I don't mean to rain on anyone's parade...but really don't like this lens, I have used a M42 variant of this lens on and off for over 5 years, and I just don't like it...I LOVE 135mm lenses on full frame but on digital this lens just loses it. mine is only reasonably sharp at f/4...but I have taken some images that wouldn't have been possible without it's superb control of flare and distortion.

here's an example...

1/250s f/5.6 ISO200 ...second image is a 50% crop

Wow! Those are really impressive! I think it's definitely not just the lens

I have the earlier M42 one, what a gem! But I have yet got anything close to what you posted.

Here are some quick snaps of a boy at the kids garden I took over the Labor Day weekend:

The OP is talking about the Pentax SMC 135mm f2.5 lens from the first K mount generation. It is a 6-6 lens solution supermulticoated, 500g weight and 58mm filter thread. It is identical optically to the m42 lens SMC/Super-Multi-Coated Takumar 135mm f2.5 (referred to as the model II compared to the model I which is another 135/2.5 m42 lens with 5-4 optical solution). This 6-6 lens is considered Pentax 2nd best 135mm.

The lens you refer to is the Takumar (Bayonet) 135mm f2.5 lens, a low budget lens that Pentax made in two versions (f2.5 and f2.8, but there is probably no difference between them) in the early 1980's. This is a 4-4 lens solution, 395g and 52mm filter thread, without SMC coating. It probably have some single coating. It can perform OK with a large lens shade, but it is really a step back to the 1960's and pre-SMC lenses. You can sometimes see sellers trying to make it sound like if they sell the real SMC lens while they actually have the "Takumar (bayonett)". As far as I understand, the SMC Pentax-A 135mm f2.8 has the same poor lens solution (4-4) (but with SMC and A contacts), which explains its bad reputation.
