What’s next from Canon?
- Thread starter Canon Rumors Guy
- Start date
No, just good old fashioned begging.
Me - do you guys do military discount?
B&H - only for active duty.
Me - so the Sailor who has been in two days gets a discount, but barnacles like me who did 30 years get nothing?
B&H - hold on one minute and let's see what we can do..
lol...

I was under the impression Canon officially discontinued the EF 400mm f/5.6 a while back.
Maybe not.
It is still listed at Canon USA's website, though it has been showing as out of stock there for forever.

It seems to me someone on a previous post here at Canon Rumors "wished" for a 70-135mm f/2 and ever since then there has been a small group that is vocal about why Canon hasn't yet mentioned a lens they think they were "promised."

Because it would still cost them several millions of additional dollars just in distribution and inventory costs when almost all of the 5D Mark V cameras they sell would probably have been R5 sales had the 5D Mark V not been created? What other company is producing a "5D Mark V" type of EF mount camera to compete with Canon that they would need to be concerned about protecting those lost sales?
Sure, for the few of us who would rather have an OVF 5D Mark V than an EVF R5, the lack of a 5D Mark V is disappointing. But Canon likely correctly assumes that there are not enough of us who would buy one to cover the additional cost of making and distributing/inventorying a 5D Mark V in addition to the R5. Or even if they could "break even" on the additional cost, the resources they would use to produce and sell a 5D Mark V could have probably given them higher returns if directed to developing other projects.

The size of the front element of wide angle lenses is driven more by how much vignetting can be tolerated, rather than by the effective aperture (entrance pupil) size.
There's a much greater difference between how much of the entrance pupil can be seen by all of the points in the field of view compared to how much of the entrance pupil can only be seen by some points within the field of view with wide angle lenses than with longer focal length lenses. It's also why the front elements of a wide angle APS-C only lens can be smaller than the front element of a FF lens with the same focal length and maximum aperture and not vignette more.
In many cases, the curvature of the front element of a very wide angle lens blocks light from one side of the field of view from falling on the opposite side of the front of the lens.

Technically, you cannot do what you suggest while shooting through the OVF. You have to have a separate AF module when using an OVF.

Being able to focus at narrower apertures in bright light does nothing for reducing subject motion in dimmer light, which is where much of sports is shot. You need dramatically better high ISO performance,on the order of the number of stops between f/2.8 and f/11, for that.
One reason the 7D and 7D Mark II, even with all of their shortcomings, were so popular is that they allowed one to shoot many field sports under lights at night or indoors in gyms with a $2,000 70-200/2.8 instead of requiring a $5,000 300/2.8 to get the same reach with a FF camera.
Circa 2016:
1D X Mark II + EF 300mm f/2.8 L IS II = $12,100 USD and one still needs another body + 70-200 for when the action gets closer.
7D Mark II + EF 70-200mm f/2.8 L IS II = $4,000 USD

IBIS is less effective as the field of view narrows. The sensor must move twice as far to compensate for the same amount of angular movement with a lens that has twice the focal length as another lens. The maximum allowable amount of sensor movement is limited by the size of the image circle, so...

Nor the ability to use the hot shoe for external flash control at the same time as the ability to have an eye-level viewfinder.

On the other hand, who is making an EF mount camera like what the 5D Mark V would be that can steal customers away from Canon if they don't produce a 5D Mark V? Most users who want a 5D Mark V will eventually "settle" for an R5. A lot really depends upon how good the improved EVF is for shooting sports/action.

Not physically possible. Though the EF-M registration distance is 18mm compared to the RF registration distance of 20mm, the smaller throat diameter of the EF-M mount leaves no room for the lugs of the RF mount that are more than 2mm thick to protrude past the EF-M flange.

You need to focus while seeing composing and seeing through the OVF, I think you agree with that. That means that the sensor is hidden by the mirror mechanism. So the light cannot hit the sensor, therefore you cannot focus using the sensor since it's not illuminated by light.
Sony tried the translucent mirror box, but well can't say it was a success. Could they have improved or did they decide not to bother because they dedicated themselves only to the A7 series, who knows...

Only if the AF performance and shutter life rating is better than the 90D and only if it has a built in viewfinder that the M6 Mark II lacks.

The mirror already is translucent. The AF module sits below the mirror box and there is second mirror behind the main one. Question just is can DPAF work with that amount of light.
