Helios 44-2 review - beyond swirly bokeh

Get a quality modern lens, and you’ll produce technically perfect images. The committee of camera reviewers on YouTube would zoom 200% and put their seal of approval.

Get a quirky Helios 44-2; you’ll suffer with focus, contrast, direct sunlight, and the mood of Soviet mechanics. It can be used on modern cameras, and it does a few things that modern lenses don’t. Let’s talk about it.

Note that all images in this post are color corrected and have minor edits, but they preserve the lens's original aesthetic. (photo made at Espoo Archipelago, Finland)

Disclaimer. This is not a lab review. I will not photograph a brick wall and discuss corner sharpness. This is a field review. I specialize in dark atmosphere, nature, and people. I’ll talk about what this lens does to them and to the way you shoot.

Why Helios?

Short version: you get swirly bokeh, low contrast, and weird artifacts when pointing at direct light. All for the price of around 40-80 EUR.

If you use Helios 44-2, you are likely chasing its lo-fi stylistic imperfections. Images would look less modern, less sharp, less sterile. Some of these effects can be added in post, but swirly bokeh is not easy to fake convincingly.

So, if you like the aesthetic of the images made with Helios and you want to get them straight out of the camera, this lens is a strong addition! This is not a replacement for modern lenses; it is a character tool.

What is Helios 44-2?

Helios 44-2 is a Soviet-era 58mm f/2 manual-focus lens, normally found in the M42 mount. It was produced in large numbers, mostly as a standard lens for Soviet Zenit cameras from the 60s until the 90s. This is why copies are still easy to find.

It is one of the most common entry points into vintage lenses. It is small, inexpensive, and compatible with most interchangeable lens DSLRs and mirrorless cameras.  But the main reason people love it is that swirly bokeh.

Swirly Bokeh?

The internet nearly made a religion out of this optical effect. At f/2-f/2.8, especially on full-frame, the out-of-focus background area starts to rotate around its center. I have to admit, the effect looks a bit surreal. But I think that, just like anything repeated too many times, it loses its value.

You can see the out-of-focus area has a tilt. But does it make the image better? (photo made at Espoo Archipelago, Finland)

I think the swirly bokeh effect makes a lot of sense when it adds something to the composition, instead of stealing attention. If someone looks at the photo, what is the first thing they would notice? Quite often, the viewer's eye starts to wander between the subject matter and “why the sky looks so weird“. I certainly hope people are trying to say something with their images, and it is not “I own old glass” or “look at my bokeh“.  

I think the most straightforward use is to place your subject right in the center and let the background wrap around it. Even if the swirl is subtle, it can give more weight ot the subject. I personally think it is even better when it is subtle. The viewer sees emphasis on the subject, but cannot understand that it is coming from bokeh.

For comparison. The image on the left shows Helios 44-2 at f/2, and the image on the right shows Canon EF 50mm f/1.8 at f/1.8. Pay attention to the accent of the central subject and contrast.

I also think the swirl can add a bit of unsettlement. The background doesn’t feel still; it suggests motion instead. This can increase the effect of, let’s say, windy weather. If you try picturing something in a strong wind, it becomes more storm-like.

What if you photograph a snowstorm, which already rotates?

What if you photograph your subject in front of a Ferris wheel, and you want the wheel to look like it’s in motion?

This one has some wind, but the tilt makes it more pronounced

Low-contrast portraits

Portraits are where it gets interesting; compared to modern lenses, Helios 44-2 feels much softer. Modern sharp lenses turn portrait into evidence - pores, small imperfections feel aggressively present. Sometimes, all possible details are exactly what you look for as you fine-tune everything in post.

But also, the opposite can be true. Helios means less inspection - more mood. If you like the aesthetic, the question is simple: would you trade immediate lo-fi character for less detail and less technical precision? The answer depends on your goals.

About low light and lens flare

At f/2, you get a respectable low-light performance. Everything about low contrast and swirly bokeh remains unchanged. But there are a few additional things to consider.

First is focus. Whether it is a DSLR or a modern mirrorless camera, I find it challenging to track the subject in the dark. After losing focus on the images I’d love to have in my library, I decided to shoot only stationary objects. Scenes that are about mood, not timing.

Low light is also a good context for discussing lens flare. On Helios 44-2, it is enormous. You need to pay extra attention to city lights. Helios 44-2 doesn’t have modern coatings, so lens flare shows up in all kinds of places. This could be avoided or embraced; light may actually bend into some interesting shapes.

Handling and durability

The Hlios 44-2 is compact and light, around 200 g. depending on the version. It isn’t a problem to carry it, just to have more optionality. However, no modern weather sealing, no modern dust protection, and no electronics to damage. I would avoid sand, rain, and careless packing.

I once put mine too carelessly at the bottom of the camera bag during a rough bus ride on a wild country road. The vibration caused the lens to come apart, and the glass fell out of the lens body. I managed to repair it quite cheaply. Spare parts are common. But since then, I have carefully thought about when to bring it and when not.

Adapting Helios 44-2 to modern cameras

On most modern mirrorless cameras, adapting Helios is simple: buy an M42 adapter for your mount, attach the lens, and accept that nothing electronic will happen. No autofocus, no aperture control from the camera, no EXIF data. You focus manually and set the lens aperture.

For current mirrorless systems, look for an M42 adapter for Sony E, Canon RF, Nikon Z, Fuji X, Micro Four Thirds, or L-mount. These adapters are usually simple mechanical tubes. For legacy DSLR mounts, Canon EF lenses work well, but Nikon F lenses require lens correction to enable infinity focus. Modified lenses are sold online for a slightly higher price.

Sensor size also affects how the lens behaves. On full frame, you get the classic Helios look. The field of view stays close to the original 58mm, and you use the entire lens image circle. That is important because the famous swirly bokeh mostly lives toward the edges. If you want the strongest Helios character, full frame is the easiest way to see it.

On APS-C, the Helios 44-2 is still a 58mm lens, but the cropped field of view makes it behave like a short telephoto. On most APS-C cameras, it gives roughly the same framing as an 87mm lens on full-frame; on Canon APS-C, closer to a 93mm full-frame equivalent. That can work very well for portraits, but the crop uses less of the outer edge of the image circle, so the swirl becomes weaker. You still get low contrast, softness, and vintage rendering, but less of the dramatic background rotation people usually associate with Helios.

On Micro Four Thirds, it becomes roughly an 116mm-equivalent lens. That is already quite tight. The classic swirl is much harder to get because the sensor mostly uses the central part of the image. You may still like the lens for portraits, details, and soft vintage rendering, but do not buy it expecting full swirly bokeh.
