Sigma's MC-11: Sigma lenses on Sony E cameras

Which Sony APS-C cameras

Sigma checked that the cameras on its list work in general; it does not guarantee every function or how well it performs. Sigma's camera list (PDF)

Which lenses

Every lens on Sigma's list autofocuses in AF-S and none in AF-C or AF-A. DC lenses are made for APS-C cameras and DG lenses for full frame; on these cameras both frame 1.5 times their focal length.

DMF lets you turn the focus ring after autofocus has found focus. Sigma lists it for 21 of the 29 lenses; to use it, a setting in the lens is first switched on with Sigma's USB Dock (sold separately) and Sigma's free Optimization Pro software. Sigma's lens list (PDF)

What carries across

• Autofocus in single-shot AF (AF-S).
• Stabilisation in OS lenses, working together with the camera's own on cameras that have it.
• Automatic exposure: the camera sets the aperture.
• The camera's corrections for shading at the corners, colour fringing and distortion.
• The lens data in each file: the lens, its focal length and the f-number.

What does not

• Continuous AF (AF-C) and automatic AF (AF-A).
• Autofocus in video: Sigma says to focus by hand when filming.
• Teleconverters: the MC-11 takes none.
• Lenses not on Sigma's list, Canon's own EF lenses included: Sigma does not guarantee them, and some lenses do not physically fit the adapter.

The light on the adapter

For about 3 seconds after you switch the camera on, a light on the MC-11 says whether it supports the lens:

• Green: the lens is supported.
• Green, blinking once a second: supported, but the lens's own firmware needs an update through Sigma's USB Dock.
• Orange, blinking twice a second: supported, but the MC-11 needs an update to hold the lens's data.
• No light: the lens is not supported.

Updating it

Sigma adds lenses to the MC-11 through updates: connect it to an online computer with the USB cable that comes with it and run Sigma's free Optimization Pro software. A lens's own firmware is updated through Sigma's USB Dock.

Size and weight

The MC-11 weighs 125 g and is 69.4 mm across and 26 mm long. Sigma's manual gives these figures for the SA-E version, and Sigma UK gives the same weight for both. Sigma UK's page · Sigma's manual (PDF)
