Re: Pentax curved filters...

Do I see a WikiPedia article in the making?

For what it's worth, the close-up "filters" are curved too.

Even the best and most expensive filters have parallel planes

Ah, except for the old Pentax "ghostless" filters that were curved.

Excellent. I'll add that to the next version.

Thanks.
