Is it a good idea to always leave either a uv or skyligt filter on the lens as a protection for the lens? I hear lots of people recommending that but I thought that adding another glass to the lens will actually deteriorate the optics. Please advise -thanks.

I think it is a 'must' list. 99% of the lenses you see will have this on them.

If u use a pastic UV filter, it will block a small amount if light enter the lens.

If u use a high quality lens, u should use glass UV filter instead but it cost more exp.

It is better to have UV filter on all the time. A lens hook is an additional protection too. :)
i use vitacon uv filter... buy 2nd hand dat time the person gv one... haha...

its better to 'wear a cap' for protection than to reget it later.

the cost of repairing a lens may be more expensive than replacing a crack filter.

I use B&W UV filter in all my lenses except for the 17-35 mm and 12-24 mm (don't use any filter at all for these lenses).

If your lens is a prosumer, i.e. L-glass for Canon, then spend a little more to get a B+W (shouldn't be an issue since you can afford a L). However for dumb people like myself, I doubt I pick up the difference just by looking @ the image ... :D

Why not shoot 2 same scene with/without filters, blow up 20x30 and then see if there're differences?

Why dont you use filters on the '17-35 mm and 12-24 mm' ? Does it spoil the images??

Some filters will cause vignetting... especially wide angle lenses. 17-35 definitely have.

why put a cheapo piece of glass over a $1000+ lens?
