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 a pair of Chinese made ZWB2 and QB39 Filters. 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 filter set included in this kit is particularly useful as the pair can be used together to photograph UV only. Individually the QB39 can be used on a full spectrum camera to give normal colour in daylight. The ZWB2 however will pass mostly IR but with some Blue and UV and so gives a grey foliage with blue sky effect.
 
The ZWB2+QB39 pair are fine for UV photography if using very high camera iso, but they are not as efficient as the Baader U UV Pass filter which is approx 1-2 stops more efficient. 
Please Note, the QB39 filter is particularly prone to surface oxidisation and as such has a limited shelf life. Once all the stock I have is exhausted and the clean ones are sold, I will not stock them and they will only be available to special order.
 
Options include Sony or Canon Mount.
