Cory:


I agree. However, Tamron caps are a bit expensive. Check eBay for center-pinch caps that are usually much cheaper and work just as well. There are several designs, mainly in the finger-holds. SOME are a bit wider than the filter/lens and may interfere with installing or removing the hood, but most work fine. Unfortunately, while I know which of my caps has that problem, I don't remember from whom I bought it, plus, some sellers list more than one design. Some come with lens-keeper strings (REALLY useless!). I remove the strings and use a pair of diagonal wire cutters to cut off the eyelet the string was attached to and file down the "nubs," if needed (not often) with a nail file.


I've developed the habit of usually (heck, I'm 62!) putting the lens cap in my pocket. I was helping a guy learn to use his Rebel last summer and reminded him several times to put the cap in his pocket. Once, he sat it on a table. While he wasn't looking, I picked it up and put it in my pocket. A while later, he looked for the cap. He couldn't remember exactly where he'd left it--the table where he had left it was NOT the first place he looked. [6]
