I know you are a little harsh and you probably don't like Nikon, but this is not Nikon's first attempt at a mirror-less camera though not professional grade like the Sony A9, Nikon had the Nikon 1 V series (V1, V2 and V3) that were Mirror-less (I also own them). In an SLR mirror-less I believe Nikon (as well as Canon) are trying to compete in the Sony marketplace. It should be obvious by changing the lens mount and size (just like the Nikon 1 had their own lenses) that Nikon will not cater to the legacy equipment making a switch for those heavily invested in lenses very expensive. I for one will not purchase the new mirror-less Nikon full frame camera even if the make an adapter to fit old lenses to the new format.

Shorter flange-to-sensor distance requires less refraction... results in simpler lens designs, better wide angle performance, better actual light transmission (fewer elements required). Lens flaws are fewer, or easier to minimize.

Also, it’s 2018. Technology for lens design and manufacture is leaps ahead of where it was, just a decade ago. New lenses are designed to work seamlessly with the latest cameras, and will have the latest firmware-updatable electronics and the newest optical design improvements. Older lenses will lack features of newer ones, and may exhibit more flare, slower performance, and more of the various optical flaws such as coma, astigmatism, distortions, chromatic aberrations, flare... problems that get minimized with each new lens generation.

Just because you CAN mount a 1959 (or 1979) lens on a late-model camera doesn’t mean it’s more than an expedient compromise.

There WILL be adapters that work pretty well with recent lenses. And who knows? Canon or Nikon may just extend the flange distance and let you keep going with your same old stuff... but that would be the low road path. Fujifilm, Olympus, Panasonic and Sony already took the high road.

sounds good until you read the spec

Viewfinder type: None

That is a deal breaker, in bright light you can't see an lcd screen.

It's pretty much the same as my k5 but they left out the optical viewfinder, pretty much a cut down version.

I wouldn't want that camera for any more than the cost of the lens it came with.

Actually I have nothing against Nikon (or Canon), it's more the obnoxious questions that keep coming up about Pro grade Canikon FF mirrorless cameras. The FACT is neither one has one, but the RUMOR is that they will eventually. However, even when they release it, both companies will have a long way to go to even come close to matching what's on the market today (even those with smaller than FF sensors). The native lens mounts will be the biggest issue.

Canon may have it easier than most, lens control is totally electronic. You basically need to get the electronic signal from the mirrorless mount via an adapter so the body talks to the lens. That is the easy bit creating the evf interface and passing information to it, will be harder.

Mirrorless lens will not be restricted to current eos protocols as long as the body can tell the difference.

more tricky are lenses that use in body focus motors, probably would need to be in the adapter.

Canon already has the EF-M mount and an adapter that enables all existing EF mount lenses to be fully used. I'm not sure of the specs, though, in particular whether it would accommodate FF.

From my perspective, the main advantages of MILC are EVF and CDAF .... both require that light hit the sensor 'at all times', so they require being in LiveView mode.

I am sure that Nikon will not have their new mirrorless with the F mount. Canon might keep the EF mount but I doubt it. Canon switched to EF mount because there were significant problem with the FD mount when they moved to AF. The EF mount is now good except for the flange distance is too long for mirrorless but interfacing wise it's fine. Nikon F mount has a lot of incompatibility with body to lens interfacing so I am sure they won't keep it with the new mirrorless.

Thanks for the response Bill.

Nikon has already said they'll be using Z-mount, but right now all we know about it is the name. Canon has already introduced the EF-M mount for cameras such as the M-1 and M-50, but as I indicated above, I don't personally know whether it can handle FF or whether they'll find themselves supporting four mounts at some point.

Incidentally, I was at BestBuy this morning recycling a printer, so I stopped by their camera department. I was very much impressed by the M-50. If I were still a Canon user, I would consider it for my next upgrade if the price would come down a tad. I'm expecting the M-series to completely replace the 'Rebels' in a fairly short period of time.

I have no idea what you're talking about, the features in a camera don't have pretty much nothing to do, if it is a DSLR, or a mirrorless camera, they ARE mostly the same anyway!

I think your assumptions are accurate. Nikon’s always boasted about the ‘F’ mount going back to 1959, and how most older lenses work on their latest bodies. I found that to be complete hype.

None of my six pre-1985 Nikkors are an acceptable match for Nikon digital cameras. They mount, they focus manually to infinity, the aperture works, but they are a royal PITA because there’s no AF, and you’re stuck with limited metering and really crappy focusing screens. I no longer use film, but I’d rather load up the FTn or the F3 than put my older lenses on any digital Nikon. (Yes, even the Df.)

I’ve never seen much point in crippling the camera for the sake of lens compatibility. Canon did the right thing with EOS systems. It doesn’t bother me that I have a couple of FD lenses and an A1, either.

I agree that both companies came to late to market to make an impact in the mirror-less camera market and I am not sure that most of us owners of Nikon or Canon would switch to mirror-less if our investment in lenses are not compatible. They may not succeed if they can't get sales to come up to a reasonable level. I used to be a Sony photographer having the A700, A850, A900 A55 and A77, but about 6 years ago sold all the Sony gear and stayed with Nikon which I purchased the D2x in 2005, then the D7000 in 2008 and the D800 in 2010, and so on. I liked my Sony gear but could not afford to support 2 manufacturers.

That's exactly the marketing vs technology Catch-22 Canikon find themselves in. If they make it technically advanced, sales to existing customers might be lackluster. If they make it compatible with an old lens mount, sales to new users might be lackluster, and who knows how many existing customers will adopt the mirrorless bodies.

I suspect that few enthusiasts would switch to mirrorless and give up their investment in glass. Pros? Maybe.

It will be REALLY interesting to see what they do, and how well it works out for them. They should have started rapid development in 2012 or so.

Not FF. But thanks
