You could try the Photo Filters if you are using CS2. Maybe an 81 or 85 filter will help. If all is lost though you could always convert them all to monochrome and tell everyone you are doing it on purpose...

Made from girders, as I understand it...

George was making a droll remark, or at least I hope he was....

You can come along as well, George. I-O-M is not that far away...

Of course, but it still needs an oragniser!

It would be very nice if a few of us could meet up in the Manchester area.

Unfortunately I don't have the time to organise it, but I would certainly attend an event.

As it is, myself and Kevin Stephens are both members of ADAPS, but that's the closest to a PentaxUser group that we have.

Is there anybody out there that could make something happen? :

The K mount version is self explanatory and absolutely huge. It is intended for professional field sports shooting. Makes a great telephoto but wouldn't be a very good substitute for a 135mm lens!

The "screw mount" version is also a bayonet fit lens. The rear portion of the lens screws onto the camera body and then the lens bayonets in and out of that. I should imagine that this version is very rare indeed.

I have no doubt that some Sigma, Tokina, Tamron or other independent lenses are very good indeed in terms of sharpness and/or resolution, Kevin.

What I have found over many years is that it cannot be guaranteed, which can lead to expensive buying mistakes, and it's cheaper in the long run to bite the bullet and buy the proper Pentax lens.

But it's not only performance that counts - it's the greater likelihood that filter sizes will be more uniform, colour transmission will be more consistent, focusing and aperture rings will all turn the same way and the Pentax lenses also tend to be more compact.

So I made a "Pentax only" decision that also includes accessories such as lens hoods, even filters when I can get them, and I have been pleased with that decision.

Others are of course free to disagree, and regularly do when they feel so inclined!
