Sigma 30mm 1.4 canon review6/30/2023 The focus ring is also an improvement, and a step above the Sony. Compared to older Sigma DN lenses, the 30mm F1.4 doesn't let its focus elements rattle about when unmounted, which is a very welcome change. They both use a machined metal chassis with plastic internals. The difference between them doesn't suddenly open one up to a type of photography that couldn't be achieved with the other.īuild quality between the Sigma and the Sony is fairly similar. In stills terms, though, there's little real-world difference between the Sigma's 45mm equivalent view and the 52.5mm equivalent of the Sony. That alone gives it a better chance at being the preferred lens for video, although when shooting 4K the slightly wider FOV of the Sigma might fare better on any body that gives an additional crop. First, while the Sony is 2/3 of a stop slower than the Sigma, it does include optical image stabilization. In terms of just spec we see a couple of major differences. Let's look at how the two stack up on paper:ġ aspherical and 1 double-sided aspherical Within the E-mount system this lens has one natural competitor: the Sony 35mm F1.8 OSS. The relatively low price, especially for an E-mount lens, means it's also accessible to beginners and enthusiasts alike, making it sound like an ideal prime lens that may never leave the front of the camera once it's mounted. While it won't replace a dedicated macro lens with its magnification ratio of 1:7, it still is able to focus down to a working distance of 30cm (less than a foot). The bright aperture will satisfy low light shooters and bokeh fanatics, and the near 50mm field of view puts it right inside the versatile 'normal' lens range. With F1.4 and a 45mm equivalent field of view, this lens on paper appears to be a good choice for a 'walkaround' normal prime lens. It's currently the only APS-C F1.4 autofocus lens currently available for the Sony E-mount and has an MSRP of $339.00. The Sigma 30mm F1.4 DN DC Contemporary was announced in February 2016, and sits atop Sigma's line of DN mirrorless lenses, with a two-stop advantage over their previous 30mm F2.8 offering.
