Sony Alpha 7R calibration (full frame sensor)

[davidpmcg]

Hello All,

I have been using an EOS 70D to capture images of bones on a turntable. Yesterday the shutter packed it in (in fairness I shot about 20k images in the past few weeks), and I have been loaned a Sony Alpha 7R while my EOS is being fixed.

The Sony Alpha is a full frame sensor. I have included a number of scaling items in the shots to enable bone measurements later, must I  calibrate the Sony in processing? If yes, how?

Cheers

davidpmcg, The folks at Agisoft may have a different answer but I'm going to say, "no" - you don't need to do anything to calibrate for the new camera.

I say this based on my experience shooting models with a variety of cameras on the same shoot.  I have shot people with crop sensors and full-frame sensors at the same time, fed all the images into Photoscan and had absolutely zero problem.
