01 Oct

Leica has announced the Elmarit-S 45 mm f/2.8 ASPH lens for its medium format S system. With an angle of view equivalent to a 35mm lens on full frame, it offers a classic moderate wide-angle field of view. Like several of the other S lenses it’ll be available in two versions, either with or without an in-lens ‘Central Shutter’ (that allows flash sync at all shutter speeds). At the same time, Leica is offering firmware updates for its S, S2 and S2-P cameras to give ‘optimum functionality’ with the lens. The Elmarit-S 45 mm f/2.8 ASPH will be in dealers this month at a price of £4650, or £5500 for the CS model.

Roger Cicala investigates accuracy of lens adapters

30 Sep

Mount adapters are incredibly useful for their ability to make lenses from one manufacturer usable with camera bodies from another. But do they have any impact on image quality? LensRentals’ Roger Cicala, not one to take manufacturer’s claims at face value, investigated. Knowing that slight mis-alignments between a lens and even its native mount can cause softness in images, the added complexity with a lens adapter in the mix seemed likely to cause more problems. His findings are indeed interesting.

Miniature wide angle lens under development at UCSD

28 Sep

UCSD.jpg

Researchers at UCSD’s Jacobs School of Engineering are working on a miniature wide angle lens, taking advantage of the benefits of spherical lenses. At just a tenth of the size of a traditional wide angle lens, a spherical lens can create wide angle images without chromatic aberration or loss of resolution at corners. The challenge is capturing the lens’ spherical projection on a flat sensor. The team have overcome this by using optical fibers fused to the rear of the lens to relay light to electronic sensors. Click through to read more about the this unique concept.

The ever-increasing video capability of digital SLRs has seen manufacturers such as Canon, Samyang and Zeiss make video-optimised versions of their conventional lenses, and now Kenko Tokina is getting in on the act. The Tokina 16-28mm T3.0 is a manual focus version of the AT-X 16-28mm f/2.8 Pro FX wideangle zoom, with a redesigned barrel that features the usual refinements for video work, including geared focus, zoom and aperture rings, and scales designed to be read from the side of the camera. It’ll be made in Canon EF and Arri PL mounts, with a suggested retail price of ¥580,000 – almost 5 times that of lens it’s based on.

31 Aug

[ By Delana in Gadgets & Geekery & Technology. ]

Taking photos on our mobile phones has become a daily activity for a lot of us, but getting really high-quality pictures usually requires some kind of clunky add-on lens and a special app. Taking macro pics on your mobile device is made super-simple by the Easy-Macro Smartphone Lens.

Created by Adam Hicks, the Easy-Macro is a macro lens that fits right over the built-in lens of your device. It fits any phone or tablet thanks to its super-stretchy band. The small lens provides 4X magnification and requires nothing more than just stretching onto your device.

The device is composed of a simple lens and a band that holds it onto your device. It fits everything from a thin 4th generation iPod Touch to a big iPad. No software is needed to make the lens magnify your target subject, so it can be used with any device an any operating system.

The results are surprisingly high-quality, especially for such a simple device. The lens can capture the tiniest details and create some very impressive ultra-close-ups. The company had been producing the lenses for several years before turning to Kickstarter for help bringing the production back to the US from China.

Canon has released a version of its EF-S 55-250mm F4-5.6 lens that uses its STM stepping motor. STM lenses are designed for movie recording, with the goal of providing smooth and silent focusing. Unlike its predecessor, the STM version of the 55-250 has internal focusing. You’ll be able to pick up the 55-250 STM lens in late September for $ 350. It’s also a safe bet that the 55-250 STM will come bundled with Canon DSLRs in the near future.

8 August, Zeiss 135mm f/2 APO Sonnar – The World’s Best Lens?

08 Aug

There are a number of truly great lenses on the market, but with the new Zeiss 135mm f/2 APO Sonnar may have outdone even themselves. 

"Having been to Antarctica with Michael and Kevin, I would say after having traveled the world and shot nearly my entire life as an exhibiting photographer,  it was one of my highlights in my life and I talk about it, all the time.  The images and experience of seeing something visionary and nearly extinct from the world, to see and experience the wildlife and scenery that does not fear humans is amazing.  The images I shot there won me two Smithsonian awards and nearly 18 other international awards". – Tim Wolcott
