hi there
i have a vitax, verito and 2 veritars. they are all 8x10 lenses ( 14 & 13.5 " ) but i use them on a 5x7 camera. the second veritar ( 10" - 5x7 lens) that i have for 4x5. the veritar lenses were made in the 1950s, and they were coated modern version of the older verito lens. from what i understand it uses both chromatic and spherical abberation ( or so i have been told ) to create its soft effect when shot wide open, and as the lens is stopped down, as with most soft focus lenses, the image becomes much less soft. i don't want to say completely sharp, because there is still a tinge of softness, but all the same, it is more like an anastigmatic lens when stopped down. the vitax is a petzval design which is what a lot of the 19th century lenses were, before the rapid rectalinaer lenses became popular. it has a curved field and is pretty fast ( f3.8!) and there is a knob on the side that you can turn. the knob moves the rear element to "defocus" the image, so if you stop down you can still soften the image. sometimes i shoot it wide open, when i want that effect, and sometimes i shoot with it stopped down to f8 or even f22 and defocus a little bit. it really gives a nice smooth and creamy look. the vitax, like the verito is in a studio shutter, which works well if you are taking low light portraits, but not very useful if you want to go outside and do enviromental-work. i use 300WS novatron monoblocks with a "medium" chimera and a 42" larson enterprises soffbox. i don't use the strobes, but the modeling lights, and it works really well with these older lenses. the veritars i take outside, since they have working variable speed shutters.
i find veritar portrait lenses on FEEbay from time to time and post a "heads up" when i remember. there aren't many of these lenses around, in good working condition, and they do not sell for thousands, but hundreds of dollars. if you like the cooke lens, one of these early 20th century "classics" might also work well for you.
before i forget, jay tepper always has a huge selection of soft focus/portrait lenses on his website:
http://www.jay-tepper.com . he has a bulletproof return policy ( you don't like it for whatever reason i'll take it back and refund your $$ no questions asked! ) it might be worth checking out what he has, rather than surfing endless hours on FEEbay do get duped by a seller who has no idea his lens is missing a knob, or has a broken shutter or ??? the last i checked, jay had a vitax in a barrel for sale on his site
oh, i almost forgot, there is a guy at
http://www.cameraeccentric.com/ who has a bunch of portrait lenses on his site including a verito lenses in betax shutters ( i think mark wangerin uses a betax mounted verito ) there are also catalog pages on his website where you can read what the folks at wollensak said about their lenses
good luck!
