Next in wish list. With this will be able to do incident light metering which should give more accurate exposure compared to the reflective light metering provided by the camera. The bad part would be this is a handheld device which has to be carried seperately. It would have been nice if it had a flash shoe mount so that i can mount it and leave it there. Even better would have been to get a watch or a mobile which has a inbuilt light meter just like they have calendar,stopwatch or organizer. But looks like these devices are not yet photographer friendly :(
