A Canon Rumors reader “JerseyShooter” has been working with Sigma to improve the performance with Canon’s APS-H flagship cameras, the EOS-1D Mark III & EOS-1D Mark IV.
Back in October of 2013, JerseyShooter started a blog documenting the issues he was having with the lens on a blog. He worked directly with Sigma and it looks like it has paid off with the firmware that was released yesterday to improve the performance with both of the mentioned cameras.
There have been other issues with the lens that he is documenting on the blog as well.
For the record, JerseyShooter is an employed professional photographer.

I have finally purchased the Zeiss Distagon T* 15mm f/2.8 and will be putting it through paces on a two week trip to Namibia beginning on April 6. For filters, I’ll be using the Sigma 95mm DG Circular Polarizer, as well as large Singh-Ray grads when needed.
My immediate first impressions are quite good, amazing build quality, great zoom ring and the silly test shots looks terrific. I’ll be shooting exclusively with the EOS 6D on this trip.
Justin has received the Sigma 120-300 f/2.8 DG OS for review and he’ll be putting it through the paces with the EOS-1D X. He’s already shocked at the size and weight of the lens. No, it’s not a “hand holding” lens for most people. The first 2 negatives you can give the lens is the heavy and unnecessary metal lens hood and the equally enormous tripod foot. Third party accessory makers could surely knock a pound off the lens replacing both parts with lighter weight materials.
Optically and AF wise the lens is very good with initial test shots, Justin has the USB dock and will also put that through its paces.
Both reviews should be online some time in April, though I’ll be posting images from the Zeiss 15mm as the trip progresses.

Bryan over at TDP has completed his review of the new Sigma 120-300mm f/2.8 DG OS HSM lens.
Bryan, just like a friend of mine that is sponsored by Sigma in Canada, was pleasantly surprised about how much they like the lens. I keep hearing the build quality, optical quality and focal range are very useful on a day-to-day basis.
“It is hard not to like a great looking lens with a 120-300mm focal length range in a non-extending, solidly built body that also feels great – and delivers image quality that leaves most other zoom lenses wanting even at this lens’ wide max f/2.8 aperture. I like the direction Sigma has been going with their recent lenses and I think they have another hit with the Sigma 120-300mm f/2.8 DG OS HSM Lens.”

SIGMA 120-300mm F2.8 DG OS HSM
Conventionally, large aperture lenses for 300mm F2.8 have been loved by professional users due to their brilliant capability of depiction and bright aperture value. It has established a solid standpoint in the world of photography. Based on the concept that turning a 300mm F2.8 lens into zoom lens would enable photographers to expand the scope of shooting, we have developed 120-300mm F2.8 lenses and released them into the market. It is not simple to decide on a composition with a 300mm lens. Especially for sports and theatrical shows, shooting positions are almost always fixed and changing lenses could lead to missed photographs. By adding a zoom function with the large aperture 300mm F2.8 lens, it no longer requires other interchangeable lenses and rotation of the zoom ring will offer excellent framing. In other words, when conditions are difficult, this high-performance lens gives you more scope to express yourself in the shots you take.

