I noted this comment in the review, "Distortion and chromatic aberration correction for DA and DFA lenses (also available in RAW conversion when using supplied software)".
So, could the software supplied with the K7 be used to achieve the same with RAW files from another camera - a K20D? Anyone with a K7 tried it?

Thanks George. Really need to get my head around what I want to do! (then give it a try)

Thanks for the input so far!
Optical triggers = my words for the light-sensitve slave type switches that respond to the main flash and trigger other flash units plugged into them.
I take the point about using older lenses and flash units on manual, but I'm looking to use my DA lenses.
As to where/when I would want to use all this kit together, I suppose it could be described as 'studio'. My thinking is to use the 36PZF on or close to the camera, with the 2 x PE-3057's at the side or rear of the model.
I like the suggestion of wireless (as in RF) devices. Presumably the transmitter is a camera operated hot shoe mounted device (or connected via the X-sync socket) and each of the flash units has a receiver attached.
I have a flash meter that I would then need to use with the set up to determine corerct exposure via a series of test shots?

I have a K20D, a Samsung SEF-36PZF flashgun, plus 2 x National PE-3057 flashguns. I'd like to trigger the PE-3057's to fire (remotely) in conjunction with the K20D/SEF-36PZF, but understand I can't use optical triggers as the P-TTL pre-flash will fire the PE-3057's early. Anyone have any suggestions/recommendations for how I could get this kit to work together please?

I note in this article that Canon recommend making any adjustments at the long end of the zoom range.
Are there any other views/suggestions about correcting zoom lens focus errors?

I did some print test on my camera k10d lens 18-55mm and on a t-pod with remote realise and I've defiantly go a problem with my focus. i was getting only sharp in the centre of the shot but at f32 i expect all of the focus screen to be sharp ?
So i went to manual focus and it was like my eyes had been cleaned
what i would like to know where is the focus adjustment in setting/debug mode

From what I've read it's something you have to enable using third party software. Take a look at this link>linkI did some print test on my camera k10d lens 18-55mm and on a t-pod with remote realise and I've defiantly go a problem with my focus. i was getting only sharp in the centre of the shot but at f32 i expect all of the focus screen to be sharp ?

Seems a lot of members have gone down this route, so you should get a lot of very helpful advice here
Now SOLD! Thanks for the interest

I've just bought a K20D, so my K100D has to go, complete with 18-55 kit lens plus manual, leads, etc. Boxed.
The camera and lens are as new, no marks or scratches. The body has 763 shutter actuations recorded; kit lens not used, but has been on/off body.
Both camera and lens were bought new in late January 2009, so nearly 4 months warranty left.
£200 inc. postage in UK.
