Hadn't seen that before, it'll be appreciated by many. The K-5 now has 5 user modes. However, there is only one user mode position on the mode dial and you'll have to select which one of five modes to use.

Don't forget your own hands on preview this saturday in Watford!
All being 'well' I'll be doing a workshop so won't be able to come. Having said that, at the moment there aren't enough people booked on to run it. One more though...Don't forget your own hands on preview this saturday in Watford!
Which puts me in a dilemna - earn a bit more towards the K-5, or go and have a play with one (and the 645D). Win win really.
Keep meaning to ask Chris if he's going to have the demo K-5 knocking about for a while, will pop over there in the week if so.

Nice to be close enough to be able to do that, unfortunately it would be a long trip from here.
Best regards, John

This a good feature.
I use the AF button for focusing meaning I hardly half press the shutter release.
10.3 Shake reduction
I could find no differences in the shake reduction feature. The specification didn't change either. However, there is a small change I noticed nevertheless: When you half press the shutter, the SR needs about a second to get ready. About the same for K-7 and K-5. But if you unpress the shutter, the SR stays ready until the VF INFO row is switched off a couple of seconds later. With the K-7, it didn't and another half press always had the delay for SR to get ready again. This may be a huge difference in certain situations. If it wasn't simply a display bug, then or now.
+ good news for those who are worried about the DFS at long exposures.
10.5 Bulb mode and DFS
DFS (Dark frame subtraction aka Long exposure noise reduction) can now be switched off even for bulb mode (exposures longer than 30s). I made a test with a 66s exposure at ISO 1600 and the image displayed immediately and the camera was ready again -- without a delay (firmware 0.30). ISO 1600 is the highest ISO setting for bulb mode. This is no limitation for raw shooting though because higher ISO are made in camera from ISO 1600 by exposure boost post processing; something easily done in the raw converter as well.

No but good non the less though.
It's btw interesting to read that the sensor actually goes up to ISO1600 and the camera can push it higher.
Most likely it's the same for other camera's so I wonder how much there is to gain with shooting at high ISO and RAW.

I guess the experiment is shoot a scene at 3200 or 6400 ISO, and then without altering shutter speed and f-stop take an identical show with the ISO down at 1600.No but good non the less though.

Then boost the exposure of the 1600 shot in Lightroom or something and compare.
I'm presuming that the ISO upto 1600 is done by altering the gain of the sensor, and above 1600 it's done by digital gain. ( Both methods of course will boost noise )

Yes with the K5, I said that I wondered how it will be with the other camera's.I'm presuming that the ISO upto 1600 is done by altering the gain of the sensor, and above 1600 it's done by digital gain. ( Both methods of course will boost noise )
Where the limit is of the sensor gain.
