Thanks. I found the user manual on line and it doesn't look as if it's possible.

There is an interesting survey on DP Review at the moment:-

"Canon EOS-1D X Mark II Vs. Nikon D5"

Answer Options:
1) I'm a Canon user and I'm excited about the 1D X II (13.1%)
2) I'm a Canon user and I don't care about the 1D X II (10.8%)
3) I'm a Nikon user and I'm excited about the D5 (13.1%)
4) I'm a Nikon user and I don't care about the D5 (9.9%)
5) DSLR is yesterday's news. Bring on the pro mirrorless! (38.9%)
6) Canon? Nikon? I'm waiting for the Pentax full-frame (14.2%)

Sample to date: 5,375

So, slightly more DLSR users are interested in the Pentax FF than the latest Canon & Nikon. Maybe because if things run to form it will be cheaper.

You have a PM.

Hi Bruce,
can the MX-1 take a screw-in filter? In know it has a bult-in ND filter; I'm thinking of a circular polariser.

Als0, can focussing be assigned to the 'AV / AE-L' button?

Hi.
I have one of these and it is very good when I can. I use the Peak Design two-part wrist strap with it so it is always attached to me somehow.

The only problem I have is that it isn't deep enough (screw length) to fit the rucksacks that I use regularly. I suppose I could look for some longer screws or ask Peak Design if they could offer some longer ones. The screws have wide tops with knurled edges to enable them to be tightened by hand.

If you get a chance, try one out on the bags / straps you are likely to be using.

Camera Centre UK also have the K-3 II at £650.

The K3 is also at the same price and in the next picture, so pgweber's caution applies here too.

You have a PM.

Nor a dealer I know. but I had no problems with a few lenses bought from individuals via eBay in my pre-Pentax days (Canon FD).

SRS are offering the K3 II for £649, £100 less than at WEX
(http://www.srsmicrosystems.co.uk/cameras/interchangable-lens-cameras/pentax-dslr... ] here[/link]).

There is a used (Condidion 10) KS-2 body or £254 at WEX (here).
