any idea about the focal deviation using MTF B4 adapter ?

PostFri Jun 23, 2017 6:51 pm

Suppose I want to use a MTF B4 2/3" to Super16 Micro 4/3 Adaptor on a BMD Micro Studio Camera 4K, using a J17ex7.7B4 lenses; what will be the (new) focal range using this adapter ? On their web page this information seems to be missing.

The purpose for using this adapter is to avoid vignetting if the 2x extender is not used, while using the camera in HD-only mode; I have no idea – and I cannot check right now – if the capture area on sensor is smaller in HD mode than the full area in 4K mode and if so, I don't know whether vignetting will never occur anyway if 4K is not used.
