I'm thinking of asking in the Canon forums, but I know gh2 users like to use old manual lens so that's why I'm asking here. Applications are gonna be for weddings.

That's hard to answer Victor (especially since I don't do weddings) IMO, I would look at 50mm for tighter shots, I love my Nikkor 55mm 2.8 but for something that needs to work in lower light, either my Pentax G 50mm 1.7 or Canon 50mm 1.4.

My preference would be the Pentax because it's nearly as sharp and handles better.

For wider shots....hands down, Nikkor 24mm 2.8.

don I'm looking for a 135 only

I just reread it Victor. Sorry, it's been a long night.
I'll go to bed now.

Leica Elmarit-R 135 (debatable). There are a number of good 135/2.8s to be had.

The Canon EF 135/2L is a solid lens as well

The vintage Canon FD glass works well and is a relative bargain.

Canon FD 135mm f2.0, FD 135mm f2.8 & 135mm f3.5 (http://www.mir.com.my/rb/photography/companies/canon/fdresources/fdlenses/135mm.htm)

135mm F/2.5 is a fun cheap lens. Not the greatest, but really cheap. I haven't used mine in over a year, I need to sell it along with my fisheye, but I've been too lazy.

For wedding work it just seemed so much easier to buy a videocamera, which I eventually did. Best decision I ever made.

Yeah, I want a camcorder and then DSLR for beauty shot. Takumar 135 f2.5 right?

is there a difference between takumar and super takumar?

Mine is a Canon lens Victor.

I have a Yashica/Contax 135/2.8 - I get very nice results, although it's not a lens length I use very often. I think it cost me £50 on ebay.

Ben.

I've got the Canon FD 135 f2 - more than happy with it.
Sharp and fast.
