SIGMA

Sigma 45mm f/2.8 DG Contemporary L Mount Black camera lens

SKU CH-JX8Y-XMHRS

Compact 45mm f/2.8 prime lens for L Mount mirrorless cameras, weighing 215g with smooth 7-blade bokeh and fast autofocus

  • Superb clarity from 45mm f/2.8 optics
  • Smooth circular bokeh via 7 rounded blades
  • Ultra-portable at 215g and 2.5x1.8in
  • Fast accurate autofocus for sharp action shots
  • Full-frame I-series design built for mirrorless systems

Compact Prime for L Mount

The Sigma 45mm f/2.8 DG Contemporary is a full-frame compatible prime lens built for L Mount mirrorless cameras. It delivers a classic normal field of view with a bright f/2.8 maximum aperture. Weighing 215g and measuring 2.5 x 1.8 inches, it is designed to match the compact form factor of modern mirrorless bodies.

Upgrade from Kit Zooms

This lens replaces variable-aperture kit zooms with a fixed f/2.8 aperture across the frame. The jump is worth it when you want shallower depth of field, better low-light capability and sharper edge-to-edge rendering. Seven rounded diaphragm blades produce smooth circular bokeh for subject isolation.

Suited for Everyday and Travel Shooters

Photographers who value a light, unobtrusive prime for street, documentary or daily carry will appreciate the fast autofocus and high optical quality. Buyers who need zoom flexibility, a wider maximum aperture or longer focal lengths should look at other options.

Questions about this item

What are the physical dimensions of this 45mm f/2.8 lens for L Mount?

The lens measures 2.5 inches in length and 1.8 inches in diameter, weighing 215g (7.6 oz). Its compact barrel is designed to balance well on L Mount mirrorless bodies.

How is the lens mounted on an L Mount camera, and what step is often missed?

Align the red dot on the lens barrel with the mount index on the camera, then twist clockwise until it clicks. The step often missed is removing both the rear lens cap and the camera body cap before attempting to mount.

What maintenance will the 7 rounded diaphragm blades need over time?

The 7 rounded diaphragm blades are internal and require no user maintenance. Keep the front and rear glass clean with a blower and microfibre cloth; avoid touching the blade mechanism. If aperture actuation becomes stiff, professional service is needed.
