After 40 years of shooting Nikon and now on m4/3 many of us are not waiting for Nikon to enter the DX/FX mirrorless market,we moved because of the size and weight of DX/FX taking its toll on our aged bodies, the lenses for such cameras would negate any benefits a smaller lighter body made.
If m4/3 users wanted FX/DX then Sony or Fuji would have been their destination (as it was/is at the moment) Nikon had a chance if they had continued to develop the 1 series to build customer confidence in the mirrorless camera side,yes it was not what most wanted but even those that felt the sensor was too small had admiration for the technology involved and the way it worked,to slowly start introducing DX then FX bodies from that base would have seen Nikon as a main player.
In normal Nikon fashion they ignored the main 1 series users that felt the V2 was a fantastic camera but needed a better sensor, they introduced a V3 with a better sensor but lacking the built in EVF,if that wasnt just a money grabbing situation and deliberate attempt to hinder 1 series sales i would like to know what it was about.
Now we go onto the AF performance of mirrorless cameras,i will be the first to agree it does not match D5/D500 ability in most cameras (jury still out on the latest Sony) and contrast AF alone never will,i now use Panasonic with DFD and you should not under estimate it in real world use,it will match or beat most middle to low end DSLRs and my camera body cost under £600.
At the moment i have a problem with my Leica 100-400 m4/3 lens (waiting for an exchange unit) my LCS did me a loan job of my choice from his second hand stock,i took a D7100 and 70-300afs not the latest but i had owned the D7200 prior to moving to m4/3 and never felt its AF was any better then the D7100,using the D7100 is like moving back in time my G80 and 100-400 wipes the floor with it for SAF and CAF.
This is not a knock Nikon post,its a feeling of how far out of touch Nikon are,yes users will buy a mirrorless D/X or FX but they will not wait for ever and Nikon have a hard job coming to market with something that would justify the wait.
After my last post i thought i had better put my money where my mouth is these where taken back from my flickr page for posting as since the latest ransomeware situation i dont keep any files on my interenet PC.
Perhaps a top end Nikon or Canon could have done better but most of us dont use them,so come on Nikon get in to the game.
