Alvin wanted to know how crisp the 135mm 2.5 was so I took some sample shots today and here is what I have to show off:







I hope these images help people and I'm still getting used to this lens, it's super touchy with the focus so probably a great portrait lens, not so much for nature photography in my opinion.

that is a sharp lens. I don't think my SMC M 135 3.5 is as sharp as your 2.5

thanks for posting

Thanks for keeping me in mind, Codiac!

I agree with Randy. I just got the 3.5 and it's good but that's a big difference. Were these shot wide open?

I haven't used my dad's M135 as often. But this recent debate shall inspire me to use it a bit more. That 2.8 on the Rikenon is helluva tempting though.

Haha stop trying to giving Alvin, buyers remorse. :P jkjk. Don't worry, I'll show you some M135/3.5. (Soon. Gotta get some assignments finished.)

[codiac2600]

Yes those are all taken wide open, I'll take some more later today when the darkness breaks out here at different stops if nayone is interested.

Pete - who said I had any remorse? I may just hand someone my 135/3.5if the price is right for the 2.5 - The extra aperture stop will come in handy this summer. Then I might just grant you that wish and you'll have your second 3.5!

Thanks, Codiac! I wonder - What's the dimensions of the 2.5 lens? The 3.5 was a lot smaller than I thought it would be (about 2/3's the size of my Sears lens).

Gosh... I actually didn't bring my bag with me today and to give u a rough guestimate it weighs like 90 million pounds and is nineteen feet long. It's about 5 pounds (seriously, it's a heavy piece of steel and glass) and it's just shy of the length of a tamron 75-300mm. Hope that helps, but I'll give you exact info when I get back to the house later tonight.

I'm not sure what does mean nature photography but I tried it last Sunday and personally like what it did.





and here 4 shots stiched together (black and white)

I was mostly talking about moving creatures like birds or squirrels since it's such a toucy lens and the dof is very punchy at times making a decent crisp focus on the fly very tricky. Nice pics by the way! Oh my mom is from Warsaw or maybe it's a small town outside of warsaw, i'll have to ask her again.

which model 2.5 are we talking about. i know of at least 2.

[Piotr]

I'm talking about Pentax smc 135mm f/2.5 with 58mm diameter.

I didn`t know this lens , when does it date from ?

I saw a few days ago in a shop a secondhand 135mmf/2.8 (dates from 1991) for 300 euro , is this a good deal ?

Do they still make these and at what price ?

thanks piotr,
i had the non-smc version, 52mm, for awhile. i did not need another paperweight so i sold it.

That's a big lens! Nothing like the couple hundred grams and small dimensions of this M135/3.5.
