...for an (shooting for the moon now) EOS M-style body...with
*focusing abilities of, say, a 70D
and a sensor with...
*high ISO abilities of, say, a 5DMkIII
For those of you that haven't bought an 'M', it is a blast to use...really really fun.
But it DOES focus slower than even a low-level Rebel DSLR...and, at least in my hands, its sensor isn't so great as far as high ISO is concerned.
But I've thought about this a long time.
I would pay 1.5K for a 'tricked out' M, that worked as well as a modern DSLR works (as described above).
It should be obvious that I love my 'M', warts and all.
