Keith over at Northlight Images points to a patent application that includes designs for superzooms so wide in range that they appear to be versions of the mythical lens that forum posters sometimes use as an example of unreasonable expectations.
A 33mm f/4 to 600mm f/7.2 lens might have previously been used as a tongue-in-cheek reference to an impossible design. Today, it is just one “embodiment” of a real patent application that also includes:
- 24-400mm f/4-6.5
- 24-300mm f/4-5.6
- 28-500mm f/4-7.2
- 30-600mm f/8
Another patent from a few days earlier shows a series of fixed aperture zooms:
- 200-500mm f/4
- 200-400mm f/4
- 300-800 f/8
The calculated aberration graphs included in the patents (example at left) show very significant distortion, and some detail-killing astigmatism and chromatic aberration.
The new patents show Shunji Iwamoto as the Canon inventor. Iwamoto has been responsible for many of the firm's recent zoom lens patents, appearing to specialize in designs that involve moving elements.
It'll be interesting to see if anything comes of these
100MP is nice ...where is my R5s ;-) :-)
By the way, for tilt/shift fans, I've agreed to do a free webinar (sponsored by BenQ) all about using tilt/shift lenses on the 22nd of Feb
I never expected that the RF14-35mm would have a 77mm filter thread for instance.
You can get a 50-1000mm EF lens today. Its Super 35 format which is close to APS-C.

If that's not enough, how about a18-1860 100X Broadcast lens for a 2/3 sensor.

Although one of those 28-infinity lenses looks pretty interesting as well. Depending on whether I can lift it.
The 300-800mm however might probably prove very popular with wildlife photographers, and F8 is a good compromise aperture that would allow fast shutter speeds and reasonable ISO settings. If they made such a lens, as a member of the budget family (RF 600mm F11 etc) for under £3000, I'd certainly be interested.
If it's affordable, light and doesn't have too much compromises in image quality (due to the very likely necessity of a lot of correction "in software"): It will be definitely on my list!
A 200-500mm f/4 is a "must-do" lense for Canon. I guess a lot of people are hoping for a 200-500mm F4 with a 1.4 built-in converter or a 2x converter. I personally hope it would be a 200-600mm lense.
I'd love to see a 300-700mm F8-11 consumer lense (or something similiar like F6.3 - F8) as a light superzoom built like the RF600mm/ 800mm F11.
How much is it in US dollars and is there a US sales site to purchase it?
I'm trying to figure how much it would cost with shipping from wherever this book sales site is...but no conversions on that site and won't tell shipping till you enter all your personal info...
Thanks in advance,
