Chris, I don't know if my camera club is reperesenative, but I suspect they will all be roughly similar. We have about 18 members who use film cameras, some of whom only take slides, while others only go for mono prints. Some of these people have compact digital cameras. We would have about another 12 or so that have only compact or bridge cameras. The rest (about 20) have DSLR's, many of whom also have compacts or bridge cameras.
There are makes and models, icluding folk who swaer by their (older) Nikon D100, Canon 300D or 10D. Of course we do have some folk who have all the latest kit as well!
I find my camera club to be a 'little community', and the web site haelps with that. People are so freindly and willing to help. For example we had a beginner who just joined with us in Septmeber and in his first competition came second overal in Colour and his print was to entered in the Regional level competition. However in order to enter his print had to be properly 'mounted'. As he was just new to the club and didn't know what to do some members arranged to show and teach him how to mount the image for the competition. Needless to say the new member was most impressed!
I must admit I did visit two other local camera clubs before I joined the third. The first two left me standing about like an eejett, largely ignored me and left me feeling rather unwelcome. After just a few minutes in the third camera club I knew it was the one for me.
I agree with matts that the club competitions can be good fun. Simply looking at other peoples' photos and then listening to the judges comments can be veru informative.
