Excuse Us! We're Busy Here!
As you may have seen from my recent photos, we just had 4 fledglings leave the nest. On a darker note, a raptor of some kind appeared to have killed a robin in the backyard, and we're hoping it wasn't mom. Hard to tell since we have quite a few robins around. I am also surprised you have 2 adults in this shot, we only saw one the entire time here. Nature sure is tough.

I think this lens (EF 600mm f/4 III) is very good for bird-images. I'll try the 1,4 extender as well. The images turn out rather well I think. (Like they did on my previous RF 100-500 as well, but I like the extra stop).

We have a couple of raptors (Red-tailed Hawks?) in our neighborhood and these robins are skittish as if I even get close to the nest they will dive bomb me. I was startled me at first, but I got use to it and I try to put them at ease by backing away from the nest as possible. My neighbor has a bird feeder on the window and the birds will gather around the nest (on the roof and cable wire) when I'm around. Birds are smarter that people think they are and nature acts funny at time. I think the birds are getting tired of the hawks being around and are grouping up in numbers for protection.

I agree, it seems like it does a great job for birds. On this shot, does the body detect the bird, or do you fine-focus to get the bird through the branches?

The AF finds the bird instantly. Then eye following AF takes over, so I don't have to do much at all. Just composing and keep the bird in frame, so to speak.
Real game changer with that automation.

In reality the 600mm f/4 can be used even with the 2x TC and still outperform the RF 100-500mm without a TC. The reason for this is that the RF 100-500mm has an aperture off f/4.5 starting at 100mm, and then decreases (closes) to f/7.1 as it nears 500mm. It you use a 1.4x TC with the RF at 100mm may be OK, but as it nears 500mm, it is already a f/8 or worst lens. The 600 f/4 may lose around 2 f-stops with the 2x TC, but still is a f/6 lens all the way to 1,200mm., which should not be a problem during the day since there is plenty of daylight.

That said, the EF 600mm f/4 with a 1.4x TC is not bad at all, since you are losing around 1 f-stop at a constant 800mm. Yes, the EF 600mm lens costs a great deal of money because it is a real pro lens if compared to the RF 100-500mm.

Oh, thank You for that information.
If I recall correctly the RF100-500 can't use a TC under 300mm. You "only" get 300-500 with a TC on that particular lens. And, yes, I will buy the 1,4 III from Canon and play around with a bit.

Yeah, with my G9, it might grab the bird, but may not get the eye focus I’m looking for. I’ll use zoom-to-focus to get the focus point. A little more manual, but I like the challenge, even though I’ll sometimes walk away empty handed.
