Canon EOS 5DS & 5DS R Technical Review by Tony Northrup (and thoughts on lens resolution)

Tony Northrup does an exhaustive technical review of Canon’s new EOS 5DS and 5DS R (preview videos). There is a lot of talk about resolution and how much resolution modern lenses have. He does some math do compute a “perceptual resolution”, i.e. an approximate figure of an optic’s resolution, to get an idea on how well a given lens could do on the 5DS and 5DS R sensor.

Canon EOS 5DS Low ISO Dynamic Range up to 2 Stops Better Than EOS-1D X?

5ds

Some interesting (and yet unverified) news coming from people testing a pre-production EOS 5DS surfaced.

Northlight Images received a comment from a user testing a pre-production 5DS with DPP4. It appears that at low ISO the dynamic range of the EOS 5DS is 1.5-2 stops better than the [shoplink 4119]EOS-1D X[/shoplink], while high ISO performance (i.e. ISO 6400) falls slightly behind the [shoplink 22664]EOS 7D Mark II[/shoplink]. The same comment/rumor says the 5DS sensor is similar to the 7D2 sensor from a technological point of view (puzzles me), and that the 5DS sensor has been tuned to deliver the best possible low ISO performance.

Another comment says that the colour filter array of the EOS 5Ds is much closer to the [shoplink 271]EOS-1Ds Mark III[/shoplink] than to the EOS-1D X.

(CW3) Canon EOS C300 Mark II Coming With 4K?

C300 Firmware

Canon Rumors got word that the next iteration of the EOS C300, the EOS C300 Mark II might have 4k video recording on board. They write:

[the C300 Mark II will] be a bigger update than the EOS C100 Mark II was to its predecessor. We’re also told it’s going to be priced very aggressively, to better compete with Sony’s FS7 which is $7999 USD.

Rumors stating that Canon is going 4k are not new. Here at CW we heard the EOS 5D Mark IV will feature 4k.

Sigma 24mm f/1.4 DG HSM Art Lens Announced

Sigma Corporation of America Introduces New 24mm F1.4 DG HSM Art Lens at CP+ Imaging Show
Latest Global Vision Art lens offers highest-quality optical performance in its class

YOKOHAMA, Japan — February 10, 2015 – Sigma Corporation of America, a leading researcher, developer, manufacturer and service provider of some of the world’s most impressive lines of lenses, cameras and flashes, today announced the new Sigma 24mm F1.4 DG HSM Art lens, the ninth Global Vision lens to join the company’s iconic Art line-up. The announcement comes at the start of the CP+ Camera and Photo Imaging Show 2015, which begins on Feb. 12 in Yokohama, Japan.

The much anticipated 24mm F1.4 Art wide angle lens is designed for full-frame DSLRs, and when used on digital cameras with an APS-C size image sensor, it effectively becomes a 38mm. The lens is ideal for capturing a variety of photography subjects, including cityscapes, mountain ranges, astrophotography and weddings and is great for videography work as well. The 24mm also excels at indoor photography in low illumination thanks to the combination of exceptional focal plane sharpness, and gorgeous bokeh rendered by nine rounded aperture blades. The lens achieves a maximum magnification of 1:5.3 with a minimum focusing distance of 9.8 inches. The 24mm incorporates both “F” Low Dispersion (FLD) glass and Special Low Dispersion (SLD) glass in a design of 15 elements in 11 groups to minimize chromatic aberration of magnification especially in the edge of the image field. Moreover, the optimized power layout includes aspherical elements that are positioned in the rear of the lens for improved wide open performance. This helps to ensure minimal distortion through the correction of axial chromatic aberration and sagittal coma flare. The new lens element design also delivers excellent peripheral brightness.

“The Sigma Art lenses are recognized by photographers for world-class performance, and the new 24mm F1.4 DG HSM will be a significant contribution to our selection of fast aperture prime lenses which is quickly becoming a strong force in the industry” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “Sigma is redefining the expectations of fast-aperture full-frame prime lens performance, especially wide-open, and the results the 24mm F1.4 will deliver will be up to the exacting standards set by the 35mm F1.4 DG HSM and 50mm F1.4 DG HSM .”

Other updates to this lens include a new full-time manual focusing mechanism that switches to manual focusing, simply by rotating the focus ring, even when AF is being used, first introduced on the 50mm Art. This allows the photographer to make focus adjustments quickly and easily. As with all new lenses under the Global Vision categories, every 24mm will be tested using Sigma’s own MTF measuring system, “A1,” in the company’s factory in Japan.

Other lenses in the Art line include 35mm F1.4 DG HSM, 30mm F1.4 DC HSM, 18-35mm F1.8 DC HSM, 24-105mm F4 DG OS HSM, 50mm F1.4 DG HSM, 19mm F2.8 DN, 30mm F2.8 DN and 60mm F2.8 DN.

The 24mm F1.4 is compatible with Sigma’s USB dock, allowing photographers to update the lens’ firmware and change focus parameters as well as manual focus over-ride using Sigma’s Optimization Pro software. It is also compatible with Sigma’s Mount Conversion Service. The lens will be available in Canon, Nikon and Sigma mounts, and timing, pricing and availability will be announced at a later date.
