Rishi Sanyal, one of the reviewers on DPR, mentioned that he was seeing parasitic interaction of Sony a7R shutter shock and optically-stabilized (OSS, in Sony-speak) lenses that meant that users were often better off leaving OSS turned off. I thought I’d do some testing. I mounted a Sony 70-200mm f/4 OSS FE lens on an… [Read More]

Shutter shock revisited
From the mailbag: I see you have a Sony a7 II. Does the internal stabilization help with the shutter shake? The a7II doesn’t suffer from shutter shake, if you use electronic first curtain shutter. If you turn EFCS off, it does, but you only would do that if you were going to use a very high… [Read More]

I mounted a RRS L-plate to the camera, clipped it in landscape orientation into an Arca Swiss C1 head which was attached to a set of RRS legs. No special lens-bracing hardware. I mounted a Singh-Ray variable… [Read More]

In the previous testing, the lens was the same for the images made with both cameras. Not just the same model, the very same lens. Since handheld testing requires… [Read More]
