Ready for the Canon RF 70-200mm f/2.8L IS USM Z?
- Thread starter Canon Rumors
- Start date
Back in the day…all Canon’s had an “A” button on the Aperture ring on the FD mount. Things seem to be coming around again.

I'm skeptical about claims that being able to use an extender on a 70-200mm is necessary. I tried extenders on the EF versions of them, out of curiosity, and I thought the benefits were barely visible, so to speak, once IQ was factored in.
I understand the desire to use extenders on the 100-500mm and longer lenses. I thought it a bit disappointing that Canon's extenders didn't allow full zooming on the RF 100-500mm.
Hope it works out better with the new 70-200mm.

And yet... all previous 70-200/2.8 zooms have been 77mm ie there is no precedent or technical need for the change unless... it is a f2

The EF 70-200/2.8 III has 1.5 stops of vignetting, the RF 70-200/2.8 has 3 stops.And yet... all previous 70-200/2.8 zooms have been 77mm ie there is no precedent or technical need for the change unless... it is a f2

There is precedent: Canon has slowly moved the f/2.8 pro zooms from 77 to 82 over the last couple generations of lens redesigns.And yet... all previous 70-200/2.8 zooms have been 77mm ie there is no precedent or technical need for the change unless... it is a f2
The change happened with the EF 16-35mm Mk II in 2007 and the EF 24-70mm Mk II in 2012, and the 70-200/2.8 is the only one left on 77mm. Would make sense for those who want to standardize filter sizes, and not have to worry about either (a) carrying two sets, or (b) making a choice of either using the lens hood or a filter step-up ring.
A 70-200 f/2 will likely require the same size filters as the 100-300/2.8 (112mm).

I do, frequently. When shooting events, I often switch between wanting to isolate one subject and having a group in focus. I have aperture on the main dial.

Aperture priority is my setting for any still, non-moving subject. So, don't need a dial on the lens, as I only need the one on the camera. In the rare times I use manual, also only need a dial on the camera to change aperture. They took the aperture ring off the lens 40 years ago, so I find it extremely funny that people are complaining about it not functioning.

The IQ from the EF 70-200mm f2.8 III LIS is exceptional. The MFT charts certainly show this and it’s seen in real world shooting. With a 1.4x TC (Canon give MFT’s for each teleconverter), the EF 70-200 f2.8 III L IS is still sharper than the RF 100-500 LIS. Even at wide open apertures. however , things deteriorate with the 2x TC. I find I need at least 2/3rds of a stop down to bring the sharpness back to an acceptable level. Plus the fact that the lens is just getting too heavy, unbalanced and bulky to be useable.

So far I've only seen the R50 marketed at vloggers and streamers, mostly using the kits that have camera, lens, mic and lights. Maybe the success of the ZV-E10 will make Canon consider an EVF-less model

I do it all the time in landscape photography. Sometimes I want mostly everything in focus so I'm shooting f/8 to f/11, but other times I want depth of field to get your eye to "zoom in" to a particular focal point which brings depth to the image. But sometimes I see multiple compositions of the same area, so I switch apertures to get those various compositions. Also if you're hiking on trails, you might take a close/macro shot on the trail itself, and then take a photo of a vista. So yes, it's not uncommon to change aperture on the fly; it's actually uncommon for me to leave it the same for a single session.
I used to shoot Fuji and loved the aperture ring. It's a tactile dedicated control close to the camera body that reduces the amount of arm movement - getting to the front control wheel on a lens always requires me to move my hand from the body where it was stabilizing. If my hand is already pretty close to where an aperture ring would be, I'd love to have a ring there.

Good point but would it be reasonable for the optical design to be restricted by the 77mm filter thread?
Surely the vignetting would be due to other factors especially as it was announced at the same time as the RF15-35/2.8 and RF24-70/2.8

Do you know someone who has had this happen or are you just worried about the risk? I have the current version (RF 70-200 2.8) and haven't had any issues with it yet.

That's my experience as well. The 1.4x TC works really well on all the telephoto lenses I've tried it on (70-200/2.8 II, 300/2.8 II, 200-400/4), whereas the 2x TC only works well on the 300/2.8 II.

The collar comes with a manual, the reports I’ve seen on the interwebs were all by people not following the manual.
That makes it a bad design, not untrustworthy.
