Tonight Jeyhan, Jeff, Sarah, and I tried a Mexican restraunt that Jeyhan and I have been driving past for a year and saying, “we really should try that place”. Other than being accidentally sprayed with Sarah’s (not mine) hot cream of corn soup it was a fairly enjoyable meal. As an added bonus, it’s only a short walk from home.

Free Lens Hoods.

It took me forever to find something other then just conjecture on the effectiveness of UV filters. It would seem a pretty logical thing for filter manufacturers to publish their transmissions graphs but it doesn’t seem like any of them do (forum posting suggest B + W will provide them on request).

Here is an actual test of UV filters.

Note that the B + W has the best visible light transmission and is available with a multi-coating. Looks like a good lens protector to me although it’s pretty worthless as a UV filter.

But only in Europe.

I’ve discovered a wonderful and detailed explanation of diffraction in photographic lenses and how calculate the effect relative to the pixel scale of your sensor. It also includes a couple of nice interactive examples and an online calculator.
