For a bit of fun, I'd be really interested in the camera that always seems to 'surprise' you... the one that you might pull out of the cupboard every now and then and love the results...
For me it's the Konica S2. It's not the prettiest camera and the ergonomics aren't wonderful, but I am always pleasantly surprised when I dev a film and do some prints. That lens has a really nice quality to it... the best $20 I have ever spent.
I also handled a Leica IIIf for the first time yesterday. It's damaged but I LOVED just holding it. That camera seems to fit my hand perfectly. That was a surprise I guess ;-)
Anyway, I am interested in your surprise cameras! Thanks.
