A half silvered mirror, also known as a semi-transparent mirror, is a type of mirror that reflects about half of the light that hits its surface and transmits the other half. This creates a partially reflective and partially transparent surface.

Now we’ve given the Samyang 12mm a thorough introduction, let’s delve into the ways in which this lens arguably cements itself among the best third-party lenses on the market today, before discussing the ways in which it could be improved.

The Samyang 12mm F2, also marketed as the Rokinon 12mm F2 throughout North America, is an ultrawide-angle prime lens that has justifiably been on the receiving end of much praise since it was released.

While wide-angle lenses can be used for specific kinds of portraits, they are far from the most popular choice. Even photographers who deliberately shoot portraits with ultrawide-angle lenses to achieve a certain effect rarely choose to go as wide as 12mm.

Half silvered mirrors are typically made by coating a glass or plastic substrate with a thin layer of metal, such as silver or aluminum, on one side. This creates a reflective surface while still allowing light to pass through the other side.

Half silvered mirrors work by reflecting part of the incoming light and transmitting the rest. This is achieved through the thin metal coating, which allows for some light to pass through while still reflecting a portion of it.

While the Samyang 12mm F2 is not a badly built lens by any stretch of the imagination, my copy at least doesn’t quite live up to the exceedingly high standards set by Fujifilm and other manufacturers with the lenses they produce for their cameras.

Its 6 rounded aperture blades also ensure that at its wider apertures, the Samyang 12mm F2 produces very soft and smooth bokeh to add additional depth to your images.

This wouldn’t be a very good review of this lens if it didn’t touch on its potential shortcomings alongside its strengths, so let’s discuss the ways in which this lens may not be right for some.

Finally, the Fuji X-Mount version of the Samyang 12mm F2 that I’ve been using weighs in at just 260 grams (or 9.17 ounces). The 12mm F2 is an incredibly lightweight lens, especially when compared to one of the other lenses I always travel with, the Fujinon XF 55-200mm, which weighs in at well over double that weight.

So, there we are: a quick overview of the Samyang 12mm F2 and why we think it’s one of the best-value third-party lenses on the market today.

I picked up my version of this lens in mint condition online for just £130, or approximately 160 USD at the time of writing. For a lens of this quality, this is an absolutely incredible deal. At the time of writing, you can pick one up on MPB for even less – the cheapest I found was being sold for just £99, or 124 USD.

On my copy of the Samyang 12mm F2, for example, the focus ring isn’t quite lined up correctly meaning that it shows my minimum focus distance to be a tiny bit shorter than 0.2m, while my maximum focus distance is just shy of the infinity symbol. While it doesn’t exactly ruin my experience shooting with this lens, it is immediately noticeable and something that you simply would not get with another camera manufacturer’s own lenses.

The Samyang 12mm F2 is constructed of a total of 12 elements in 10 groups, of which two are aspherical lenses. Its aperture, controlled by 6 rounded aperture blades, ranges from a bright f/2 all the way to f/22, although in my experience the sharpest results are generally had at f/4 or f/5.6. That being said, even at other apertures, I’ve found that the 12mm F2 produces sharper results than almost any other third-party lens I have tested.

Of course, how compact and light a lens is doesn’t matter one bit if the results it produces aren’t up to standard. Luckily, this is another area in which the Samyang 12mm F2 punches well above its proverbial weight.

The first downside, and probably the most likely to be considered a dealbreaker by some photographers, is the Samyang 12mm F2’s lack of autofocus. It certainly takes some getting used to, especially since the majority of lenses available today have autofocus capabilities, even if these aren’t the fastest or most accurate. Fujifilm, for example, don’t sell a single XF-line lens without autofocus.

Granted, there aren’t all that many directly comparable lenses on the market. Whether you’re on the hunt for a comparable Fujifilm X-Mount, Canon M-Mount or Sony E-Mount lens, you will have to compromise either in terms of focal length, maximum aperture or, most likely of all, both. If you’re on the market for a great value lens that’s fantastic for astrophotography, it’s difficult to go wrong with the Samyang 12mm F2.

A 12mm focal length just about falls into the ultrawide-angle category of lenses. With the Samyang 12mm F2 being a prime lens, it is limited to this focal length only, which will make it unsuitable for some depending on the style of photography they practice.

Of the 103 lenses the South Korean manufacturer has pumped out in the past few years, the 12mm F2 is among their most popular. While you would expect its fixed, ultrawide focal length and its lack of autofocus to limit its appeal to a smaller niche, I would argue that the Samyang 12mm F2 could be a valuable asset to any photographer’s kit.

As mentioned in this article, the Samyang 12mm F2 has a very bright maximum aperture of, you guessed it, f/2. This allows for the use of faster shutter speeds in low light situations, making sharp handheld shooting a much more achievable prospect even if, like me, you don’t have the steadiest hands. And with it being an ultrawide prime lens, the Samyang 12mm’s wide maximum aperture of f/2 is what makes it such a great option for astrophotography.

Half silvered mirrors have a variety of uses, including in optical experiments, laser technology, and photography. They are also commonly used in one-way mirrors, where one side appears as a mirror while the other side allows for viewing through the glass.

There are versions of the Samyang 12mm that are compatible with Fujifilm X-Mount, Canon M-Mount, Sony E-Mount and Samsung NX-Mount. For this review, I have been using and testing the Fuji X-Mount version of this lens mounted on my Fujifilm X-T2.

Thanks to its wide maximum aperture, astrophotography is a genre in which the Samyang 12mm F2 has become particularly popular. It’s so capable in this field in particular that I keep this lens despite already owning the Fujinon XF 10-24mm. While the XF10-24mm has the 12mm focal length covered, it falls well short of the Samyang 12mm F2 due to its maximum aperture of f/4.

I use the Fuji X-Mount compatible version of this lens, which weighs in at a negligible 260g (9.17 ounces) and measures just 59mm (2.3 inches) in length. In comparison to the other lenses that I travel with, the XF10-24mm and the XF55-200mm, the Samyang 12mm is barely even noticeable in my camera bag.

An immediately obvious benefit of the Samyang 12mm F2 is its size and weight. These statistics present welcome news for travel photographers, or any photographer that likes to take their kit out and about with them.

That being said, when it comes to the types of photography the Samyang 12mm excels in, autofocus is rarely needed. When it comes to shooting landscapes and astrophotography, you’ll likely just need to set your focus to infinity. If you were shooting portraits, however, it wouldn’t be quite as easy as that. In the end, whether the lack of autofocus is a dealbreaker for you all comes down to what you intend to do with this lens.

Being a manual focus lens, the Samyang 12mm F2 can take some getting used to for those who primarily shoot using autofocus. When mastered, however, it can focus on objects just 20cm (or 7.87 inches) away which, when paired with the smooth bokeh achieved at its widest aperture of f/2, makes the 12mm a very capable camera for some moderately close-up photography.

Yes, the amount of light reflected by a half silvered mirror can be adjusted by changing the thickness of the metal coating. Thicker coatings will reflect more light, while thinner coatings will transmit more light. This allows for flexibility in the use of half silvered mirrors for different applications.

Finally, something that we simply have to mention when covering this lens, is its price. While this is hardly a feature of the lens itself, it’s an additional bonus for every budget-conscious photographer.
