Comparison: Canon EF 24-105 f/4L IS vs Sigma 24-105 f/4 DG OS

Comparison: Canon EF 24-105 f/4L IS vs Sigma 24-105 f/4 DG OS

Roger at LensRentals.com has completed his comparison of the Canon EF 24-105 f/4L IS and the Sigma 24-105 f/4 DG OS.

Lots of people ask us which lens to buy and we usually say get the one for the best price, which for the last few months has been the Canon variant. While the Sigma is a very good lens, it’s not head and shoulders above the Canon by most accounts, if at all.

Says Roger
“Sigma has made a very nice zoom here at a very good price. It’s obviously not going to create the stir that occurred with their 35mm f/1.4 or 18-35 f/1.8 lenses, but it’s a nice addition to their lineup.

Canon shooters who have a 24-105 f/4 IS have no reason to change based on optics as long as the promotional pricing remains in effect. The Sigma and Canon 24-105s are nearly identical. Similarly the Nikon 24-120 has been available on discount lately, so I don’t see a big motivation for Nikon shooters to change, either.

Of course, if the pricing changes I wouldn’t hesitate to buy the Sigma instead of the name brands. If nothing else, I think the presence of the Sigma will keep Canon and Nikon prices reasonable.

I expect as this lens is released in other mounts it will be quite popular. There’s a reason Canon has sold about 3 gazillion 24-105s. It’s a very good lens with a very useful range. The Sigma will be available for Sony shooters next month and may be the best option in that mount.” Read the full review

Review – Sigma 24-105mm f/4 DG OS

Review – Sigma 24-105mm f/4 DG OS

Justin has completed our review of the Sigma 24-105mm f/4 OS. As expected, the lens is a real winner when compered to the Canon equivalent and is priced exceptionally well. Sigma’s quality, warranty and pricing are going to ensure that they’re worth your consideration at certain focal lengths.

Says Justin
“My opening line said it all: Sigma is absolutely killing it with these new lenses. They perform, look and are priced better than the Canon equivalents. …….. Their attention to industrial design and optics makes me think more of the even higher-end Zeiss lenses than it does a Canon, which is smart, because the cost difference between a Zeiss lens and Sigma is even greater, creating an even more compelling price gap in Sigma’s favour.”

DXOMark: Sigma 24-105 f/4 DG OS Reviewed

From DXOMark
The folks at DXOMark have completed their review and testing of the new Sigma 24-105 f/4 DG OS Art series zoom lens.

Says DXOMark
“Given its popularity, Canon has been slow to replace the EF24-105mm f4L IS USM, and it has provided rival Sigma with the opportunity to gain some leverage in this highly competitive sector. Sigma are sure to be rewarded as it’s not only a superb performer optically, at $899 it comfortably undercuts the Canon and is well worth taking a closer look.”

Review: Sigma 24-105 f/4 DG OS

From The-Digital-Picture
Bryan at The Digital Picture has completed his review of the new Sigma 24-105 f/4 DG OS Art series lens. This lens retails for around $899 USD, and by the looks of the review, that’s a bargain of a price. This lens has already begun shipping for the Canon mount.

Says Bryan
“I’ve tested a lot of lenses that made me anxious to move on. This is not one of them. I would have no problem making this my primary general purpose lens.

The Sigma 24-105mm f/4.0 DG OS HSM Art Lens’ long focal length range will take a broad swath out of your angle of view needs. This great-looking lens is a joy to use and the results from it are even exciting to view. For a reasonable price, the Sigma 24-105mm f/4.0 DG OS HSM Art Lens reliably delivers the excellent image quality you are looking for from your DSLR camera.”

Sigma 24-105mm f/4 DG OS Art Officially Official

Sigma 24-105mm f/4 DG OS Art Officially Official

….. and one more try
Sigma has officially announced the 24-105mm f/4 DG OS Art series lens.

RONKONKOMA, NY — October 16, 2013 — 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 its newest addition to the Sigma Art line of lenses for full-frame cameras, the 24-105mm F4 DG OS HSM.

True to its categorization as a Sigma Art lens, the new 24-105mm F4 DG OS HSM is designed for artistic expression and top-notch image quality. This versatile lens covers the basic shooting range from wide to medium tele with an inner focusing system that eliminates front lens rotation, enhancing the lens stability and allowing the use of circular polarizing filters. It also boasts a constant aperture of F4, and contains Sigma’s proprietary Optical Stabilizer (OS) technology to compensate for camera shake. Moreover, it was designed to surpass the required quality inspection of every Global Vision lens with Sigma’s own modulation transfer function (MTF) “A1” measuring system to create new optical standard to align with the high-spec cameras on today’s market.

“For many years, Sigma users have been seeking a standard zoom lens in this range,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “The 24-105mm F4 DG OS HSM is yet another example of Sigma listening to its users and delivering new and innovative products with the highest image quality.”

Amir-Hamzeh added that this new lens combines the largest possible fixed aperture to zoom ratio that will maintain optimal integrity for many kinds of photography, including landscapes, architecture, portraiture and still-life. With a minimum focusing distance of 45cm and a maximum magnification ratio of 1:4.6, this lens is also excellent for close-up photography.

High-performance glass elements, including SLD, FLD, which is equal to fluorite, and glass-molded single- and double-sided aspheric lenses have been included into the optical system to prevent aberration, field curvature, distortions and color aberration. The 24-105mm F4 DG OS HSM lens is also able to suppress chromatic aberration very effectively at the telephoto-end, and can achieve superior image quality throughout the zoom range. Unlike lenses with similar specifications, this lens overcomes low peripheral brightness. Although it is designed for full frame cameras, it also works with APS-C sensors, giving an increase to focal length.

The lens’ Hyper Sonic Motor (HSM) ensures a silent, high-speed auto focus function and enables full-time manual focusing capability. The 24-105mm is also compatible with Sigma’s USB dock allowing photographers to update its firmware and change focus parameters using Sigma’s Optimization Pro software. It is also compatible with Sigma’s recently announced Mount Conversion Service.
