RF 100-300mm f/2.8L IS USM

[neuroanatomist]

Post your images from Canon's fifth 'great white' RF lens and first big white RF zoom, which is also the first big white lens to be designed for RF from the ground up (the first four were adapter±2xTC 'bolt-ons' of the EF 400/2.8 III and 6004/ III, at least from an optical standpoint).

This lens seems ideally-suited for indoor events and sports – that has been the majority of my use so far, and the lens does not disappoint. However, some have asked about performance with the 2x TC, as a possible substitute for a 600mm prime. The 600/4 + 1.4x was and remains my go-to for birding, but on an outing this past Saturday I took along the 100-300 + 2x planning to shoot at least one quick 'real world' comparison. This slow-moving great egret helpfully remained in the same location as I switched from 600/4 to 100-300 to 100-500. The first two are from a monopod, though I can handhold the 600/4 I often shoot on a monopod in warm weather. The 100-300/2.8 is definitely lighter than the 600/4, but neither is a light lens. That felt especially true the afternoon I took these, since I had spent that morning scuba diving.

Thanks for posting these. The 600 at 840mm clearly has the edge. The 100-500 has a bit of a halo around the Great Egret but looks slightly sharper than the 2x300mm.

It does. The "Stray Feather" shot posted in the bird portrait thread was from earlier in the day, same location with a great egret at about the same distance, that shot was a crop, here's the original for comparison to the above. That spot is near the entrance to the reserve, so I usually stop on the way in and again on the way out.

This is much sharper as there are 4x the number of pixels on the bird.

"Intercepted" – the body language of the receiver and the assistant coach tell the story...
