The K135 2.5 is a very good lens but its nothing special, personally I think its over rated by the way some people carry on about it.
You have a point here. I use this lens in low light events, and dimlight/short days of winter. Daylight and touring is K135/3.5 or M135/3.5.

There are three lenses I won't miss:

M 1:2.8 28mm - Probably an OK lens and 28 mm is a great FL for me but the F 28 mm is so such better. Plus, manual focusing can be tough with the small DSLR VF and the lack of an 'A' setting makes operation kind of cumbersome. Sold it, didn't look back.

M 1:2.8 35mm - Can't tell exactly why, but somehow I didn't like this lens and the results it gave me. I don't know if it was the FL or the rendering, but I didn't use the lens much. Sold it, didn't look back.

Porst 1:3.5 200mm - This is a cheap, rebranded third-party lens from the 80ties. The lens feels like a Pentax K, but that's just the build quality. IQ-wise this lens is rubbish - soft at all apertures. And I'm not a pixel peeper, so this means really soft... I would sell this lens, but I'm pretty sure I'd get less than 15 for it. So it's not even worth selling.

Zav,
Your copy of the K135/2.5 must be something wrong with it or you have never used it.
I have many other 135mm, but the K135/2.5 still in my keeper's list. and I don't think I let it go if i got 135/2 or 135/1.8...
Oh no it's working fine. And yes I have tried it. It's just totally eclipsed by the Voigtlander 125 f2.5.

That's not fair, you should share with me! Surely you don't need two?
But I have 4 DSLRs and 4& film bodies I can use the lens on, and I have two eyes for focusing

Any lenses that are more trouble than it's worth to sell I either give away or throw away.

Sigma 35-80 f4-5.6 - it's in my garage somewhere, probably needs a clean up.

Pentax FA 70-200 f4-5.6 - also in the garage, condition as per the Sigma. This one comes with free UV filter permenantly attached (as in... It's jammed on there). No front lens cap though its getting use on the DA15


Last used in the heavy snow in NYC in the President's Day storm Feb17th, 2003 - got a bit wet.

Well...
I have old off brand lenses and I test them.
It is one thing to have a lens with FL/aperture/range not suitable to support your needs.
For those condemning a lens as no good inherently, how about some reasonable res images so we can see?

Sure. Here is a picture of a graduation ceremony indoors, using the K200D and the SMC Pentax-F 80-200mm:



And here is another graduation picture, same basic conditions, with the K-5 and the Pentax 18-250mm:



Better equipment means much better pictures are possible. The K-5 and the 18-250mm were ideal for the job; the K200D and the SMC/F 80-200 just didn't cut it.

not an overly fair comparison I think. While I'm no fan of the budget f zooms (or Zooms in general for that matter) the first shot suffers more from motion than the lens. it looks like SR didn't lock and it needed it, and focus is off as well. Not to mention the fact that the k5 is far superior for low light allowing faster shutter speeds
if you'd reversed the lenses you may have had the same results
the first shot the WB is dramatically off as well so if you adjusted it in PP it would have been better

the K5 is so much better than the K200 (same sensor as K10 which I own) that the situations/photos just cant be compared irrespective of the lens on the camera. You might as well compare film emulsions from the 19th century with todays films, and then complain about the lens

I am shocked at how little love there seems to be for the K135/2.5. I think I can make fair comparisons as I also have the M135/3.5, an SMC Tak 135/3.5 and a tele lentar 135/2.8. All of which are actually also very good, but the K135/2.5 is in my opinion the best and sharpest, and also the fastest, which is where I use it most , wide open.

I would agree, if light were no issue at all, then the M135/3.5 is a fine lens, no question. and at about half the weight and size, easier to deal with. BUT when you need speed, and an incredibly bright viewfinder there is nothing that can be a substitute for a truely fast lens

You are basically right - the K-5 gives great ISO flexibility. However, in the first shot, with the F 80-200 lens, the focus was sluggish, not very exact, and the lens couldn't admit enough light to get a usable shutter speed to arrest motion, given the limited ISO range of the K200D. Sure, the lens would perform better attached to the K-5, and the white balance (set at "auto" on both cameras) was way better with the K-5. Another thing - when we got outside of the first graduation, the widest setting was 80mm - that equates to 120mm with the 200D. In order to take small group shots, I was forced to back off quite a way to include the subjects in photos (I could only pack one lens on the excursion). With the 18mm widest setting on the 18-250, I could easily get away with one lens, finding an equivalent of 27mm just fine for group shots outside at a reasonable shooting distance. Way more versatile for the job at hand. Focus on the 18-250 was always quick and right on the money. The 18-250 was just far and away ideal; the F 80-200mm fell short on most counts. You make some good points, but I still find the F 80-200 useless for all practical purposes now that I have a superior all-purpose lens and a much more advanced camera in the K-5.

Not a fair comparison. The camera makes all the difference in this case & the K5 is leagues ahead of the K200 on almost all counts. Put that 18-250 on the K200 and you'd have the same results as your first shot. On an older camera with good light I've found the F80-200 to be a very decent lens.

This might not be the best example, but all I could find at the moment. Taken with the F80-200 on an *istD at 80mm - little or no pp:

Old slow zooms rarely focus well in low light I find-my tamron 28-200 ( equivalent to the pentax mode which I also had for a while)) struggles in low light but does pretty well within it's limitations in daylight stopped down to f8 it actually has given me some good results. It is going to go up for sale though as i don't use it much now
