With a no-holds-barred approach to design, the Leica L-mount Sigma 105mm f/1.4 DG HSM Art Lens Leica Lfrom Sigma 105mm f/1.4 DG HSM Art Lens Leica Lis a short-telephoto, portrait-length prime distinguished by its bright maximum aperture and advanced optical layout. The fast f/1.4 design greatly benefits working in low-light conditions and also affords extensive control over depth of field for isolating subjects and working with selective focus. As part of the Art line of lenses, this lens is also designed for high-resolution rendering, and utilizes FLD and SLD glass to control chromatic aberrations and color fringing for notable clarity. A Super Multi-Layer Coating also enhances image quality by suppressing lens flare and ghosting for improved contrast and color fidelity in strong lighting conditions. Additionally, a rounded nine-blade diaphragm contributes to a pleasing bokeh quality.

Complementing the imaging capabilities, the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with full-time manual focus override. The physical design utilizes Thermally Stable Composite material for durability in a wide range of environments, and a brass bayonet mount also offers rigidity and mounting precision. For working atop a tripod, a removable tripod collar is also included and features an Arca-type compatible foot for wide mounting compatibility.

Impressively bright f/1.4 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.

Three F Low Dispersion (FLD) and two Special Low Dispersion (SLD) elements are featured in the optical design, and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy.

One aspherical element is used to help limit distortion and spherical aberrations and also contributes to greater overall sharpness and accurate rendering.

Large 105mm-diameter front contributes to improved peripheral illumination in order to reduce vignetting.

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.

Nine-blade rounded diaphragm contributes to a smooth and pleasing bokeh quality.

The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, 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.

The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations.

The bayonet mount is constructed from brass for ensured accuracy and durability. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.

Protective coating has been applied to the front element and is both water and oil-repellent to aid in cleaning.

Included rotating tripod collar features an Arca-type compatible foot for seamless use atop a tripod or monopod. This collar can also be removed from the lens, and a protective cover takes its place, for more comfortable handheld use.

Lens hood is constructed from a carbon fiber reinforced plastic to remain lightweight yet exceptionally durable.

Q: 8. I have the 24-70ii lens already for my 6D but I would like to add a prime lens to my kit. I am contemplating the sigma 35 art and the 50 art. I like the idea of adding one of these two because I feel like they can provide a more unique style that my 24-70 can't (bokeh and low light). I also already have the canon 50 f1.8 but although its a good lens for the price, it's not my favorite lens. I like the idea of the 50 for portraits of my daughter but I feel like the 35 is generally more my style because of it's versatility but does that make sense if I already have a 24-70 and I want a good portrait lens? I feel like most people would agree to get the 35 since I already have a 50 but I'd be fine replacing that lens and never using it again. Any advice/input is welcomed. Thank you!

A: Go with the 50mm art lens. Replace your canon. You will love the 50mm art lens and I think your 24-70 can pick up the 35mm look that you want. I have told 2 other photogs about this lens and they agree and have sold their canon 50mms.

Q: 9. I am really torn between getting this great lens or the Nikon 50 f/1.4G. For those of you who really like the Sigma 50, what can you tell me about it specifically that will make me want to buy it over the Nikon 50 1.4G?

A: There are pros and cons. The Nikon 50 is not as sharp and slow focusing, but it can AF in low light. The Sigma is sharper, focus fast but can't AF as well in low light. Maybe 50% hit and miss. Doesn't work will with Nikon flash system too. Also may have issues in movie mode. Maybe the bokeh is better on the Nikon too. I'll get the Sigma for landscape where you manual focus and need sharp images, but I would not use it on important assignments where you have low light situations. The Nikon maybe a better all round lens but i find it out dated.

Q: 10. Can i use all the funtions of the lens on a6000?

A: Yes, it is fully compatible with the Sony a6000.
