So far, I’ve written 18 posts on the prototype Kolari-modified Sony alpha 7II with various rangefinder lenses attached, and also, as a control, with the Sony-Zeiss 35mm f/2.8 FE. The series starts here. Kolari has been shipping thin sensor stack modified a7’s for quite some time, and the a7II sensor and sensor stack are very… [Read More]

Sony a7II IBIS with a 16mm lens
A reader asked if I’d test the in-body image stabilization (IBIS) on the Sony alpha 7II with a really short lens, to add to the testing I’ve done previously with a 180mm Apo-Telyt and the Zony 55mm FE and the Leica 28mm f/2.8 Elmarit-R. I selected the Leica 16/18/21mm f/4 Tri-Elmar, aka the WATE. Sony calls IBIS SteadyShot…. [Read More]
