I don't think you can separate viewfinder preferences from camera preferences, so I would rate the utility of such versatility as only slightly higher than equipping cameras with towel racks.
You can see from my signature (and you probably know from my posts) that I shoot DSLR (Pentax APS-C), Sony A-mount SLT, and Sony E-mount. Mostly, I shoot with my DSLRs, as I prefer the OVF for general shooting. BUT... there can be significant advantages to the EVFs in my SLT and mirrorless cameras in certain use cases... specifically, optional amplified view in lower light (darker conditions, same brightness), DOF preview with no loss of brightness, live histogram, the ability to use either focus peaking or magnification to support
perfectly accurate manual focusing, stabilised view (because the EVF image is taken from the stabilised sensor), shooting crop with the cropped area expanded to fill the viewfinder, amongst others (for instance, how about shooting B&W with the viewfinder rendering in monochrome?). So, whilst I genuinely prefer a good OVF, there are plenty of occasions when - for
me - an EVF can be very useful indeed. And, respectfully, I don't agree with folks who claim Live View on the rear LCD screen, with or without a loupe, offers a comparable experience. It's not bad at all, but it's really not as good.
If it releases the new OVF adapter, with just one camera Canon will be able to offer:
- Shooting native R-mount lenses via the EVF
- Shooting adapted manual rangefinder and SLR lenses via the EVF (using inexpensive dumb adapters)
- Shooting adapted, electronically connected EF SLR / DSLR lenses via the EVF (using the existing "straight through" EF to R-mount adapter)
- Shooting adapted, electronically connected EF SLR / DSLR lenses via an OVF with full DSLR-like experience (using the new EF to R-mount OVF adapter)
I can see a market for this. And it's a clever move by Canon, IMHO, as it allows them to concentrate on mirrorless development - even at some point, perhaps, to cease DSLR development, because with the new adapter fitted, the camera will actually be a full DSLR. Plus, it eases the transition for Canon's DSLR customers into the R-mount mirrorless platform - folks who, currently, might be staunchly opposed to mirrorless.
If it's not for you, if you see no value proposition, I respect that. But that's not how I see it...
