cumi said:Let me use this thread for my question about lenses:
There is a parameter for lenses like:
Camera A (Canon G6):
7,2 - 28,8mm (35 - 140 equivalent)
Camera B (Powershot A520):
5,8 - 23,2mm (35 - 140 equivalent)
Which one is better? How can I see it / calculate it?
Unimaxium said:...The G6 (...) has a larger sensor than the A520.
Unimaxium said:EF is just a name Canon gives to their line of SLR lenses. It's not really important to know what it stands for (I don't even know).
