Comparison of Lenses for UV Photography

This was a test of three dedicated lenses for reflected UV Photography:
1) Nikon UV Nikkor 4.5/105mm
2) Coastal Optics Ultra Micro Apo 4.5/105mm
3) Zeiss UV-Sonnar 4.3/105mm for Hasselblad

Page I:
Mini images show performance in consecutive order:
f4.5(4.3)/f5.6/f8/f11/f16/f32
LEFTmost column: visual performance
2nd to left column: reflected UV performance (300..400nm)
Right column: comparison visual - UV performance
Rightmost column: Vignetting

Page II:
These three images on page show the difference due to shift in
focal length between visual and UV etc. UV Nikkor leftmost,
Ultra Micro Apo middle, UV Sonnar right.
