Customer Reviews

Interface not great

Use regular inertia dials for the interface. The simulated camera controls are difficult to read. Also no one thinks in decimal feet, change the calculation to show feet/inches. People will REALLY appreciate that.

Educational tool.

Great for the beginner or someone who just made the move to a DSLR or one of those great 4/3 jobbers.

AVOID IF YOU HAVE A FUJI!!!Agfa, Minox, and Practica, but no Fuji?!?

Not sure why Fuji got omitte when there are so many small makers included, but as a dedicated Fuji owner, I'm surprised by the snub, and will be waving others away until it gets fixed
