Stan, well I do not equate weight with quality which is why I listed both. I bought a D40x as a backup to my first D200 and never did like the size or weight. My wife has a new D90 and even though I use it but I prefer the D300/s etc.
I am very interested to see what the D7000 is capable of. The metering sensor, the new 16MP, better iso and very interested in the m-cam 4800 but will wait until the camera is out and in use for user reports/photos. Will also wait until some sport/bird/wildlife shooters start using and reporting in.
From looking at your gallery (very nice) and coming from a D90 it will probably be a very good choice (although I would probably prefer my D700 ).
Sure, I could get used to different control systems but WHY .
Based on your last sentence you seem convinced by specs that the D7000 is a better overall than the D300s. Could be, but too early to tell. Cheers, Tom
