Spec Comparison of Both Lenses
Physical Dimensions
You get slightly different physical measurements for each mount version. The SSE Sigma 18-50mm f/2.8 Sony E-Mount measures 2.57 inches in width and height, with a length of 2.93 inches. The SSE Sigma 18-50mm f/2.8 Fujifilm Bundle is marginally more compact, measuring 2.56 inches in width and height, and 2.9 inches in length. The difference is minimal, but the Fujifilm version is a fraction smaller in every dimension. This tiny variance might matter if you have a very tight camera bag, but for general portability, both are highly similar in size and weight profile.
Sensor Format
The Sony E-Mount lens explicitly lists APS-C as its sensor format in its attributes and key specifications. This confirms it is designed for Sony APS-C mirrorless cameras. The Fujifilm X Mount lens does not explicitly state the sensor format in the provided data, though the Fujifilm X mount is inherently for APS-C and full-frame cameras. Since the Fujifilm data lacks this specific text confirmation, the Sony listing provides clearer specification evidence for APS-C compatibility. If you need explicit confirmation of the sensor format from the product data, the Sony option offers that detail directly.
Included Accessories
Both lenses are sold as bundles that include the same set of accessories. Each package contains a 3-piece filter kit, a 6-piece gradual filter set, a lens pen, a dust blower, and a starter cleaning kit. You also receive manufacturer accessories with each purchase. The accessory list is identical for both the Sony E-Mount and Fujifilm X Mount versions. There is no difference in what you get in the box regarding protection and cleaning tools. This tie means you do not need to choose based on included extras, as both provide equal value in this category.
Mount Compatibility
Compatibility is the primary difference between these two lenses. The SSE Sigma 18-50mm f/2.8 Sony E-Mount is designed specifically for Sony E-Mount APS-C mirrorless cameras. The SSE Sigma 18-50mm f/2.8 Fujifilm Bundle is designed for Fujifilm X Mount mirrorless cameras. You cannot use the Sony mount lens on a Fujifilm camera without an adapter, and vice versa. This is not a quality difference, but a strict compatibility requirement. You must select the version that matches your camera body's mount. Your camera system dictates which lens you can use.
Aperture Performance
Both lenses feature a constant f/2.8 maximum aperture across their entire 18–50mm zoom range. This specification is identical for both the Sony and Fujifilm versions. A constant f/2.8 aperture allows for better low-light performance and consistent exposure settings regardless of the focal length you are using. It also enables beautiful background separation or bokeh for portraits. Since the aperture specs are exactly the same, neither lens has an advantage in light gathering capability or depth of field control. You get the same optical performance regarding aperture in both options.
