Sigma 18-50mm F2.8 vs Tamron 17-70mm F2.8 for Fuji X-Mount | Which is Better?

Introduction

Hi, I’m Dustin Abbott, and after months of research, I’m here to compare the Sigma 18-50mm F2.8 and the Tamron 17-70mm F2.8 for Fuji X-Mount cameras. Both lenses are third-party options that offer fast apertures and versatility in a standard zoom range. Today, we’ll dive into the strengths and weaknesses of each lens to help you determine which one might be better suited for your needs.

Common Strengths

Both the Sigma 18-50mm F2.8 and the Tamron 17-70mm F2.8 share a maximum aperture of f2.8 throughout their zoom ranges. This consistency in aperture can be useful for low light shooting and creating shallow depth of field effects. Additionally, both lenses are more affordable than Fuji’s own 16-55mm F2.8 option, making them attractive alternatives for budget-conscious photographers.

Common Weaknesses

One common weakness of both lenses is the lack of an aperture ring or on-lens controls. This may be a drawback for photographers who prefer to have tactile control over their aperture settings. Additionally, both lenses exhibit noticeable warping and focus adjustments during video zooming, which can be distracting for videographers.

Reasons to Choose the Sigma 18-50mm F2.8

The Sigma lens stands out for its compact size and lightweight design. At only 61.6mm in diameter and 76.8mm in length, the Sigma is significantly smaller than the Tamron, making it a more portable option for travel or everyday shooting. Additionally, the Sigma is priced at $549, making it more affordable than the Tamron at $799. In terms of optical performance, the Sigma shows better flare resistance, higher magnification capabilities, and slightly sharper center and mid-frame performance compared to the Tamron.

Optical Performance

During my testing, I found that the Sigma exhibited slightly better flare resistance and sharper center and mid-frame performance across the zoom range. Additionally, the Sigma showed better telephoto performance with lower vignetting. In terms of autofocus, the Sigma focused faster and quieter, with less visible stepping during focus pulls in videos.

Conclusion

Ultimately, the choice between the Sigma 18-50mm F2.8 and Tamron 17-70mm F2.8 for Fuji X-Mount cameras will depend on your specific needs and preferences. If portability, affordability, and optical performance are key factors for you, the Sigma may be the better choice. However, if you prioritize a wider zoom range and don’t mind a larger and heavier lens, the Tamron could also be a suitable option. Both lenses offer distinct advantages and it’s important to consider how each aligns with your shooting style and requirements.

Thank you for reading and I hope this comparison has helped you in making an informed decision about which lens is better suited for your photography needs.
