One of the frustrations of shooting 4K on many of the recent DSLRs (particularly Canon) has been that the image is severely cropped. If new rumors are to be believed, however, the Canon 90D may feature 4K capture using the full APS-C sensor.
Canon Rumors posits that “we may be getting the new generation of Canon sensors with line skipping or pixel binning for video work.”
Previous rumors suggested the 4K video capture from a 32.5mp APS-C DPAF sensor. Full-width 4K capture on the APS-C sensor would be a very welcomed improvement for what may be the last of this prosumer breed of DSLRs. If this turns out to be true, I think the Canon 90D will sell like hotcakes at the rumored $1400 pricepoint.
I am in for an upgrade to 90D from my 80D, if they go with no crop with 4K and also DPAF (dual pixel auto-focus, not “contrast detect” as other 4K Canon cameras – such as RP and m50 in 4K mode) would be nice (hopefully they decide to do that, and not restrict it to protect their more expensive cameras – the R has DPAF in 4K), then this 90D camera would compete with the GH5 for usability. Also, hopefully overheating in 4K is solved with this version, if line skipping is used. One of the advantages of apsc is the smaller size lenses compared to FF. The 80D currently has a great Canon 18-135mm IS lens which is a long zoom for video in a modest lens size, and allows an attachment to the bottom of this lens which uses a push switch for smooth zooming (fast or slow speed) in camcorder style similar to rocker switch. This attachment is not available on FF Canon cameras. Hoping for a full featured 90D to buy!
