The definition of versatility, the Canon EF-mount Sigma 24-105mm f/4 Art Lens for Canon EFfrom Sigma 24-105mm f/4 Art Lens for Canon EFis an Art-series zoom covering a useful wide-angle to short-telephoto range. Featuring a constant f/4 maximum aperture, this lens strikes an ideal balance between a portable form factor along with a bright enough design for working in available lighting conditions. Complementing this design, an Optical Stabilizer helps to minimize the appearance of camera shake throughout the zoom range for sharper handheld shooting. A Hyper Sonic Motor also contributes to intuitive handling and provides especially fast and quiet autofocus performance along with full-time manual focus override.

Complementing the physical design, this lens is also distinguished by its advanced optical layout, which include a series of low dispersion elements and three aspherical elements. These specialized elements reduce chromatic and spherical aberrations throughout the zoom range in order to realize a high degree of sharpness and clarity. Additionally, a Super Multi-Layer Coating has also been applied to individual elements to suppress lens flare and ghosting for improved contrast and color rendering in strong lighting conditions.

As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.

Standard zoom is designed for full-frame Canon EF-mount cameras, however can also be used with APS-C models where it provides a 38.4-168mm equivalent focal length range.

Constant f/4 maximum aperture maintains a portable form factor and also offers consistent performance throughout the zoom range.

Two F Low Dispersion (FLD) elements and two Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy.

Three aspherical elements control spherical aberrations and distortion for increased sharpness and accurate rendering.

A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.

Integrated HSM (Hyper Sonic Motor), along with an internal focusing system, realizes quick and quiet autofocus, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.

Optical Stabilizer system minimizes the appearance of camera shake to benefit making sharper imagery when shooting handheld.

Rounded nine-blade diaphragm is constructed from durable, fluorine-coated polycarbonate and also features a carbon feather film for smooth performance when working with fast continuous shooting rates.

Constructed using a Thermally Stable Composite (TSC) material for greater precision and use in wide temperature variations. Additionally, a brass bayonet affords improved mounting accuracy and rigidity.

This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.

Q: 1. hi is this lens compatible with sony A7 ?

A: No, the Sigma 24-105mm F/4 DG OS HSM Lens for Sony DSLR Cameras is not directly compatible with the Sony Alpha a7 Mirrorless Digital Camera. The Sigma 24-105mm F/4 DG OS HSM Lens for Sony is designed for use with the larger Sony DSLR cameras that use the Sony Alpha or Minolta MAXXUM lens mount, not the smaller Sony mirrorless NEX E-mount. As such, you would need an adapter, such as the Sony A-Mount to E-Mount Lens Adapter with Translucent Mirror Technology (Black), B&H # SOLAEA4, to use the lens on the Sony a7. If you want a lens with a similar range that is designed for the NEX E-mount, then I would recommend either the Sony Vario-Tessar T* FE 24-70mm f/4 ZA OSS Lens, B&H # SO24704, or the Sony FE 28-70mm f/3.5-5.6 OSS Lens, B&H # SO28703556.

Q: 2. Can someone explain more about the dock mentioned in the description, how much, what it's used for, etc? Thanks!

A: I have the dock and found it VERY useful for re-setting focus for Sigma 35mm 1.4 Art and 50mm 1.4 Art both are stellar lenses. Rather than just use the body and set focus closer or the like, this allows you to set the focus near/far at about FOUR different focus ranges. Example: 14 - 18 then 18 - 24 then 24- 38 then 38 - infinity -- those are just *guesses* at the ranges. I don't remember. But extensive testing showed that the lenses needed maybe +4 at the near range, +2 at mid range and -1 at infinity. You cannot do that with the camera body. And with a zoom, I'd imagine it to be even more important/useful.

Q: 3. Would you consider this a better lens than the sony G series 24-105? Also if they don't have this E-mount do they have an adapter?

A: The Sony 24-105mm G lens is higher resolution than the Sigma Art lens. Their is a Sigma MC-11 adapter EF to E mount, that sometimes gives the user autofocus.

Q: 4. Does this lens use inner focus of no?

A: This lens does have internal focus, however as you go through the zoom range, the lens will extend out.

Q: 5. Does this lens feature hard stops for focusing?

A: There are no hard stops. In fact distance indicator is not accurate - it changes depending upon zoom. Also, if you are focused on something and change the zoom, the focus will also change. For example, in dim light focused near infinity will be out of focus if you change the zoom. Very annoying. Nikon lenses do not do this.

Q: 6. Hi, What is SLD stands for?ThanksPeter

A: SLD stands for Special Low Dispersion glass. It is one of several optical blade types they use in their lens designs. The purpose of this and any type of Low Dispersion glass is to help light maintain a straight path to the sensor (and not disperse another direction) which helps maintain sharpness, contrast, and color accuracy.

Q: 7. Will this lens work on my Nikon f80 or F100 film cameras with full functionality?

A: On the F100 I am almost positive it will. I am not familiar with the F80. It's an amazing lens.

Q: 8. is this lens good for portraits?

A: yes. it's a great all around lens. super sharp. you could always wait for a 2.8 24-70 from their Art line, but the 105 is a longer reach.

Q: 9. Has any one used this lens with the MC-11 on the Sony A7M2? If so would love to hear you thoughts about the combo.

A: This lens will be fully compatible in all lens functions when used with the MC-11 on the A7R II.

Q: 10. I have an a77, would this lens well with it ?

A: It is an excellent lens, the best lens you can have for that amount of money.
