This is a test shot to compare a Fluorite/Quartz lens with a "normal" lens for UV photography. The shots show one each per row. All done at f8 and using the new UG11xx Baader filter for the UV shots. The images are cropped/sized for about the same size for comparison. Focus was NOT completely identical. And your guess is? Would you consider both lenses for shooting UV or just one of them?? {} [Nikon D70 + Baader UG11xx + lens. UV shot about -10EV compared to VIS shot, identical postprocessing and resize for same appearance due to different focal length]
Normal - Quartz. Of course I have no knowledge of UV photography but thought it would be fun to guess. Lovely images.
Thanks Gordon! Would you be so kind, if you have the time, and evaluate both lenses from your personal viewpoint a bit more detailled - I would like a second opinion... Here and here are high resolution images. Thanks, Klaus
The lower images are in much better focus. I will guess that is a result of a better spectral window provided by the quartz lens.
my guess is the upper set is the quartz. they seem to have more contrast and more detail than the lower set. I assume post processing was the same on the upper and lower pictures. however there seems to be more of a focus shift on the upper set which would make me think that is the normal lens. tough call. i would definetly use both for UV shooting.
My guess is, that the upper photos are shot with the quarz lens. It looks sharper and has more contrast. is the post processing on both the same? difficult...
More examples shot with the "normal" lens, here the "classic target": {} {} Details (100% crop): {} {}
Btw. the first row was shot using the fluorite/quartz lens (Coastal Optics), congrats to the ones who got this right!
