I tried it carefully today with my 180 f2.0 and it fits without hitting anything. Strangely though the aperture shown in the viewfinder is now 3.4 . I expected 2.8.Now that i,m at last developping my own film i,ll do a ring around test and will check the true aperture of the combo as well. best regards,simon jessurun amsterdam,the netherlands
