I'm involved in the choice of a flash for my camera (canon 50D). I'm searching trough the net to compare the models of several brands.
At the moment I'm considering the Nissin Di866 mkII as the best choice, as it is considerably cheaper than Canon 580EX (half the price) and its specifications are very similar to the Canon's one.
as reported on this review
some of the differences between Di866 and EX580 are the following:
Di866 isn't able to adapt its zoom on the sensor size
Di866 has a minimum recycle time of 5,5 s versus the 3,8 s of the 580EX
580EX hasn't the optical slave mode
580EX hasn't the seconf flash tube for fill in
which of these are most important?
I've still to watch to other brands, as Metz, for the AF 58...
what is your opinion about these gears? Any other suggestions?
which flash would you recommend?
many thanks in advance for the help
have a nice day
