fotonunta

When I first purchased the lens I was very happy. I had to adjust to some features and soon found out that my Tiffen variable ND filter did not work well with the wide angle, needless to say I was very upset because I do alot of photography on the water. Only after 4 months of using my new lens it started creeping down when in use, I also shot from on high straight down or product photography. Of course can't return to B&H and Canon said I could send it back for tightening but don't be surprised to find out that it cannot be fixed because it is a normal feature for this lens.This was my first L-Series lens and I am beyond disappointed!!!!!Yes the clarity is good but if I can't use it to shoot everything without it being a pain, I would have never bought it...or at least if I had read the reviews first I would have know about this issue I could have purchased with this first hand knowledge instead of being surprised. I would recommend the lens for regular photography because it does have very good quality glass.
