I got into mirrorless - specifically m43 - because of the tradeoff between good enough IQ and small size. My forays into even APS sensor cameras has been limited due to size, but almost always lens size - the bodies are plenty small but the lenses aren't. Some medium wide to standard primes are OK (plenty of examples from both Fuji and Nex) but the zooms, longer lenses, and ultra-wide lenses get beyond my comfort zone pretty quickly. I loved the Fuji 55-200, but it's just too big compared to m43 lenses with considerably more reach and similarly good optics. I have the Fuji 14mm, which is borderline too big, and will no doubt check out the 10-24 UWA when it shows up, hopefully soon. But my guess is it's gonna be bigger than I'm gonna want to live with. Which could chase me back to m43 as my "system", rather than the mix of m43 and Fuji I'm using now.
Enter this Sony full frame mirrorless system. To my surprise, I fell totally and fully for the RX1, but a lot of that has to do with getting full frame quality in such a compact package, with it's slightly wide lens. Any time I've even played around with a full frame DSLR in a shop, it takes me a matter of seconds to realize I don't want anything to do with bodies and lenses that big. My strong suspicion is that anything outside the 28-55 range with this system is going to have an even worse case of outsized lens-itus than the APS gear that's already bigger than I like. Which is why I seriously doubt I'm gonna have a lot of interest in this gear. I hope I'm wrong - if they can give me a 24 or 28mm lens in a package that's even close to the size and quality of the RX1, I'll probably get interested pretty quickly. As it is, I'm having my doubts. I'm sure it'll be excellent gear, but I doubt it'll stay within my size and weight threshold. I'm sure the body will be small enough, but I doubt the lenses I'd be interested in will be.
