The 5.8-pound weight may sound heavy, especially for enthusiasts used to carrying a lens like the 3-pound RF 100-500mm, but it's not too much more than the 5.3-pound EF 300mm F2.8 prime for Canon
FALLOFF (Darkened Corners) back to Performance or back to Introduction. The 17-55mm is very good. There is some falloff at f/2.8 which goes away at f/4. These tests below are extremely devious and show even the slightest falloff. The level of falloff seen at f/4 below will be invisible in real photos.
The Canon RF 400mm f2.8 feels like a cannon (lowercase C, three Ns). It’s a 14.4-inch lens that weighs almost 6.5 pounds. Handholding this lens was a workout; I was exhausted at the end of my hike.
Any differences are probably copy variation as these older lenses have more significant variation. It all depends on if you'd rather have 85mm or 100mm. 85mm is a little bit more handholdable in low light with the shorter length and f1.8. 100mm gives a little more compression.
