Hello,
Is there any modern lens with shutter that has similar to old lenses RR, Aplanat, petzval picture (not so contrasty, good bokeh)?
Thanks.

If you're using the lens stopped down and working in b/w, there won't be too much difference between a Petzval, aplanat, or rr and a modern lens. Maybe a little bit in contrast due to the coatings, but all will be pretty sharp.
The Petzval will have a look all its own at wider apertures, (curved field, soft corners, maybe some swirl sometimes), and no modern lens will give that look. Rapid Rectilinears and Aplanats (pretty much the same lens) will again look not that different from a modern lens.
The petzval will have its own pronounced bokeh. The RR/Aplanats I'm not so sure about...

Congo makes a soft-focus lens in two focal-lenghts, 150mm and 200 mm.

I bet a small company could make some good money, making modern petzval lenses for a variety of formats (from 35mm, all the way up to big LF cameras). I mean, the petzvals aren't really that precise to make, are they? certainly not as precise as modern lenses, I would guess.
when I get time, I'm going to try and make one for a 35mm camera

Um, Daniel, those old Petzvals were designed and made as carefully as modern lenses are. No one, except perhaps the clowns who make and sell LensBabies, has set out to make a bad lens. Many makers have made lenses to prices, which is very different from making bad lenses.
There are modern -- or relatively modern -- Petzval types, and I'm surprised that none of the people here who want the awful effects they give when abused has mentioned trying them. Projection lenses. The lenses used in overhead projectors have lotsa coverage too, but as I understand it getting the nauseating swirly bokeh requires using a lens on a format it won't cover.
SadChi, the old-timey effect is due to exposure, the emulsion and paper used, exposure again in printing and sometimes even aging of poorly-fixed prints. I have some pre-WWI lenses that shoot just fine on modern films.
Cheers,
Dan
ah, sorry. I thought I ready somewhere that the petzval type lenses were not as critical (for the spacing of the elements) as more modern designs are.
My favorite Petzval so far is a projection lens I don't know how old it is though. The 'real' petzval protrait lenses are too expensive for me.
I've been playing with individual (and double) lens elements when I have free time, this was one of my better results here, I think with the right subject and a blue gel over the lens, it would have an old portrait feel

lens babies tend to smear the image, more than anything else, from the images I've seen. Just like using a single element lens.
