Canon RF 100-400mm f5.6-8 IS USM

Took this out for a weekend of birding and was honestly shocked at how easy it is to hold for hours. The image stabilizer let me nail sharp shots at 400mm handheld, even in fading light.

The image stabilizer on this zoom is genuinely impressive, I got sharp handheld shots at 400mm in dim evening light. It's surprisingly light too, so it barely weighs down my bag on longer walks.

Took it on a hike to shoot birds and the 100-400mm range covered everything from distant treetops to closer shots without swapping lenses. The image stabilizer really earns its keep at the long end, handheld shots at 400mm came out sharper than I expected.
