Originally posted by IchabodCrane No question that a light weight body goes well with light weight primes. However, anyone owning a fine prime lens lineup (plus the fish eye zoom) like yours doesn't easily fall into the target audience for the K-S1, at least if that's how you process the comments from the Ricoh exec. I liken it to buying a new BMW and sticking those neon lights underneath it.
Right now I use them exclusively with the K-01 and I find it s good kit. In reality, my most likely purchase will be a K-5 IIs, because I have some zooms too and I think the K-5 and K-01 complement each other well. Same battery, similar sensor, etc.
But if I had to choose just one body to go with now, I would give the K-S1 some serous consideration, because there are certainly times when I'd find three K-5 too chunky to lug around all day. The main reservations I would have are the plastic build and the control changes, which I think would frustrate me. By that I mean the lack of the customizable red button and the video on the on/off switch, which I find too easy to engage accidentally. The mode dial is okay, but the recessed direction buttons inside are difficult to activate.
