The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Tokina atx-m 33mm F1.4 E and the Sigma 35mm F2 DG DN for their suitability to various photography scenarios:
Size and Weight Comparison
The size of a lens is a crucial factor to consider when comparing two lenses. Tokina atx-m 33mm F1.4 E is the longer of the two lenses at 72mm. The Sigma 35mm F2 DG DN with a length of 65mm, is 7mm shorter. On the other hand, the Sigma 35mm F2 DG DN has a larger diameter of 70mm compared to the Tokina atx-m 33mm F1.4 E's 65mm diameter.
The weight of a lens is equally significant as its external dimensions, particularly if you intend to handhold your camera and lens combination for extended periods. Tokina atx-m 33mm F1.4 E weighs 285g, which means it is 40g (12%) lighter than the Sigma 35mm F2 DG DN which has a weight of 325g.
Filter Threads
The Tokina atx-m 33mm F1.4 E has a filter size of 52mm whereas the Sigma 35mm F2 DG DN has a 58mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 52mm filters that we recommend you to consider for the Tokina atx-m 33mm F1.4 E:
And these are the 58mm filters that we recommend for the Sigma 35mm F2 DG DN:
Lens Mounts
Both the Tokina atx-m 33mm F1.4 E and the Sigma 35mm F2 DG DN has the same Sony E lens mount. Some of the latest released cameras that are compatible with the Sony E lenses are Sony A6700, Sony FX30 and Sony ZV-E10.
Sigma 35mm F2 DG DN is also available in Leica L mount.
Focal Range
Tokina atx-m 33mm F1.4 E is a prime lens with fixed focal lenght of 33mm which has an effective (full-frame 35mm equivalent) focal range of
49.5mm when used on a APS-C / DX format camera.
On the other hand, the Sigma 35mm F2 DG DN is a prime lens with fixed focal lenght of 35mm. When it is mounted on an APS-C sensor camera with 1.5x crop, it provides a 35mm (FF) equivalent of 52.5mm.
