7Artisans unveils range of low cost, fast lenses for mirrorless cameras

by on Jul.10, 2017, under Reviews

Chinese optical manufacturer 7Artisans has introduced a collection of four lenses that are intended to provide low-cost alternatives to branded optics. The lenses are all designed for mirrorless cameras, and the company intermittently provides mounts for Sony E, MFT, Fujifilm X and Canon EOS M users, as well as one lens for Leica M cameras.

The lenses are all manual focus, feature a copper core with an aluminum exterior and some of them come in a choice of black or silver finish. There isn’t much information on the company website but the Amazon sales pages reveal some of their specification.

25mm f/1.8 | Sony E/Fujifilm X/MFT | $70

This lens was designed for APS-C and Micro Four Thirds sensors, and boasts an aperture range of f/1.8-16. It uses seven elements in five groups, has 12 iris blades and offers a 46mm filter thread.

35mm f/2 | Sony E/Fujifilm X/Canon EOS M | $156

A lens capable of covering a full frame sensor, this 35mm f/2 uses a 10-bladed iris and has a minimum aperture of f/16. It is constructed with seven elements arranged in five groups and offers a 43mm filter thread.

50mm f/1.1 | Leica M | $369

Designed for the Leica M family, this standard focal length uses 12 iris blades to form its click-less f/1.1- f/16 aperture range. The company says it has used a Sonnar design and high-refractive index glass to optimize the lens for use at the widest apertures. The lens has seven elements arranged in six groups.

The current version isn’t compatible with the Leica M4 and M4A, but models from September onward will be.

7.5mm f/2.8 | Sony E/Fujifilm X/MFT | $139

This is a fisheye lens that the company claims offers a maximum angle of view of 180°. It has 11 elements that are arranged in eight groups, and the 12-bladed iris closes to f/22.

Haunting photos from inside the wrecked cruise ship Costa Concordia

by on Jul.09, 2017, under Reviews

In August of 2014—two years and seven months after the cruise ship the Costa Concordia sank off the coast of the Tuscan island Giglio, claiming 32 lives—photographer Jonathan Danko Kielkowski swam aboard to document what was left.

At that point, the ship had only recently been raised from the bottom of the ocean, having spend two and a half years partially submerged—a home for sea life and wild superstitions about how its sinking was some sort of omen. After all, it did sink almost exactly 100 years after the Titanic.

But Kielkowski wasn’t going there to document fantasy. He wanted to capture raw, abandoned, decrepit reality.

To his credit, when the ship arrived in Genoa to be scrapped, Kielkowski tried to get a permit and capture the photos legally. But a permit was impossible to acquire, and after being turned back by the Coast Guard once, he tells DIYP he finally succeeded in swimming to the ship in the dark, camera gear and clothes towed along in a small rubber dinghy.

He got in, set up, and once the sun came up he got to shooting. Using his Canon 5D Mark II with a EF 16-35mm F2.8 attached and a small, sturdy tripod, he wandered around the wreck for 6 hours and captured some 500 photos.

“It was pitch black inside the wreck and most parts of the ship had no lights installed at that time,” he wrote in response to one photographer’s criticism, explaining how the photos were captured. “The expose time for most of the images is well over 5 minutes.”

Technique aside, for Kielkowski, those photos provide a distant echo of the nightmarish fear 4,000 passengers must have felt as they tried to evacuate a sinking ship.

The photos above and many others besides were eventually collected into a photo book, Concordia, published by White Press. To learn more about or order the book, visit this link. And if you’d like to see more of Jonathan’s work, visit his website or give him a follow on Facebook and Instagram.

DIYer adds giant heat sink to overheating Lumix GF7 camera

by on Jul.08, 2017, under Reviews

One industrious Lumix GF7 owner named Eric Strebel has solved his camera’s overheating issue with a pretty intense DIY hack. Namely, he added a massive heat sink to the back of the camera…. problem solved.

The entire hacking process is detailed in a video that Strebel uploaded to YouTube, where he explains that his camera would, at times, warn him to let it cool down due to overheating while shooting video. The heat sink, which is attached to the camera using piano wire, is very effective at keeping the camera cool for long recording sessions.

The GF7 features a hinged display that can be flipped up, leaving the back of the camera flat and exposed. It is on that portion of the camera that Strebel mounted the heat sink, which he harvested from an old PC. A drill press was used to machine the heat sink to size, while piano wire was bent and utilized as a removable attachment point for mounting the heat sink onto the camera.

The entire project, explains Strebel, took about 4 hours to complete.
