I need a reference place to store my feedback on various lenses I have tried for UV photography.
I do not have access to any kind of spectrum analysis so this is my real world playing about.

My setup: Canon EOS 600D (Canon EOS REBEL T3i) with full spectrum modification by Ehab Eassa  (Eassa on eBay) Using a Quartz Spectrosil replacement for the removed IR/UV block filter.

Microlenses still in place. (Removing these renders the camera incapable of colour but improves contrast. It turns it into a UV only camera, not full spectrum).

Sensor cleaning mechanism removed.

Pros of this camera : Appears that the Sensor is UV sensitive and the fold out display with Live view is excellent.
Cons of this camera : cheap and nasty plastic design unlike the more professional series. (also a pro, as you can modify and obtain the camera cheaply).

Canon Lenses

Canon EF L series 24-70 mm with step up/down rings and a BaaderU filter (1.25″) on the end – needs a high ISO and long exposure time. Not suitable for anything that moves. Not enough light for Autofocus to work. Nice images but frustrating to use. Click through to the photos for more details.

Canon L with Baader U (UV)

Baader U on Standard Lens

 

Canon EF 50,, 1.8 mm lens with step down rings and Baader U filter. ISO 800 and 1/13 sec exposure works well. Might be good for Video. Autofocus in UV range works. Native EF mount is a bonus. Cheap nifty 50 lens. Well worth playing with as it causes the least frustration and messing about. It is cheap so within reach of most people. Works well showing sunscreen response, not as good showing flower patterns. I need to do a video with this one.

Minolta E.Rokkor 50mm f4.5 Enlarging Lenses, M39 Mount – No idea just yet. Just ordered this and will know soon.

Minolta E.Rokkor 75mm f4.5 Enlarging Lenses, M39 Mount – No idea just yet. Just ordered this and will know soon.

Helios
Helios 44-2 2/58 Russian USSR lens M42  Zenit 1979 – preset. This lens is a preset lens which gives it two aperture rings. An Aperture lock ring and a smooth (no click) manual aperture ring. Great for Video. Yet to try UV.

Nikon EL Nikkor

Nikon 1:4 50mm El-Nikkor Enlarger Lens f=50 – works ok on UV. Need to be close to the subject. Need a M39 Screw Mount to EF adaptor and I use a Bellows to get focus. Step up/down rings to fit Baader U. 75mm is better.
Nikon EL-Nikkor 75mm f/4 Enlarging Lens – works ok on UV. Need to be close to the subject. Need a M39 Screw Mount to EF adaptor and I use a Bellows to get focus. Step up/down rings to fit Baader U. Most of my UV photos in the flickr set that involve flowers were done with this lens.

NIKON EL-NIKKOR 80MM 5.6 PROFESSIONAL ENLARGER LENS – works ok on UV. Need to be close to the subject. Need a M39 Screw Mount to EF adaptor and I use a Bellows to get focus. Step up/down rings to fit Baader U. 75 mm is better.

Optomax (Pentax)

Optomax 35mm f/3.5 – You have to stand too far from the subject, the UV response is bad and focus is hard to achieve. It is a wider lens than my EL Nikkor so it does have it’s place.
