It means that 1 pixel in the photo is 1 pixel on screen. This means zooming in further will give no additional detail.

Why not switch to Olympus? Nice bodies, IS, plenty of big zooms of the kind you seem to like ...

Or you could stick with Pentax and start using smaller, screw-drive primes like the Limiteds. In my opinion, if you're not shooting primes, there's little reason to stay with Pentax. Pentax = primes.
Really poor noise on Olympus?

Sony may be a better option as they have IS.

I shoot with Pentax DA* zooms. I chose Pentax for the weather sealing originally. Nothing wrong with Pentax zooms, the image quality is very good as is the resolution.

Thank Tyr & RParmar !

Dave & Tyr. Pentaxian is correct. Very low light levels meant the 6,400 max ISO (I was shooting in TaV mode) was quickly reached and was actually probably lower than it should have been. It was an impressive performance from the K5 and both Pentax lenses.

Actually this has reminded me of one other point of note - the DA*300 shots were slightly better exposed than the 60-250's (@250) which looked a tad under-exposed. It would seem that the DA*300 seems to gain maybe half a stop over the 60-250 under the identical conditions and using identical camera settings
That would be because a zoom lens has more glass and glass/air interfaces where light is lost. The t-stop value for both lenses will be different. The 300 has very few elements.

Well seeing as it was a provocative first post I think so too...

Interesting idea. I just need to get out with my camera some more.

Sunday is not the best day as public transport is poor on Sundays.

Just a quick 5 min job. I think I have seen a clear winner already.

I've just helped the wife finish a bottle of red she was given from a client, "Brewery Hill" 2008 South Australian Shiraz, I must say the bottle looked totally unimpressive with a plain label and screw cap lid, the contents were however one of the nicest reds I've had for a long time.
Something to watch out for on the supermarket shelves methinks....hic!
LOL, we're just finishing a bottle of red (from the Cotes du Rhone region) from the co-op. Bought two a few weeks ago and it was very good. they have loads on clearance now, nobody seems to be buying them except me! I have to finish it before I go to bed, not going to waste...

I still loved the 60-250, the AF didn't feel slow and even in the shop at 6,400 ISO
As a relative newcomer perhaps I am missing something here, but surely the ISO setting on the camera has no effect on the speed of focusing?
I thought that was due to the lens characteristics and maximun aperture.

Indeed it won't have any bearing... :S
