I have a Canon EOS R and want to buy a a zoom lens, something like a 28-100 that has the Red Lens ring that will allow control of ISO.
is it more practical to buy an EF lens and a RING converter than an RF lens? I also have a T7 EOS that the lens could be used with, but that is not that important. I am just trying to save some money.
I want to use the lens for general photos of items that I appraise for individuals such a tools, equipment, fixtures, household items, collectibles etc.
I would appreciate suggestions and offers of lens for sale for my R. The R, according to my experience is difficult to change the ISO unless the lcd is opened and I prefer using the eye piece.
old fashioned I guess. I thank you in advance.
ALL RF Mount lenses have a control ring on them. Some have a separate control and manual focus ring. Other lenses have a combined manual focus and control ring with a switch on the lens. To set focus or control as needed by the user. Do you mean the RF 24-105mm F/4L IS USM lens or the RF 28-70mm F/2L IS USM lens. Canon hasn't made a 28-100mm lens in the RF Mount.
I agree on the EF lens, I should find a good RF lens. I am just looking for the most practical lens for my R. I do need a zoom and I do want the ability to change ISO and other settings from the ring....all suggestions are welcome.
Demetrius, I'd like to add some comments.
The red ring the OP is referencing is a distinction Canon uses to identify its "L" series lenses. This is a designation for Canon's professional lenses.
Demetrius has identified the best lens according to your criteria. RF 24-105 f4. This carries Canon's "L" designation and is in the FL 24~105mm. It has a constant aperture of f4 throughout its focal range. Its control ring can be assigned to change aperture on an R series body. It cannot be used on your T7. At this point, since you already have an R series body, and are looking for Control Ring programmability, I would not recommend investing in any more EF / EF-S lenses.

Yes I understand Rick that's why I didn't mention non-L in my post. I also know that ALL RF lenses feature a control ring that can programmed for anything such as aperture or ISO for instance. I also agree on you with NOT investing in older EF & EF-S lenses. No adapter is needed for native lenses and it cuts down on complexity if something fails.
