Whatever the reason I do enjoy it, and actually these are the real reasons why I do it, It gives what I do a fresh impetus, its stimulating, it makes me think about what I'm doing and stops any sense of coasting and going through the motions. Even though photography is my job, I don't want it to feel like that. I'm an enthusiast, its my hobby and my passion and using these lenses constantly refreshes that. I spend enough time in the tedious process of editing, captioning, keyworking and uploading, so if I can't enjoy myself when I'm out taking photographs then I might as well go and get a "real job".
VOIGTLANDER 12mm f/5.6 ULTRA WIDE HELIAR
I've been considering one of these for some time. I've been put off for two reasons. Firstly they are very expensive and Secondly the problem with the magenta cast and vignetting on the Sony NEX-7, which is the camera I would use it on most.
The first was taken care of by Robert White selling some of the older screw mount versions at a slightly cheaper price. Still not inexpensive, but less than the new versions. So I bought one and fitted a screw > m-mount adapter I had lying around.
The second "problem" was taken care of by two things. It isn't actually as bad as its made out to be and its easily fixable. I read somewhere, I think on Luminous Landscape, that the Voigtlander 12mm is not as bad as the 15mm, and it certainly seems that way. Yes there is a magenta cast at the sides of the image plus some vignetting. However as you can see from the example below of the shot at the top of the page, its perfectly possible to get a "normal image" from the lens.
In Photoshop I open up selective colour. I select blue and remove all the magenta. This gives a green / cyan sky. However it is now a pretty even colour. I then open up selective colour again, select cyan and add magenta to restore the colour. This actually takes me an instant, as I have the process set up as an action, so I just press a function button and its done. This stops all that messing about creating profiles and converting the raw files using Cornerfix.
VOIGTLANDER 90mm f/3.5 APO LANTHAR
So, a very enjoyable afternoons shooting and I am planning to use the NEX-7 and 5n as manual focus cameras exclusively. It's easy with the focus peaking, gives better results and is much more enjoyable, and those strike me as pretty good reasons to work with them in that way.
