This is always an interesting subject to have..
Was having the discussion of Full Frame vs Crop with a friend that is about to jump for a 70d to a full frame (I shoot Nikon so I don't know)
And they where telling me I need to go full Frame (I have been looking at a Nikon D610 forever)
But Then It got me wondering.. Everything I shoot is indoor, based around people/models
With the odd bit of 'Landscape' when I go on road trips.
Even then, these pictures only ever end up on FB/Instagram with the rare few actually getting printed.
I just can't see the Benefit of going Full frame, unless i'm missing something quality/HDR wise?
Why did you end up going full frame?
If it is only for FB/instagram then why not just spend the money on a decent cropped sensor lens (or two)?
The cost of a full frame camera and then full frame lenses to go with it would be a expensive exercise just for facebook photos that are going to be resized smaller than crop sensor resolution anyway.
