hi everyone, i am looking to buy some second hand lens' to add to my k1000 camera. i currently have a pentax M 50mm 1:1.7 that i have found to be quite good. i would like to add a longer lens to my collection. what do you think about the Pentax-M SMC 100mm 2.8 lens. does this lens have a good reputation. does it have any flaws? are there any other lenses that you would recommend. lastly, do you think i would be well advised to stick with pentax lenses?

thanks in advance, simon.

I used to own that lens (also the 28 f2.8m and the 40mm f2.8 pancake lens)and found it to be really nice and compact and well built. It and the 40mm were two of my all time favorites. I use nikon stuff now, but I sometimes miss the MX body and the small lenses. When the MX body wore out, I went with nikon, but I found the pentax lenses to be just fine.

The 100/2.8 usually seems to command a fair bit of money. If you just want a longer lens (rather than the 100/2.8 specifically) and don't want to spend too much money, you might try the M 135/3.5. They are usually quite affordable and I would think image quality would be equal to the 100/2.8, I can't make any criticisms of mine (although it's a K). In some cases it's nice to have a bigger maximum aperature but you're going to pay quite a bit for that for the same image quality.

This lens is a very good lens in the Pentax family, for me one of the best. It's scarce. Really a good lens even on the *ist-ds. I recommand also the 135 f3,5, slightly less sharp but good on digital camera.

Lot's of good info here: http://stans-photography.info/

The SMC-M 100mm f/2.8 is a very nice lens in a small package. Though the SMC-M 135mm f/3.5 is also a very nice lens usually available at a modest price, I like the 100mm better for hand-held work.

M135/3.5 is a sharp lens which costs little on eBay. Another good choice would be an used Tamron SP 90/2.5 1:2 macro.

I own the 135mm f/3.5 and I'm quite happy with it. I might go for an intermediate focal one of these days, between the 50mm and the 135mm - but I can't honestly say that I really need it.

If you want a longer focal, you can also think about getting the Pentax-M 200mm 1:4 - I bought one recently and I must say I'm impressed by the sharpness of the pictures I took with it. A world of difference from my Pentax-F 100-300mm 1:4.5-5.6 zoom that have so often disappointed me...

My advice on the Pentax/not Pentax dilemma: Stay with the Pentax-M lenses. They're small, they're good, they're reasonably priced on the second-hand market. Why look elsewhere?

Hi, Quite late I the day for my reply I guess, however I have a good collection of the Original Pentax Super Takumar, original K mount lenses, M lenses and Pentax A lenses. All of the 60,70's and some eighties built lenses are way better built than the newer counterparts.( I have stripped and cleaned many, I always admire the quality and the fact they do not fall apart.) The original K series 105mm is a gem but bigger, the Pentax M 100mm 2.8 is a beauty and incredibly small, i have never failed to get sharp pictures from it, also wide open the background (bokeh) is excellent. The 200mm F4 is also very good as is the 300mm (rare and expensive) I have also tried various 3rd party lenses and top of my list is Vivitar for zooms(look for a early series one version 1-3 F3.5, 70-210), carl zeiss for primes.
