Originally posted by cbope It's not very convenient to use a blower every time I replace a lens cap. Plus, I may be bag-less and just carrying the camera/lens on a shoulder strap which I do quite often. Then where would I keep a blower? On second thought, don't answer that, please
... unless if you line your shirt pocket with a zip-loc bag. A small zip-loc bag would do the job (in my country, pharmacies package pills in small zip-loc bags instead of amber bottles. Those little plastic bags are really handy.) Flip the top 1/4 of the bag down to make a nice, stiff rim that keeps the opening from closing. Then, you may keep whatever you want in your pocket lint-free.
P.S. Every human comes with two blowers. Blow with your mouth without spitting. Alternatively, you may fart
