1.4 vs Zeiss 35mm 1.4 Autofocus Test by David Vogt


Here is a quick video comparison of the autofocus systems of lenses at different price points. The Rokinon AF 35mm FE does a great job against the Sony 35mm Distagon while costing much less.

Download Sony a7rIII Manual Preliminary

This is the manual for the new Sony a7r III / mark 3 46mp full frame camera with touch screen. We think this is a preliminary copy since it does not match the menu of the cameras we played with at Photo Plus Expo. We still think it's enough to feed those waiting for their a7r III pre-orders.

Download the a7r iii manual via Dropbox.

Accessories included with Sony a7r III

Here is the Shoot Mode / Drive 1 menu on a pre-production Sony a7r III showing the Pixel Shift option.




Pre-order your a7r III from Amazon and support this site.


In case the Dropbox link dies, here is the Google link for the a7r III owner's manual.

The images must then be processed and combined in your pc via Sony Imaging Edge software.
