Canon’s mirrorless megazooms, including Canon RF 120-700mm

New optical designs for Canon mirrorless megazoom lenses has been spotted online, including a monster Canon RF 100-700mm.

The pair of new formulas describe the Canon RF 100-600mm f/4.5-7.1 and Canon RF 100-700mm f/4.0-8.0 – which would seem to come from the same design ethos as the recently announced Canon RF 100-500mm f/4.5-7.1 L IS USM.

Indeed, the 100-600mm f/4.5-7.1 does seem to be a little too close for comfort to the 100-500mm f/4.5-7.1, so it is probably the case that this lens was ultimately replaced by the slightly shorter optic.

However, the 100-700mm f/4.0-8.0 is sufficiently different to – and arguably sufficiently more appealing than – the 100-500mm, so there may stons describe the lenses as follows:

Canon RF 100-600mm f/4.5-7.1
Focal length 103.00 248.50 600.00
F-number 4.60 5.85 6.80
Half angle of view 11.86 4.98 2.07
Image height 21.64 21.64 21.64
Total lens length 241.66 305.61 331.66
Back focus 17.57 37.01 97.33

 

RF 100-700mm f/4.0-8.0
Focal length 123.00 293.00 700.00
F-number 4.60 5.85 8.00
Half angle of view 9.98 4.22 1.77
Image height 21.64 21.64 21.64
Total lens length 246.28 322.64 370.48
Back focus 14.01 44.69 107.78

So, are these just remnants of the same design phase that ultimately birthed the Canon RF 100-500mm f/4.5-7.1 L lens? Or is there still a chance that we’ll see the 100-700mm appear in some form?

It’s entirely possible that this could be a non-L lens equivalent, perhaps envisioned to be paired with the Canon EOS RP or Canon EOS R6 (much like the Canon RF 24-240mm f/4-6.3 IS USM).

And, as with many Canon patents, they could just be designs that never see the light of day – though that 100-700 is something we would certainly love to see!
