I only have the M85 f/2 and the M50 f/1.7, but I love them both.

The M85 at f/2:




And the M50, probably at f/2.8. That's a basic-training haircut, not some skinhead thing.

Anybody try the 50mm f1.7 with a TC? I'm thinking maybe that would be cheaper than buying a separate lens for a bit more tele length. I could also use it on my third party 400mm and get crazy far. XD

Pentax prime lens vs zoom lens at same f stop

Hi. I am seriously thinking of getting an old Takumar 135mm f/2.5 lens but am not sure if it is a good move since I already own a modern Tamron 18-200mm lens. Can someone tell me if there is a noticeable difference in IQ between the two lenses if the latter is set at 135mm, assuming that available lighting is adequate? Should the former, being a prime lens, be better? Comments and suggestions will be much appreciated. Thanks and regards.

In General Primes are always better than super zooms for IQ. some exceptions of course exist
There are a couple of Tak 135 2.5. the SMC tak M42 (a true takumar) is well regarded and should in all cases beat the tamron on iq (and of course will shoot at a much faster aperture
reviews of the 3 variants of this one
https://www.pentaxforums.com/lensreviews/Super-Multi-Coated-TAKUMAR-Super-Tak...35mm-F2.5.html

the non SMC Takumar bayonett (ie k mount) is not as good. that being said it will be faster than the tamron by at least 1 stop. and will have better OOF area just by vitue of being faster
reviews
https://www.pentaxforums.com/lensreviews/Pentax-Takumar-135mm-F2.5-Bayonet-Lens.html

The K 135 2.5 is a stellar (but getting pricey) lens same optical formula as the last verion of the SMC tak but K mount rather than m42
https://www.pentaxforums.com/lensreviews/Pentax-Takumar-135mm-F2.5-Bayonet-Lens.html

the K was replaced by the A* 135 1.8 - very expensive but top notch (hard to find as well)
https://www.pentaxforums.com/lensreviews/SMC-Pentax-A-Star-135mm-F1.8-Lens.html

the only one that won't necessarily be better than the tamron is the non SMC takumar bayonet - but if you need speed at that length it is a good value

Hi Eddie. Thanks a lot for taking the time to give me this detailed reply. No, I don't really need speed since my K5 takes care of that (ie, ISO). There's a lot of the non-SMC Takumar 135mm on THAT site, but they are not really cheap. Thanks again and best regards.

Iso can take care of speed but if you don't have a big enough aperture then you might not be able to get the OOF (or bokeh) that you want for shots. having a fast lens opens up an entirely different area of photography. Your Tamron lens is probably f5.6 at 135mm. The Takumar will be 2+ stops bigger and that is a huge difference in OOF. This is one of the knocks against the otherwise excellent DA40 when compared to the fast fifties. If I'm taking portraits (torso/body) then 1+ stop makes a huge difference. I always take my M/A 50f1.7 if there's a chance that I'll be taking portraits. The primes will also have better IQ.

You could get a M135f3.5 ($50ish) or M100f2.8 ($100ish) instead. It's not quite as fast but still about 1.5 stops faster than your Tamron. Here is a shot with my M135f3.5 wide open (reposted).

I think the answer will hinge on what you personally consider "better IQ". Would a bayonet mount Takumar 135 be better than your 18-200 Tamron zoom at 135 with both using the same aperture, probably a tossup

As far as zooms v. primes, I have been slowly leaning towards zooms. I feel I have 3 dependable zooms, the Pentax A 35-105, Pentax M 75-150 and Pentax F 70-210, I would have no problem using any of these over primes. Although I think they are all superbly sharp, at this point I am no longer looking just for the sharpest possible lens I can use, but more about colors, contrast and "overall" sharpness it can produce. Since Out Of Focus/Bokeh is not only controlled by aperture used but also determined on distance/magnification of subject to camera, using a zoom should not hinder too much and in some cases will help.

Pentax M 75-150 most likely been posted but decent examples









*With that said, if I know I will need a 135mm prime for something (really really) special, I will reach for that lens and use it everytime...
