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:
|Half angle of view||11.86||4.98||2.07|
|Total lens length||241.66||305.61||331.66|
|Half angle of view||9.98||4.22||1.77|
|Total lens length||246.28||322.64||370.48|
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!
