10 Jul

Chinese manufacturer SainSonic, which also makes an 8mm F3.0 fisheye prime lens as well as various floating music orbs and tabletop tube headphone amplifiers, has announced a new manual focus lens for APS-C cameras. It’s called the Kamlan 50mm F1.1 (!) lens and it’s currently offered in Sony E-Mount and Canon EOS M mounts, with a Fujifilm mount version coming soon.

The lens has a claimed 11 circular aperture blades (claimed, because if you were to count the blades in the above mockup, you’d wind up with 9), and a fairly pedestrian five elements in five groups, though there’s talk of high quality element coatings.

You can snag a Kamlan 50mm F1.1 today for the very reasonable price of $ 169.99 USD.

Even the most elusive high-frequency details are within the scope of Sigma’s quality control inspections. Every Global Vision lens is A1 tested, analyzed and approved before leaving the factory ensuring maximum performance out of the box.

Rumors hint at super-fast Sigma 50-100mm F1.8 Art lens for APS-C DSLRs

20 Feb

Rumors suggest Sigma is getting ready to launch a 50-100mm F1.8 lens for APS-C cameras. Full specifications and convincing images of the lens have been leaked, suggesting the lens will be part of the company’s impressive ‘Art’ range. Such a lens would offer a fast partner to the company’s 18-35mm F1.8 Art lens, giving the same angle-of-view, depth-of-field and total light gathering capability as a ~75-150mm F2.8 lens on full-frame.

Specifications reported on Digicame-info.com seem plausible, so we’re looking forward to next week’s CP+ show in Yokohama, Japan, to see if the rumors are true. We’ll be reporting from the show, so stay tuned for all the details.

Lens construction (elements/groups) 21/15
Filter size 82
Minimum focus distance 95cm
Aperture blades 9
Length 170.7mm (mount not specified)
Diameter 93.5mm
Weight 1490g

 The site suggests a price of ¥167,400 (~$ 1500) and a launch date of April 22nd.

Pocketable APS-C: Fujifilm X70 real-world samples

09 Feb

Fujifilm’s new X70 compact camera puts the 16MP APS-C sensor from the X100T into a much smaller body, omitting an EVF but adding a 28mm equiv. F2.8 lens and articulating touch-sensitive screen. The X70 is certainly one of the nicest compact cameras to look at, and its specifications are pretty impressive, but what kind of images can it produce? We spent the weekend shooting with a production-quality camera.
