Sigma TC-2011 2.0X Teleconverter Lens - Leica L-Mount

The Sigma TC-2011 2.0X Teleconverter Lens is a teleconverter designed specifically for Leica L-Mount cameras. It provides 2x magnification, effectively doubling the focal length of your lens.

One of the key advantages of this teleconverter is that it maintains metering, autofocus, and optical stabilization (OS) functionality. This means you can still benefit from accurate exposure metering, fast and precise autofocus, and the use of optical stabilization when using the teleconverter with a compatible lens.

The teleconverter is designed to maintain the communication between the camera and lens, ensuring seamless integration and full functionality. This makes it convenient to use in various shooting situations where the extended reach of a teleconverter is desired.

It's important to note that using a teleconverter will reduce the maximum aperture of your lens. For example, a lens with an aperture of f/2.8 will effectively become f/5.6 when used with a 2x teleconverter. This reduction in maximum aperture may impact low-light performance and depth of field control.

Sigma TC-2011 2.0X Teleconverter Lens provides a convenient way to extend the reach of your Leica L-Mount lens without sacrificing key features like autofocus and metering. It's a great accessory for those who need to get closer to their subjects or require additional telephoto capabilities.

Product Features in Detail

Teleconverters designed exclusively for L-Mount lenses
The SIGMA TELE CONVERTER TC-1411 / TC-2011 are teleconverters designed exclusively for the use with SIGMA L-Mount lenses. Mounted between a lens and a camera body, the TC-1411 magnifies the focal length of the camera by 1.4x, and the TC-2011 by 2x.
The superior optical performance of the SIGMA Contemporary, Art and Sports lines of lenses is the result of efforts to pursue the highest levels of image quality. The SIGMA TELE CONVERTER TC-1411/TC-2011 upholds the image quality of the original lens to the utmost, while extending the focal length.
In addition, the new teleconverters have a dust- and splash-proof construction comparable to that of the Sports line lenses, and can withstand harsh outdoor shooting environments when combined with a dust- and splash-proof camera body and lens.
These lightweight and compact accessories are capable of single-handedly, providing an “ultra telephoto” angle of view for telephoto and macro lenses, while upgrading the performance of the original lenses; the SIGMA TELE CONVERTER TC-1411/TC-2011 will be a new special gear for users.

Outstanding optical performance
Remarkable optical performance enabled by the latest design to provide a high shooting ratio while upholding the high performance of the original lens.

A choice of 1.4x or 2x magnification factor
According to usage, two magnification factors to choose from.

Compatible with autofocus
AF is effective at all aperture and all focal lengths.

Dust- and splash-proof
Dust- and splash-proof construction comparable to that of the Sports line lenses.

Every single converter undergoes SIGMA's proprietary MTF measuring system "A1"
We used to measure lens performance with an MTF measuring system using conventional sensors. However, we’ve now developed our own proprietary MTF (modulation transfer function) measuring system (A1) using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections. The SIGMA TELE CONVERTER TC-1411 and TC-2011 will all be checked using this “A1” before they are shipped.

"Made in Japan" craftsmanship
All SIGMA’s manufacturing – right down to the molds and parts – is carried out under an integrated production system, entirely in Japan. We are now one of the very few manufacturers whose products are solely “made in Japan”. We like to think our products are somehow imbued with the essence of our homeland, blessed as it is with clean air and water, and focused, hard-working people. We pride ourselves on the authentic quality of SIGMA products, born of a marriage between highly attuned expertise and intelligent, advanced technology. Our sophisticated products have satisfied professionals and lovers of photography all over the world, because our manufacturing is based on genuine craftsmanship, underpinned by the passion and pride of our experts.
