Question 1

What cameras is the Sigma 45mm f/2.8 DG DN Contemporary compatible with?

Accepted Answer

The Sigma 45mm f/2.8 DG DN Contemporary uses the L-Mount standard, which means it fits any camera with an L-Mount bayonet — including Panasonic Lumix S-series bodies like the S5II and S9, Leica SL-series cameras, and Sigma's own fp and fp L. It won't fit Sony E-Mount or Nikon Z cameras without an adapter.

Question 2

How does the Sigma 45mm f2 8 compare to a 50mm lens?

Accepted Answer

The 45mm focal length gives you a very slightly wider field of view than a 50mm, which many photographers find more natural for street and reportage shooting — you need to stand just a touch closer to fill the frame the same way. The practical difference is subtle, but the 45mm often feels less 'compressed' for environmental portraits where you want to show some context around your subject.

Question 3

Is the autofocus on the Sigma 45mm f/2.8 DG DN fast enough for street photography?

Accepted Answer

The stepping motor AF system is designed for quiet, smooth focusing — ideal for video and discreet street use. Multiple real-world reviews describe it as quick and accurate for walk-around shooting. It's not a sports-spec AF motor, but for still subjects and everyday candids it keeps up without hunting.

Question 4

Can I use this lens for video on L-Mount cameras?

Accepted Answer

Yes — the stepping motor is specifically well-suited to video because it operates quietly and moves focus smoothly without the jerky steps you can get from older AF motor types. The 45mm field of view also works well for cinematic 'normal' shots and vlogging-style footage.

Question 5

How close can the Sigma 45mm f/2.8 DG DN focus?

Accepted Answer

The minimum focus distance is 0.24m (24cm), which lets you get surprisingly close to small subjects. It won't replace a dedicated macro lens, but you can fill a good portion of the frame with a flower, a product, or a food dish, adding useful versatility for an everyday prime.

Question 6

Is buying a used Sigma 45mm f/2.8 DG DN Contemporary worth it?

Accepted Answer

This lens is compact and built to handle daily use, so a second-hand copy in good condition is a practical buy. At Camera-tweedehands.nl every pre-owned lens is individually inspected and photographed so you know exactly what you're getting, and each item carries a minimum 12 months warranty. For a lens you'll keep on the camera most of the time, a used copy makes strong financial sense.

Question 7

What filter size does the Sigma 45mm f2 8 DG DN use?

Accepted Answer

The filter thread is 55mm — a common and affordable size, so polarisers, ND filters, and UV protectors are easy to find without paying a premium for larger glass.

Question 8

How does the Sigma 45mm f/2.8 compare to the TTArtisan 40mm f/2?

Accepted Answer

The TTArtisan 40mm f/2 offers a one-stop wider maximum aperture, but it's a manual-focus-only lens. The Sigma 45mm f/2.8 DG DN has fully electronic autofocus via its stepping motor, making it far more practical for quick street shooting or anyone who relies on AF. If autofocus matters to you — especially for video or fast-moving situations — the Sigma is the more versatile choice.
