Thanks for all of your opinions..the fact is.I havebeen trying to shoot with this new lens... a canon FD 100mm macro lens in which the apeture does not work.. meaning I can move the lens apeture for stopping up or down. but its disfuctionable...
SO the apeeture is wide open and not F/stops are usable with this broken lens...however...I have found some amazing like/ness of the coin...true color...even thought the lens has noooo...F/STOP that work..But with old school lenses, I have often found outI can use it to a certain perspective...
withought a functioning apeture for this macro lens.....I can't use it at all levels..the key is to find out where I can use it...Due to the inabillity.. of F stops...you can see. some trouble I may have./I must say...
its really a sharp crisp lens.....even thought I have so much work on lighting.... tooo much
but I thankyou for you info...
