A fast aperture, standard zoom can often be the most important lens in any person’s kit. These are the types of lenses that cover 80-90% of most photographer’s needs, but do so in a more compelling way than most kit lenses. The constant maximum aperture of F2.8 helps in low light and creates a more shallow depth of field, and the focal length covers from moderately wide to short telephoto. The two main third party competitors on the Fuji X-mount platform come from Sigma (the Sigma 18-50mm F2.8 DN) and Tamron (the Tamron 17-70mm F2.8 VC RXD). I’ve spent extensive time with both lenses (I currently own both of them) and have been comparing them for months. My findings are summarized in this video review.

Thanks to TTArtisan for sending me a review copy of this lens.   As always, this is a completely independent review.  All opinions and conclusions are my own. I’m doing this review on a 40MP Fujifilm X-H2 camera.

__________________________________________________________________________________________________

Both of these lenses are critical and commercial successes. The Sigma has a 5 out of 5 star rating at B&H Photo with 112 reviews, while the Tamron has a 4.5 star rating with 54 reviews. Both companies took radically different approaches to this formula, however, as the Sigma is the smallest, lightest, and cheapest option (including the Fuji 18-55m F2.8-4 OIS and 16-55mm F2.8 LM WR options) while the Tamron is the largest lens in class but also has the largest zoom ratio and has both a constant F2.8 aperture along with an optical stabilizer.
