Sigma Launches Pre-Orders for MC-21 Mount Converter

Sigma has announced pricing and availability for its MC-21 Mount Converter. Pre-orders are now live via B&H Photo-Video for the EF-Mount version ($249) and the SA-Mount version ($169). Orders are expected to start shipping in April.

With the MC-21 Mount Converter, customers can use their Sigma SA mount and Sigma Canon EF mount interchangeable lenses with L-Mount mirrorless camera bodies. The converters are currently compatible with 29 lenses from Sigma. CLICK HERE for a full list of supported lenses.

Unfortunately, however, the converter will not be compatible with existing Leica L-Mount cameras. Likewise, there are some restrictions when using the converter with Panasonic LUMIX S1 and LUMIX S1R cameras. Here's a rundown of limitations with the LUMIX S1 and LUMIX S1R per Sigma:

Only AF-S works in Autofocus Mode. AF-C cannot be selected.
The Auto continuous operation cannot be used during video shooting.
Touch AF cannot be used.
With lenses incorporating MO (Manual Override), operation in manual mode is possible only after focusing.
MF guide is not available.
The image stabilization function inside the camera body and the lens cannot be used simultaneously. Please ensure only one of these is selected.
The AF Function Button and the Focus Preset Button incorporated on some lenses cannot be used.
