I confess. I love collecting 35mm F3.5 lenses – I must have over 30 in my collection now. I mainly buy them to see if they are useful for UV-imaging. And if they are, then I add them onto my collection.
There is sound reason for doing this, which are:
1) The lenses which are useable for UV imaging are rare and will be valuable to the UV-imaging enthusiast as a tool (and as an investment)
2) You can’t get much better than these lenses without forking out for the Coastal Optics 60mm/105mm or UV Nikkor 105mm (each bearing a 4-digit price tag, and the Coastal Optic prices keep going up).
3) These are old lenses, which are no longer in production i.e. limited stock out there
4) With time, many of these lenses will succumb to mould, scratches, haze or DIY-madness, and hence there will be even less useable lenses available with each passing year
5) We all know that the rare lenses, with desirable properties become more valuable as the demand for it increases, and they may no longer be as affordable later on (just look at the Noflexar 35mm F3.5 lens)
6) Always good to have multiple copies as a back-up (just in case)
7) It is good to have different setups for different uses e.g. for travelling, a compact and lighter system may be better (I have a compact system to show later)
Anyway, here are some of the 35mm F3.5 lenses I own.
Conventional M42 lenses:
Kuribayashi 35mm F3.5 (discovered by Steve Smeed and confirmed by Dr Klaus Schmitt) + their look-alikes
See link here on Dr Schmitt’s blog regarding the Kuribayashi: http://photographyoftheinvisibleworld.blogspot.co.uk/2012/07/kuribayashi-f3535mm-lens-for-reflected.html
As you can see all the above lenses have a strong family resemblance (optically anyway).
