my Canon 450D DSLR has served me well for photometry for about 18 months but the USB connector has broken. The Canon service engineer will attempt a cheap repair but suspects it may require a new main circuit board. If so it would be more than half the cost of a new 600D body.
I would appreciate comments (positive and negative) from anyone using a 600D for photometry. Has anyone measured the spectral response of this model?
What other camera models are people using? Is there a preferred one, and why?
Thanks for your help.