1. Sports line lenses deliver high action-capture performance
Sigma is organizing all its interchangeable lenses into three product lines; Contemporary, Art and Sports. While offering sophisticated optical performance and expressiveness, our Sports line lenses deliver high action-capture performance, enabling photographers to get exactly the shots they want. With their high-level optical performance and expressive power, these lenses can capture fast-moving subjects, even at distance. This high-performance line also offers a variety of functions to aid the photographer in challenging conditions and scenarios. The SIGMA 120-300mm F2.8 DG OS HSM is the first product from the “Sports” line. Besides sports photography, the lenses are also perfect for nature shots featuring birds, wild animals and other wildlife, and for capture of aircraft, trains, racing cars and more. Another major feature of our Sports line lenses is their wide range of customization functions: using the software provided, all sorts of settings can be tailored to the personal preferences of the photographer.
2. Dust-proof and splash-proof construction
For professional purposes, we have achieved excellent durability by incorporating dust-proof and splash-proof parts for joint parts, such as mount attachment, manual ring, zoom-ring, switches for customization and external switch panels. It prevents dust and dirt from entering the lens. Also, the usage of the zoom ring and focus ring is well positioned for shooting situations.
3. High image quality close to fixed focal length lens.
This lens incorporates 2 FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite, 1 SLD (Special Low Dispersion) glass element, and compensate for the color aberration at the utmost. The design also compensates for sagittal coma flare and minimizes the blurring of a point light source in peripheral areas. It offers very high image quality, close to fixed focal length lens.
4. Incorporation of focus limiter
Excellent usability is achieved by incorporating inner focusing and zooming that requires no change in the length of the lens for focus and zoom. It is possible to use with a rounded filter, such as a Circular Polarizer, as the front part of the lens is fixed. Due to the focus limiter offering adjustable range of auto focusing, this lens can provide fast focus setting. The USB dock enables users to change the range of the auto focusing at the discretion of users’ creativity.
5. Newly developed “USB DOCK” exclusively for new product lines
Based on these new lines, we have developed special software (SIGMA Optimization Pro) that can update the lens firmware and adjust parameters such as focus. In addition, the lenses from our Sports line have customizable AF speed, focus limiter and OS function. The “Custom Mode Switch” is the device for further customization on the dedicated lenses.
6. Ease of use
Many parts of this lens have been designed for comfortable usage. For example, the design of the zoom ring is concerned with a texture when you hold it, the position of printed letters and the 4 control switches with integration-considered shape of the screws. Included accessories such as the removable lens hood and the newly designed tripod collar with strap ensure added ease of use.
• Flare and ghosting conscious design
SIGMA’s Super Multi-Layer Coating reduces flare and ghosting. It provides sharp and high contrast images throughout the entire zoom range.
• Excellent in handheld photography for telephoto shooting
This lens incorporates the OS system which offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible, ensuring the excellent use in handheld photography for telephoto shooting. The OS system has two modes – OS mode 1 is suitable for general photography, and OS mode 2 is best for panning shots of subjects such as planes or racing cars. It is possible to adjust the OS using the optional USB DOCK.
* This lens cannot be used with film SLR cameras with the exception of the Nikon F6, Canon EOS-1v.
• Quiet and Fast AF
The HSM (Hyper Sonic Motor) ensures high speed and quiet AF as well as full-time manual focus override by rotation of the focus ring. With the enhanced AF algorithm, smoother AF is achieved. The full time manual, which offers further adjustment after focusing with AF mode, is possible. By using USB Dock, you can change and adjust the AF speed at your convenience.
• Incorporating Rounded Diaphragm
The 9 blade-rounded diaphragm creates an attractive blur to the out-of-focus areas of the image.
• APO Tele-Converter (Optional)
The addition of Sigma’s 1.4x EX DG APO or 2x EX DG APO TELE CONVERTER produces a 168-420mm F4 AF telephoto zoom lens or a 240-600mm F5.6 AF telephoto zoom lens respectively.
• Brass made bayonet mount
This lens incorporates a brass made bayonet mount which has both high accuracy and durability. A special treatment to reinforce its strength is applied to the surface giving it greater strength and making it highly resistant to long-term use.
• Evaluation with Sigma’s own MTF measuring system “A1”
We used to measure lens performance with an MTF measuring system using conventional sensors. However, we’ve now developed our own proprietary MTF (modulation transfer function) measuring system (A1) using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections. The SIGMA 17-70mm F2.8-4 DC MACRO OS HSM will all be checked using this “A1” before they are shipped.
• “Made in Japan”
All Sigma’s manufacturing – right down to the molds and parts – is carried out under an integrated production system, entirely in Japan. We are now one of the very few manufacturers whose products are solely “made in Japan”. We like to think our products are somehow imbued with the essence of our homeland, blessed as it is with clean air and water, and focused, hard-working people. We pride ourselves on the authentic quality of Sigma products, born of a marriage between highly attuned expertise and intelligent, advanced technology. Our sophisticated products have satisfied professionals and lovers of photography all over the world, because our manufacturing is based on genuine craftsmanship, underpinned by the passion and pride of our experts.

Sigma 35mm f/1.4 DG HSM
This Art lens provides photographers with a state-of-the-art alternative to the more conventional 50mm. This lens’ axial chromatic aberration is minimized, which renders a cool and smooth out-of-focus image. At low apertures, it can perform like a wide-angle lens; when opened up to F1.4, it will provide background bokeh and make the subject pop like a mid-range telephoto lens.
Sigma 17-70mm f/2.8-4 DC MACRO OS HSM
This new Contemporary lens is designed for cameras with an APS-c sensor and covers a range equivalent to 25.5 to 105mm on a 35mm camera. An upgrade to its predecessor, which was released in December 2009, this general purpose lens offers a new design and a more compact build.
Sigma 120-300mm f/2.8 DG OS HSM
With redesigned mechanics and performance, this Sports lens is an update from its predecessor released in February 2011. This high-performance lens eases difficult shooting conditions by offering a maximum focal length of 300mm and a wide-open aperture of F2.8. This lens, like the other Sports category lenses to come, is dust and moisture resistant, and allows users to adjust the focus speed and the focus limiter via a button on the lens.
