Originally posted by Lurch The surprise haze been the alpha A99. It has everything I like about my Pentax (weather sealing, in body SR) with that awesome flip screen. It's almost the FF Pentax should make. But im dubious about stepping into a system that really doesn't have the lenses there (tho wide>normal fast zooms they do have).
The Sony
does have the lenses, you just have to spend the money. However, it may not have the complete set you're looking for. But the Zeiss glass is great - for example, the 85, 135, and 16-35 are worth having the system just for them. But each one costs around $2000. I haven't used the 70-200, but it's supposed to be really good too. But there do appear to be a number of gaps in the lineup ...
I think the only Canon to get excited about will be the 7D Mk II (if it ever sees the light of day). Not for everyone, but debatably the best sports camera available.
The K-5 IIs is a worthy upgrade from the K-5, but if it doesn't get you excited then you probably don't need the improvements. Pentax will certainly be releasing at least one new top APS-C this year as well as a FF, and it may be sooner rather than later. I got the K-5 IIs shortly after it was released, knowing this would happen. I wanted to have the improvements for the next 12 months, and it's worked out well. Sometime between the new product releases and the end of the year I'll probably do an upgrade.
But if you don't like what's out right now, save your money and just make sure your lens collection is what you need - whether FF or not. The body's not that important anyway (for most shooting situations any recent body is fine).
