3. exposure hold (options to enable not to timeout as long as new exposure is choosen). i believe that with this option, i would probably moving faster than now in Av and Tv mode. for now, i have to use manual mode all the time since exposure would be canceled during the time that i am playing around with focus point(s)
the AE lock holds for 4 seconds on the 7D. I do believe that it will lock continuously so long as you press the button at least once every 4 seconds, though i have not tested this as i do not use this feature often.
that is what i thought, but there is an option of exposure hold offered in canon 7d (not sure exactly what this does (not playing around with this option that much since i found out that it is also timed out. i prefer there is an option to hold it until i am going to cancel it or choose another exposure.
it is kinda slow when choosing focus point and keep track exposure at the same time. however, there is a work around in this case (i do not like it but having no choice as if i am choosing to shoot in Av or Tv) which i have haft press shutter again prior to choosen exposure time out.
as current rumor specs of 7d mark ii, it is a great config, in fact i am loving it already
not sure how noise at high iso turn out.
note: if canon can help me to put this option into my 5d mark iii, i would love my canon gears more
