EOS-M / Re: FF EOS-M?
« on: June 09, 2013, 06:30:16 AM »
Hello together,
my opinion is very good representated by a comparison of EOS 100D and EOS M. Both systems are physically optimized for APS-C-sensor, so you can interpolate e.g. to an hypothetical FF-M and the 6D as a rel. small FF-DSLR.
What's the difference?
EOS-M is only slightly smaller then the EOS 100D, if you apply a fast lens or a longer zoom. EOS-M because you must choice a EOS-Lens + Adapter, but even if Canon introduces longer M-Lenses with faster design, I'm noit shure if we will see this, the advantage "weight" ans "outer dimensions" are gone. No optical viewer is the next point, solvable with electronic means, but this moment there is none. The autofocus issue is to solve, next firmware will improve it shurely.
FF-Lenses will due to the physical facte be larger, even with a shorter mount-dimension, so the advantage of smaller dimensions will not be as significant as perhaps estimated. The advantages of the missing mirror and perhaps the missing mechanical shutter - permanent availiability of sensor-data for metering and autofokus - are not consequently used today.
Therefor for serious use I postulate some things which have to be happened until a Replacement of the mirror makes seriously sense:
- adequate electronic wysiwig-viewfinder
- permanent autofokus in the quality of the actual systems, incl. sensitivity under low ligh
- compatibility-bridge to the existing system
- new body-desing to bring serious advantage to the user.
