Sigma 30mm f/1.4 DC DN C (Contemporary) Autofocus Lens for MFT (Micro Four Thirds), Black {52}

$262.00
Sigma 30mm f/1.4 DC DN: a proven fast prime for MFT shooters.
The 30mm f/1.4 DC DN sits in a field-of-view sweet spot that reviewers describe as sitting between a 35mm and a 50mm full-frame perspective, functional enough for everyday work, tight enough to isolate subjects. The f/1.4 maximum aperture is the main event, giving you real low-light capability and shallow depth of field from a lens weighing just 265g. At 73mm long and 65mm in diameter, it pairs better with SLR-shaped MFT bodies than with the slimmest pancake-style cameras.
The optical formula runs 9 elements in 7 groups, including one aspherical and one double-sided aspherical element, the kind of construction that keeps aberrations in check at wide apertures. Autofocus is handled by a stepper motor with internal focus, which keeps the barrel length fixed during focusing and makes it a workable option for video shooters who rely on a camera's continuous AF than a dedicated focus puller. The 9-blade rounded diaphragm produces smooth out-of-focus rendering when you stop down. A 52mm filter thread keeps filter costs reasonable.
As an autofocus f/1.4 prime in the MFT ecosystem, this lens occupies a distinct price tier, and for photographers who want that extra stop over the common f/1.8 offerings, the Sigma is an answer.
Who It's For
Street photographers who work in low light will find the f/1.4 aperture genuinely useful when ambient light drops and raising ISO isn't the preferred solution. Portrait shooters drawn to a slightly telephoto-leaning field of view get a 9-blade rounded diaphragm that softens backgrounds at wider apertures. Documentary and travel photographers will appreciate the 265g weight and internal focus, which keeps the package compact and the front element stationary. Videographers shooting run-and-gun work benefit from the stepper motor's quiet, continuous autofocus performance without the need for manual pulling.

FAQ
- What's the field of view on MFT bodies?
- The dpreview review describes it as sitting between a 35mm and 50mm full-frame perspective-functional for everyday work but tight enough to isolate subjects. It's an easily usable balance between wider and tighter framing.
- Does this lens have autofocus?
- Yes, it uses a stepper motor with internal focus, so the barrel length stays fixed during focusing. That makes it workable for video shooters relying on continuous AF rather than manual focus pullers.
- How close can you focus?
- Minimum focus distance is 0.30m (11.81"), with a maximum magnification of 0.14×.
- Will it balance well on my MFT camera?
- It depends on the body. At 73mm long and 65mm in diameter, it pairs better with SLR-shaped bodies like the GH4 than with slimmer PEN-series or E-M5 II cameras, where it can feel bulky and unbalanced.
- What filter size does it use?
- 52mm. Standard and affordable to outfit.
- How does the bokeh look?
- The 9-blade rounded diaphragm produces smooth out-of-focus rendering when you stop down from wide-open.
- Is this lens sealed against dust and moisture?
- No, it has no weather sealing.
