In my opinion, Sony has the worst and confusing lens naming system of all camera lens manufacturers. As a relatively new Sony a7 III owner myself having pre-ordered two a7 III bodies upon announcement, I did some research on whether or not I can use Sony E-mount lenses on my Sony a7 III. This is what I found:

Technically, you can use any Sony E-mount lens on your Sony a7, a7R, a7S and a9 models. However, using Sony E-mount lenses such as the ‘Sony Sonnar T* 24mm f/1.8 ZA for NEX’ will result in severe black vignetting around each image in full frame mode. This is because Sony E-mount lenses were specifically developed for APS-C camera sensors. The severe vignetting is a result of the lens not being able to cover a full frame sensor. To bypass this, you can enable the crop mode feature found on Sony Alpha 7 and Alpha 9 models. Using the same Sony Sonnar T* 24mm f/1.8  ZA lens as an example, in crop mode, the effective focal range would be 1.5x 24mm = 36mm and the resultant image would be down-sampled to a  lower megapixel output.

Confusing?

Yes. I agree.

In my rush to pick up a fast wide angle lens, I made the mistake of buying the Sony Sonnar T* 24mm f/1.8 ZA (SEL24F18Z) for my Sony a7 III. Clearly I did not take note of the “for NEX” in the product description before paying for it.

100% my mistake but seriously Sony, you guys could have differentiated FE and E-mount lenses a bit better.

This is what severe vignetting looks like

 

What lenses should you get for your Sony a7?

Don’t make my silly $998 mistake.

Always choose Sony FE for Sony E-mount lenses. Take a look at the screengrab of B&H when filtering for Sony lenses for your a7 or a9.

what sony e-mount lenses work with the sony a7

See how there is a checkbox for “Full Frame Lenses”?

Make sure that you click on that box, otherwise, you will be presented with a whole bunch of similarly named lenses that are designed specifically for APS-C cameras (e.g., a6300, a6500).

Do not buy these Sony E-mount lenses for your Sony a7

These lenses will either cause severe vignetting in your images or force you to use APS-C mode on your Sony a7 camera. Using APS-C mode will result in a loss of megapixel resolution. For example, on the a7 III with a 24-megapixel sensor, APS-C mode will result in a 10.66-megapixel image output.
