Actually, lenses minutely 'scratch' every time one physically cleans them, no matter how it's done. Photographers use UV filters to keep the lens surface covered so the replaceable filter gets damaged and not the valuable lens surface.
The X1 has a plastic housing around the lens that isn't threaded. However, you can screw a threaded filter into the plastic and it will stay on after about 1/4 turn. I believe a 67mm works, but do a search to be sure.
While im very impressed with my X1 in both colour, shadow detail and sharpness (esp taking the res into consideration) i find it sometimes a bit bright for my liking. While one can pull back the brightness this is at the expense of shadow detail, and full "off" or full "black" is still the same.
I have read here about Neutral Density filters which can cut back the light and hence make the "full black" darker.
Doing a quick search they don't seem to expensive, they seem to be rated at 2x, 4x, 8x etc.
What is best suited for the X1, does anyone have experience in using one?
Would a 2x be enough or should i go a 4x ND?
Which of the below is more suitable
1. Neutral Density Filters
These filters should suit your normal picture taking requirements and offer lens protection.
2. HMC Neutral Density Filters
HMC Filters are made with 3-coatings on each side for reduced flare and are much better than the standard monocoated filters. Flare is less prevalent and pictures taken against the light are better. HMC Filters allow for 97% Light Transmission.
I tried the HMC 2x neutral density filter over the weekend. Reading some posts here I thought it would help. But I removed it yesterday during the Giants game because it just dimmed the image that I could just not seem to compensate with a recalibration. It wasn't so bad with DVD but SDTV was too dark and lost the brilliant colors
Originally posted by jake14mw Is there such a thing as a "clear" filter, to use just for protecting the lens?
I haven't seen a filter that is literally clear, but a UV filter is usually used for what you are talking about. They are commonly used to protect your lens, and really only cut down on haze a bit.. it shouldn't lower your lumens at all (or negligibly, like any piece of clear material would). I always buy these for lens optics..
One thing I wonder though is if this would trap any excess of heat in? I guess it must not be a big problem since so many folks run filters on their projectors.
