More Sigma 50mm f/1.4 Art Real-World Sample Pics (dpreview)

Sigma 50mm f/1.4 Art

Dpreview published a set of 41 real-world sample pics shot with the Sigma 50mm f/1.4 DG HSM Art lens. Interestingly, the Sigma was used with a Canon EOS 5D Mark II (yes, not Mark III). Seems weird to me considering the exceptional optical performance of the Sigma.

The hot news of the day is DxOMark’s test of the Sigma 50mm f/1.4 DG HSM Art lens, and how it compares to the four times pricier Zeiss Otus 55mm f/1.4 (this time using an EOS Mark III). Well, the Sigma comes seriously close to the Zeiss.

Pre-orders for the Sigma 50mm f/1.4 DG HSM can be made at B&H Photo and Adorama.

DxOMark Confirms Sigma 50mm f/1.4 Art Performs Very Close To Zeiss 55mm f/1.4

With all this hype about Sigma’s new 50mm f/1.4 DG HSM “Art” lens, it’s fine to see that also DxOMark confirms the exceptional optical properties of this lens, and that it can hold up to the Zeiss Otus 55mm f/1.4 – a lens you have to pay $4,000. And now compare that to the $949 that you have to pay for the Sigma 50mm f/1.4 Art lens. And then: the Zeiss is manual-focusing, the Sigma has auto-focus. Pre-orders for the Sigma 50mm f/1.4 “Art” lens can be made at B&H Photo and Adorama, stocks are limited for the time being.

The Sigma scored 35 vs the 38 of the Zeiss. Says DxOMark about the comparison between the two lenses:

[...] the extreme performance of the Zeiss is noticeable in some subtle ways. At wider apertures, the Art lens can’t quite match the sharpness of the Zeiss in the outer field but that won’t be a concern for all but the most fastidious of users.

At f2 the Sigma is almost on a par with the Zeiss, only it can’t quite match the Zeiss in the corners – though the difference in real world terms is trivial. The new Sigma can boast of slightly better control of vignetting and, arguably, chromatic aberration at maximum aperture, though there’s some fringing evident in the extreme corners.

Not bad for a lens that costs a fourth of the Zeiss :-)

Canon Powershot G1 X Mark II First Impression Review (DPreview)

Powershot G1 X Mark II

DPreview posted a first impression review of the Canon Powershot G1 X Mark II. The review isn’t entirely positive, have a look in the “shooting experience” section of the review. Among other notes, the reviewer writes:

The camera can certainly be held with one hand, though I preferred the more solid feel of the ‘custom grip’. There are a lot of buttons that surround the thumb rest so you have to be careful, as some buttons can be easy to bump. Speaking of buttons, I found myself scratching my head as to why there are two Wi-Fi-related buttons, and I kept pressing the upper one thinking it was for playback mode. [...]

In nearly all situations, the autofocus system performed admirably. While I wasn’t blown away by its speed, I didn’t have to wait for it to lock on its subject

About the built-in WiFi:

Some manufacturers do better than others when it comes to setting up Wi-Fi, and Canon is one of the worst. To be brief, the Image Gateway website leaves much to be desired, there are too many steps required, and the camera takes a long time to connect to a network. The bottom line is that Canon’s Wi-Fi feature, while comprehensive, could be a lot more user-friendly.

I agree about how poorly Canon integrates WiFi functionality in their cameras. This could definitely be done better, and more user friendly.

Alternative Tripod Mount Socket For Canon Tele-Zooms (200-400mm, 400mm, 500mm, 600mm)

Tripod Mount

Above: Canon original tripod mount – Below: Berlebach’s tripod mount (image courtesy of photoscala.de)

German manufacturer Berlebach offers an alternative tripod mount socket for Canon’s EF 200-400 f/4 (price & specs), EF 400mm f/2.8 (price & specs), EF 500mm f/4 (price & specs), and EF 600mm f/4 (price & specs) lenses.

Berlebach’s tripod mount is more compact than the original one and should also reduce vibrations.

Press release (machine translated):

Canon Telephoto Adapter Berlebach

Berlebach ® Stativtechnik in Mulda has developed a compact foot for tripod mounting of telephoto lenses from Canon, on the one hand have been much smaller than the original foot and on the other hand, allows the use of UniQ / C and Arca Swiss-compatible quick-change systems. The price of the Tele-adapter is (RRP including VAT) EUR 49.

With the telephoto adapters for Canon 400/600 mm ( http://www.berlebach.de/?bereich=details&id=514 ) and the original Berlebach-release plates are the Canon telephoto lenses 4,0 / 200-400; 2,8 / 400; 4,0 / 500 4,0 / 600 on all UniQ/C- and Arca Swiss-compatible quick-change systems usable. The replacement of the original foot-flung through the telephoto adapters Berlebach with its considerably thinner design reduces space requirements, which can be the Canon telephoto lenses pack much easier for transport. In addition, possible oscillations are determined by the compactly built Adapter Berlebach significantly reduced and improved handling achieved by an optimized center of gravity.

To use the adapter, the four screws securing the original Canon-foot must be solved with an M3 hex wrench. With the same screws Berlebach adapter is then fastened to the lens. After the release plate with two 1/4 “or a central 3/8″ Münzschlitzschraube (s) is fastened to the adapter. When using an original Berlebach-release plate adapter accesses as in the profile of the plate so that the combination can be completely rotationally fixed to the axis of the lens on a tripod head. Depending on the length of the release plate, this is for balancing both when mounted on the adapter, as well as the respective position in the quick-change system according to forward and backward movable. When using AC drives from other manufacturers may result in restrictions on the twisting safety.
