Zoom Lenses
I have the 150-450mm lens and love it, although I do find that, no matter how hard I try, some shots are back focussed whereas others are absolutely spot on.

Zoom Lenses
When I considered a long telephoto there were 2 options. OEM 150-450 and Sigma 50-500. The former was costly but AW level,the later no WR but reasonably priced seeing i picked up a used one. I was also influenced by a few issues of QC on the OEM,it can get stuck at 200mm.More concerning wer...

New lens required
If you want something "cheap" for shooting birds (pun intended) you could try the old FA 80-320 (the later silver model is better than the black one) I got some great shots using mine on APS bodies (you'd have to crop to get the same magnification I did) The lens is terrible at grabbing focus an...

New lens required
If you are looking at landscapes, then manual focus film lenses can be a nice cheap way to get some nice glass. If you need AutoFocus then that's not the way to go, but static scenes for landscapes, especially if on a tripod and taking your time to focus/live view perhaps, and a mid range aperture ...

In the garden with an 85mm F1.4
I I'm going to keep you guessing for a while longer Peter :D It's a very decent lens isn't it. I got mine out a few days ago and the results are excellent but then it went back to the shelf. Just don't use primes.

Samyang 14mm performance
Really nice images. The Sunflower being my favourite. I considered the Samyang when I first got my K1. But with my dodgy eyesight, and it's manual focus. Thought I'd better purchase the 15-30. So I cant compare them never having owned the Samyang. But Looking again at your pics I dont think I can't ...

Repair recommendations for Pentax 300 lens
Hi everyone, I'm having problems with my beloved Pentax 300 lens. The autofocus isn't working v well - (taking ages to find and focus) and also the images have awful chromatic aberration. I'm based near Newcastle-upon-Tyne and wondered if anyone could point me in the right direction to get it lo...

Repair recommendations for Pentax 300 lens
[quote:3496ace15f="bforbes"] What's the basic difference with a DA* lens from any other lens that makes them unable to deal with them? My comment is based on my experience of having to send a manual focus Tamron lens to Alan Marlow to sort it out after AMP had played with it. in relation to the ...

Sigma 12-24mm f 4.4-5.6 EX DG Lens
if it's the Pentax fitting like mine it still has the focus screw drive. I'm not certain that the Pentax version has HSM

Checking out a Pentax SMC-A 35-105mm F3.5 - focus scale oddity
Hello all, long time no see! Merry Christmas to all - impressed to see so many familiar names are still about. I haven't done much with my cameras for a long time, but I'd be grateful for a little advice. A friend has bought a SMC-A 35-105mm F3.5 for her son, who has a K1000 and is getting into...

Checking out a Pentax SMC-A 35-105mm F3.5 - focus scale oddity
i'd return it. Something is not right. It could have been dropped or taken apart and not reassembled properly. There are plenty of other good examples out there.

Checking out a Pentax SMC-A 35-105mm F3.5 - focus scale oddity
Following on from the above, I've just compared the field of view at the short end, which should be 35mm, with that from a DA 35mm AL F2.4, on the same camera, on a tripod, without moving the camera between shots. The short end of the 35-105 is noticeably longer than the 35mm prime, ie the magnif...

Checking out a Pentax SMC-A 35-105mm F3.5 - focus scale oddity
I would suspect it's been taken apart and not put together correctly. Another sample would be more cost effective than repairing this one, probably. I'd send it back as well.

I'd send it back too. That isn't right (and isn't anything like my copy). K.

Pentax Lenses 1965
thanks for sharing Keld - not one I'd seen before, interesting to see the prices at the time too ;) Multiply by about 20 to get todays prices, corrected for UK RPI since 1965. Remember something happened in 1971 in the US. Nixon abandoned the $US link to gold I think, so US inflation might have ...

Pentax K1 K1ii advice
I'm thinking of trading up from my K5iis and K5ii to a K1 or K1ii second hand, or new depending on budget at the time. Before I do I would like some user in the field opinions of the cameras capabilities. 1) In particlular its wildlife capabilties in good and poor light. 2) How good is the auto ...

Pentax K1 K1ii advice
All the below were shot with a K3ii using a sigma 100-300 F4 lens. birds increase in size as you scroll down :D Its certainly possible to get decent bird in flight images, the larger the bird the better / easier it is, and you'll probably not get as many keepers as a Canikon shooter, and your ove...

Pentax K1 K1ii advice
I also agree with Mike, although I'd say skill rather than luck :D Once the technique is obtained, mastering takes time and patience as well as plenty of lost images, its transferable across all Pentax models as well as other manufacturers, and I agree head on shots are more difficult, not imposs...

Dust particles inside lens
I have had my 150-450mm since day one of release and to be honest I have never bothered to look and see if there is any dust present (same with my 15-30mm/24-70mm/70-200mm) as it's not going to make any difference to the output and it would also cause me to continually worry about it. I'm pretty ...
