I'm torn...having spent a long time putting together a good glass collection as I am a believer in the 'Glass First' philosophy it's about time I looked for a replacement body.
I currently have the original 5D that I bought when they first came out as I couldn't get on with the 1.6 crop factor of the 10D/20D bodies...I guess because I cut my teeth on the A1 & T90 back in the day.
I bought a 7D before a trip to see the last Shuttle launch in 2011 to gain some extra 'reach' but never really liked the pictures that came out of it compared to the 5D and have hardly touched it since.
There is something about pictures from the 5D that just does it for me...possibly due to the full frame sensor I think.
My ideal body would be the 5D MKIII but it is expensive and possibly due to be Canon's next replacement according to rumour so I am not keen on spending that sort of money only to have the latest & greatest announced within six months or so.
The 7D MKII looks nicely specced but of course is a crop and so probably not for me based upon my MKI experience although it has some lovely features.
That leaves the 6D (and 1DX of course) and so I was wondering how the 6D compares image wise with the original 5D?
I like the idea of having Wi-Fi built-in as I never could get the WFT-transmitters working reliably and in the case of other bodies except the 7D you still need to plug in cables to get it to work...even on the 7D II it would appear?
The apparent 'focus limitations' of the 5D never really hampered me and I have taken some great, in-focus pictures of fast moving jet aircraft etc. with little issue. In some instances the lack of complexity is better for me as it doesn't get in the way of taking the photo.
I am also not a 'machine gunner' type of guy preferring to wait for the moment instead of spray & pray. The thought of trawling through hundreds of photos looking for the one fills me with horror as does the thought of spending hours in PP although I do prefer to shoot RAW.
My interests are varied and cover most aspects of photography but macro, aircraft, still life & birds are my main focus although I would like to expand into portrait & try my hand at Motorsport.
I guess a 1DX should just about cover it then! 
I would be interested to hear of anybody who has been down this same path when looking for an upgrade to the 5D and ended up with a 6D.
How do they compare?
Thanks & kind regards,
