Sorry - Another question - When using a 35mm , 85mm or 115mm lenses, albeit 3.2 or f4, the camera body still goes to f2.8 . So do I need to compensate for exposure to the difference of fstop on the current lens in use. As in open up a half or full stop for the 3.2 or f4 equivalent. Im just not understanding what the f# means on these lenses. Is it just a matter of compensating on the ASA ????????? Nothing is mentioned in any of the manuals I have.
Thanks
