overrated

This is my first L lens. I own a Canon 50 f1/8 and also a 100 f2, both
fixed length lenses. My rating is not so much to say that this is a bad
lens because it's not. For 600+ dollars it is just extremely average. I
would recommend looking at aftermarket lenses before buying this one.
You could save a lot of money. |
