Lenstip reviewed the Sigma 18-35mm f/1.8 DC HSM lens, the UFO: Unbelievable F-stop Object. As you most probably know if you live on this planet, the Sigma 18-35mm f/1.8 is the first zoom lens for APS-C DSLR to deliver constant f/1.8 over the whole zoom range. As if that wasn’t amazing enough, Sigma managed to give a more than fair price to this lens: $799, while most people was expecting a price tag at least over $1000. So, the suspect was Sigma could have had to make some compromises on some aspects of the lens. Nope. The featured review shows once more how outstanding the Sigma 18-35mm f/1.8 is. Read more after the break.

Another review that assesses how awesome the SIgma 18-35mm f/1.8 DC HSM lens is. ephotozine reviewed Sigma’s latest addition to their “Art” line-up, and say:

This lens opens new possibilities for owners of APS-C format cameras for low light shooting and creative use of depth of field with a fast f/1.8 maximum aperture, normally reserved for prime focal length lenses. The image quality delivered, especially at shorter focal lengths is of the level normally reserved for prime lenses also.

Jaron Schneider over at fstoppers reviewed the latest addition to Sigma’s “ART” line-up, the awesome Sigma 18-35mm f/1.8 DC HSM lens, the world’s first zoom lens for APS-C DSLRs that has a constant f/1.8 over the zoom range. And at a really competitive price, $799/€999. They used a Canon EOS 60D for the test. Some excerpts from Jaron’s review:

• […] this lens is beautiful […] a gorgeous blend of metal and rubber with only a few plastic parts
• […] the autofocus works […] very well in daylight. It’s fast and, generally speaking, very accurate
• At night, the lens is a bit less accurate, but it correctly focused (in nearly pure darkness) ten out of thirteen times
• Chromatic aberration is extremely well controlled in this lens
• Flaring is decently controlled at most apertures
• […] sharp at all focal lengths and apertures
• For Sigma’s first run at a previously never before seen lens concept, this is a rousing success.
• This is so far Sigma’s best APS-C only lens, and it’s the best by leaps and bounds

DigitalCamera Review posted some sample pics shot with the awesome Sigma 18-35mm f/1.8 on a Canon Rebel T5i (EOS 700D). No post-processing applied, and, if I got it right, a production model of the lens was used. The sample pics can be viewed in full resolution.
