I am looking at getting a K-R but have seen a couple of mint K20's. I shoot mostly landscape at base ISO,one obvious advantage of K20D is that I live on the Isle of Lewis which = rain.
Is a used K20 a better option than a used K-R ?

I had a long look at the Nikon D3100 which has staggering high ISO performance, but the Nikon matrix metering is really bad at clipping/blowing highlights.
Trusted Reviews has a review of both and the D3100 shots have blown highlights all over the place,the K-R however has really good set of test shots in what appears to be very similar light and nor a clipped or blown highlight to be seen.
The TR review also praises the 18-55 DA-L for turning in an excellent performance.
The real attraction for me is that I can get a 16-45mm lens for less than £200 used ,whereas the Nikon 16-85 is nearer £400,longer reach but if the 16mm end is what is needed then the Pentax seems great value.

Where are Wales going ?

I have decided on the K-R, every review places it above the K-X and although it may be more than I need that is probably true of most mid range dslr,s.
Many thanks for the advice and comments from the forum.

How much of an issue is highlight clipping ? dpreview suggest that it is an issue on both k-x and k-r but I would value users views.
My D40 had flawed matrix metering which had to have -1/3 applied for contrasty shots, is this true for the k-x and k-r?

I am looking for a new dslr and am torn between these.My previous Pentax dslr was a K200D and I wonder if these are an improvement?.

The K-X seems to have the same sensor as the Nikon D5000 which has a very good reputation but there is the issue of AF points. I do not think this will be an issue for me though as I believe it can be set to the centre points which is the same as my previous dslr,a Nikon D40.

I shoot landscape mostly and 95% of my shots are at base ISO, would the K-X be ok or is there an advantage in the K-R?.
I assume the IQ will be the same in both at base ISO.
My ideal lenses are the 16-45 and 18-250 and of course a K-X would mean more of my budget could be available for lenses.
Having said all that K-R prices are dropping on the auction site and here. I would value any input to help choose.

Many thanks to you all.

I am looking at a K-R with the 18-55 & 50-200,anyone care to advise on whether they are good or not?, is the 18-55 the same optically as the other 18-55 Pentax lenses?

Many thanks for the help given, but the Tamron has dust and whilst its not an issue that could change. There is a Pentax one on eBay but is unboxed with no hood, am prepared to wait but aware that it may be a long wait.If anyone does see one anywhere I would appreciate a heads up.

Thnaks, yes the Pentax and Tamron are basically the same lens but finding one is not easy.
I have never understood why Pentax discontinued it or did nor replace it. With shake reduction bodies it makes for a great travle/one lens solution.

Anyone have one they no longer need, now becoming hard to find.
