- The only difference between the A2 and A2E is the eye-controlled
- focusing.
-
- If you wear glasses, you may find that the eye-controlled focusing
- doesn't work well for you. (At least it doesn't for me, so I haven't
- felt compelled to get an A2E. Astigmatism and contact lenses just
- don't go together that well.) So, it's best to try it out yourself
- before buying into this feature.
-
- In the event that the eye-controlled focus works for you, there are
- still a few things to consider:
-
- 1) The "usual" way of getting a shot is to focus first and then
- compose. The A2/E prefer that you do this in the opposite order. That
- is, compose and *then* focus. Because the exposure/flash metering is
- biased towards the active focusing point, focusing and recomposing may
- throw the metering algorithm off a bit.
-
- 2) The "peripheral" AF points are detect only horizontal detail. So
- it is preferable to have subjects with horizontal detail. One can
- still compensate by tilting the camera. (I do this for my EOS 630 when
- I get no vertical detail since my AF sensor is horizontal.)
-
- 3) Eye-controlled focus may save you in those situations where there
- simply isn't time to recompose. (I know I could have used it last
- week... Arg.)
-
- If eye-controlled focus works for you, and you can get used to the
- different order of events, I think it has a lot of potential.
-
- Hopefully some EOS A2E/5 users can describe the adjustment period (if
- any).
