I picked up this Canon 50 1.8 recently. Everything looks decent except for the front element and some traces of bubbling on the very edge of a rear element.
The second shot was taken in my bathroom but I couldn't get the marks to show up very well. After I placed it on a flashlight the details are quite easy to see.
I did some test shots with the lens and plan on developing it later tonight. I paid $160 for this lens, given the scratches are there better condition versions out there to be had for the amount I paid?
