First Look: SIGMA 15mm F1.4 DG DN DIAGONAL FISHEYE Art Lens

Fisheye lenses are often viewed as a novelty. While some decent fisheyes have emerged over the years, the immense, 180-degree angle of view offered by these types of lenses often leads to poor image quality, whether from manufacturing challenges or simply because they aren’t really meant to knock anyone’s socks off. They get dusted off once in a great while, take a few wacky shots of the dog, then get dropped back on the shelf to be forgotten once again.

But the new SIGMA 15mm F1.4 DG DN DIAGONAL FISHEYE | Art is different… much different.

This lens takes the offbeat angle of view very seriously, and elevates the art of fisheye photography to a whole new level. Now, experiments are keepers. Throwaways become client quality. Wacky dog shots are… well, still wacky dog shots, but they look a heck of a lot better!

Whether you’re a filmmaker, astrophotographer, editorial photographer, or world traveler, this new lens is ready to elevate your fisheye fun to professional-level quality.

Introducing the 15mm F1.4 DG DN DIAGONAL FISHEYE | Art

Key Features of the 15mm F1.4 DG DN DIAGONAL FISHEYE | Art

The 15mm F1.4 DG DN DIAGONAL FISHEYE | Art is brimming with features, all of which are designed to provide the highest performance and the best user experience.

High resolution across the entire image, even at F1.4

Unlike most fisheye lenses, the SIGMA 15mm F1.4 utilizes the latest optical design that effectively corrects sagittal coma flare and other aberrations. This lens can precisely reproduce bright points of light across the whole frame even wide open, making it ideal for astrophotography.

180° angle of view that covers the entire frame

The main appeal of fisheye lenses is, of course, the extreme 180-degree angle of view and powerful distortion effect. The lens achieves this unique look while maintaining strict performance standards. As a diagonal fisheye, it also covers the entire image sensor, unlike a circular fisheye lens that produces a round image.

Minimized flare and ghosting

Wide-angle lenses often exhibit a lot of undesirable flare or ghosting when shooting in the direction of light sources. The SIGMA 15mm F1.4 offers unbeatable backlight resistance for clear and sharp images under any lighting conditions.

Astrophotographer-friendly features

Much like the SIGMA 14mm F1.4 DG DN | Art, this lens is packed with features that astro shooters appreciate. A manual focus lock, lens heater retainer, rear filter holder, special locking lens cap, and a durable Arca-Swiss tripod socket all make this lens perfect for a night under the stars.

HLA linear focusing motor

Fisheye SIGMA’s HLA (High-response Linear Actuator) yields fast and ultra-precise autofocus performance, which is a must when it comes to capturing fast action like skateboarding or parkour, and ideal for filmmaking, especially when tracking a subject.

Extremely durable construction

Premium build quality is true of any SIGMA lens, and the 15mm F1.4 is absolutely designed to perform in even the harshest conditions. Dust and splash resistance, water and oil-repellent front coating, and thermally stable composite parts all contribute to a seriously reliable piece of equipment.

Additional Features:

  • 21 elements in 15 groups
  • Aperture ring with click and lock switches
  • Customizable AFL button
  • 11-blade rounded diaphragm
  • High-precision, durable brass bayonet mount
  • “Made in Japan” craftsmanship

Image samples from SIGMA Ambassadors

A few SIGMA America Ambassadors were able to test out the 15mm F1.4 DG DN DIAGONAL FISHEYE | Art before its release, on both Sony and L-Mount camera systems. See what they thought about the lens in the following galleries!

Jack Fusco – Sony A7R V

The sharpness of this lens from edge to edge means capturing sweeping views of the night sky with pin sharp stars in the extreme corners, even shooting wide open.

From skate parks to dark sky parks, this lens unleashes a vintage fisheye experience with unmatched modern quality. The fast and highly precise autofocus on this lens makes it ideal for capturing action up close, while the F1.4 aperture and 180 degree field of view allows this lens to shine under the night sky.

Anabel DFlux – Panasonic Lumix S5 II

My shots are free from aberrations, flaring, and ghosting – a must for live concert photography. With so many different lights bouncing off of the glass, making sure my subjects remain clear is essential.

– Anabel DFlux, SIGMA America Ambassador

The detail reproduction on a full-frame camera is absolutely outstanding. All of the in-focus elements are crisp and clear, while the falloff a bigger apertures is smooth and feels very natural. Even the frame edges are gorgeous, saving me a lot of time in the editing room.

– Anabel DFlux, SIGMA America Ambassador

I love the results that come out of this optic my (living) subject’s proportions still look very flattering while retaining a wide field of view that really helps create a story in the image.

There’s never been a fisheye like it

In the end, the SIGMA 15mm F1.4 DG DN DIAGONAL FISHEYE | Art lens is both familiar and completely unprecedented. After all, there’s nothing new about the “look” of a fisheye lens, and most photographers have at least given one a try. But when a fisheye lens exceeds all your expectations, and continues to go above and beyond… that’s when you know you’ve found something special.
