View Full Version : M42 lenses

Wonder if anyone here use M42 lenses, and wich one is your favourite.
For now, I only have Jena Pentacon 50mm 1.8, ordered some Greens Federal 135mm 2.8 for 12$ but don't know anything about it.
I found this Pentacon quite usable lenses, sharp at wide open, colors are brilliant, but it seems my M42-4/3 adapter is fatter then it shoukd be, as it takes at least 2 stops.
My wishes is Mamiya 135mm 2.8, but can't find any

I think you'll find there are plenty of others playing with old lenses. there are bucket loads around and some are very good. ;)
Your adapter won't make any difference to the exposure but the meter can be fooled by MF lenses into thinking there is more light than there really is - since they're designed for 35mm a lot bounces around the box - especially wide open. Use average or spot metering - or sunny sixteen :)
My favourites are zeiss and Takumar 50/1.4 - at the moment anyway - there are so many!

I find the Pentax Super Takumar prime lenses very good. I haven't had good results with any zooms, all very disappointing.

I've got these:


and this:


The Zeiss 35mm is my current favourite. The 135mm Zeiss has a dodgy aperture cable, which is a shame as it's a nice lens. The Tamron gives me a nice big zoom and the 50mm Pentacon isn't bad either. All free courtesy of my late Great Uncle. I don't know that I'd buy any legacy lenses, but they're nice to have. The e510 viewfinder makes it a bit hard to focus, but it's not impossible - just takes a bit of time!

Last year I had a thing with manual lenses, and bought/borrowed and tested a selection. Some were M42 and I had to hold them on the front of the camera, as I don't have a M42 adapter.. so maybe the conclusions are not quite laboratory standard.

The SMC super TAK (a 55mm f1.8 I think) was a nice lens but slightly flawed wide open. It was great from 2.8 or f4 onwards. The Penacon 50mm f1.8 was horrible wide open but by f5.6 it was actuallly sharper than the Super Tak (!)

I tried an 80mm Jupiter 9 lens. Mine was un-coated. Again, not brilliant wide open, but very sharp at f8

The best old lenses I have used are the Nikon Series E 100mm f2.8 and the Tamron SP 90mm - both of these are very good wide open, however neither are M42 :-)

Nice collection you have there. I just started to build mine. This is my friend collection, he is really crazy about "old" stuff :)

Yap, true, but I use LiveView and 7x or 10x magnification to focus perfectly, yesterday I discovered when watching at 7or10x picture is really sheaky, but then when hold IS button it do perfectly stabilized image for few seconds so it is possible to focus very accurately
