Sony E body + Sony/Minolta A lens

COMPATIBLE MF MA AF AA

There are several adapter types available for NEX cameras.

Since this receptacle allows electric transmission, there are two types of adapters available: one with AF support and one without it. Simple mechanical converters tend to be very cheap, but obviously have less functions.

Sony offers adapters for its older A system lenses, called Sony LA-EA4. Interestingly, they are outfitted with a mirror and a focus shaft, which lends it a goofy look on an E-mount, but in return you'll be able to use Alpha and MAXXUM AF lenses' AF capability on NEX bodies. Available focus modes: AF-C, AF-A, AF-S, DMF, manual.

Despite its price, the LA-EA4 offers a lot of funcionality with flexibility and ease of use, and its zoom motor can operate the manual MAxxum lenses too.

There's a simpler adapter called LA-EA3, which has no mirror (therefore no pdAF focus shaft). Sony recommends this adapter for cameras with an integrated pdAF system (like the A7 or A6300). Using this ring connects the built-in zoom system of the camera with the A lock lens (except for SAM/SSM versions), allowing seamless transfer between the parts(however, only in AF-C, AF-S and manual modes). The best feature of these adapters that less light is being lost due to the lack of the mirror.

Terminology

In terms of compatibility, we distinguish four separate categories:

COMPATIBLE
PARTIALLY COMPATIBLE
COMPATIBLE IN THEORY
NOT COMPATIBLE
This means that you'll be able to apply the lens on the camera in question with a proper adapter, and full focus range will be available with it (often with aperture control too). If AF is supported, you'll see it in the description.
This means that due to the flange focal depth or other factor this conversion would be normally unfeasible, but with some compromises (e.g. using a speedbooster adapter) can be made possible.
This means that the flange focal depth should make mounting and using inifinty focus possible, but for some reason there are no adapter rings available or other factors make it unviable.
This means that you won't be able to mount your lens due to mechanical incompatibility or the difference in flange focal depth doesn't make inifinity focus possible. Although numerous lenses can be mounted on cameras without infinity focus, but this cannot be considered actual compatibility.

Additional information for compatible variations:

MF
AF
MA
AA
SB
MAC
TS
manual focus (on the lens, with its own control ring)
autofocus available (AF controlled by the camera body)
manual aperture control (on the lens, with its own control ring)
automatic aperture control (controlled by the camera body)
speedbooster (focal reducer) adapters are available
macro (variable length) adapters are available
tilt-shift (or other flexible) adapters can be used
