I just got a russian made zenitar 16mm/2.8 manual fish-eye lens for myInteresting. So presumably the TTL flash meter in the camera does not have the exposure flaw, but the evaluative meter does. The test for this theory would be to use an E-TTL capable flash unit. If you find your flash photos are not exposed correctly when you use E-TTL flash then the theory seems likely to be true.
eos7, shot a trial roll to determine the correction factor for exposure
(the lens is fully manual) and found a curious thing i cannot explain. may
be someone can elucidate me on that. while available light exposure
requires +3 stops compensation, shots made with flash did not change with
compensation. i mean, +3 or -3 stops did not make any difference - they
were all exposed correctly. by the way i was using pop-up flash, not an
external unit for this test roll.
