Is Full Frame Possible for NEX7 or 9?

The Nikon F mount for 35mm film cameras had a 44mm throat diameter, the Sony E-mount is over 46mm. E-mount lenses could definitely be designed to perfectly cover full frame 35mm sensors (i.e. 24mm x 36mm sensors).

Note that the square root of ((24mm squared) plus (36mm squared)) is less than 44mm.

You cannot compare the mount diameter of a mirrorless system to a dlsr that has a longer flange distance.

You revived a thread started in 2010 and the last post was from 2013!!!!! Now you can only post after this if you were active on this forum in 2013!!! My rubber grip was starting to come of my NEX-7 around 2013 and the world was full of disbelievers of the mirrorless system. Look how many have come to the other side ;-)

How did you even come across this 8 year old thread to reply to it??

Google.

At least in my case. I was looking for Sony E mount diameter.

Given the design of the E mount NEX and its physical size, is it possible for the future NEX to accomodate a Full Frame design.

Personally, it would be such a dream come true if FF is possible.

You said it in your post: 'The Nikon F mount for 35mm FILM cameras'. The F mount and A mount were inherited from film and had to be made to work with digital. They do work but they vignette horribly.

Whaaaat?

They also work less than optimally with wideangle lenses. A lot of people don't seem to understand this - that a digital sensor is more unforgiving than film regarding the exit angle of light rays.

The NEX mount is as large as it is to account for telecentric digital lens design - ie to produce an imaging circle with perpendicular exit rays that strike the lenses of the edges of the sensor head on and so do not vignette, misfocuss and shift colour.

If Sony were designing a FF frame camera system from scratch today they would use a mount bigger than A mount for these reasons. The E mount is slightly smaller than the current A mount so OP there's your answer. Sony are not planning to do it.

Oopsie!

Kinda fun to read this thread :) (in a good positive way)

I give you a lot of credit for not hemming and hawing and just admitting you totally blew in saying Sony wouldn’t develop FF Cameras.

I wish more people were humble like that.

There is a lesson in this thread for everyone who tels us what Sony will and will not do, we are all guessing.

Why are you giving me credit? It was the mistake of someone else (RubberDials) who hasn't admitted anything.

Years have gone by and we now have Sony full-frame cameras. The FE mount has the same mechanical dimensions as the E mount. That's a 46.1 mm diameter for the mount but only a 43.6 mm diameter for the throat! Note that the diagonal of a full-frame sensor is 43.3 mm.

The claim that this would allow full-frame E [well, we now call them FE] lenses to "perfectly cover" full-frame sensor misses on two counts:

1. The actual throat diameter is only 43.6 mm: https://photographylife.com/nikon-z-vs-nikon-f

2. The rear lens element is never going to be as large as the throat diameter of the mount! The lens body needs to extend into the throat to engage the bayonet flanges and to reach the contacts. This cuts the maximum radius of the rear element by at least 4 mm, meaning a minimum 8 mm reduction in rear element diameter. Now a 43.6 mm diameter has been reduced to 35.6 mm or less. That works out to a minimum ray angle at the far corners of the sensor of 23.2 degrees. Not exactly perfect coverage!
