Sigma EX DC 10mm f/2.8 HSM Fisheye 10mm

The Sigma 10mm f/2.8 EX DC HSM is a well built, super light fisheye for Sigma APS-C bodies. It captures a 154 degree field of view with a bright f/2.8 aperture and impressive close focusing. At $745 to $810 USD, it's a specialty tool for creative shooters who want that distorted look. Not a general purpose lens, but great at what it does.

The headline number here is the 154 degree diagonal field of view. That's a lot of world in one frame, and it's what gives the lens its signature look. Straight lines become curves, corners stretch out, and anything near the edge of the frame gets pulled into the distortion. The f/2.8 max aperture sits in the 85th percentile for fisheye lenses, which means you can shoot in lower light or get a shallower depth of field than you'd expect from something this wide. Not that shallow depth of field is really the point with a fisheye, but it's there when you want it.

Close focusing is a real strength here. The 1:3.3 magnification ratio puts it in the 91st percentile for macro capability among fisheyes, which is unusual. You can get close enough to make small subjects look huge while still keeping that distorted wide perspective. The bokeh quality is also surprisingly decent, landing in the 83rd percentile. It's not going to replace a dedicated portrait lens, but the out of focus areas don't look harsh or busy. Autofocus is middle of the pack at the 54th percentile, which is fine for a lens like this. You're probably not tracking fast action with a fisheye anyway.

The competitors in our database are mostly not fisheyes, which tells you something about how niche this lens is. The Viltrox AF 13mm F1.4 XF is a wide angle but not a fisheye, so it gives you a more natural perspective with less distortion. It's also faster at f/1.4, which matters if you shoot in low light. But it won't give you that 154 degree bendy look. The Tamron 28-300mm is a superzoom, which is the opposite of this lens in every way. It's versatile, this is not.

The Nikon Z 17-28mm f/2.8 and Sony E 18-135mm are both more practical lenses for everyday shooting. They cover wider ranges, they're sharper in the corners, and they don't force you into a specific creative style. But none of them can do what this Sigma does. If you want the fisheye look, you need a fisheye lens. There's no zoom range or post processing trick that really replicates it. The Panasonic Leica 12-35mm is a great all around lens, but again, it's a normal zoom. This Sigma is a specialty tool, and comparing it to general purpose lenses is like comparing a skateboard to a minivan.

Pricing is a bit of a puzzle here. The lens runs between $745 and $810 USD across four listings, which is not cheap for what is essentially a specialty lens. You're paying for the unique perspective and the solid build, not for versatility. The bundle does soften the blow a little with the memory card, pouch, and cleaning kit included, but those are all things you probably already own if you've been shooting for a while.

Compared to other fisheye options, this sits in a weird middle ground. It's more expensive than some manual focus fisheyes from third party brands, but cheaper than first party options from Canon or Nikon. The value really depends on how much you'll use that distorted look. If it's a once in a while creative tool, the price might sting. If you shoot skateboarding, BMX, or anything where fisheye is part of your visual identity, it's a reasonable investment.

The Sigma 10mm f/2.8 EX DC HSM is a weird little lens, and I mean that as a compliment. It's a fisheye built specifically for APS-C DSLRs, which means it's not trying to be a general purpose wide angle. It's trying to bend reality into a 154 degree circle of chaos, and honestly, it does that job well. This is the lens you buy when you're bored of normal photos and want to make your skateboard footage look like it was shot inside a snow globe.

Who's this for? Creative shooters, mostly. People who want that exaggerated, distorted look for action sports, music videos, or just messing around with weird perspectives. The f/2.8 aperture is constant, which is nice for a fisheye, and the close focusing distance of 5.3 inches means you can get right up in your subject's face. Literally. The front element can get within 0.7 inches of whatever you're shooting.

Sigma designed this for their own mount, so if you're on a Sigma APS-C body, this is a native fit. The build quality is genuinely excellent, sitting in the 96th percentile in our database. It feels solid without being heavy, and at 104 grams, you'll barely notice it in your bag. The bundle also throws in a memory card, pouch, hood, and cleaning kit, which is a nice touch if you're starting from scratch.

Skip this if you want a general purpose wide angle. The fisheye distortion is baked into every single photo, and while it's fun for a while, it gets old fast if you're trying to shoot landscapes or architecture. The landscape score in our database is 37.9 out of 100, which is the weakest area for this lens. Straight lines don't exist here, and that's a problem for most landscape work.

Also skip it if you're not on a Sigma APS-C body. This lens only fits Sigma's mount, so Canon, Nikon, Sony, and Fuji shooters are out of luck. If you want a fisheye for another system, look at third party manual focus options or your camera brand's own fisheye offerings. And if you're new to photography and this would be your only lens, don't do it. Get a standard zoom first, learn the basics, then add a fisheye as a creative tool later.

If you're on a Sigma APS-C body and you want that classic fisheye look for action sports, creative portraits, or just having fun with weird perspectives, this lens delivers. The build quality is genuinely impressive, the f/2.8 aperture is useful, and the close focusing ability opens up creative options you don't get with most fisheyes. The 154 degree field of view is the whole point, and it does that extremely well.

But if you're looking for a general purpose wide angle, this is not it. The optical quality is average, there's no stabilization, and the fisheye distortion means every photo looks like a fisheye photo. That's great when you want it, annoying when you don't. For most shooters, a standard wide angle like a 12mm or 14mm prime would be more useful day to day. This is a second or third lens, not a first one.
