We have been following the rumors on the next version of the Canon 5D with some subdued but hopeful enthusiasm. However as many rumor sites now claim the final specs for the camera to be released next month; it is clear that there is a big disconnect in performance from the common DSLRs in the Canon line and the mirror-less competitors from Sony and Panasonic.
There is a lot to like in the camera specs but also a lot of disappointing things for the video enthusiast or professional. The camera has always been primarily a stills powerhouse and it is clear that this pedigree is maintained in the Mark 4. Auto Focus with dual pixel tracking support, pixel count and sensor should be heavily improved along with dynamic range as seen in the 80D and the impressive 1DX Mark II.
