One of the guys on PentaxForums who's used most of the older lenses is of the opinion that the A70-210 is the best in that range. I have both the M75-150 (which gets very good reviews) and the M80-200. Brief testing suggested the 80-200 suffered slightly less CA on the K-1 - I prefer the longer reach anyway. For something like an A or P series camera, the 'A' setting is a big help. The 75-150 is a bit more compact.

In diameter it's quite broad but compact in length and has a zoom lock switch to stop it creeping when carrying it.

An option is the Tarmron SP 24-135 - xx-80 or xx-105 zooms aren't really long enough to be one lens to rule them all for travel purposes for me. I'm only really interested in 24-50 and then 135+ (my K-1 minimal travel kit is an FA20-35, FA43 & M150).

The PZ 28-105 was always considered better than the 28-80 (which is better than the PF reviews state). The weak point is the PA/S switch on the barrel which always break on PZ lenses - but the basic PZ functionality still works on DSLRs.

I'm about to put my PZ 28-105 up for sale...

These have been withdrawn from sale while I re-asses things, sorry.

Hi All, A change in my glasses prescription means I'm finding it harder to manually focus and it's time to start selling off some of my manual focus lenses. Prices include RMSD to the UK (outside the UK is now too complicated).

SMC Pentax 35mm f/3.5: £120: Good condition, slight dust, no fungus and snappy aperture.

SMC Pentax 50mm f/1.4: £85: Good condition, slight dust, no fungus and snappy aperture, generic push on front cap.

SMC Pentax 135mm f/2.5: £130 Includes genuine hood. Good condition, slight dust, no fungus and snappy aperture.

Thanks for looking.

Hi All,

I'm tentatively looking to sell my second 6x7 MLU (which has some issues - see below), along with a meter prism and some lenses. Trying to set a fair price for a slightly wonky 6x7 (given repair options may be limited) is a bit difficult. If anybody is interested please let me know. Anybody interested in the camera would have first dibs on the lenses, I won't sell them individually until the camera is sold.

6x7 MLU: This is heavily brassed on the right hand side and generally works (I will organise some photos). It comes with an 'Asahi Pentax' branded meter prism and a 3rd party 3D printed right hand grip.

Issues:
- It won't open-aperture meter at all, there's no damage to the meter chain so something else is wrong. I've tried a different meter prism with the same result. When the meter is 'Off', the needle sits at the top of the range (unlike my other prism). Stop down metering works fine, and with the Auto/Man switch on the lenses not too awkward to do.
- I have a vague impression that when held in portrait format (right-hand up), the mirror hesitates for a fraction of a second before the exposure - it's not an obvious delay, it's just doesn't quite feel as responsive as my 67.

Lenses: These lenses are duplicated by others or otherwise no longer needed:
- 55mm f/4 (latest version) in very good condition - this is a fabulous 28mm equivalent.

- 75mm Shift - this is a 35mm equivalent, it's in very good condition and comes with its original Pentax case (tatty). It doesn't have an auto-disaphram and I'm not able to get it to stop-down meter on the 6x7 MLU or 67 (not sure if it's expected too but there's no apparent damage to the mount).

- 200mm f/4 - this is the 'middle version' in good condition. It's a great lens only let down a little by it's fairly long minimum focus distance.

- I might have extension tubes 1 & 2 somewhere also.

If anybody is interested, please let me know, happy to discuss the issues in more detail if needed.

John.

On the 645D/Z the large eyecup attaches to the small eyecup (the part I linked above), it doesn't have its own thread. I assume the 645 is similar if not the same.

Normally I wouldn't comment on an auction, however, I'd suggest re-wording this part of the listing: 'The k-1 is a full frame 36 megapixel camera with pixel-shift functionality that can increase image size by four' - it can't.
