Sigma Art line delivers high-level artistic quality
Sigma is organizing all its interchangeable lenses into three product lines; Contemporary, Art and Sports. Designed with a focus on sophisticated optical performance and abundant expressive power, our Art line delivers high-level artistic expression. Developed with the maximum emphasis on artistic touch, our Art line lenses are designed to meet the expectations of users who value a creative, dramatic outcome above compactness and multifunction. Along with landscapes, portraits, still-life, close-up and casual snaps, they're perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much expressive scope when capturing architecture, starry skies, underwater shots and many other scenes. The SIGMA 35mm F1.4 DG HSM is the first lens from the Art line.
Compensate for color aberration to ensure unsurpassed expressive performance
Aberration is an important factor for the lens performance. To actualize a high-performance lens, one of the essential elements is aberration correction. When it comes to aberration, there are chromatic aberration of magnification and axial chromatic aberration. It is possible to correct the chromatic aberration of magnification in photo-editing software whereas axial chromatic aberration cannot be corrected afterwards. This lens incorporates FLD ("F" Low Dispersion) glass elements, which have performance equal to fluorite, and SLD (Special Low Dispersion) glass elements, and by optimizing the power alignment of the lens, both types of aberration have been corrected. The lens achieves ultra-high image quality through the entire focusing range. Also, by appropriate alignment of aspheric lenses, astigmatism and field curvature are corrected. The result is superior optimum resolution even in peripheral areas.
Large maximum aperture of F1.4
In 2005, Sigma released a lens that has aperture value F1.4 designed for digital SLRs, "SIGMA 30mm F1.4 EX DC HSM". Since then, we have produced high-performance lenses by incorporating the latest optical technique, such as the standard lens designed for a full size image sensor, the SIGMA 50mm F1.4 EX DG HSM and the medium telephoto lens with large aperture, SIGMA 85mm F1.4 EX DG HSM. This lens, SIGMA 35mm F1.4 DG HSM, is our fourth lens that achieves extraordinary expressive power at the aperture value at F1.4. For wide angle photography, it ensures excellent brightness with the large F1.4 aperture and a beautiful bokeh effect.
Attractive blur effect
Correction of coma aberration enabled less blur on a point light source in peripheral areas, and the function is best used for astrophotography and illuminations. It is also possible to create an attractive blur to the out of focus areas. The aspheric lens elements used as the first lens have secured peripheral brightness while correcting distortion. The rounded diaphragm creates an attractive blur to the out-of-focus areas of the image.
Floating inner focusing system
This system compensates for astigmatic aberration and spherical aberration and provides extremely high optical performance for close-up photos.
Flare and ghosting conscious design
In order to achieve high rendering on this flagship lens, flare and ghosting were thoroughly measured from an early stage to establish an optical design which is resistant to strong incident light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions.
Hyper Sonic Motor
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.
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
Ease of use
The new product lines incorporate rubber for the attachment part of the provided lens hood. For better usability, the design of the lens cap and AF / MF changeover switch have been improved. In order to ensure high accuracy of the product, all metallic parts and the new compound material, TSC (Thermally Stable Composite), which has high affinity to metal parts, are housed internally.
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.
Evaluation with Sigma's own MTF measuring system "A1"
We used to measure lens performance with 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 35mm F1.4 DG HSM will all be checked using this "A1" before they are shipped.
"Made" in Japan
All Sigma's manufacturing right down to 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 genuin e craftsmanship, underpinned by the passion and pride of our experts.
I decided to buy this lens because of its extremely high reputation. But actually it doesn't work for every case. When I first used this lens I found it had focus shifting problem. I couldn't focus on what I wanted to put. Then I contacted the custom service and I was told to test using LCD screen focus. Surprisingly, it worked! But, wait, how many times do you guys use LCD to photograph? Any modern DSLR doesn't have enough confidence in its battery capacity. So Sigma blames this problem to inaccurate focus system of Nikon. But the question is why Nikon its own lenses don't have any such problem? Only using LCD focus, are you kidding me? I Googled solutions to this problem. And I found I had to spend another $50+ on Sigma USB Mount to adjust the lens in its Rom. More over, I had to print out a focus scale in order to measure how far the lens deviates its real focus. If you don't know how to make the scale, you need to spend more than 100 bucks to buy a standard focus adjustment scale. OK, I followed all instructions to find the deviations and wrote them into the lens through the USB mount. But it had pasted almost half month before I could use this lens normally. So if you can afford such inconvenience, please do it.
Still new but hasn't left my camera. Loving it for use in tight spaces.
Talk about sharp, this lens blows me away. Get it.
GREAT LENS! PEOPLE SAY ITS TO HEAVY, WELL GLASS IS HEAVY BUT THIS LENS IS NOT TO HEAVY! GOT IT FROM ADORAMA AS A USED "DEMO". I WOULD DO IT AGAIN! YOU CAN TRUST ADORAMA!
After reading countless reviews about this lens for months, I finally decided to buy it. I'm SO glad that I did. It performs beautifully on my Nikon D800! It's tack sharp, even wide open. It's just the right amount of contrasty, and I've been more than thrilled with the images I'm getting from it!
All the hype about this lens is true. I absolutely love the clarity and depth that I get in my photos with it. Can't beat the price or the quality. Best purchase I've made!
I bought it to do wide field night astrophotography and so far have not had great success. There is a good chance it is not a lens problem but as of now I cannot tell. I am seeing either or both vignetting and sky gradients. The appeal for me was that it was really fast and that is a huge benefit to astro imagers. But at f/1.4 to f/2.8, the results are disappointing. Other imagers have had excellent results.
After reading reviews and seeing the examples of photos taken with this lens I had to have one...Best purchase ever. I love the clarity, color depth, and bokeh from this lens. Absolutely gorgeous. I have owned several Sigma lens over the years and this one has the best build quality I have seen. Sigma hit this out of the park! My brother was so impressed he is going to buy one for his Canon.
I've been playing with this lens daily and I'm still amazed how good it is. Wide open I got a little touch of purple fringe on light against dark on a picture of a spotting scope. This happened once and the fix was to shoot at 1.8 instead of 1.4 for that picture. Nothing is perfect but this lens is close. The build quality is superb and the focus is fast and silent. The low light indoor pictures I've been taking are turning out better than I thought possible. This lens will be my main walk around from now on. I also own a 50-500 Sigma that does an outstanding job.
I also own a Nikon 24-70 which is def one of my favorite lenses but after reading all the hype I just had to have one of these. To me, it's just one of those exceptional lenses that only comes along once in a great while. The color rendition, clarity, and bokeh is just all so beautiful. The out-of-focus areas have a creaminess that is hard to explain. Regarding the feel of this lens, you can tell it is well made and that you are holding a fine piece of glass. Sometimes it does have a little trouble focusing in low light situations, but I can live with that in exchange for what I get in return.
