I love this little lens. For the price it is the best ( value ) lens that I have to date.
I noticed in public people take much less note of me with this lens on my 60D as compared to my 17-50mm which I had hoped would be the case.
It focuses at a closer distance than many other Canon lenses which is very nice at close quarters like seated at a restaurant table, optically is wow very sharp & colors pop.
Everything about it has surpassed my expectations by a large margin.
Though it has not replaced my 17-50 2.8 I.S. as my most used lens it will stay tucked in my bag and always be at hand - its sooo tiny.
Well that's my 2¢ based on this last week.
Wrote this because other reviews here have really helped me so I'm trying to give back in return.
