You are welcome.

Thought you might like to have one at 250mm.
These guys are waiting their turn to go into smoke filled rooms during simulated training last Sunday of new Fire Fighter recruits. One can see the concern. (I mean thick choking smoke, with respirators of course)

Here is some architecture at 35mm. Same day.
I really like the window reflections one can see when the image is enlarged. I could make a very good big print of this one.

PS. Don't tell me the Brits have even picked up the gang slang word DISSED.
You will soon be flying the Stars and Stripes over Buckingham Palace. Ha Ha.

Precisely my sentiments.

I used my size slider on iPhoto and increased the image to almost double the size on my 20 inch screen and it is still a pretty good image.

Might add, I didn't take any time with the few the images I shot that day, as I was in a hurry. They were just quick shots in a couple of areas of the town.

Are you sure you are not mistaking the green for moss, there is lots of it on our trees right now including the ones in the shot.

ChrisA.

Is this the area you mean ? RG.

I have the Tamron 18-250mm (The Pentax is the same lens made by Tamron)

It is a great lens, better than all the lenses you mentioned.

Here a couple of shots taken yesterday with K10D at 18mm.

With all due respect to John R, I don't any problem with lines.

The blower I am using is only two weeks old.

I just use the same procedure I have always used for years, starting with SLR's and my other over 3 year old DSLR.

You could be correct in overkill, but it's mostly the end of the lens I use the blower on, don't see where that could cause a problem in the camera.

Never have changed lenses on a Fire Dep't shoot, I either take the Pentax fitted with the new 18-250. Or I take two camera's with different lenses fitted.

RG.

John,

Thanks.

I locked the mirror up once again, held the camera under a bright lamp and gave it three good blasts with a Rocket Blower right above the sensor. You would not believe the big chunk of debris that flew out of there. Certainly big enough to see in the palm of ones hand (If I could have found it)

How on earth could something that big get in there is beyond me. I am very careful changing lenses, I never ever put a lens on without using my blower first and have not had the problem with my other over 3 year old DSLR.

I am beginning to wonder if it was floating around in the body from new.

Anyway thanks to all for the help.

Cheers, RG.

Thanks to everyone for all the suggestions.

Gwyn.

As requested, here are a couple of samples.

It was a very dull overcast misty very cold morning and of course lots of smoke for the training session.



Right by the hand.



In lower area of smoke.

Thank you, RG.
