Product Description
An ultrawide Leica L-mount prime, the Sigma 20mm f/1.4 DG DN Art Lens offers incredible imaging performance from corner to corner, with a large maximum aperture that makes it ideal for use in low-light environments, particularly under dark skies where its new features are especially useful. Always an excellent choice for landscape and architecture, this lens is equipped with newly updated functions especially useful for astrophotographers.
Combining an optical design with in-camera corrections that keep distortion under control, this lens offers an extremely well-controlled sagittal coma flare that yields pin-point stars from edge to edge. Additionally, a new Manual Focus Lock (MFL) switch disables the focus ring, ensuring that focus never changes, even after hours of shooting under chilly, dark skies. The lens has also been developed to accept 82mm front filters, a rarity on ultrawide primes, and another unique feature includes a rear filter holder, which accommodates sheet filters for various creative effects.
- As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
- Prime wide-angle 20mm f/1.4 lens is designed for full-frame format Leica L-mount mirrorless cameras and can also be used with APS-C models where it provides a 30mm equivalent focal length.
- Fast f/1.4 maximum aperture is well-suited for working in low-light conditions and provides greater control over the focus position when using shallow depth of field techniques.
- Two SLD and three aspherical elements have been incorporated within the lens design to correct for chromatic aberrations throughout the entire focusing range and to ensure exceptional clarity and contrast. This optical design also helps to control distortion and limit vignetting.
- Employs a concave double-sided aspherical element, which provides outstanding edge-to-edge sharpness and optical performance.
- Optimized for astrophotography, the lens offers extremely well-controlled sagittal coma flare and limits ghosting.
- A Super Multilayer Coating has been applied to lens elements to minimize lens flare while producing contrast-rich and color-neutral imagery, even in backlit conditions.
- Inner focus system powered by precise STM stepping motor provides high-speed autofocus and near-silent operation.
- Optimized for astrophotography, a new MFL (Manual Focus Lock) switch disables the focus ring, ensuring that focus never changes, even after hours of shooting under chilly, dark skies.
- Aperture ring with click switch and lock switch prevents accidental aperture changes.
- A rounded eleven-blade diaphragm helps to produce an attractive out-of-focus quality.
- Petal-shaped lens hood helps to reduce lens flare when working in strong lighting conditions and offers some protection to the front element of the lens.
- 82mm front filter threads and rear filter holder for sheet-type filters.
- Curved lip at the front of the lens keeps an optional lens heater from slipping in front of the lens.
- Brass bayonet mount for ensured precision and durability.
- Compatible with optional UD-11 USB Dock for Leica L, which enables fine-tuning different lens characteristics and updating its firmware.

Ordered a lens on Friday. Item was delivered to me on Monday. Arrived in excellent condition in perfect working order. Not only did I pay a very reasonable price, but the shipping was free ! I will definitely do business with Pixel Connection again should the need arise !
I cannot say enough good things about Pixel Connection. I've bought multiple camera bodies - new and used - from them, along with several lenses, and they simply cannot be beat. Super helpful on the phone, good prices, and willing to work with customers to make the right solution happen. Pixel Connection is where I look first when buying camera equipment.
I am a cosmetic dentist so my photography is very important to me. I needed my camera set up for ease of use and custom settings. Jesse and Sam are so knowledgeable. Those two men helped me quickly and the Pixel store is open until 7 pm so I was able to get this done before my next working day! I also noticed Pixel has everything one needs for cameras, video and audio, social media, drones and even film! Check this store out for yourself for quality service and products!
⭐⭐⭐⭐⭐
My latest experience with ThePixelConnection was absolutely phenomenal. Matt and Ari went above and beyond to ensure I got the camera I needed, even when it seemed impossible.
The item I needed was out of stock everywhere else, but they didn’t stop there—they took the extra step to contact the manufacturer directly and managed to secure a new unit straight from the factory. Thanks to their incredible effort, I received my camera just in time for an important event.
What truly sets ThePixelConnection apart is the personal touch they bring to every interaction. Unlike my experiences with B&H—which, while efficient and resourceful, often feel very clinical and transactional—ThePixelConnection makes you feel like a genuinely valued customer.
I’ve worked with B&H for years and spent a small fortune with them, but if ThePixelConnection has what I need, they’re always my first choice. Their team is passionate, knowledgeable, and deeply committed to ensuring you get exactly what you’re looking for.
Matt, in particular, is a seasoned professional with extensive expertise in photography and their product lineup. His guidance and dedication made the entire process effortless and stress-free.
If you’re looking for exceptional service from a team that truly values its customers, look no further than ThePixelConnection. They’ve earned my loyalty, and I can’t recommend them highly enough!

“Quick and easy and with the option for in-store pickup.”

“I have pre-ordered two cameras with Pixel Connection and both times have been wonderful experiences. Staff have been kind and helpful both times. They provided updates weekly and even provided me an option to purchase a different color camera when it became available before my pre-ordered color. They were also prompt with their shipping once payment was completed!”
