Sigma HSM AF
After much soul searching and good advice from Penatx forum members I am about to take the plunge and buy a long Sigma lens. Before I do can anyone confirm if the Sigma 150-500mm f5-6.3 DG OS HSM lens is fully comptable with a K7. A forum search suggests that DSLR's after the K100 will work OK but I...

Sigma HSM AF
Slightly off tack but just posted above a problem I'm having with mine. On my K-r , AF is fine for reasonably close objects (say up to about 25-30m) but after that it is very hit or miss, making a clicking noise and going back and forth either side. This seems to happen in reasonably good light and ...

The cheap 2.4 35mm... or spend elsewhere?
Hello Have a little bit of cash to play with and been planning to get another prime after selling the old 50mm. The new pentax 35mm sounds good with the added bonus of auto focus over the old lenses I have owned. Least means the other half will use it for indoor shots of the little one. Am I ...

The cheap 2.4 35mm... or spend elsewhere?
Got a step up ring + rubber hood of another lens so think this will be enough outside. Will look for a better hood at somepoint. My old cheap filter will keep the little ones sticky fingers away! I am yet to be blown away by the lens compared to the kit, but I am getting usable shots in low light...

DA 16-45mm Edge Sharpness
Now I know I have asked about getting a replacement for this lens, but recently the monies reserved for a replacement went to to studio flash units that I needed more. So, now I have a little time to consider a replacement for this lens. Why? well today I took some shots for work with the aforme...

Asahi Photo or Johnsons-Photopia?
I have a DA 17-70 which back focuses more than the K-5 adjustment allows. The repair/adjustment options available to me seem to be: - Take it to Asahi Photo (they're quite close to me), who have quoted me "about £60", although they can't tell for certain if it can be fixed until they get it op...

Asahi Photo or Johnsons-Photopia?
Quick update on this... I took the 17-70 to Asahi, and sadly, the chap said there was nothing he could do with it. So Johnson's it is - can someone confirm that the PUP discount applies to repairs sent in via them? Turns out that Asahi-Photo is a little workshop at the back of a model shop :)

Pentax 14mm
I really like my DA14. It is sharp and colourful with great close focus capability. It is quite a big lens so if you want compact then the DA15 would be better I suppose. Has slight 'moustache' distortion which can't be edited but doesn't really show. Pete not so heavy it can't be used with one ...

Talking to the converted
I was lucky enough to pick up a Sigma 70-200 2.8 EX APO from a forum member here and need some advice. I have picked up on a few threads re sigma converters and have a few questions. Is there a noticeable difference between the 1.4 and2X converter? As the converters are "DG", will they actually i...

Talking to the converted
I have the same lens plus 1.4x and 2x DG converters Is there a noticeable difference between the 1.4 and2X converter? Yes, with the 1.4x you get very little quality loss .. the 2x is really only for emergencies. As the converters are "DG", will they actually improve results for this non DG len...

tips on the FA31mm??
Have to say John's words does put everything into very understandable context but everyone's opinions have been very useful! Think the 31Ltd will live on the camera for a while now so I will get a chance to really use it! I have done that with the 10-17mm fisheye and the 18-250 zoom (voluntarily or ...

FA35 'vs' DA40 Ltd
I have the FA35 and love it for it's quality & sharpness. At first I did a lot with the DOF effects that f2 allows but less so now although it's nice to know I have that possibility. At the weekend we went to a local camera firms 'show' as a Pentax stand / rep was there & for the first time saw ...

If you could only keep one....
My SMC Takumar 135mm F3.5, a humble little lens, but boy is it good! I love the challenge of manual operation with the lens and have had some spectacular results - I don't know if I'm lucky to own a particularly good copy but it's fab. Close second would be my 55-300mm and my Pentax-M 28mm F3.5, a...

If you could only keep one....
As I mainly do wildlife and macro but also anything that looks good it would have to be the DAL 55-300mm and maybe sneak the Raynox -150 in my pocket which it works great with. That's everything covered although I might have to move back a few miles for the landscapes ;-) Dave

What would you choose?
With the IQ of the Sigma 50-150 you could crop it to the FoV of the 18-250 (at 250) and still have better IQ than the 18-250 ! However I'm not sure I'd want to take it backpacking even though it never leaves my side (work or play) ! Superb lens. IMHO though I'd take the 15 and the 18-250 for a mu...

What would you choose?
Unfortunately my financial situation only allows me to own both the 21mm/15mm and 50-150mm or a DA* 50-135mm if I sell my 31mm and the superzoom! Are you sure you could not afford to slot in something like a F35-70mm or FA28-70mm f4? Both available for well under 50 quid. I just got back from holida...

Pentax Lens System choices: 21 limited 43 limited 100 macro
I've recently moved over from a Leica M based system to the K5. Hopefully I'll talk about the K5 in another post, but I thought I'd give my experiences of the lens system too. I was used to using primes, and specifically a wide angle/standard/telephoto combination with the Leica so I thought I'd...
