Get one while the magic lasts!



I saw this ad on fleabayUK; going by the final paragraph the 135/2.5 has some magical qualities we've missed so far!

Pentax Takumar (Bayonet) Portrait Lens - 1:2.5 135mm – VGC !





Takumar 135 mm f/2.5 lens with 4 element lens construction.

Minimum focusing distance of 120 cm for great portrait photography

Maximum aperture of f/2.5 for bright pictures.

Minimum aperture of f/22 helps freeze motion, capturing fast-moving objects with great clarity.

I suppose if a bug got caught in the middle of the lens....

Oy vay - it takes 3 variable for an exposure - aperture, shutter, ISO.

Pentax Takumar (Bayonet) Portrait Lens - 1:2.5 135mm VGC !
It's not as esteemed as other Asah-Pentax 135's but it's still better than most of the non-Pentax competition. The optics are good; it lacks the SMC coatings but still has good MC coatings. Be sure to use the built-in lens hood.

That CFD (close-focus distance) is true -- it's the closest of all my 135's, which is one reason it's often in my kit. But 120cm is a bit close for portraits -- 150-200cm is better with a 135mm lens.

Flip those around and they're true.

I'd say this was written in a hurry by someone who doesn't check their work.

So Rico, would this in your opinion be better than my Pentacon 135mm f2.8?
I know the SMC Tak 135 f2.5 is THE 135mm to look for, but knowing what would be an upgrade from my Pentacon would be nice.

I don't have the Pentacon; I hear it's great, but I just have no experience with it.

I do have four Asahi-Pentax 135's: S-M-C Tak 135/2.5 (the gold standard), S-M-C Tak 135/3.5, Tak Bayonet 135/2.5, and M135/3.5. All are very good lenses. The Tak Bayonet's shortcoming is the lack of SMC coatings, but careful usage (don't aim into lights!) and a little PP (to boost contrast) fixes that.

For small, sharp, and good light, the M135/3.5 can't be beat. For fast, sharp, and closer focus, the Tak Bayonet is hard to beat. These both also have built-in hoods, a major plus. The S-M-C Tak 135/2.5 does have better optics than the Tak Bayonet, but I find the Bayonet more generally useful. They're different tools for different situations.

I have other 135s by Ricoh, Komine, Enna, Olympus, Jupiter. Some are presets, multi-iris-blade bokeh monsters. For overall IQ I'd rank them as: #1) S-M-C Tak 135/2.5; #2) Jupiter-11 135/4; #3 Enna Tele-Ennalyt and M135/3.5 (tied). But what I use the most in varied situations is the Tak Bayonet. IMHO it's underrated.

Hmmm well I guess I'll hold off until I need something more.. for indoor though, does the bayonette flare much with the normal flourescent/candescent bulbs?
My Pentacon has 6 blade ring.. but there are Pentacon 135mm f2.8's with something like a 15 blade ring (I remember seeing them on fleabay) sure would be nice for bokeh at any F-stop..

I just tried a few test shots directly into incandescents, CFs, LEDs, and halogen lights with the Tak Bayonet. Chimping, I don't see any of the usual flare artifacts. The Tak Bayonet seems to be a K-type lens -- it's certainly built heavier than the M135/3.5. And as I said, it focuses closest of my fifteen 135s. It's just the handiest of my lot. If I want the absolute best, tripodded, I use the S-M-C Tak. If I want to shoot in various conditions, handheld, I use the Bayonet.

The S-M-C Tak and Tak Bayonet 153/2.5's, and the M135/3.5, each have 8 iris blades. The S-M-C Tak 135/3.5 has 6 blades; the Jupiter-11 has 11 blades, the Enna 135/3.5 has 13. One of these days, I'll go hunting for some 135 with 15+ blades, probably in Exakta mount.
