RE: Digital camera in scale models!
I have a Kodak EasyShare CX7300. 3.2M. Fixed lens. It's 110x65x40... somewhat larger than the 530.. It's fittable in a larger plane.
The only going for it really was the price at the time, abt $100 if memory serves.
I use it as a walk-around when my Nikons are in service in planes.
Something about the software irritated me, so I deleted the software, and use what came with a Casio instead.
