Thanks for the info, very helpful. I like the idea of having a really good "grab and go" camera, I was thinking of getting the Nikon 28-300mm so I could use that on the D800 as a grab and go set up, still missing the longer end for wildlife though, interesting option with that Sony as it covers it all it seems, I might have a play with one if I can find one in store somewhere.thx, warren, it's a nice camera, results are very good. i had an earlier version of this a few years ago for a summer trip and it was perfect. i didn't want to lug the nikon but wanted to have something with good low light performance and reach of an 18-300 lens. so that sony pretty much filled the bill. after the summer, i ebayed it and recovered most of original cost.
this current version further improves the focus system, expanding the number of focus points. again, i'll use it for the summer then probably sell it. biggest downside, is simply having to navigate through sony's arcane (to me) settings and menus.
