Nikon's Mirrorless Options | Sans Mirror | Thom Hogan Actually both GoPro derivates as well as DL havent been much of a success for Nikon. And "healthiest" camera market in this case just means: a market thats about stable, or not shrinking as fast as others. Canon EOS M sucks big time and isnt much of a commercial success either. And I dont see much of "experimentation" going on there. The native lens lineup for EOS M is barely functional at all. Was released with a normal zoom and a prime, took them ages to get a telephoto zoom, took them ages after to get a wide zoom, took them ages to get a macro. Now they have TWO superzooms, a ton of other zooms, and only two prime lenses, one of which is a very odd very short macro. ALL these lenses are rather dark and all zooms are plasticky. This is really not a great system. The only really good lens is the adapter to use Canon EF lenses. Complete nobrainer, use a new mount and adapter. You could but you obviously really shouldnt, because that would look stupid/ugly, would make for stupid ergonomics, and would needlessly waste space. Just make a damn adapter. Quite frankly I fail to see whats wrong with offering a mirrorless and a SLR option. Just make two great product lines and then let the people buy what they prefer to have. If Nikon finally drops the stupid Nikon 1 line, they should have enough development resources for that. SLRs and mirrorless both have their respective advantages. And I think many people would be happy to get ANY full frame mirrorless thats not superexpensive with an inferior sensor from Leica or these rather questionably built Sony FE cameras. Because one of the treats of such a camera is that you can adapt anything to them. Thus yes one could start off with a nice trinity of prime lenses (lets say 20/2.8, 35/2, 105/2.8 macro IS) and a Nikon F to Nikon XYZ adapter. I'm confused as to why this is much different to point 4. Optical viewfinders are also in the Fuji X-Pro line, theres nothing original about them. Pure optical viewfinders should be left to Leica due to their limitations (need to be calibrated, only really works with primes in the range of about 28-75mm, maybe a bit more if the optics can be switched, either way also doesnt work with close focus/macro).
