The Sigma 35mm f/1.4 Dg HSM A t lens is my all time favourite lens. I have always had the thought that a third party lens are cheap and they produce low quality images and not well constructed like the Big brands like Nikon/ Canon. But this lens proved me wrong, the 35mm focal length is great for general purpose use and having it on my Nikon D750 full frame body , the 35mm provides a modestly wide angle of view. The versatility of 35mm lens helped me to shoot portraits, landscapes, architecture and weddings.
Even though the sigma 35mm has a plastic body construction its feels very strong and sturdy, the plastic body is much better than the Sigma’s of the past. The aperture F/1.4 helps to take good handheld shots even in low light situations without any image stabilization. The shallow DOF and vignetting combination at f/1.4 can be used to successfully isolate a subject from its busy surroundings.
The Sigma 35mm f/1.4 DG HSM art lens is a amazing sharp lens – with very sharp centre even at wide open f/1.4.Vignetting at f/1.4 is strong which can be helpful while going for portraiture and the vignetting can be brought down by stopping down to f/2. The Images sharpness are pretty good in the centre but little softer at the edges .Off course the corners can be slowly improved until becoming very sharp at f/5.6 . And with this lens the chromatic aberration seems to be barely noticeable
The colour reproduction and bokeh is amazing in the Sigma 35 mm f/1.4.
A 35mm fr/1.4 can only be so light, and the sigma is tolerable. It is however heavier than both the Nikon and Canon counterparts. Like all of Sigma’s best lenses, uses HSM (Hyper Sonic Motor) AF, Auto focusing is internal and quiet. The only issue I find mainly in the Sigma 35mm f/1.4 is the autofocus speed of the lens is a bit slow than the Nikon and Canon. Sometimes it throws a complete miss. But that’s something I worry mostly during wedding and portraiture shoots, during the light painting ,landscapes or architectural shoot I mostly use manual Focus and the focus ring has a nice amount of resistance
The Sigma 35mm F/1.4 DG HSM art lens has Fantastic optics – as good as the Canon and Nikon with less distortion. And with amazing low price tag from Sigma, the 35mm f/1.4 is a good investment mainly for professionals or serious amateurs who demand excellent image quality and flawless operation .
