Is a native EF mount coming to a Canon full frame mirrorless camera? [CR1]

That's exactly the point. I was answering the claim that pros don't care about the mount.
If I have lenses much more expensive than any top pro Canon camera, why would I buy a new incompatible camera? I do care about compatibility and about the mount.

I missed the “if the mount is not EF compatible” but of your first post.

I expect if it’s not an EF mount, it will be easily adapted.

And that car is a Ford Raptor (drooling profusely). haha BTW: Probably going to be a classic one day. Gorgeous truck.

:) If they limit production it will be for sure.
So an advanced user doesn't want convenience? Sorry, I'm not buying that argument. 6D had wifi before 5D3, and people justified that with "that's a consumer feature". Now 5D4 has wifi. If it's just a "common consumer feature", why is it now in the 5D4? What changed?

The flip screen is just the latest example of that. People will say "pro shooters don't want that." All they have to do is never flip it out if they're so worried about it breaking.

I predict the next 1D will have a flip screen. And most people will be very glad it does.

What the common user may think of as convenience may not be necessary for the more experienced user.
The shooter at NBA game doesn't need the running man setting of a rebel. I am not sure he would need the flip screen.

I thought the same thing about features when I bought my 1D IV, it had less bells and whistles than the consumer models. But I found it didn't need them. At the time it had a superior AF system and a build quality to withstand adverse weather.

What's the lifespan of a lens? 15~20 years? How long does it take to fill out a complete/competitive lineup of lenses for a new mount? 15~20 years?

Does Canon have enough market share and manufacturing capacity to support more than 3 lens mounts? I think they do.

I'm actually arguing Canon goes with four mounts: EF, EF-X, EF-M, EF-S. And yes, they absolutely could handle that load.

My argument is that there is no big upside in rebuilding all of EF in EF-X for a lousy 1" savings -- you'd be climbing 'Whole lot o' nothing new' mountain for those 10-15 years as you clone EF for the new mount. That makes no sense. So keep EF-X to a handful of lenses that really make the sizing savings pop:

35 f/2.8
Likely a pancake
50 f/1.8
85 f/2
24-50 f/3.5 - 6.3
50mm f/2.8 compact macro (illuminated?)

And you call it good. You're done. Everything else requires the adaptor. EF reigns as the big tent that gets all the R&D support and EF-X, EF-S and EF-M are svelte little portfolios that cover their respective mounts.

5D5 = certain tilty-flippy, 100% happening

5DS2 = surely needs one so I wouldn't be surprised to see it, but I recall some commentary that the 5DS1 used 5D3 body componentry, so perhaps the 5DS2 is stuck with a 5D4 like fixed screen setup?

1DX3 = Canon may piss people off here and withhold it, claiming it wouldn't survive the tundra or jungle or desert if they offered a tilty-flippy.

The EF-M mount in itself is perfectly capable of full frame performance. However, none of the EF-M lenses produced to date would be capable of full frame coverage. The EF-M mount is simply the electronics, physical mount dimensions and flange focal distance. Which is the same flange focal distance which Sony is using in their full frame mirrorless. They may change the name to EF-FM, but the lenses mount in itself is the same. What will be the question is if you can use the APS-C EF-M line on the new FF camera and it has auto crop to aps-c mode.
Even Canon said that that mount isn’t good for FF. I wish people would stop thinking it is.

My issue is the possible loss of the optical viewfinder ... my old eyes don't do EVF all that well ...

With the optical I was able to add a diopter adjustment to suit my focus without glasses ...

A diaptor adjustment should be available for EVF. I had it on all my Video cameras going back into the 1980's, The M5 has a adjustment, I'm don't believe that add-on diopters from DSLR's fit. Certainly, a pro level model will have them.

I think Canon is smart enough to know that the number of buyers of 1DX hiking through the jungle is a fraction of the 1DX customer base. :D Dollars to donuts they have more buyers who are retired doctors and lawyers who can afford expensive toys than they do shooters roughing it on the Serengeti. Anecdotal, but I live in a city with a population of just under 200,000 people, and I've been at least once to all of the local photo clubs to see that's the camera of choice for the retired professional.

Of course, you could be right. A carefully crafted perception might be more important than reality.

