Review: Voigtländer Heliar 40mm f/2.8 II on the Nikon Zf

Voigtländer lenses have always carried a reputation for character, craftsmanship, and compact form. The Heliar 40mm f/2.8 II is no different—a small, all-metal lens that feels like a vintage gem but fits neatly into today’s mirrorless workflows. I had the chance to pair it with the Nikon Zf using the K&F L/M – Nik Z adapter, and the experience was equal parts refreshing and contemplative.

A Compact Classic with Modern Charm

Sweet Characteristics

Despite its modest f/2.8 maximum aperture, the Heliar delivers in spades. Its sharpnessis excellent across the frame, especially once stopped down just a little. Landscapes, street scenes, and general walkabout photography all shine.

Of course, you will feel the limitation of the f/2.8 which won’t give the same subject isolation as a faster lens, and bokeh can feel restrained for portraitures. Still, subject rendering remains pleasing. And true to Voigtländer’s tradition, images come out with strong micro-contrast and that subtle pop that sets them apart from sterile modern optics.

Build & Handling

The Heliar 40mm f/2.8 II is a lens that invites you to slow down. Its all-manual operation might feel like a drawback to some, but on the Nikon Zf - already a camera designed with a nostalgic nod - it feels natural. Focusing is smooth, the aperture clicks reassuring, and the compact size balances perfectly on the body. Also be aware the aperture ring has a tendency to slip in rotation with the focusing, and with the non-native adapter, infinity focus is a fraction from the position without one.

In Use with the Nikon ZF

Pairing this lens with the Nikon Zf is more than just functional - it’s aesthetically satisfying. The retro styling of both body and lens complement each other, and shooting in manual focus aligns with the Zf’s tactile controls.

For street shooting and documentary work, the 40mm focal length hits a sweet spot - slightly wider than the “nifty fifty,” but tighter than a 35mm. It feels versatile without being generic.

Who’s It For?

I would warrant a guess that street photographers who value compact size and sharp rendering, travel shooters looking for a small, reliable lens to carry everywhere would love this Heliar. As well as all the classic lens enthusiasts who enjoy manual focus as part of the creative process.

Final Thoughts

The Voigtländer Heliar 40mm f/2.8 II may not be the fastest or flashiest lens on the market, but it doesn’t try to be. What it offers instead is precision, charm, and a pace that makes you more intentional behind the camera. On the Nikon Zf, it feels like a perfect pairing of old and new—one that reminds you why you fell in love with photography in the first place.
