versions of 135mm/F2.5

Are there multiple versions of the 135mm/F2.5, K-mount lens? I want to buy a 135mm lens with an F/2.8 or F/2.5 aperture. I would get the auto-focus FA 135mm, but its a little expensive. Mostly, I want to experiment with bokeh. For bokeh rendering, I currently have the 70/F2.4, and the 55-300mm. I have also considered the 77mm/F1.8 but it is even more expensive. So, are there any versions of the manual focus 135mm lens that I should avoid or aspire towards buying?

As far as I remember, the 135mm K mount lenses are Takumar Bayonet mounts. No SMC, so they'll be prone to flaring and losing contrast. Check out the original Super Tak 135mm f/2.5 and f/3.5. If you don't already have one, you'll need the adapter. I use the 135mm f/3.5 all the time-- Bokeh is pretty good, and colors are beautiful. Past f/4 it's really sharp all over. I've heard the same about the f/2.5 model, too, and that it is even better. Plus you get about a stop faster and better bokeh. You should be able to find one with the original hood and case for $100-$120 which is a pretty good bargain. The f/3.5 model is a steal, too-- $40-$60.

I've heard fantastic things about some of the Russian lenses for bokeh, too, maybe someone will chime in on which ones.

The 135mm f2.5 MC (K) is superb--and for its quality is a bargain (like the 50mm f1.7 M) . The 135mm f2.5 Takumar (K) is not SMC and is not highly thought of--but can be gotten cheap. I have the former lens.

So, the "A" version of the 135mm ought to have SMC, so its a good lens? How can one tell the difference between the 135 F/2.5 MC(K) and the 135mm F/2.5 Takumar(K)? I guess look for the "SMC" designation?
Would this be a good version? https://www.pentaxforums.com/forums/24-photographic-equipment-sale/239592-sal...rice-drop.html

The takumar bayonet version look like a toy with aperture numbers in different colors.

Takumar bayonet have text outside the barrel. The K135/2.5 has the text around the front glass.

I own the much-maligned 135 f2.5 Takumar bayonet. While it is not a world-beater it is quite good. I use it regularly on my LX and ME Super; since it lacks the "A" it is a PITA on my K-5. Folks have complained of flare with this lens, but that's why one uses a lens hood, isn't it? And by looking through the lens you can see how much flare there is. The Takumar has an entirely adequate built-in lens hood which needs only to be pulled out to deploy. And the price is often right.

I concur. Use the hood, don't shoot into the sun etc and it is a more than adequate performer. There is probably lots of sample variation out there now with this lens, given its age, but I'm happy with my copy.

I also have an M 135 3.5 and the Takumar performs about the same, but with nicer bokeh.

I also have a copy of the Takumar Bayonet 135, like previously stated, just use the built-in hood and don't shoot into the sun. It is surprising how good it is and the low prices just make it better.

I have the SMC K 2.5 / 135 and has been my indoor concert lens. This is just a solid well built tool, crisp and clean after all these years.

The SMC M 135 f3.5 is perfectly usable wide open and is physically really small and light. It is one of my favourite lenses. They often sell for little more than the price of postage on eBay.

The A 135 f2.8 is SMC and is an excellent lens - I've owned 3 over the years and been impressed with all of them! It's the one I would choose (unless you can find an A* f1.8 )

The best of the 135s is probably the A* f/1.8 followed by the K 135 f/2.5
Pentax Telephoto Prime Lenses

The problem with the K version is that a) whilst not rare it's not terribly common and b) it has a 1.5 minimum focus distance.

However it has wonderfully FA ltd like image quality and is pretty damn sharp all these years on. It fringes a lot but stopped down, or PP'd well, this isn't an issue.
