Today I found the first dandelions in this year and shot them in UV.

I used a D200 and I can tell you that the D200 defenitely is a very very bad camera for UV shooting (at least with the strong AA filter in it, with the filter removed the D200 would be very good).
It is possible to record UV, but the exposure times are very long. The shots above are for example 30 seconds at f8 and 800 ISO in bright sunlight.
The shift of focus is insane too.
I really would like to have a D70 now. :frown:

Great shots Joe!

On my old D70 I usually have 2...4" @ISO200 with the new UG11xx even on an just overcast day.

I did some calibration tests with some lenses, have a look at my pbase site, maybe interesting for you.

Cheers, Klaus

If you shoot UV with a "normal" lens, try to focus closer. Use the DOF indicator and adjust the point of focus to about the >closer focus< f8-f11 position. Try that out, worked pretty well for a few of my lenses. But of course a series of test shots with adjusted focus is better, but much more work.

Cheers, klaus

speaking of lenses, what lens did you use for these?

Some results of today also using some old lens. I calibrated
it (i.e. tested out the UV focus and when shooting UV, I change
the focus to that position):
