Sigma 56mm F1.4 Review

I have been a long-time preacher of the Sigma trio (that is the wide angle 16mm, the midrange 30mm, and this telephoto) yet it took me years before I finally tried the tightest in the trio: this lens.

My favorite lens of all time is Sigma’s 30mm, so their telephoto offering had some big expectations to fill. In this article, I’ll be sharing dozens of sample photos that I’ve taken with the Sigma 56mm F1.4 along with my impressions as a long-time Sigma fanboy (spoiler alert: this lens kick ass).

Size & Weight

Alright ya’ll, one of my favorite parts of shooting on APS-C is that the lenses are usually pretty darn small. When I first took this one out of the box, I expected something similar in size to my beloved 30mm F1.4, but nope… it’s actually even smaller!

How Sigma managed to cram an F1.4 aperture with some of the best glass on the market into such a small barrel is beyond me, but I’m here for it. Lenses like this are why I switched away from a bulky DSLR system many many years ago.

Build Quality

Build quality, while not on par with a GM lens for example, is solid. It’s a mix of metal and polycarbonate (a sort of plastic compound type mix) that feels pretty sturdy but is a bit of a fingerprint magnet.

I can’t speak for the longevity of the 56mm itself, but I’ve owned Sigma’s 30mm for six years now (as of time of writing) and have had no durability issues. I strongly suspect this lens should last just as long as it’s essentially made out of the same stuff.

Aesthetically, I think the physical appearance of this lens is its only weak point. It’s not ugly but it’s just a boring plain black barrel without much adornment. But hey, a lens’s aesthetics are literally at the bottom of the list when I rate a piece of gear anyway. I do, however, absolutely love how the front element is just a giant piece of glass. It’s like staring into an endless dark abyss…

Usability/Ergonomcis

Ahem, anyway… from a usability standpoint I found the lens quite comfortable to use. Given that it’s so small and relatively light, I didn’t feel fatigued or weighed down by it when wandering around the city. The boring but functional included lens hood provides a really nice gripping point.

I primarily used it on my ZV-E10 but also a few times on my old a6000. Given that these cameras have roughly the same dimensions, the lens felt equally great on both. Perfectly well balanced, and not too front heavy yet also not too flimsy or light.

No physical buttons at all, not even an AF/MF switch. Like I said earlier, very minimalist. The 56mm F1.4 does in fact have a bit of weather sealing, however. There is a gasket around the lens mount that’ll help with light splashes, but I probably wouldn’t test my luck, especially with a non-sealed body.

One major negative of this lens is that it lacks any sort of in-lens stabilization. Nowadays, most Sony bodies are stabilized, but unfortunately the two that I own are not so missing out on OSS is always a bummer. That being said, I can see why Sigma omitted it for a few reasons: the lens would get larger/heavier, cost would go up, and frankly the F1.4 aperture off-sets a lot of need for stabilization anyways.

Autofocus

There’s not a ton to talk about when it comes to autofocus. It performs pretty well and is highly reliable. If you’ve used a newer OEM lens (such as the Sony 11mm F1.8 for example), this might be a bit “slower” but I personally didn’t have any problems.

The proof is in the pudding here… or rather, the proof is in the photos. Check out the shots below to see how well this lens was able to track these fighter jets going 700mph.

Image Quality

Alright, let’s talk about the part everyone cares about most: image quality. As I mentioned in the intro, the Sigma 56mm F1.4 is considered the statistically sharpest lens for Sony APS-C cameras. Now, I’m going to be honest, my reviews don’t get for scientific. I go out, I actually use the lens in the field as opposed to photographing a sharpness chart, then I share my photos.

In case it isn’t already obvious… the photos look good. At F1.4, we see flawless center sharpness but a bit of fall-off near the corners (note you also have a razor thin focus plane). My go-to was usually F2.5 or F2.8 or portraiture. The lens produced incredible edge-to-edge sharpness here and I found it expanded the focus plane enough to get every feature of a person sharp.

I also shot at F8 a lot. While this lens was clearly designed for standard telephoto work in mind (portraits, etc.), I ended up using it for a lot of landscape stitches. Edge-to-edge sharpness unsurprisingly sure is handy when stitching panoramas.

One issue I want to call out is distortion. Most telephoto lenses don’t suffer from distortion, but there is a bit here. Thankfully, I found it was easily fixed in post processing. For flare and chromatic aberrations, I literally couldn’t find a flaw.

Bokeh, thanks of course the tight focal length and F1.4 aperture, absolutely top notch. It’s hard to “describe” bokeh in words, so I’ll just drop a sample gallery below. Enjoy.

Should you buy?

So yeah, in case I haven’t made it abundantly clear, this lens is nuts. In most of my reviews, I’m able to say, “the lens has this or that issue,” or something along those lines, but not here. This lens just hits everything right and I don’t think it’s a bad pick for anyone.

PS: prefer a wider focal length? Me too. If 56mm is a bit too tight for you, check out my six year review of Sigma's 30mm. It's essentially the same thing, just wider.
