5700 är långsam:
Från start till den är redo för fotografering tar ca 5 sekunder och mellan bilder tar ca 2,5s.
7i:
Dimâge 7i är en mycket snabb kamera. Startar på ca 3 s. Mellan bilder så är tiden försumbar.
5700 saknar filtergänga, krävs adapter.
den saknar oxå manuell zoom, (vilket ger bättre känsla, kontroll och spar ström.)
5700 har 35-280mm, mindre vidvinkel men mer tele,
7i har 28-200mm
7i har betydligt fler intällningsmöjligheter.
5700 använder inte standardbatterier (R6) det gör 7i
intressanta fakta angående 7i vs 5700:
I found some timings on the reviews at
http://www.imaging-resource.com/ (for both cameras). They seem to support my tentative conclusions, with some important differences:
- AF is faster than I had predicted
The CP5700 was clocked 0.93 ... 1.09 sec (cf. the D7i at 0.63 ... 0.78). I figure these are "best case" times. (Phil clocked the D7i between 0.8 and 1.2; if the measuring system difference between the two reviewers is the same, this would put the CP5700 between 1.3 and 1.5 sec on his scale.) In any case, clearly too slow for sports or action photography.
- MF shutter lag is MUCH worse than I thought
The CP5700 clocked 0.655...0.755 sec, 0.223 with pre-focus (and metering); really bad compared to the D7i (0.22 s and 0.13 s respectively). IMO this is really bad: it means that you really have to lead a lot in order to compensate for the shutter lag, even when you have pre-focused and metered, and you'll get hardly any action frames at all without leaning on the shutter all the time (which will screw up metering if you point the camera in different directions, thereby changing the lighting of the subject). In my opinion, this renders the CP5700 just about useless for sports/action. Too bad; the 280mm tele + 1.5x teleconverter would have kicked ass for it otherwise
