Sorry Götz, you’re right, it’s the T2
I never use RAW for photogrammetry. I use an Orangemonkie Foldio360 Turntable, which triggers the shutter every few seconds, for 48 photos per 360, so the buffer fills up and the camera can’t keep up if I shoot raw, and I don’t see an advantage in my results anyway.
What I’ve been told so far is, that for magnification upto 1:1, in camera bracketing / stacking is fine, but beyond that, say 2:1, 5:1 etc, you may be better off with a rail.
The Wemacro rail has shipped, I’ll post results as soon as I can, but I’m leaning towards also getting an OM-D or some other camera that does bracketing… annoys me that Sony doesn’t implement it.
