Venus Optics Releases 4mm f/2.8 Fisheye Lens with 210° Field of View

Venus Optics has been slowly releasing the four lenses it teased back in April of 2018. We saw the 10-18mm f/4.5-5.6 for Sony E-Mount in October, the 100mm 2x Macro for full-frame DSLRs in June, and the 17mm f/4 Zero-D for Fuji GFX earlier this month. Today, they're officially releasing the last lens: the Laowa 4mm f/2.8 Circular Fisheye for Micro Four Thirds systems.

This Widest-Ever 4.9mm Fisheye Lens Can See Behind Itself

LensRentals founder Roger Cicala is known for disassembling camera gear and sharing his findings on his company blog. Now he has done the opposite: he's sharing how he built (from scratch) a prototype 4.9mm f/3.5 "hyperfisheye" lens, the widest fisheye lens ever made. It's a lens so wide that it can literally see behind itself.

7 Reasons Why Fisheye Lenses Are Awesome

Fisheye lenses are often considered a ‘no-no’ among professional landscape and cityscape photographers. People see them as not much more than a gimmick. I often hear complaints about fisheye lenses because of ‘that ugly distortion’.

These Street Portraits Were Shot From Below with an Ultra-Wide 8mm Lens

Street photographer Willem Jonkers often hits the streets of Rotterdam in the Netherlands with an ultra-wide-angle 8mm fisheye lens. He then approaches strangers and gets not only close, but low -- really low.

His collection of ultra-low, ultra-wide street portraits show a "Gulliver" effect that makes his subjects look like enormous giants towering over each scene.

Shooting Full Image Circles with a 180° Fisheye Lens

Photographer Mathieu Stern did this short experiment with capturing the full image circle from a 180-degree fisheye lens. You'll need a smaller image circle on a larger camera sensor. For this video, Stern used a Kenko 180° fisheye lens, screwed onto a 55mm to 52mm filter, screwed onto a Canon 50mm f/1.4 FD lens, screwed onto a NEX adapter, mounted to the Sony a7II.

Beauty and Symmetry Collide in Stunning Photographs of Mosque Architecture

Mohammad Reza Domiri Ganji is a 23-year-old physics student at Mazandaran University, and yet, you've probably seen his photography floating around the Internet as of late.

That's because, when he's not studying, Ganji is capturing truly stunning photographs of the colorful, architecturally gorgeous interiors of historical Mosques throughout the Middle East.

DIY Hack: Add a 3-Stop ND Filter to Super Curved Fisheye Lenses

The Rokinon 8mm f/2.8 lens is one of the best options for photographers wanting to get in on the super-wide-angle action with as little of an investment as possible.

One problem with this lens, however -- and it's the same with most fisheye lenses -- is the curved front element. With such a dramatic curve, the use of filters on such a lens is almost impossible... almost.
