Pentax K10D revived - are early silver AF lenses OK?
The 80-320 has a very long extending barrel and has a reputation for developing unfixable wobble when extended - mine certainly did (so badly I would not have dared to sell it on). Also, was not very impressed with the image on my GX10 (K10D). Replaced by the 55-300, which is sharp but rather sl...

Takumar 135/3.5 preset, slight play in mount
Hi folks, I have a Takumar 135/3.5 Preset (M42, all black), and it has developed a slight play in the mount section (tube) that telescopes under the focusing barrel. I have removed the back retaining ring, and see two more concentric retaining rings around the back lenses, but they seem tight. Th...

Help with choice of convertor.
The Pentax HD 1.4 is probably the best match for the DA*300! Optically it's one of the best I've used. It carries through the SDM focus (and will do screw drive on other lenses). It matches the DA* in WR (so assuming your DSLR is WR you have a complete outdoor weather solution). But it's a bit on...

Pentax 55-300mm with Tamron 1.4xPz MC4 very pleased
I bought the 55-300mm HD DA lens a while ago and was immediately impressed by it, for such a reasonably priced lens it's optical performance exceeded my expectations. A few weeks back I bought the Tamron 1.4x Pz MC from Daronl on this forum. This afternoon is the first time I've properly tried this ...

150-450mm lens 35mm equivalent shown as 230-690mm
Not for sure, but maybe the focal length quoted is just an average, as focus distance can also change it as well as zooming. Zoom lenses are very complex things.

Just purchased a k3 II and need advice on specific lens
I am new to digital photography. Used to do a lot of work back in the film days n the early 80's and do know my way around a camera and lighting effects as I took product photos for my small business as I always thought it was better to do something yourself and learn something new as opposed to pay...

Thanks Mille19 and LennyBloke, I am leaning toward the macro for the reason's you stated about close focus. I will want to get in close to show the details in some of our other products like scarves and beanie hats. I must say I was a little skeptical about the quality of the 50mm. Online revi...

SRS Bank Holiday Lens and Camera Offers
Apologies to you both. As soon as I did the deal with Pentax, I posted on here and they will be going back up in price on Tuesday. Special offers can be difficult in this situation which is why I gave as much notice as possible on here.

Pentax FA 70-200 f2.8 release date pushed until next year
The Pentax FA 70-200mm f2.8 now has a pushed back release date in late February of next year - at the earliest. Unofficially reading a bit further into it (and from a few unnamed sources) the Pentax full-frame camera body will also not be released this year

Pentax FA 70-200 f2.8 release date pushed until next year
Agreed with the above...better not to release a lens (or camera) that is not fully rested and 100% (well 99.99% anyway) fault free, than have a whole load of early problems (remember sensor stains, oil from on sensor(Nikon), white orbs (Fuji)) Not all the bad news is from Pentax -"On August 4, Niko...

Pentax FA 70-200 f2.8 release date pushed until next year
I intend to sit back and see what happens - I would prefer to wait and have it released once it is properly ready :D There could be many reasons for the delays, I prefer to see what transpires and then make up my own mind :D I hope that the full frame arrives with a few more lenses and then th...

Pentax FA 70-200 f2.8 release date pushed until next year
Apple once released a version of their iPhone late because it simply wasn't ready. The decision was expected to adversely affect their stock market price but it had the opposite effect in fact their share price rose as a result of their decision, which was deemed very brave. But as Steve Jobs said, ...

Pentax FA 70-200 f2.8 release date pushed until next year
I heard a rumour that it was delayed due to a re-design of the plastic end cap :shock: The new one will be similar to the excellent Sigma ones :mrgreen: Can I suggest that they also bring back the original Ricoh body cap from the film era. Thicker than the Pentax ones and easier to grip :D For...

...The whole Pentax Full-Frame circus is surrounded by rumours, anticipation, announcements and delays... The prototype "somewhat non functioning" model was shown and announced by Pentax as far back as September of last year, Not really much that's rumor about that one. But on the flip side, ANY qua...

Looking for a general use quick lens with 'macro' capability
The short as is that it won't. By definition a true macro lens gives a 1:1 ratio, like your Pentax 100mm macro. Other zoom lenses with a 'macro' setting generally don't and although you can get close-up it's not as close. I have the 100mm macro as well, and if you want macro then that or similar mac...

Sigma EX DG 300mm F2.8 V Pentax DA 300mm F4
Hi all, Anyone with hands on experience of the Sigma EX DG 300mm F2.8? Was wondering how it compared to the DA 300mm. Focus speed and image quality? Compatability (sigma lens) with the DA HD 1.4x converter? Any feedback appreciated. Slightly off topic. Anyone with the K3ii? Wondered...
