Need user info on Canon 200/2.8 EF (USM II) lens

Would like to adapt this lens to Nikon Z and was wondering if the "F-stop ring" (closest to camera) actually adjusts the F-stops or it's there just to mount the lens ?

There are several adapters on the market, so that's not an issue.  Thanks.

Don't know what you mean by "F-stop ring" but I don't see any aperture control.

Thanks for getting back.

Many lenses have the ring (indicated) to adjust the F-stops manually....tho I have no idea if this is the case with this particular lens (or not).  That's why I'm asking, since THAT would make a difference.  Or perhaps I have to get an adapter that can do this via the camera (electronically).

Check my original post from the instruction manual and you'll see that that red arrow doesn't point to anything meaningful.

Basing on my prev knowledge the ring to the right clearly indicates aperture change.  Some lenses ( I happen to have one too) have the ring and no visual indicators.

The manual (pic you provided) for the Canon 200/2.8 does not clearly indicate the function for the ring (R. side).....and only people who used the lens would know it.  THIS was the reason I asked.  By the way just about all the legacy lenses (Nikon) have this sort of aperture adjusting ring.

OK, maybe I'm bit retro with all these manual optics, but the older Canon lenses were v. similar.

The lens you picture is not the lens you asked about.

True.  I showed you an example what the ring has been used for many years, in fact on Canon lenses as well.  Granted, perhaps not in the recent years.

It's just a grip to make it easier to mount the lens.  No Canon made EF or EF-s lens has ever had a mechanical aperture ring.

Commlite, Fringer Techart and Viltrox (possibly others) all make £200-ish electronic mount adapters to put EF lenses onto Nikon Z.  They have to be electronic and translate the protocols in order to adjust the aperture.  The plus side of this is that every EF lens made in the last 35 years should AF on Z mount, even though Nikon AF and AF-D lenses won't.

Thanks all for responding.  While we were asleep Canon (tech) answered my question.  True, the ring close to the camera is NOT adjustable as to aperture....that was my initial question.

Since I shoot manually I was under the impression that any elect. contacts were not needed and I could adjust the aperture just like I did in the film days - not so.  I'm aware that there are adapters with contacts.....and that itself becomes a problem for some, since the "appropriate" contacts did not work - all one has to do is read some of the reviews.  In short, I'm trying to eliminate those issues from day one (if possible).

As stated, AF did not enter this plateau, but having appropriate contacts (one can hope) will allow me to adjust the aperture.

Initially I thought of Nikkor 180/2.8.  This lens will fit, no doubt, by using FTZ adapter and it WILL WORK.  Having the aperture adjustment I can use optics even from 45yrs ago+ (50mm F1.4 AIS or the famous 105mm F2.5+++).  Granted (it's visual), I might be off by 1/2-1 F-stop, which can be tweaked in the edit.....till I get totally proficient.  Anyway, I needed a lens that fits with my new 24-120S.....and considering Nikon future plan, I can't see the manuf come up with anything close to that focal length.....nor I wished to go the 70-200 route.....so the Canon 200mm became a bit of an obsession.  Bit convoluted, but there you have it.  Again thanks.

I use the version I of this lens on my GFX100s. Works really good. I can control aperture manually through the Fringer Pro adapter or through my camera.
