T mount lens adapters - a question.
The great benefit of sticking with Pentax for me has been the continued use of M42 screw thread lenses. I use them with a small Pentax K ring to M42 thread in both my film and digital SLRs. I've recently acquired for a very small sum a 200mm M42 lens that has a T mount attached to it. As it still has a screw thread, it works perfectly with the usual mount. Is the real purpose of this mount so that you can fit a K mount to it as a permanent fixture, and then use it as you would any other K mount lens?

Re: T mount lens adapters - a question.
M42 thread isn't the same as Tmount M42 is 42x1.0 and Tmount 42x0.75. If you apply some force a Tmount adapter fill fit on a M42 lens. You won't get infinity focus with this combination. Tmount are made for special lenses and other things like microscope and telescope adapters. If your 200mm does focus at infinity it's not M42 but tmount on the lens Toine On 25 June 2010 14:57, Malcolm Smith malcolmsmi...@btinternet.com wrote: The great benefit of sticking with Pentax for me has been the continued use of M42 screw thread lenses.

RE: T mount lens adapters - a question.
Thanks Toine, M42 thread isn't the same as Tmount M42 is 42x1.0 and Tmount 42x0.75. If you apply some force a Tmount adapter fill fit on a M42 lens. You won't get infinity focus with this combination. Tmount are made for special lenses and other things like microscope and telescope adapters. If your 200mm does focus at infinity it's not M42 but tmount on the lens I've not put it up to the camera yet, but just put the adapter ring on the mount and it spun on very easily. I think I will just take this mount off then, as I have no microscope or other special use.

Re: T mount lens adapters - a question.
Yes. You won't get any more automation, (T mounts are basically just
machined metal), but if you're using K mount lenses it's more
convenient. If it's your only K mount lens it will be less so.

RE: T mount lens adapters - a question.
T-mounts have a male thread of 42mm by 0.75mm thead pitch,
M42 lenses have a 42mm by 1.0mm pitch. Don't attempt to
fit a T-mount lens onto a M42 body or M42 adapter directly.
You need to use the correct Tmount adapter with T mount
lenses

If it's your only K mount lens it will be less so. I'm fine on the lack of automation, just trying to save swapping mounts about. I did look at getting a M42 to K mount for each lens, but there is a huge difference in price between the genuine Pentax article and copies - a look on eBay earlier found the genuine item on sale for the better part of £50 from a dealer and £5 copies. Even getting a copy often doubles what I've paid for an M42 thread lens, so it is a serious matter...

Lens adapters
Just a heads-up. A few years ago I had some adapters specially made by a company in the UK (to mount Pentax lenses onto EOS) and I haven't visited the company's web site since. Looking recently, they have merged with another company and seem to have expanded their products. The web site is a lot more user-friendly as well. Might be useful to someone. http://www.srb-griturn.com/ -- Cheers, Cotty ___/\__ || (O) | People, Places, Pastiche ||=|http://www.cottysnaps.com _ -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

Re: lens adapters
Hi, I think an adapter for any type of lens that has a longer register (flange to film) distance by some amount required to machine a thin/thick adapter is possible. Problem with Pentax vs other brands wrt adapters is that most other new - changed mount - brands (EOS, Minolta) use quite shorter register distance than Pentax or Nikon. so it's easy to make adapters for almost any kind of lens to Maxum or Dynax or Eos - their M42 adapters are of bayonet type, just buy one per each M42 lens and voila, unlike the stupid Pentax adapter which you must drill a hole in the lens to do this. See a register table on W.J. Markering's site, if it's still there - any lens with register longer by about 1cm will almost definitely be able to mount with an adapter on a Pentax.

just wondering: What all lens mount types have adapters available to mount them on pentax k bodies. The adapter should be without an optical element preferably. M42 lens is 1.
