The Tamron lens’s constant F2.8 aperture allows for excellent low-light performance, which is vital for capturing sharp images in various lighting conditions.
Focal Length Versatility
Focal length versatility is another significant differentiator between these two lenses. The Canon RF35mm offers a fixed focal length of 35mm, making it an excellent choice for portraits and landscapes with a unique perspective. Conversely, the Tamron 17-70mm covers a focal length range of 17-70mm, equivalent to 25.5-105mm in full-frame terms, providing a wide zoom ratio of 4.1x.
