The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Venus 24mm F14 2x Macro Probe and the Sigma 30mm F1.4 DC HSM 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. Venus 24mm F14 2x Macro Probe is the longer of the two lenses at 408mm. The Sigma 30mm F1.4 DC HSM with a length of 63mm, is 345mm shorter. On the other hand, the Sigma 30mm F1.4 DC HSM has a larger diameter of 74mm compared to the Venus 24mm F14 2x Macro Probe's 38mm 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. Sigma 30mm F1.4 DC HSM weighs 435g, 8% (39g) lighter than the Venus 24mm F14 2x Macro Probe's weight of 474g.
Lens Mounts
Both the Venus 24mm F14 2x Macro Probe and the Sigma 30mm F1.4 DC HSM has the same Canon EF lens mount. Some of the latest released cameras that are compatible with the Canon EF lenses are Canon 1D X III, Canon 6D MII and Canon 5D MIV.
Venus 24mm F14 2x Macro Probe is also available in Nikon F (FX) and Sony E mounts.
Sigma 30mm F1.4 DC HSM is also available in Nikon F (DX) and Sigma SA mounts.
Focal Range
Venus 24mm F14 2x Macro Probe is a prime lens with fixed focal lenght of 24mm. When it is mounted on an APS-C sensor camera with 1.6x crop, it provides a 35mm (FF) equivalent of
38.4mm.
On the other hand, the Sigma 30mm F1.4 DC HSM is a prime lens with fixed focal lenght of 30mm which has an effective (full-frame 35mm equivalent) focal range of 48mm when used on a APS-C / DX format camera.
