I came across my old t4 300 f5.5 in a box my mom had with my minolta srt 100 from the very early '70's and was able to mount the tx to it and fully function by taking the flat plate off to bend back the unused slotted peice which interfered with the aperture movement. I like the tx 400mm I have, but never had much luck with the old 300mm (my first LBA purchase) The focus on it is really stiff now, the grease probably dried up.

I didn't know we had a TX mount thread!

I put up a post about my recently aquired Vivitar 28mm/f2.5 TX mount in
Robin's "Vivitar 28mm As FA31 Replacement?" thread here.

casualcollector, you might enjoy that whole thread, and thanks for the interesting T4 page!

I'll read it closely in the near future. I took my recently acquired 28/2.5 to New Orleans back in May. Very happy with the pictures it took but really haven't pushed them past 4X6 either. Here's one of 'em.



Vignetting is the result of a badly chosen lenshood! Definition at the edges seems to hold up well.

I have a Vivitar 135mm f2.5 TX lens. I paid $16.74 for it, including shipping, but the TX to K adapter was $18.24. I did a quick wide-open comparison with my SMC Pentax-K 135mm f2.5, and the TX lens had much less CA. I'm almost afraid to test it fully. It's a similar size to the Pentax, with a tiny slide-out hood. The Pentax has a better aperture, 8 blades, clicks at half-stops and closes to f32. The Vivitar only goes to f16 in full stops with 6 blades.

Hey Bill, that's a pretty freakin' cool picture. Even with the vignetting, which you should have said was deliberate!

The P/ES is a TX mount, a perfect reproduction of the SMC Takumar mount.

The rear of the mounts, unmounted.

Found this old posted, does anyone know that the the P/ES-TX Mount has the A/M Switch which allow the lens to stop down?

Thanks.

Yes - there it is at 4 O'clock, that long slide thing on the mount.

I prefer the P/ES for that reason, but can't get the T4's to mount it reliably. So I use the CS with a wide rubber band to hold the button down when mounted on a K adapter. I don't want to do surgery on these as I have several screw mount cameras I want to use these with.

Anyone has a TX or T4 adapter for PK mount for sale or for trade? Please send me a PM.

I need one: T4 or TX adapter needed.

Nesster, Thank you very much. I had a chance to purchase one yesterday, Vivitar 24mm f2.8 TX with the PE/S mount, but I was not sure about the A/M switch.

I have at least a couple of these lenses, the TX 28mm 2.5 & T4 135mm 2.8. Typical solid quality Tokina-built lenses. I also have an M42 lens with the 'plunger' button and another with the knurled button, the plunger button actually is a handy design for handheld shooting since you can quickly stop down the lens even on a modern body. I think I have one other TX lens but can't recall which it is at the moment - I have a huge collection of lenses... I have a standard M42 mount 'Hanimex' 200mm which is the same lens as the TX, having the tripod mount is a nice thing.
