Hmn ... maybe I should plump for the new standard kit lens and add a Sigma 10-20 instead of the 16-45. Of course I'd really like the Pentax 12-24 (I think) but not sure I can justify the expense!

There is less CA with the new 18-55 than there is with the 16-45? I was thinking of getting the latter with the K20 body ...

I don't have it in front of me so won't attempt direct quotes. Main points though were that they had issues with the AF performance, the Live View mode isn't as sophisticated as others and there is evidence of some purple fringing on some shots, eg with trees against a bright sky, that may be due to the sensor.

Overall, however, they felt that the image quality was superb!

As a potential purchaser, my only concern may be the purple fringing - they detected this with 2 lenses.

There has been some mixed discussion over on DP review:

K20D review in next week's AP, Tuesday 8th April

Hi All

I am looking at upgrading soon too, currently have an ist DS (though I do also have a 10 Mp Sony R1).

Does anyone have a definitive list of the main deifferences between the 10D and the 20D? My impressions so far from various threads are as follows:

Resolution - 20D 14Mp, 10D 10Mp
Sensor type has changed to CMOS in 20D
Less high ISO noise in 20D
Live view in 20D
Larger LCD in 20D
AF more precise in 20D?
Shutter quieter in 20D?

Anything else to justify the £400 difference in price currently?

Thanks
Lee

Before I send the body off for a repair quote can anyone think of a legitamate circumstance where this would happen?

i.e. I press shutter button half way, get focus lock confirmation in viewfinder and audible beep and then when pressing shutter button fully, camera refocuses before taking the shot?

Lee

Thanks Pete. I think I have checked every combo possible. I'll have another look.

Dear All

I have a *istDS with the latest firmware.
I have it set to use AF-S, i.e. single shot AF mode.
I use the apertue priority mode.

My problem is that I expect the camera to lock the focus when pressing the shutter button half way *and* the focus lock indicator is lit. This works most of the time but sometimes when I go to press the shutter fully, the camera shifts focus again before taking the shot. E.g. if I depress halfway, lock focus, move camera slightly keeping button halfway depressed - it can make the camera hunt again for focus. Is this normal?

If I change the settings such that the OK button does the focussing, this seems to work. In fact this is a useful feature as I can focus with OK button, release it and then press the shutter button to take the shot.

Anyway, I was wondering if I have a faulty camera regarding the above problem? I seem to remember seeing some reference to this a while ago when trawling the net for answers.

If there is a fault, does anyone have any idea how much it would cost to fix? I ask this because I am thinking of upgrading from to K20D and would like to 'donate' the DS to my partner but only if it works properly the normal way!

Thanks

Lee
