Excerpt: Handling and features This lens is the first of Sigma's new 'Art' line of lenses that promise excellent optical quality and increased creative options thanks to a fast f/1.4 maximum aperture. Being one of Sigma's top of the range lenses, it sports a hypersonic focusing motor, brass lens mount and build quality normally reserved for their EX line of lenses.
Summary: The Sigma 35/1.4 DG HSM is a very exciting lens. You can produce shots with image quality you might think were impossible at a wide open aperture of f1.4. Plus the build-quality and the new design support Sigma's claim to have developed and manufactured a lens to professional standards. I was quite shocked to see this lens surpass the optical performance of the venerable Nikon AF-S 35mm f/1.4G with respect to sharpness.
Pros: Outstanding performance in the corners of a high-resolution full-frame sensor even wide open., Good build quality., Quiet and fast AF operation., Relatively low price compared to the big names.
Cons: Performance at the borders/corners of the DX/APS-C image circle could be better., No weather sealing.
Summary: The Sigma 35mm F1.4 DG HSM is a truly excellent lens, that performs as well in the field as its superb lab test results suggest. With fast silent focusing and solid build, its lower price makes it a compelling alternative to the camera manufacturers' equivalents if you don't need weather-sealing.
Pros: Superb optics that beat anything else in its class, Impressive flare resistance, Fast, silent, and accurate autofocus, Excellent build quality, Very competitive price
Cons: Slightly fussy rendition of out-of-focus backgrounds under some conditions, No weather sealing
Excerpt: The Sigma 35mm f/1.4 DG HSM Art Lens is the first result coming out of Sigma's recently announced lens lineup restructuring. This lens represents a completely new look and feel for Sigma - a very positive upgrade from a physical perspective and a big hit from an image quality perspective.
Summary: The 35mm focal length has provided a classic angle of view for general photography ever since the days of film, and it's just as relevant for 'full frame' cameras in the digital era. Whether it's equally useful for cameras with APS-C sensors depends on how much you need lens speed. This is an excellent 'walkabout' lens and great for street photography. It's rugged enough to take bushwalking, although on the heavy side and not water-resistant.
Sigma AF 35mm f/1.4 HSM DG | A ("Art") - Review / Test Report
23 April 2013
Conclusion: In the recent years, Sigma has managed to reinvent itself - which is a rare thing for big companies. They started as a company emphasizing price over quality but we have to admit that we are immensely impressed by the recent shift. They are pressing all the right buttons lately and the Sigma AF 35mm f/1.4 HSM DG | A is a shining example of this turnaround. From the fast primes that Sigma has introduced so far, this is the best one, yet.
Sigma AF 35mm f/1.4 HSM DG | A ("Art") - APS-C Format Review / Test Report
13 April 2013
Conclusion: The Sigma AF 35mm f/1.4 HSM DG | A impressed us during our full-format tests but it can't completely fulfill our very high expectations in the APS-C scope. Now, the center quality remains nothing short of breathtaking especially considering its ultra large aperture. However, normally the "APS-C border" figures tend to be better compared to the "full-format borders" simply because they are physically closer to the better center. However, this is not the case here.
Sigma AF 35mm f/1.4 DG HSM | A ("Art") (Nikon DX) - Review / Test Report
7 April 2013
Conclusion: The Sigma 35mm f/1.4 shows decent performance on the D7000. The center resolution is very high, while the borders and especially the corners are a bit soft wide open. The lens needs to be stopped down considerably to delivery very good resolution across the frame.
Sigma AF 35mm f/1.4 DG HSM | A ("Art") (Nikon FX) - Review / Test Report
26 February 2013
Conclusion: From the fast primes that Sigma has introduced so far, this is probably the best one, yet. The resolution is impressive, CAs and distortion are well under control. Vignetting is quite pronounced at large apertures, but that's not really a surprising result for such a fast lens. The bokeh quality is not as dreamy as on fast portrait lenses, but quite smooth for a wide angle lens.
