Product Description
Lightweight, Precise & Bright
The lightest in its class and the brightest in Sigma's 50mm prime lineup, the 50mm f/1.2 DG DN Art Lens for Leica L-mount cameras is a well-designed lens for everyday use. Driven by Sigma's dual HLA (High-response Linear Actuator) motors, this lens delivers quiet and high-speed performance. Simultaneously, this focusing system allows for a more compact design, helping make this lens lighter than its counterparts. This classic focal length paired with an extremely wide f/1.2 maximum aperture allows users to effortlessly capture a variety of subject matter. Also, there are physical function buttons and switches that improve the lens's overall ease of use as well as its reliability in the field. To reduce ghosting and improve contrast, a super multilayer coating is used on the glass elements.
Impressively Smooth Bokeh
Sporting a f/1.2 maximum aperture, this 50mm prime lens provides rich and beautiful bokeh. Not only is this a massive benefit for creating more artistic and flattering imagery, but it allows you the ability to capture detailed images in harsh lighting conditions.
This lens's rounded 13-blade diaphragm is a first for Sigma and maintains a circular shape, helping create smooth and round bokeh even when stopped down.
Exceptional Build
Constructed with convenience in mind, the 50mm f/1.2 is equipped with multiple functions to assist you while shooting. An AFL button is available for maintaining focus on a single distance. Certain camera models allow for customizing the AFL's function.
The dust- and splash-resistant lens structure combined with the front lens element's water and oil-repellent coating create a durable overall lens that's reliable in the field.
The aperture ring is lockable and can be set to click/de-click depending on your preference.
Additional Benefits
- Lens construction: 17 elements in 12 groups
- Petal lens hood with locking mechanism
- Rounded 13-blade diaphragm
- Weight: 1.6 lb
- High refractive index glass and four aspherical lens elements
- Manual focus ring can be assigned to be linear or non-linear response on compatible L-mount cameras

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!”
