but is there any sort of conversion factor for the FS 700 when using the adaptors and different lenses, 'A mount' lenses in particular?

I seem to recall reading somewhere that it was x .9....is that right?

Has anyone had an ultra wide on one yet.

Thanks,
Al

Conversion factor compared to what? 1.5x compared to full frame, ~0.9x compared to a 7D

Noah,

With my XL2, when I use an EF lens with an adaptor I have a multiplication factor of 1.7 (I think, I can't honestly remember)

So my 500mm lens is now a 850 (35mm) equivalent.

Adaptors itself should not alter the crop factor.
It´s just a usual Super35 Sensor.
