It’s been more than 2 years since D90 was introduced, although it’s still a highest selling DSLR today, there are bound to be some nick knacks to iron out in the firmware.
I hope they release a firmware update soon to make it more robust, so that users keep the D90 as a second body.
I don’t know why I say this here, but I want to say it anyway: When I was using my P&S Nikon P6000, it had a fabulous feature a customizable user1 and user2 settings on the PSAM mode dial itself. I was able to set those two to any mix of settings that I would use frequently.
For example if I was shooting a basketball game indoors, and found that the following settings worked well for action shots, I could set user1 to: 1/800s, f/2.8, ISO 400, WB=Incandescent, NR = off, VR = Off, Matrix metering, Distortion = off, etc.
Whereas I could set user2 to following settings for non-action shots in the game: 1/25s, f/2.8, ISO 200, WB = Auto, NR = off, VR = off, Spot Metering, distortion = off, etc.
How do users manage their set of favorite settings on D90?
