User Reviews about Canon E-58U 58mm Snap-On Accessory Lens Cap

I could not get the Canon E-58U lens cap to fit on my CanonPowershot SX20IS. I am returning it. The 58mm UV filter did not fit either. I will probably go on line with Canon to find a UV filter and lens cap that will work. -- Does not fit on Canon PowerShot SX20IS

Bought it to protect my Hoya HMC UV(C) filter 58mm, which is protecting my Canon HF-S100. Works perfectly! (Just need one of those cap-strap things so I don't loose it.)

P.S.
I also have the Tiffen UF Protector filter 58mm that I was using on the camcorder before the Hoya. This cap works on it too. (BTW, the Tiffen filter showed signs of diamond flaring so that's why I bought the Hoya...) -- Will fit on Canon HF-S100 w/ Hoya or Tiffen filter...

The len cap itself is in good condition; however, the packaging is simple and cheap, in a small stabled plastic bag, which made me wonder how Canon could sell its product like this.. -- Good item,
