Hey gang, how big should that FF mirrorless grip be?

Answer with whatever assumptions about the flange distance you want, but remember that (I think) people will bolt heavy glass on it because we do stuff like that. But, again, that's your call.

It all boils down to what people want to do with it. I would expect a major market to be the landscape-backpacking fraternity and similar travelling light people.. so small and lightweight is key.

So if it isn't as small as possible, what's the point.. might as well get a 6D or an SL depending on what format you want.

About half the world agrees with you on 'the main point of mirrorless is to get smaller'.

The other half love what pulling the mirror can do to (someday) outperform SLRs, believe it or not. They have little interest in reducing size.

which markets though?

Sport?.. EVF is going to have to lag vs a mirror, even if it's only 40ms.. a combined mirror/EVF could be good though... raise the mirror once, then leave it there using the EVF while you shoot 25fps at full resolution.

Nature?.. sitting in a hide for hours on end using an EVF is going to kill those batteries.

Wedding?.. maybe, it could give accurate DOF but I don't see a huge leg up on live view.

what am I missing?

I'm on both sides of the fence.

For backpacking, I want the camera body to be no larger than the lens mount.

For indoor use I don't particularly care, as long as it has twice as many buttons as most people think it needs (e.g. an entire dial dedicated to custom settings, stuff like that.)

If the FF mirrorless is going to be a pro camera, it has to be built like a pro camera.

What I'm seeing is a thiner 5D3, with the rest of the dimensions about the same. If a 70-200 f/2.8 is your lens of choice, would you want any smaller? If you are shooting a Super Bowl or a World Cup, using Big Whites, would you want any smaller.

I should be big enough to accommodate a real battery!
Too many ML bodies are handicapped with tiny batteries when they could have been made slightly larger and carry a larger capacity battery.
Alternatively, a battery grip that works well.

FF mirrorless is only useful if you can use it with big apertures.
As you cannot change physics and the laws of optics the lenses will be almost the same size as they are now.
Thinking of the new 35L II, the 24-70L II, the 70 - 200L II or other quality lenses I say the grip should be at least as big as the one of the 70D. I voted for 5D3 because that's even better.

The body itself should be smaller and thinner, of course. But not the ergonomics. And I have no large hands.

To all those that want to travel as small and tiny and light as possible I'd ask:
- Can you bend the rays of light in other ways as we can today?
- Do you pack your body with lens dismounted to get advantage of a thin body?
- Even the smallest lens (EF 40/2.8 STM pancake) is almost as wide as the grip of my 5D3.
Do you believe in a FF telescope mechanism lens that's smaller and able to deliver better IQ?

My answer to all three questions is "No!"
So why make it as tiny as a M3? And all the EF-M lenses until now are for APS-C, so please don't compare.
There are better size/weight/IQ compromizes in the market than the idea of a Lilliputian FF with Lilliputian FF lenses.
That'll become reality the moment we can control gravity lenses. But by that time photography will look a little bit different than today ;)

I decided to make a crude grip size comparison. Enjoy my crummy tracing. As you can see there is not a lot of size difference in the actual grip width. Between an A7II and 6D. The original A7 was smaller. The difference comes in height.

For me I can get a full grip on a 6D. I tend to let my pinky finger fall off and sit on the bottom of the camera. For an A7II my pinky is always on the bottom and some of the time I let my index finger fall off onto the bottom. If a had a 5D III I would add that to the sketch but I do not. So I added a Rebel, Canon AE-1 and an Elan 7 for comparison.

I agree with ahansford but I don't think you are missing anything either ... I think there are two broad categories of reasons for wanting mirrorless:
1. you want small and light;
2. any other reason/s why you think mirrorless offers something better than a DSLR, eg EVF, faster sync speeds, etc. (I am unsure of how many of these things would actually require mirrorless as against have simply become associated with mirrorless, but let's leave that to one side for now.)

However, my view is if you are in the first group, you need to be looking at an APS-C (or even a m4/3 sensor), so you have lenses which are also small and light. I think what Canon has done with the EOS M line makes sense in that regard (whatever other criticisms may be leveled at other aspects of the EOS M line). If you are looking for small and light but also a FF sensor, I don't see how you are going to get it by the time you add a wide aperture lens, or a long lens, or perhaps even an UWA lens. At best, it seems to you might get something reasonably small and light if you limit yourself to lenses in the moderate wide angle to normal range - but I think that is a fairly serious limitation for many people, especially if you are shelling out a couple of thousand dollars for the camera body.

So, my thinking is if you want FF mirrorless you are probably in the second group. And so for people wanting FF mirrorless, I would have thought better to keep a body with at least a bit of size (I chose 6D size in the poll but I can see people wanting a range of sizes, eg if you are shooting superteles you probably want larger), so it's a better match for the size/weight of the lenses you are likely to use.

I'm sure there are people who will say they really do want FF mirrorless even though they are looking for small and light. I'm just not sure how realistic that really is. Perhaps there is a compromise though: say Canon made a mirrorless around the size of the SL1 (and perhaps lighter?) with an EF mount, with a view to it being used with lenses like the 40 2.8, the 24/28/35 IS lenses, the 50 1.8 STM and the 50 1.4. That would give people options, and in fact I can see quite a few people who own a 5D3 or similar also buying the mirrorless EF camera. All the lenses would be interchangeable so you could mix and match as you chose on any given day, but basically if you were happy shooting in the wide to normal lengths (and perhaps without very wide apertures) you could take your mirrorless EF + smaller lenses, and the rest of the time you would take your 5D3 or similar. I realise the flange distance issue would mean you wouldn't be using the smallest possible lenses on your mirrorless EF, but even so I reckon it could be pretty good. Plus it seems using a shorter flange distance may lead to increased vignetting on wider angle lenses, so keeping the EF flange distance may have advantages in making the mirrorless EF useful in a wider range of circumstances, so it might actually be a good compromise all around.
