The Canon TS-E 45mm f/2.8 Tilt-Shift Lens has minor light fall-off wide open (f/2.8) and minor CA (Chromatic Aberration). Flare-resistance is moderate - the Canon EF 50mm f/1.4 USM Lens proved better for flare resistance. Full shift decreases sharpness, increases CA and introduces vignetting (on a full frame body).
The EF 16-35mm f/2.8L II USM incorporates three aspherical elements to ensure corner-to-corner sharpness and clarity throughout the focal range. Two UD (Ultra Low Dispersion) elements virtually eliminate chromatic aberrations.
Canon SLR owners in search of a low-cost macro lens are in for a treat. The EF-S 35mm f/2.8 Macro IS STM ($349.99), compatible with APS-C sensor cameras, focuses close enough to capture images at
APS-C format sensor cameras will see about 1.5 stops of shading in f/2.8 corners. With shading falling under 1 stop at f/4, stopped-down images captured with these cameras will have no noticeable shading issues in most scenarios. The Samyang 14mm f/2.8 Lens takes control of CA (Chromatic Aberration).

The biggest benefit of the older EF 135mm f/2L USM lens is its compatibility with Canon extenders. Combining the EF lens with a 2x extender makes it a great 270mm f/4 lens. The RF 135mm f/1.8 IS
The EF 20mm f/2.8 lens weighs in at a mere 14.29oz (or .89lbs) which means it is very light weight when mounted on your camera. This is significant when you compare it to a lens like the 16-35mm f

The Sigma 14-24mm f/2.8 DG HSM Art Lens has a 10.2" (260mm) minimum focus distance that, at 24mm, delivers a 0.19x maximum magnification. The 0.19x spec is a very strong one for lenses including a wider-than-16mm focal length, though the spec is only mediocre among lenses overall.
