I put the Leica 280mm f/4 Apo-Telyt-R on both the a7R and a7RII, mounted the lens collar to an Arca Swiss C1 head on a set of RRS TVC-43 legs, set the whole thing on a vinyl tile over 6 inch concrete floor, and made some slanted edge photographs at various shutter speeds. With the… [Read More]
RRS a7II and a7RII L-plate compatibility
From the mailbag: Could you please confirm (or not), that L-bracket for A7-II fit A7R-II without problems or A7R-II needs different L-plate? I have both the RRS a7II L-brackets and the bottom plates. It appears that the bottom plates are just the bottom part of the L-bracket. Both fit the a7RII just fine.

However, I’m concerned about low light shooting. Will this camera give acceptable images for reproduction at high ISO?… [Read More]
Sony a7R, a7RII shutter shock with 180/3.4

The protocol: The cameras: the Sony a7RII and Sony a7R. The lens: the Leica 180mm f/3.4 Apo-Telyt-R The filter: Heliopan 77mm variable neutral density. The lighting: a… [Read More]
a7RII bulb mode spatial filtering at ISO 100, 400, & 1600
I was asked if the spatial filtering mentioned in the previous post that takes place in bulb mode at ISO 6400 also happens at other ISOs. I tested three of them. It looks like the filtering is nonlinear, since it has different effects at the different read noise levels of different ISOs. I assume, but… [Read More]
