Strength: Sharp, with very good color contrast. Built solidly, a constant 2.8 with internal focus ( is not a dust pump). Good range for most applications. Not heavy so it can be a walk around lens. Weakness: For some not having USM is an issue. It is a discontinued model so parts and service could be an issue.

This 20-35mm has fantastic ergonomics. Nothing moves externally as it's zoomed or focused, and all the controls are exactly where they should be and feel great. This 20-35mm has instant manual focus override Coming to you from Gordon Laing, this excellent video review takes a look at the Canon RF 15-35mm f/2.8L IS USM lens.The 15-35mm f/2.8L comes with two Ultra-Low Dispersion elements for reduced The RF 15-35 has dramatically less barrel distortion and lateral CA. The Canon RF 16mm F2.8 STM Lens vs. Canon RF 15-35mm F2.8 L IS USM Lens comparison shows the prime lens to be dramatically smaller and lighter than the zoom. Correspondingly, the RF 16 uses smaller filters (43mm vs. 82mm) and has a higher maximum magnification (0.26x vs. 0.21x).
