RF ultra wide lenses.

Canon RF 12-35mm f2.8L IS USM lens is an ideal super wide zoom lens which I think will be much welcome and preferred by the Advanced Pro. Photographers while it must be of the superseding quality to any existing super wide lenses and a RF 14-24 mm f4L USM will be a very suitable and affordable choice of Semi Pro. Photographers.

To my mind an RF10-30 mm f4L lens is very possible due to a smaller flange distance in the EOS R body.

A built in space for filter holder ring for polarising & Varriable ND filters in all the upcoming RF lenses is a great idea if Canon is really prepared to create that.

Any respectable comments are very welcome.
