why are people making it so confusing for the OP?
Put simply, ANY lens you put on NEX requires a x1.5 on the FL written on the lens.
Because the focal length does not change, period.
Using a smaller sensor does nothing but crop the image circle from the lens, so it's the field of view that is changing, not the focal length, so using 1.5x the FL is an over simplification of what's happening.
it is an oversimplification but the logic works. it'll only confuse people when you go too technical about it.
