Sony 14mm f/1.8 GM In The Field

DISCLAIMER: I am a Sony ambassador and I received the lens weeks before it was announced. This article is not called a ‘review’ but is simply a summary of my impressions when using this lens in the field.


After the release of the 12-24 f/2.8 G-Master lens I thought that that was it: Sony finally released my dream lens. But on a call with Sony a few weeks ago I was told that ‘something was coming, and it had my name on it’. And that could only mean 1 thing: The one and only lens that was still missing for me in the Sony lens line up was a fast wide angle prime. And I was correct: The Sony 14mm f/1.8 GM is here!


It’s light!


And I know what you’re thinking. I was thinking it as well: This thing must be big and heavy. But we have been surprised by Sony in the past. Sony seems to utilise their mirrorless cameras and lenses the best when it comes to portability and weight. Their G-Master primes have (almost) always been lighter than the competition and it seems that the engineers challenge themselves by keep pushing the bar. I remember I was shocked by the size and weight of the 24mm f/1.4. But the 14mm f/1.8 is on another level: It’s 460 grams only. And that's a lot lighter than the Sigma 14mm f/1.8 (DSLR) lens. I don’t know how they did it, but they did. I wonder if the Sony engineers ever take a holiday?


Its not just on the spec sheet, it really does weigh 460 (+1) grams.


Now Sony doesn’t make things easier with this lens. There are just so many great Sony native wide angle lenses on the market right now, and I love my 12-24GM. But what If I would bring the 14mm f/1.8 and the 24mm f/1.4 instead of the 12-24GM? All 3 lenses are great. And if you look at the total weight of the 14mm (460g) and 24mm (445g) which is just over 900gr, the difference is only 50 grams over the 850gr 12-24 f/2.8 GM. But it’s very nice and versatile to use the 12-24 instead of having to switch between lenses. This will be a tough choice for people I’m sure. But the bottom line is: With the 14mm f/1.8 Sony ‘completes’ an incredible native line up of wide angle lenses.

The Design

Now when we look at the lens we can see it is compact for its properties. It fits well in line up of Sony’s primes. When we see it next to the 24mm f/1.4 we can see it’s only slightly bigger. Mounted on the Sony A7RIV body it doesn’t look big at all, and it’s simply a nice kit to walk around with.



Other than the size and weight, there are not much surprises when we look at this lens. It has a dedicated AF/MF switch, one extra button, and a switch to set the aperture to click-less. It looks like Sony implements this on all of their newer GM lenses which also makes them great for video.

The aperture can be set manually with the aperture ring and goes from f/1.8 to f/16 and then there’s the ‘A’ to let you control the aperture via the camera body.


The lens has a nondetachable hood to protect the front element from bumping into things. It has no filter thread, but surprisingly just like the 12-24 f/2.8 GM, there’s a possibility to use filters on the back of the lens.


Sharpness, Distortion & Bokeh


Let’s take a look at how this lens performs in the field. Someone interested in a wide angle prime like this is most probably going to use it for Landscapes, Cityscapes, Architecture, and of course: Astrophotography. Now over the last few weeks I decided to leave my 12-24GM at home and simply carry this lens with me to photograph.



To start off I photographed some Architecture. This was mainly to check the distortion and sharpness of the lens.


I tried to shoot some interesting angles of modern buildings in the city of Amsterdam. When we look at the photos (especially the last one) we can see there is not much noticeable distortion going on. Upon writing this article, no lens profiles were available for this lens so I didn’t do any corrections. But even without any lens profile applied, lines look straight.

Let’s take a look at the sharpness on this image:

Taken at f/8 from a perfectly still tripod, take a look at a crop of the left side:

Even at the complete edge, everything is still super sharp and we can see all the little details from the bricks.

Now here is a corner crop from the bottom right:

Even the sharpness at the absolute corner is impressive.

This lens has Two XA (extreme aspherical) elements along with two ED (Extra Low dispersion), one Super ED and one aspherical element.


So yes, with a quick test the sharpness looks great, as one might expect from a Sony G-Master prime lens. But there’s something that really impressed me: The center sharpness at f/1.8. Let me show you an example, and with that I will immediately address the bokeh of this lens. And I hear you thinking: who would use the bokeh of this lens anyway? And you might think different when you see this:

This was shot wide open at f/1.8. I was really impressed with the nice soft bokeh around the subject. But before we look at some other bokeh images, let’s take a look at the sharpness at f/1.8.

When I saw this center crop I was extremely impressed. We’re looking at more than 100% here (probably 200 or so) and you can see every little detail on the letters and the little carvings on the lens. What impressed me the most is that there are basically no aberrations and ‘glow’. You know when you use fast lenses wide open? You will often see a tiny bit of glow around the bright and contrasty parts. With this lens, it’s absolutely zero.

And when we are checking the Bokeh anyway, let’s take a look at some more shots with a creamy background. Because it’s actually quite fun to shoot extreme perspectives with creamy backgrounds with an extreme wide angle lens:
