This lens is for sale local to me and there isn't any data on it at Dyxum. seller says it needs to be stopped down to F8 to get sharp but does anyone know what the IQ is like with it? if it's already not too sharp what is it like with an TC on it? f4.5 is pretty quick even if it is soft and the asking price is $300cdn it's not the mirror lens but it's cheaper sharp at F8 and no donuts and might work with a TC

DO IT.

I think it's the 5.6 APO just misstated as a F4.5. I see samples for it and they look pretty good for the price. might make my trip to point pelee more interesting if I go.
