Picky pikky pickee ... I've got a "D" and it AFs.

As to the Z converter, the "D" is shaft drive so
it would be MF-only on the converter.

Manual focus with digital indication when in focus. Not AF but better than trusting my old eyes

May be sooner than you think. This is the first global shutter that wasn't minuscule in size, and with fast fps rate also. APS-C 31.5 megapixels with 35 fps !

That was the reason I bought into AF in 1987 !

Too many long days endlessly shooting various
tech facilities in flat-lit fluorescent lighting was
fatiguing to my focusing abilities with regular
SLRs and wide-angle lenses that don't show a
whole lot of focus shift on the ground glass.

Altho the lenses for my new AF kit were acoarst
AF lenses, I used them in MF mode, cuz there
was no such thing as BBAF back then, and in a
"professional workflow" you can't let the AF leap
in and alter your focus while you're bracketing
your chromes or making "on-site duplicates". I
needed to shoot several identical frames of most
scenes and the single AF targeting point would
never be on the appropriate detail once the final
framing was adjusted.

Even tho the "Focus OK" light would light over a
few degrees of focus ring twisting, I could easily
judge the center of that range by touch, no need
to strain my tired eyes after working for several
in low contrast commercial interior lighting. Just
watch the green light while feeling for the center,
then re-frame for the shot ... or shots. So easy :-)

Where to look, on a Nikkor AF-D lens,
for the "D" indicator ... example is an
AF Nikkor 28-105/3.5-4.5D:

Some of the first AFs lenses also have a D imprinted on the lens. If it says AFs on the lens, it has a built in motor and should autofocus on the new cameras with the adapter. D doesn't refer to "drive shaft." It refers to the fact that there is a chip in the lens that gives Distance information for a flash. All lenses after those with the D on the barrel give this information, but they stopped putting D on the lenses. When people refer to AF-D lenses, they're referring to the second generation of Nikon autofocus lenses that do need the "drive shaft" and a motor in the camera for autofocus. With the exception of any lenses that say AFs and D, all of the lenses with a D imprinted on the barrel need the motor in the camera body.

For all those who still believe failures really never happen with single card slots and we are all making too much of this issue.

Tony and Chelsea Northrup were on new Canon sponsored and led EOS R shoot in Hawaii (with full production models), and were loving the video autofocus and vlogging UNTIL their single card corrupts and ends their shoot and loses all they had shot on the card. . They also talk about the reality of its 1.8X crop in 4K. Watch it all folks and make your own assessment about dual card slots and having fullframe capture of 4k. (Both Nikon Z-cameras and Sony A7 series and A9 cameras have fullframe 4k capture) .

Well, he WAS using a Lexar card... Still, this shows the value of dual card slots.

That said, I'm not impressed with the camera. The EOS R has too many video drawbacks to deal with. Yes, it has FANTASTIC AF for video bloggers (vloggers), but the 4k crop is a show stopper for serious independent filmmakers. If you're going to have roughly an m43 size crop, why not use m43 (GH5/GH5s) and get all its advanced audio and video advantages?

I agree that pros probably need the insurance of dual slots. What I algae wonder when someone says a card failed is, what caused it? If the camera caused the failure would the second card be spared?

My DSLRs have dual card slots that I divide between NEF and JPG. I never gave it much thought as a backup until all the uproar about the D7500.

I agree with you burkphoto.

Actually, I believe they had four cards fail - and a Canon professional there to witness it; he's probably still scratching his head.
