M410 is 4MP compared to A610's 5MP.
I admit I only learn on Kyocera Finecam M410R from this thread. Originally, you mentioned what matters most is Pic quality, and Jeff Keller's comment on the link I provided above: "Dull colors in photos; images look fuzzy and soft; vignetting in most of my test photos". It's true you can zoom in more on the action but will the photos be satisfactory?
