FE vs E mount?

Can someone in a few words explain the difference between the FE and E mounts? do they both work with A7s and a9? does one of the two give a cropped image? Are the best and newer lenses FE?

OK. E is to FE as DX is to FX.

Yes. But APS-C e-mount lenses are not referred to as E lenses. Only Full frame lenses are referred to as FE lenses, by default if it has no FE designation, its APS-C. To be honest it is a little confusing, especially now that Sony has almost entirely focused on FE lens production and bodies.

APS-C lenses are referred to as "E"

So we have FE and E lenses, both fit all E mount cameras. FE lenses work fine on APS-C cameras, whereas E lenses on FF cameras will auto-crop to APS-mode and use only part of the sensor.

This made me research on the beginnings of the E-mount.

"The E abbreviation of E-mount comes from the Eighteen mm flange focal distance"

en.m.wikipedia.org

Sony E-mount - Wikipedia

Interesting!

My first recollection of a Sony E-mount camera was one NEX, probably the NEX 6... Saw a guy holding one from his neck and I was impressed on how small it was... Compared to my heavier Nikon 7000!

After months of following these sony forums, i got an a7 then an a6000. :)

Still happy!
 
What is the difference between Sony a moment and Sony fe mount? I can't find anything on the internet that answers that question.

A mount are designed for DSLR / SLT cameras and have a longer flange register .

Fe mount are designed for E mount mirrorless cameras with a short flange.

FWIW, A-mount is the continuation of the Minolta mount, which Sony adopted and maintained after they acquired the camera division of Konica-Minolta. They still sell cameras lenses for A-mount.

When Sony set about creating their modern line of mirrorless cameras they needed a new mount (with much shorter flange distance, to suit cameras that don't have a mirror or prism) and that's when they introduced E-mount.

The FE designation simply refers to E-mount lenses that provide an image circle large enough to accommodate Full Frame sensors (hence the F prefix). Some manufacturers (e.g. Zeiss) omit the F even on their lenses that provide full-frame coverage.
 
I have a Sony A7r4 and wanted to buy the Sigma - Contemporary 16mm f/1.4 which is not FE mount but a E mount lens. I was wondering if anyone here has put this lens on a FE body (A7x/A9x) and how much vignetting I can expect?? I wish Sony made a wide angle under 20mm and f/1.4-f2.0 without costing a arm and a leg!

Thanks!

I can't answer your question about the image circle of the Sigma 16/1.4, as I don't own it.

However you might want to check out the Sigma 14mm f1.8, which is a FF lens and is available for Sony E-mount.

Meanwhile, there are rumours about a UWA prime from Sony possibly slated for release this year, but no confirmation or specs as yet...

This is the best explanation yet, thank you and everyone else!

... there is only an E mount.

The E mount cameras can be APS-C or Full Frame.

FE is used to nickname E-mount lenses that support a full-frame sensor.

e.g. SEL28F20 is nicknamed FE28, to describe it as a 28mm Full Frame lens for E-mount.

and SEL24F18Z is nicknames E24Z, to describe it as a 24mm APS-C lens for E-mount with Zeiss label.

So we have FE and E lenses, both fit all E mount cameras. FE lenses work fine on APS-C cameras, whereas E lenses on FF cameras will auto-crop to APS-mode and use only part of the sensor.

The E mount also has such a short flange distance that it can adapt almost all non E mount lenses, including SLR, DSLR and RF lenses, many with auto-focus solutions too.

Sorry if too many words...

It is a good explanation. Unfortunately, there is no name of clear way to see if a lens is APS-C only (like DX for Nikon or EF-S for Canon).

If it says FE, then you know it's full frame. This can be confusing for people who are unaware of the different sensor sizes and may buy a crop-sensor lens for their full frame camera without knowing it. Because of auto-crop, some may possibly not notice it at all.

It would be nice if Sony had done something to the naming to make it more obvious if something were an APS-C lens.

I own that lens and will try it on my A7Riii tomorrow.

Here you go:





The camera crops to the blue rectangle in APS-C mode, but the larger green rectangle is available if you shoot full-size and crop in post
