What about lenses?
...but the whole TS-E 17/4 or 840/5.6 argument is largely moot with mirrorless options these days. Why?
My point, in keeping with the context of this thread, was that there are areas of the spectrum of photography equipment where Canon lags behind other manufacturers, and areas in which they are ahead. One area in which they are generally superior is lenses (RT flashes is another). Some people – including some who apparently don't even own Canon gear – seem quite willing to bash Canon's sensors, but give no credit in areas where they are the innovative leader.
BTW, have you spent some time shooting handheld with your 600/4 and an adapter-mounted MILC? I have, and it's an ergonomic nightmare. If you find it comfortable, great. If you haven't tried it, you should do so before suggesting adapters and MILC's render unique lenses moot (not to mention AF issues, because you went on to do just that, and 'hope that maybe the 5th incarnation will solve the problems', which the first four apparently failed to do).
Do you enjoy emberrasing and belittling and degrading people? Honestly, dude.
This place would be FAR more peaceful if you would just leave people alone. Regardless of how wrong they may be.
And I think we all need to back the hell off of people, and stop antagonism.
I don't know if it is simply ignorance here, or whether it is just conveniently forgetting,
You go right on making the forum a more peaceful place and stopping the antagonism. Calling me ignorant or deceitful is a great effort toward those laudable ends. Honestly, dude.
