jasona1 Posted January 2, 2007 Share Posted January 2, 2007 Need some clarification on the 30D flash metering. My 10D like all previous bodies(?) switched over to evaluative metering mode if I recall correctly. I know that the 30D is E-TTL II but does that change the metering mode? Manual isn't specific on this topic. Link to comment Share on other sites More sharing options...
PuppyDigs Posted January 2, 2007 Share Posted January 2, 2007 Metering default is always Evaluative. If that doen't tickle your pickle, you may enable CF 14.1, Averaging." However it also disabls auto fill flash reduction, so you'll have to roll your own via FEC. Sometimes the light’s all shining on me. Other times I can barely see. - Robert Hunter Link to comment Share on other sites More sharing options...
jim_larson1 Posted January 2, 2007 Share Posted January 2, 2007 ETTL uses the entire evaluative metering area. Metering is strongly biased by the focus point. CF14=1 disables the focus point bias. With CF14=0, it is important to use FEL to ensure that the focus point is over a neutral tone, which is seldom the case if you do not use FEL. ETTL-II uses the entire evaluative metering area, but the metering is UNAFFECTED by the focus point. CF14=1 turns off alot of other correction factors in the ETTL-II metering math.

jimstrutz Posted January 2, 2007 Share Posted January 2, 2007 For more information on Canon's E-TTL(II) system(s), start reading here: http://photonotes.org/articles/eos-flash/ I find E-TTL II on a 20D to be more consistent than E-TTL on a 10D, and CF#14=1 improves it even more.
