Speaking of filters, how many of you remember the "Toilet paper oil filters" for cars that came out in the 50s and 60s? My uncle had one on his 57 Plymouth Belvedere with a 318. All you had to do to replace it was unscrew the top cover, remove the old one and replace with a new one.
back in the 40's, thats what they put in the tractors for oil filters, a roll of toilet paper...

In the 20's they only had a screen. No place to put a Sears Roebuck catalog.

For MT, I have UV filters on all my lenses, recommended by my camera store, to protect the actual lens element from scratching and damage, now I hear that that may not be the best idea because of distortion to the image. WOW, I am a bit concerned about using a lens outside without protecting that outer glass, am I overly concerned for no reason, or should we not be protecting our lenses with a filter? Thanks for the response back on this, I have always shot with the filters on my lenses, too afraid I might damage the outer glass!

Protection is ALWAYS a good thing, its just that UV filters are probably not the best choice for it. As I have stated on this forum many times, most manufacturers of filters make a protective filter from Optically Clear glass that is designer to protect that front element without distortion or color casting found in most UV's, especially the cheap, uncoated variety. (And many off-brand filters that claim to be "coated" are little more than a polish job).
My personal preference is the Nikon NC (Neutral Clear) filters for lens protection. They run about the same price as a quality UV but have no effect on your image, meters or sensors.

Immutable laws of optics dictate that light rays, other than those at 90 degrees to the surface, will reflect and refract on entering or leaving glass. The result for perpendicular rays is a change in speed and for all other rays is a change in both speed and direction.
That's a fairly pompous way of saying that I don't use filters for protection because any filter will affect the light path and cause reflections.
This is simply my choice but if you feel you really have to use a protective filter then follow the advice of MT Shooter and use the highest quality NC filter.
Maybe I'm just lucky but, In 50 years of camera ownership, I have never damaged the front element of a lens. I AM careful, I DO use a lens hood and I DO replace the lens cap ASAP; oh! and I AM insured.
As a matter of interest, the oldest lens I have in regular use dates from the early 60's; can't remember exactly but probably '64/5. It's a Minolta AUTO ROKKOR 55mm f/1.8 and here's one I took in February of some new buds.
