The other half had a pique of madness and allowed me to get a Sigma 500mm f4.5
Sorry George

What lens?
There are not many possibilities.
It's not a mirror because Chirpy has used different apertures (and there are no doughnuts, and they're quite sharp).
The Pentax 500mm is a pig to use because of the metering and manual focussing. So it's probably not that.
Can't be a Sigma because the pictures are too good.
So it must be an old MF Tamron. Or a Novoflex.
Correct?

Come on chirpy don't keep us in suspense.
I got to handle a K20 in the store today, but thats as far as it went, it didn't have a battery in it. Not a great deal of difference to the K10 in respect to its feel and looks

As quoted on the digidirect website
Product Information
LAS VEGAS--Pentax just announced its new flagship SLR camera, the K20D, but the Japanese company has plans on the drawing board for a higher-end class of camera in 2009.
On the Pentax roadmap for 2009, the SLR quality arrow jumps up "much higher" above the K20D--a bigger step up than the one from the K10D to the K20D--said John Carlson, Pentax's product manager for imaging systems.
"That would be a new category" of SLR for Pentax, he said, but was mum on further details.
Obviously, that statement leaves a lot of room for maneuvering and interpretation, but it's still a notable reflection of the company's ambitions. Pentax also must reckon with some powerful competitors with high-end models--not just market leaders Canon and Nikon, but also well-funded newcomers such as Sony, which plans to release a professional-grade SLR this year.
Pentax announced its K20D last week and is showing it off this week at the Photo Marketing Association trade show here. The 14.6-megapixel model includes features such as 11-point autofocus, sensor-shift image stabilization, ISO up to 6,400, and seals to keep out dust and water.
SLR (single-lens reflex) cameras offer higher image quality and interchangeable lenses, but they're more expensive and bulkier. SLR sales are growing faster than the overall digital camera market, so it's no surprise camera makers are fighting for dominance--especially because the market is in flux.
Pentax, like Canon, Nikon, Fujifilm, and Olympus, is a traditional camera maker facing new competition from consumer-electronics powers such as Sony and Panasonic. Sony got a leg up in the SLR market by acquiring the assets of Konica Minolta, and Panasonic has a partnership with Olympus and Leica. Another electronics giant now selling SLRs, Samsung, bases its products on Pentax cameras.
One way Pentax could head toward higher-end SLRs would be to follow Canon and Nikon with models whose image sensor is the size of a full frame of 35mm film. Most digital SLRs, including all of Pentax's, employ a smaller "APS-C"-sized sensors that are cheaper to make. Larger sensors offer the promise of greater sensitivity because pixels are larger, and for 35mm film buffs, lenses give the same field of view as they did with film.
But don't expect a full-frame Pentax, at least for the time being, Carlson said. Asked whether it was in the plans, he said, "At this point I would say no. The lenses are designed for the APS-C format," Carlson said. However, he qualified his remarks with a disclaimer: "What will happen in two years? Who knows."
One interesting feature in Pentax SLRs is support for the Digital Negative (DNG) raw-image format, which is Adobe Systems' attempt to curtail the cacophony of proprietary raw image formats. Raw images provide more quality but require manual processing into something handy such as JPEG, and different SLR models typically have their own proprietary formats today.
Pentax is probably the most notable DNG adopter, though others include Ricoh and now Epson with its super-high-speed camera. However, DNG still plays second fiddle among Pentax photographers to the older PEF format, Carlson said. "Most people are shooting PEF," he said.

Comment by Clarky posted on Removing lens elements at 28/02/2008 - 20:32
I have an old Pentax 110 70mm lens, I have remoed the front element for cleaning - there is fungus in the lens and I decided to attempt the cleaning myself.
However, I am unable to remove the next element (possibly due to it being too tight) and am presuming I might have the same probles witht the other elements (there are 5 groups in total). Does anyone have any experience with this and can suggest a way of loosening the lens retention ring? I am asuming I am turning it the right way - the same way as for the front element.
Would WD40 be a way to help? I am using a fairly standard lens tool that looks a bit like two scredrivers linked with two bars bit like this one: http://www.pictureline.com/products/2527/Brandess_Kalt_Lens_Spanner_Wrench/#
Any suggestions would be appreciated.
I certainly wouldn't be putting any oily fluids in there

Did you say you are from "deepest Hampshire"? Hmm.

PS: Nice pic, by the way. I presume that's Hyram's boat.
Nice Shot belinda, I would have gone for a tighter crop on it personely.

Yes he does. As many as he can get into. And he likes to blow bubbles on the birthday cake!
