Thanks guys - more to consider!
But, my DSLR coice is already made for me by the fact that I have Canon L series lenses. That investment has me by the b..ls!!!
So my only consideration now is about a compact digi-cam. In this I am not really looking for good DSLR capabilities - it will be a "diferent horse for a different course"! It MUST give me the convenience of reasonable compactness - not like a credit card camera, but around the dimensions of the Canon G9 or G10. No images from it will be printed beyond say 8x10 inches.
I am very aware I must not look at small digi-cams and be thinking of high end DSLR capabilities - I must be carful to be thinking about good performance up to prints around 8x10 inches.
When I read some reviews of cameras like the Canon G10 - the only negative comments are ones that really are comparisons with good DSLRs - unrealistic and stupid reviews. A G10 or small cameras like it just can't be expected to deliver such results (even though I do want the best possible image quality from it!!).
And then there is the option of the 4/3rds Panasonic G1..... and maybe with a PRIME lens only of say 20 to 25mm giving me a 135 format angle of view like a 40 to 50mm lens!!!............................ Mmmmmmmmmmmmm!
That Sigma Marc mentioned seems very attractive - and with it comes a decent size cropped 35mm sensor! I am used to shooting Leica M with one lens on all day - it just has to be an angle of view and the Sigma has an equivalent of 41mm in 135 format, which I really like.
So, yes, I will go and annoy sales staff in various stores and play with the ones that have some appeal to me and then look at the results.
