How rare is this lens?

For a couple of months now, I've been looking for the last version of the Pentax M42 screwmount 135mm f:2.5 Super-Multi-Coated Takumar with a model number 43812 on the underside of the auto/ manual switch. Most of these lenses being offered are, of course, of the earlier Super variety. Of the Super-Multi-Coated examples I've encountered, my model number queries have not given me the results I've been hoping for. Just curious to know as to just how rare these are, so that I can ascertain approximately how long of a search this might be. Does anyone have a rough ballpark figure as to how long, & how many of these lenses were manufactured? My other qualifications are that it be in excellent (as close to mint as possible) cosmetic, optical, & mechanical condition, which may slow down the process even further.

I have a near-mint copy of the S-M-C Takumar 135 f/2.5 - but it's the 43802 version, not 43812.

I've got one.

I've got one of the 43812 series.

Anything you would like to know about it from a user's perspective?

It took me about 3 months to come across one... like new with hood and both cases. Unfortunately, the box was deteriorated beyond keeping (so I guess you could say I'm still looking and it's been over a year). It's a terrific lens....

I had heard the stories about this lens being special and I was able to snag it off of these forums when one came up for sale. I can only compare it to an M series 135 f3.5 I have, and really that's apples to oranges.... the SMC Tak is much heavier, is a 58mm thread, and has a metal screw on hood. It is brutally sharp anything above 2.8, and at 2.8 is *just* picks up a touch of softness that makes the image pleasing.

The bokeh is buttery smooth and rivals anything I've ever seen on these forums.
The contrast and color rendition is truly wonderful; the reason we got into Pentax glass in the first place.

The action is classic Takumar, smooth lens throw (kinda long, but okay) and aperture ring is a clean solid click. Minimum focus distance is about 7 ft, which is marginal.

The color rendition, the smooth, "painterly" quality of the bokeh coupled with the sharpness of critical focus is what I think makes this a unique lens among Takumar's telephoto primes.

I hope that helps.

It only helps if I can acquire one..... otherwise, you've just successfully frustrated me even more with your enticing description!

P.S. - If any of you guys with a mint example won't let it go for cash, I'd be willing to make a straight trade for my Mint condition SMC K 135mm 2.5 of the same formulation (no original box).

Thanks to the generous, altruistic efforts of Blue on my behalf, this offer has now been rescinded. Blue alerted me to a copy of this lens being offered for sale, which I subsequently purchased..... on to the next conquest!
