Comments about Tiffen Tiffen 58mm UV-2A Haze-2A (Ultra Violet) Glass Filter:

Feb 2010 - ordered 2 identical filters and a new Canon lense; already have a Canon lense that needed a filter too. One of the Tiffen filters fit both lenses, the other did not fit either one. First filter had classic metal finish; second had new non-glare powder coat finish and that 'thickened' the threads so it would not screw into the lense! Not even the brand new lense that I ordered with it.[...]Until this is acknowledged and fixed DO NOT BUY this filter. And who knows what other filters don't fit. Good luck.
