Now it is official after having been rumored for a while: Adobe released Lightroom for the iPad as part of the Photoshop Photography Program ($9.99 per month, includes Lightroom and Photoshop). There are also updates for Lightroom (rel. 5.4 – Mac | Win) and Adobe DNG Converter (rel. 8.4 – Mac | Win).
More videos after the break.
After having reported the Canon EOS-1D X’s auto-focus issue in cold weather, an information taken from a Canon internal document, Canon Rumors claims to have more such documents, and these documents apparently show that Canon is charging for repairs of known issues or design flaws of their gear.
According to the cited source, Canon knows about
a couple of lenses with design flaws and Canon is charging $250-$450 for these repairs out of warranty and not fully disclosing the design flaw to the customer.
Which, in plain words, means that Canon may charge you for repairs that are out of warranty for gear that has a known design flaw.
I don’t know what to think about that. If true, and worse: if proven, that Canon did not disclose design flaws and even charges for the repair of such issue, it could hit customers confidence in what the Canon brand name represents. Consider that these issues concern high-end gear as the EOS-1D X, which doesn’t exactly cost a handful of peanuts. The debate if Canon Rumors should or not post the documents they say to have is still going on here.
The Sigma 50mm f/1.4 Art seems to hold up to the hype and the expectations. They compared the Sigma with Canon’s 50mm f/1.2L lens (price & specs), among other lenses like the Nikon 58mm f/1.4G AF-S Nikkor, and, when it comes to sharpness, the Sigma 50mm f/1.4
sharpness holds up very well against this competition. At f/1.4 and on a full-frame camera, it pretty well blows all of the others out of the water. The Canon 50/1.2L is pretty sharp in the center, but the corners are extremely soft.
The other lenses all improve at f/2, but so does the Sigma 50, easily bettering all the others, at every point across the frame. At f/2.8, the Sigma’s blur characteristic is almost perfectly flat, and quite sharp everywhere.
Chromatic aberrations are quite well controlled in the Sigma 50mm f/1.4 and vignetting is lower than on the Canon. And what about distortion? The Sigma has an almost immeasurable geometric distortion. The Sigma 50mm is
very well built, making use of their Thermally Stable Composite material, that despite technically being a form of polycarbonate plastic, looks and feels more like metal (and shares similar thermal properties to aluminum, as well)
The Sigma 50mm f/1.4 Art is the most exciting lens we’re likely to review this year. All competing lenses from Canon and Nikon fell short when compared to the resolving power of the 50mm Art. We haven’t (yet) tested the very best from Zeiss, but we are confident Sigma will trounce it in one key area: price. This difference is likely to be a yawning chasm. Our expectation for pricing on this lens is for something at least a bit less than Canon’s 50mm f/1.2 L, which goes for $1,700; despite a variety of rumors and no official price for the Sigma yet, we’re expecting it’ll be less than that.
I think this is the very first full review of the Sigma 50mm f/1.4 DG HSM “Art” lens, and it is definitely worth to be studied. Test charts and sample pics are included.
It appears Sigma is about to launch another awesome lens, one that could be more outstanding even than the Sigma 18-35mm f/1.8 DC HSM (price & specs) and the Sigma 35mm f/1.4 DG HSM (price & specs), two of Sigma’s new lenses that are highly regarded by the community. We have just to wait to know the price
Have a great sunday!
