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.
