Quote: Since many people want smaller and lighter, why can't companies make DSLRs in the shape of the old Spotmatics and 60s/70s film cameras?
strip away a lot of things like the LCD, the SR system (maybe) the built in flash, hand grip, etc. and you could. Pentax could easily make a Spotmatic style body with a digital sensor. the main things holding that back besides ergonomics, is im fairly certain, battery technology. those spotmatics had very little electronics compared to say a K-5, but with a lot less ‘stuff’ (such as the LCD) you would need less power, thus less batteries. that will equal a significantly smaller body. as the popularity of the
50th Anniversary ‘AP’ edition shows, as well as the new Fuji x100, that if Pentax were to create a ‘retro’ digital SLR that is as close as you could come to a 'digital spotmatic’ that people would snap them up in a heartbeat. (myself amongst the ‘snapper-uppers’) but it wouldn’t be something that a camera company fighting to get from the bottom back to the top can really afford to do.
