Sigma just announced three autofocus lenses for Fujifilm X-mount: 16mm f/1.4, 30mm f/1.4, and 56mm f/1.4. This is a big deal because 1) Sigma lenses are pretty darn good yet typically “affordable” and 2) it’s good to have options, which has been a little missing for Fujifilm photographers. These lenses can be pre-ordered and will ship in April.
I’m sitting here sipping my first cup of coffee, and already there has been plenty of press and early reviews published on these three lenses. What can I add that hasn’t already been said?
I’m glad that Sigma announced these lenses. I think it’s good. But I’m going to give you three quick reasons why you should not buy them. I’ll briefly explain why the similar Fujinon offerings are superior, and you should go with those instead.
First, there are no aperture rings on these Sigma lenses. Sigma literally took three already existing lenses for other mounts and made them compatible with X-mount. These lenses aren’t designed for the Fujifilm experience—they’re designed for Sony, in which you use a command wheel to adjust the aperture (yuck!). It is true that some Fujinon lenses work this same way, but most don’t. Most have an aperture ring, and that’s an important aspect of shooting Fujifilm. Sigma should have redesigned their lenses to include an aperture ring, but they didn’t, and I predict their X-mount lenses won’t sell as well because of this.
Second, behind the scenes, your Fujifilm camera is secretly fixing little flaws in the Fujinon glass. Fujifilm programmed their cameras to do this automatically, so you don’t know that there’s actually a little vignetting or chromatic aberrations or whatever else that doesn’t show in the pictures but is actually there if the camera wasn’t making this adjustment. Your camera won’t do this for third-party lenses. For the greatest optimization, stick with native glass.
Third, these three Sigma lenses are rather plain-looking. They don’t really match the retro-vibes of most Fujifilm X cameras because they look like modern lenses. Not all Fujinon lenses were modeled after vintage designs, but many of them were, and they match the stylings of the body much better than these Sigma offerings.
With all that said, there’s definitely a market for third-party autofocus lenses; however, they must offer something that Fujifilm doesn’t. It could be a focal-length and/or aperture. It could be quality. It could be speed. It could be size and/or weight. It could be price. What do these Sigma lenses offer that Fujifilm doesn’t? Let’s take a look.
Fujifilm offers a 16mm f/1.4 lens already—a high-quality, quick lens that’s smaller than the Sigma offering. The Sigma is less than half the price.
Fujifilm offers a 33mm f/1.4—a high-quality, quick lens that’s a similar size (and focal-length) to the Sigma offering. The Sigma is less than half the price.
Fujifilm offers a 56mm f/1.2—a high-quality, quick lens that’s a similar size to the Sigma offering (but larger maximum aperture). The Sigma is less than half the price.
Now you see why one would choose a Sigma lens over the Fujinon: to save some cash. They’re priced significantly cheaper while offering something similar. If you can afford it, the Fujinon lenses are better, but if not, this is a solid alternative that’s friendlier on the wallet. There are also lesser-expensive Fujinon options worth considering, which maybe don’t have the tech-sheet wow factor, but are otherwise fantastic lenses that you’re sure to be happy with.
