These are so beautiful. However, the lens is a challenge to use. One does need to have a control of the weirdness it can deliver.







In the very first picture, it iseems tack sharp in the twigs, (but it isn't), and then this acts as the grounding and reference for the important "spacey" LSD background.

What are your ideas for where you can get the most out of this interesting optic?

I am amazed by the beauty and boldness you have drawn with this optic!

So what is the difference between the three examples you have? Do you believe there are more out there to buy?

Well, indeed, this lens is a very special beast: This SHROOM/LSD-effect I used happens when slightly defocussed. Certabily not a lens for every day, but used at the right moment, no other I know could produce such images!!

Nope, there will be no others: in 2012 I was able to acquire three remaining prototypes of those lenses, made 1992, which came from company of the inventor, Richard Nye and his company, Nye Optical of La Mesa CA, when his son liquidated the remains after the passing of his father. I was very excited to find such lenses, but they turned out to be a bit tricky to convert and adapt to digital cameras. Now with mirrorless ones, it looked rather promising... and I finally succeeded this year.

I got one f1.1/90mm Lyman Apha II lenses and two f2.8/200mm Lyman Alpha I lenses, of which I recently sold one. The f2.8/200mm is much more "tamed" than that "wild horse" f1.1/90mm...

The full album of images for the f1.1/90mm is here: https://www.flickr.com/photos/kds315...57702692038345

Btw. all those lesnes were once made to record deep UV images, hence their "Lyman Alpha" name, which denotes the Hydrogen 121nm spectral line.

Here focused and defocused in comparison:

What is the nearest equivalent lens, albeit not with UV special line prowess!

A mirror (CAT = catadioptric) lens, but all I know (I have a few) do not show such behaviour...

Its sister lens, I have posted about here: http://www.openphotographyforums.com...961#post187961 shows a behaviour other CAT lenses also show...

So THAT can be had for little money... I would look for a 5.6/300mm on ebay

I have had vertigo and nearly suffered a relapse. Lovely and what unusual effects from the lens.

Wow. Love the abstract images. Can't say that I've ever seen anything like that just from a lens. Very artistic, unusual, and cool.
