Hi,
I now have my D300 & converted Nexus D200 housing to accomodate
D300 by just changing the base plate. This base plate was made by local
machine shop & can be changed with single allen-wrench in 10 min.
All major function bottons/dials in front & top are working/are in-line with camera,
except 5 bottons in real as marked and lenses are contered. To me, difference is
on thickness & D300 is about 2mm thicker than D200 as shown on the base plate.
I like 'Live-View' function of camera(you can focus while you are watching LCD
and/or through LCD like p&s camera) and low noise on high ISO.
Sam.
