Coming back to this discussion, I watched a very interesting video by Matt Irwin this morning, not talking about if Nikon is dying or not, but rather showing why he is switching back to Nikon, while also taking a poke at other Youtube photo personalities who tout brands B, C or D as being better for X, Y or Z reason (this usually only lasts until the next, newest shiniest thing comes out), whereas Nikon take a long term approach.
Frankly, I think he makes some good points, and shows where the Nikon Z mount is a better solution and where Nikon is being more intelligent / using a long-term strategy.
After watching that, and discounting all the hype the other camera channels make about Sony (Fro et al), and taking a view of what I would use my next camera for, odds are I will be buying another Nikon in a few years, and most likely a Z.
So here's a dumb question.
Could either Canon or Nikon, with their larger diameter mirroless mounts, be considering sensor formats larger than traditional full-frame? 54mm/55mm are both larger than than necessary for a 36mm by 24mm sensor. 36mm by 24mm only requires an inner throat diameter of around 44mm, which explains the 44mm of the Nikon F-mount and the 48mm Canon FD-mount. Canon's EF-mount is 54mm, and likewise Canon's RF-mount and Nikon's Z-mount are 54mm and 55mm respectively. Could either of these companies be thinking about medium-format mirrorless? They could possibly get upwards of 45mm by 30mm assuming a 3:2 aspect ratio. Obviously this would require the lens to present an image circle large enough to fill such an oversized sensor, but given that the RF and Z systems respectively are no longer especially tightly coupled to legacy film formats, might this be the future?
It seems like if the goal were just to be full-frame, they wouldn't have to go much larger than the diameters of their DSLR mounts, much as Sony has with E-mount at 46.1mm.
That would certainly be nice and I’ve brought that up before but my guess is no, since the smaller Nikon mount is obviously big enough for FF, that means that Canon’s much larger mount diameter gave them the ability to go MF(FF+) 30 years ago and it never has.
Supposedly the larger diameters are strictly to give the lens/body interface more capacity to transfer more data back and forth. Faster lenses are possible too!
Flange distance would affect the sensor circle a small amount. I would be very pleasantly surprised if canon had built that capability to throw a bigger circle on the sensor into all the new ML lens line but I’m SURE mathematician types would have already made those calculations and let the cat out of the bag by now.
I’ve thought that very thing for MANY years but maybe the goal is simply to densify the pixels into the same area as small pixels get cleaner.
