As it does not have the same coatings as FD lenses, it gets a bit duller under bright sunlight but wow, I got this lens as a test on a local shop and was shocked on how sharp it is wide open. Payed $25 for it, including case and metal hood so it was a no brainer. Totally love it!
This one makes very good n sharp pictures. Love the output. Sold it for 135mm 3.5 fd mark 2 because it was so not comfortable with my camera. Loved the pictures though. Recommend to anyone who wants to flex their muscles.
