Just in: a second hand SMC135/2.5K lens

I recently bought the smc 135mm/2.5 and I am happy with it! For example, take this picture. It was taken at F5.6 about closest focus distance possible, 1/15th sec, ISO100 on a Ist*Ds.

It is a pity one needs stop-down metering because Av mode doesn't work! And a pity too, that it has no ED. At least, that's what Photozone.de says. Do we agree? I just think it is a great lens!

There are several brothers of this one running on Ebay now, last week I saw one finishing at approx 90 euros. I feel they are highly under-appreciated!

I agree, and most of the people I know that own one love it. Doesn't bother me that it is a manual lens. So you adjust your aperture by moving a ring on the lens. Big deal. And what the heck is ED?

I have this one, and I love it. It is extremely sharp. Only downside is a bit of purple fringing...it is the king among 135's

Here is the Photozone link for a full test of the 135mm 2.5

Pentax SMC-K 135mm f/2.5 - Photozone Review / Quick Test Report

As we say "nice piece of glass" and works beautifully with my *istD and K10D.

who cares if it doesn't have ED (Extra-low Dispersion) glass. As long as it produces great results, does it matter?

I own a pair of SMC Takumar 135 3.5s. I recently acquired a SMC Takumar 135 2.5 included in a lens package that included 2 other targeted lenses I was looking for, planning to sell the 135, as I couldn't see the benefit of carrying around a bigger heavier lens than my 3.5s for no reason. I changed my mind when I discovered the nice bokeh it produces wide open..... now I use it more than my 3.5s.

actually you can make the lens work in AV. just like a M42 lens. what you need to do is drill a small indent for the camera pin to seat in just before the lens couples with the internal lever. now it's a real stopped down lens..

edit: forgot to say that i've had 2 of the K 135/2.5 takumars that are uncoated. the 1st one i had was the biggest POS i'd ever used. well, maybe better than the sigma 400/5.6 i had. i got another for 18usd and it's sharp as a tack.. must be a prob in QC..

lovely lens

Yes, I also thoroughly recommend this lens.

I picked it up in Tokyo a few weeks ago and just love the smoothness of the bokeh -- see examples below.
It's also quite sharp wide open at f/2.5 and seems to work well with my x1.5 kenko TC - making a 200 f/3.5.

It is a bit heavy heavy (500g) but feels very solid and well put together.
You also have to watch out for flair and avoid shutting into sunlight or there is a loss of contrast.

I'm hoping to use for shooting images of bands and sports in low light where the DA50-200 is not fast enough.

I also recently acquired a Takumar 135 F2.5, and had mixed results with the lens. I often had problems with flare and purple fringing when the angle of the sun was not optimal. However, every once in a while (when the lighting was best) the lens would produce some pretty decent shots.

Funny, all the stages of the 135/2.5 are represented by supporters. I have the
pentax SMC K 135/2.5, others the Takumar 135/2.5 and again others have the tak M42-135/2.5. And we all say it's a "decent" to "very good" lens.

Nice, isn't it?

The biggest difference to watch for is SMC. The Tak 135/2.5 tends to flare. The SMC Tak 135 (M42) doesn't flare as much. The SMC K 135 is less prone to flare as well. Lens coatings do make a huge difference.