P.S. Not trying to malign the retired docs. Some of them are really, really good amateur photogs, and take it very seriously. Intelligent, educated people tend to become good at whatever their passion leads them to.

Oh please no. I'd rather have no autofocus at all rather than auto focus only. Are there any current examples of lenses that are AF only from any manufacturer?

Canon has made some in the past, they may do it again.

My EF 35-80mm power zoom has only AF

I also had another one, but I don't have a photo. All were consumer lenses.

+1. I work with the ones who haven't retired yet in my day job. A mad intellect + a ceaseless engine to work hard + a battle-hardened sense of repetition/routine/algorithm and it's not surprising that a number of them have highly technical hobbies (including photography). I can't vouch for their creativity or eye, but their ability to juggle information in realtime figuratively resembles Tony Stark effortlessly processing all of his HUD inputs. I consider myself a bright engineer, but some of these guys are on another planet.

Now 1DM. No more 1DX,

Does Canon even dare to try such a camera in the first round of FF mirrorless?

I don't think so. I think they'll court the entry / mid level of FF users and see how the market shapes up, if FF segmentation like SLRs makes sense or if the market for mirrorless is differently structured, etc. All the while, they'll be working on throughput, shutter technology, AF and tracking improvements, rolling shutter reduction, etc. so that the second wave of FF mirrorless in a few years' time will have some 20+ fps superbeast of a 1-series mirrorless.

Don't get me wrong, a 1DXm or equivalent is surely coming -- but not anytime soon.

But think of all the lost vertical grip sales! :eek:

I kid.

Also, I think your trig is a little off there. 36 only works because 24 is in the picture -- it's an inscribed rectangle, right? So a square 36x36 wouldn't be covered by the EF image circle and all new lenses would be required.

The idea could work, but it would have to be a slightly different sized square sensor. Rough calcs on a piece of paper imply it would be more like 30x30 without increasing the image circle size.

I am not a mathematician and I'm lazy -- I took ½ the hypotenuse to be the radius of the circle. Then for each format, calculated the square area.
Probably not 100% correct! Thank you for looking.

I stopped by Best Buy the other week, and the guy who sold me the 6D2 last year was asking me about how I liked it. He later asked about my use of wifi on it, and I realized that I have never tried it. I do keep the GPS logging all the time the camera is on, probably more to see that the clock stays right. So far I haven't taken the camera more than 40 miles from home.

When traveling, I have used wifi on the G7X II, but that was mostly for getting the GPS readings off my phone. And on day-long bus tours, I'm hesitant to leave that on and be continually using up battery on both devices. If the pairing worked easier and more reliably, I could turn it off an on. But it is just easier to take a picture with the iPhone at the same spot and use the GPS reading from that to tell me where I was at the time.

On the 6D2 I have used an infrared remote one time when I needed a recent picture of myself. My wired remote for the Rebel won't work with it supposedly, so I have bought a wired remote for it, but haven't used it. I used the T3i one when I shot the solar eclipse.

Maybe some late afternoon I'll set the 6D2 up on the deck and try remote connection to my iPad to see if I can photograph the deer when they come around. They are skittish enough when I'm on the deck at all, and if I point something at them, they duck into the woods.

The radius of the circle should be right. The problem comes in switching to area. Inscribing a square would mean that the diameter of the circle becomes the diagonal of the square. So each side of the square would be about sqrt((43^2)/2) if I haven't messed up my notation, or 30ish as mentioned above.

The crude and non-mathy way:

1) Draw a circle. (This is all the real estate your EF lens can reel in.)
2) Draw a rectangle (3:2-ish, doesn't have to be perfect to make this point) that has all four corners touching the circle.
3) Now change the shape of that rectangle to a square that still must touch the circle in all four corners.

There is no way to do that without the long side of the rectangle getting shorter.

I had no idea! Well, I guess there must have at some point been market space for a product like that, maybe there still is. How did it perform for you? I feel like this would drive me mad if I couldn't quite get the focus right.

Having relatively recently bought the 1DX2 I could hardly justify a repeat but all I can say is give me all the best features of mirrorless and DSLR and I'll be hard pressed to restrain myself from one last body purchase. Must have full EF capability.
