Hi all,
We're now looking at buying a Micro35 adaptor, but I have to admit to being slightly unsure as to whether we're going to need a whole new lighting kit to go with it!
Currently I'm using a range of fresnels from 650w - 2Kw, plus the odd redhead and a couple of inkie-dinks (150w).
My thinking is that I'm going to lose 2 stops of light through the adaptor, plus however many stops the "taking" lens is giving us - so on our Z1 we're talking a minimum effective f-stop of about 2 (the Z1's stop zoomed in) - 2 stops (the adaptors loss on the ground glass) - 1-3 stops (the taking lenses maximum aperture) = about f5.6 - f11!!!
Given that, on an average interior lighting setup, I'm at about f4 now, that's put me something like 1 to 3 stops short of an exposure, so I've got the option of (a) adding a load of gain, which I'd obviously like to avoid or (b) putting something like 4 to 8 times the light into the scene...
Has anyone got any experience of shooting with these kinds of adaptors in interiors (we've shot with a mini35, but largely for the reason that the entire shoot was exteriors!) - is it simply a case of going back to what you might call "old-school" lighting practices - i.e. 5k Brutes everywhere, etc??
