Canon continues to develop optical formulas for an RF mount superzoom, something that we'll likely see sooner than later. This patent shows an optical formula for an RF 24-300mm f/4-5.6. It's hard to say if this is an L lens, as they tend to be larger than their non-L counterparts.
Canon RF 24-300mm f/4-5.6 embodiement:
- Focal length: 24.72mm 90.83mm 290.86mm
- F-number: 4.12 5.00 5.88
- Angle of view: 41.19° 13.40° 4.25°
- Image height: 21.64mm 21.64mm 21.64mm
- Total lens length: 165.57mm 210.57mm 255.57mm
- BF: 14.37mm 32.56mm 30.89mm
The 24-240 is fine when corrected. I can only imagine this new lens is much larger which makes it less of consumer zoom.
I haven't read the reviews of the RF 24-240mm and EF 28-300mm side by side, but IIRC the later's IQ justifies the 2.7x price difference. The later is an upgrade of the EF 35-350mm, so apparently it makes a profit, and might make one on RF as well.
My thoughts as well. This would be a great one lens solution for landscape photography when I have to lug gear for miles in a backpack.
I would love such a lens, but wonder what chances there for such a lens.
IIRC, the experts on this site explained there are physical obstacles to designing zooms that cross the normal from wide to tele. Possibly it's easier to design one for a MILC?
I would settle for an RF 15-70 f/4 (and an RF 100-400).
The 24-240 cost $500 as kit lens with RP and gets little use unless light is good and lens changing isn’t desired.
