Hi Stefan, thanks for that, having not used LV I was wondering just what it was doing, my K20D seemed a lot more positive.
You should be comparing like for like, liveview is very different then normal shooting.

In 2008 Pentax had only a small showroom but they had quite a big space for customers behind the stage. Last time it wasn't that bust there so it's good to see it's more busier now.
The stand now looks bigger than it was the last time but they did had 5 small pillars with the K-M on it on with a steel cable so that you could try them out yourself without waiting for one to be handed to you. Was that the same this time?
last time Canon was also almost had a whole hall, they were sharing it with Panasonic then.

The K5 has 14-bit per pixel RAW output, vs the 12-bit per pixel RAW output of the K7 and prior. That, plus the extra pixel count means more RAM usage. I also expect that the K5 firmware is going to use more RAM compared with the K7 - so they've probably got the same SDRAM amounts internally.
I think if you want to fill the buffer the K7 can do maybe 4 images in that time? since the K5 files are larger and the buffer filled faster, I would be surprised if it could do 2 images before the buffer is full.

Could it be with that in order to achieve the high ISO, severe processing is required which slows down the process. While RAW does not need to have the JPEG conversion, it probably still has processing in it to get the high ISO...just speculating

RAW is just the data from the sensor, so the sensor gives the DATA and the camera simple pack it in a file, so no noise reduction or anything is done by the PRIME II processor.

What I do not understand is this; when in the past I have shot in rain water drops on the front element have made the images un-usable. Do the WR lenses have wipers?

I have a gitzo tripod with a simple gitzo ball head. This has one lock to hold the ball in place.
I find this a bit fiddly if I want to change the pan or tilt only, and am looking for a new head. The off-centre heads look like the solution http://www.gitzo.co.uk/product/72038.71852.83184.0.0/GH2750QR/_/Series_2_Mag_Off...
Anyone got experience of these, any pros and cons ?
I think it's very handy that the camera stays at roughly the same height if you switch from landscape to portrait mode.
I've tried the head out in the shop, they feel very good but they are quite expensive though and sadly don't have the cash for one
For the little bit extra I would go for the series 3 that can hold 8KG instead of the series 2 5KG.

Aah right, I must have missed thst, I've watched the video a couple of times and the AF seems to overshoot then track back before locking on. Considering the subject and lighting my K20D with DA*16-50 would have nailed it perfect, but not sure about LV because I never use it. I was not that impressed TBH

With Phase detection the camera know if to focus backward or forward and knows better how much it needs to focus.
With contrast the camera need to focus backward or forward to know if where to focus to and it seems the camera overshoots a little to see if the contrast improve and then goes back to the maximum contrast point.
The good thing is contrast AF is more accurate since you are measuring the focus on the actual photo.
