I'd expected this thread to move a little faster.

All good choices and I must say a very difficult decision to choose just one. I have a list of three that I'd deem a perfect set but I did ask for one (and I already broke that )

What is your most wanted lens and why? (can be unreleased)

I think I'll have to post two

Pentax SMC-A 50mm F1.2

Fastest lens available, very soft wide open with shallow DoF. Very sharp stopped down a bit, very clear. Inside my perfect FoV (40-90mm) and perspective (40-60mm) range.


Pentax SMC-DA* 55mm F1.4 SDM

Similar reasons plus fast AF and weather sealed! Hopefully it will also be available unlike the old lens which is hard to find, not as hard as other lenses though.

You wouldn't happen to have any news on the DA* 55, 60-250, 200 and 300?

I assumed the K100D Super would be available a the same time as the SDM lenses, otherwise it would seem a bit pointless.

£450 for the K10D, should have waited as I've not had much of a chance to use mine yet (lots of rain here in Yorkshire!!!)

Well, at least getting a body for my other half is looking easier

How much for the Grand Prix Ltd Edition (not that I want one as I don't like the look one bit)?

Nice to see there is no change on the lenses

Don't forget to feed your organic lens though otherwise it will die and the animal rights activists (well extremists) will come after you!

That is because beer reduces the processing speed of the brain because of the increased interference. All sorts of problems can arise in processing because of the beer. Try the same thing on your Pentax, I'm sure it won't be happy.

Actualty, the eye doesn't need multiple dedicated lenses as the angle of incidence of the different fluids in the eye also helps focus light.

So you have the Cornea as the objective lens, then in the same element you have the Aqueous Humor followed by the lens and the Vitreous Humor.

That is 4 'lenses', 3 of which change shape (the Humors have to change shape to accommodate the change in the Lens which further changes refraction and the way light is focused).


Plus some of the most advanced world reconstruction and simulation software in existence.

That is quite bad CA on the Sigma, the Pentax performs well though.
