FS: SMC Pentax K 30mm f2.8
I haven't used this little beauty for quite a while, so it's time for it to find a new home. My copy is in Very Good condition optically, mechanically and cosmetically - there is some "silvering" around the aperture ring, the aperture is clean and snappy, the focus movement is smooth, the IQ is exce...

WTB: Pentax K to Q-mount Adapter
Something at the back of my mind says that there are also things you can do with external flash with the Pentax adapter but not with a cheap 3rd party one. It's to do with having a leaf shutter in the adapter. But I'm not sure what they are and might be completely wrong about it! Steve

FS: Several 200mm Prime Lenses
Previous attempts at thinning out the lens collection failed miserably when it comes to 200mm prime lenses - I have more lenses in this focal length than any other by some margin (5 primes and 4 zooms that include it). So I'll have another go - if you're interested please send me a PM. I'll add some...

FS: A couple of SMC Pentax K mount classics
No idea about the 85 but the 135 is a stunner! Also really nice! I did a "Single in..." challenge with this lens a few years back. The results are but be aware there are a lot of "late night safety" shots. Cheers, Kris.

FS: Super Multi Coated Takumar 85mm f1.8
I have an excellent condition Super-Multi-Coated Takumar 85mm f1.8 with original caps and metal hood. Focus is beautifully smooth, aperture is responsive, coatings are very good (some minor marks), optics are clear (some minor dust, as expected for its age). If anyone is interested I can add some...

FS: SMC Pentax M 150mm f3.5 - superb
This is an unusual lens and often overlooked but it really is an M series Gem. There are some negatives of this lens, firstly the fairly long minimum focus distance (1.8m) and there is a tendency to fringe (purple and/or green - depending on lighting conditions) - but where it really does score is i...

Right. Without wishing to derail the thread (it's sold now) ! ..... The OP stated they were unused to old glass - there is no need (or possibility of??) calibrating an old lens. You get what you get. With 'old glass' you can fall into one or two traps. The first is reliance on the image, as sn...

FS Sigma Superwide II 24mm f2.8 - PKAR mount
I suggest adding if it's the manual focus or autofocus version. I will add that the "perfect hood" can be hard to come by so it's a bonus it's included for whoever buys.

Superb lens. Sharp, close focus, fun colours and excellent (in the cinematic sense) flare patterns giving some beautiful effects.

FS: Pancolar 50mm f1.8 - Full Aperture only
I have several copies of this lens and this is my "bargain" copy - it has stiffish focus at the close focus end and the aperture does not close down at all - so if you want one of these purely for full aperture work (which it is known for) or want to take it apart and see if you can restore it to fu...
