UV Capable 35mm f/3.5 M42 Mount lens Kit with Macro Mount and UV Filters

UV Capable 35mm f/3.5 M42 Mount lens Kit with Macro Helicoid Mount, Stepping Ring plus Remounted 49mm Baader U Filter. These are used 1960's era lenses that just happen to be remarkably good in UV, although they are often well used, they are all cleaned and tested.
The Baader U Venus filter included in this kit is the best UV pass filter available, this specially adapted 49mm Baader U 365nm UV passing filter is the latest version, which appears to produce more intense colour than the old and does not seem to require to be reversed for photography. The filter passes only a band of UV from approx 320nm upto 380nm with a peak at 350nm, it has special coating that almost completely supresses any IR. In comparison to the two filter combinations [UG11+BG39], the Baader U lets about double the amount of UV through, which allows hand held UV photography albeit at quite high ISO's. This Re-mounted Version is a Baader U filter just remounted in a plain 49mm Mount, please note the new version appears Bluish on the front surface and yellowish on the rear as shown in the photos of the remounted version on a UV Capable 35mm f/3.5 lens here.
 
This UV Capable lens kit with the Baader U filter will combine with any full spectrum camera to produce excellent UV photography. 
 
Options include Sony or Canon Mount.
