Sigma 18-300mm C

• Sigma has confirmed the upcoming release of the 18-300 f/3.5-6.3 DC OS HSM Contemporary for Canon, Nikon and Sigma cameras (read the statement). Unlike the 150-600mm Sports, this lens should not suffer from any shortage…


Sigma macro lens for 18-300mm Contemporary

• The AML 72-01 close-up lens, that enables to reach 1:2 magnification ratio with the above lens, can be pre-ordered at B&H Photo.

This lens features an apochromatic design and maintains the original lens’ quality throughout the zoom range from 80mm to 300mm focal length positions. When in use, the minimum focusing distance of 15.4″, and 5.5″ working distance, is retained.

Judging by the expected magnification ratio of 1:2 magnification in combination with the 18-300mm C, this magnifying glass seems to be relatively weak (1 diopter?), which also means that it should affect image quality only very mildly.

Of course, it can be used with any lens that sports a 72mm filter thread, but as any close-up filter, it is better matched to telephoto lenses. For instance, a maximum reproduction ratio of around 1.3:1 can be obtained by pairing it to the Sigma 150mm f/2.8 DG (OS) HSM Macro (1:1 natively).

Delivery delays expected for the Sigma 150-600mm telephoto zoom lens

Pre-order the Sigma 150-600mm f/5-6.3 DG OS HSM Sports: Adorama | B&H Photo | Amazon US | More options

Sigma has posted a notice (English translation) regarding the availability of the Sigma 150-600mm f/5-6.3 Sports.

While the lens will start shipping on October 24th, initial supply will be too low to satisfy the higher-than-expected demand. The first batches will serve to fulfill pre-orders until production catches up, so we may not see it in stock for a while.

The new Sigma products will be released soon

The dp1 Quattro, 150-600mm f/5-6.3 Sports lens, new teleconverters and filters will be available starting October 24th in Japan, and “towards the end of this month” in the rest of the world, says Sigma Japan. No word on the 18-300mm f/3.5-6.3 Contemporary.

Some doubt remains about the worldwide release of the dp1 Quattro, since availability info is missing from the English page (see link below). Probably just an omission.

The release of Sigma Photo Pro 6.1 is also scheduled for October, so it should come with the camera.

Foveon imaging chip

Back in 2012, Foveon Inc. (owned by Sigma) filed a patent for a solution to get the most out of the sensor’s dynamic range. This technology doesn’t seem to have made its way into the Quattro series.

The inventor, Lukac Rastislav, is “senior digital imaging scientist at Foveon, Inc. / Sigma Corp”  (Source).

Method of adjusting the brightness of a digital camera image (published September 16, 2014)


A method for adjusting the brightness of a captured image from a digital camera includes calculating a reference exposure value using the capture parameters and calculating an actual exposure value as a function of ambient illumination parameters.

Sigma's answer to Tamron's 150-600mm lens

Sigma is still coy about the 150-600mm f/5-6.3 Contemporary lens. People lusting after it have to settle with a spec list.

Thanks to reader Evie, who inquired with Sigma UK, for sharing the following tidbits with us:

  • There is a 50/50 chance to see the lens hit the shelves before Christmas.
  • Weight will be around 1.8 kg / 63.5 oz (the Tamron weighs in at 1.95 kg / 68.8 oz).
  • Unsurprisingly, price will be similar to the Tamron’s, maybe slightly higher.
  • Compared to the Tamron lens, image quality will be “similar or slightly better”, admittedly with some amount of “edge softness” wide open.
  • The first production batch is expected to be limited in quantity.
