Pentax owners ought to congratulate themselves whenever nice pictures like this appear because it puts new meaning to DIGITAL PHOTOGRAPHY ON THE CHEAP.

Not only do these old lenses get a new lease of life but I can't help feeling users of other brands like C...., N...., O......, S..., etc. are suckered into paying A LOT OF MONEY for new lenses when old lenses like this work just as well and give great results. Newer ain't necessarily better. Obviously we must all keep this a secret if not the secondhand price of Pentax fit lenses will skyrocket. :bsmilie:

Pentax really does SAVE YOU MONEY...:thumbsup:

MF is not as easy as I recalled;p I'll need a better focus screen to get sharper image. Anyone got lobang for a good and "cheap" one?:D

just to nit pick, the 3rd and 5th pic macam got CA and the bokeh a bit messy...

but wot the hell... USD15 bucks for a 132/2.8!

oh wait, does your lens shoot a fully open 2.8 all the time no matter wat your arperture is set to? I've got a cosina that behaves like this.

they are test shots, went around for 10mins to test the lens;)

I can set the aperture by turning the ring. It's not open at 2.8 all the time, as the shutter do become slower as the aperture closes (f/2.8 - f/22):)

BTW anyway to improve the CA issue? I understand old lenses tends to have this problem

Adobe Camera Raw/Photoshop can correct the CA. Stopping down generally reduces lens aberrations.

IMO the Sears which I believe was made by Cosina along with Vivitar 135mm f2.8's are superior to the much praised Pentax-M 135mm f3.5 which I did own and thought very little of. Since then I've acquired both the other brands and have liked the results. I can't comment about whether they are better than the Pentax 135mm f2.8 or the Takumar lenses as I haven't had any experience with those ones.

Nice sharp pics @ f2.8. Often lenses are quite soft at their max aperture setting.

Hi there!
Great pics with cheap and good lens.
Samething for me here.....bought a few M42 mount Aizer and Galaxyprince at very good rate. Guess what? Pics turn out to be quite sharp except that Manual focusing is alittle hard cos mine is not a spilt screen.I use with Raynox 3500 X24 produce super micro pics that really amaze me.......hope u enjoying your toy.
Only thing i dun like is that if it's too bright, you tend to get the white wash effect

Thanks. I noticed the wash out too. I believe the coating then wasn't that good. A auto level on PS will fixed the problem;)

I really love this lens. I don't even need to do much PP. A moderate USM (255% 0.5 0) and up the saturation in raw to +38. Even without any USM, it's good enough to view at 1024:)
