Kevin, nice whipbird. I've only ever seen one with a camera in hand, and all I got was a grainy slightly OOF shot, lost in the gloom . . .

Still, a picture of a whipbird with a camera in hand would be pretty special ...

The writers description is very apt. I have often seen orange/red flashes without realising just what they were. These birds move so fast and are never still. Took a couple of hours just to get these huge crops. This article may be of interest:

Early European settlers in Australia called rufous fantails "mad fans", because of their wagging, fanned tail and the fact that they never sit still. They chase insects on the wing, whirling and whizzing, making u-turns on a vertical plane, zooming with wings in arcs, their tails ablaze with a circle of rufous orange. They look like pinwheels twisting through the forest on the wind."They're incredibly high energy, hyper; they rarely sit in one place for more than a second," says Lindsey Nietmann, who is writing a PhD with the University of of Washington on the birds.
Rufous fantails (Rhipidura rufifrons) have cousins all over the Pacific. In fact, subspecies of these twitchy creatures are dispersed across Papua New Guinea, the Solomon Islands and the Mariana Islands.They used to be on Guam, a tiny island in the ocean between Papua New Guinea and Japan, until disaster, in the form of the brown tree snake, struck. After World War II, at least one pregnant tree snake stowed away on a US military shipment of scrap metal from Manus Island to Guam. Guam has no native reptilian predators. The snakes flourished and ate every single bird they could get their fangs on. At their peak there were 100 snakes per hectare, leading to the extinction of all but one of Guam's bird species. One of the birds that perished was a subspecies of the rufous fantail, and will never exist again.
At Iluka on the NSW north coast lives one of the two subspecies of rufous fantail in Australia. The same species of snake that was accidentally released on Guam lurks in the forest, but the Iluka fantails show no signs of imminent serpentine-caused extinction. In fact, the area has the highest density of rufous fantails that Ms Nietmann has seen in Australia; she estimates two to four individuals per hectare during peak breeding season.
Ms Nietmann is seeking to understand why the Australian birds survive when the rufous fantails of Guam were eaten into extinction. To do this, she is studying both the Iluka fantails and their cousins on Rota, an island just north of Guam that has only avian predators. She is monitoring the breeding population's nest-building activities, their egg laying, how many chicks they have, how much food they feed each chick and even how long the young stay in the nest.
Any one of these small details could contribute to the birds' continuing survival. "If you think about the chances of a predator finding the nest, those chances are much higher if the nestlings are in the nest for longer," Ms Nietmann says. "And indeed, they're in the nest on average on Rota for two or three days longer than they are here." Those two or three days could be the difference between getting eaten or being able to flee a threat. It's possible that Australian rufous fantails have evolved to get their kids out of the nest quickly in response to the plethora of predation threats.
But it could also be that rufous fantails of Australia have selected, over thousands of years, for a bit of lateral thinking — perhaps they're more canny when it comes to avoiding getting eaten. Ms Nietmann is testing the predator awareness of the fantails by presenting them with known and novel predators to see how they react. These include a yellow footed antechinus (a known predator in the area) and a chipmunk (from North America, which the fantails will never have seen before). It's a bizarre sight, watching a taxidermied chipmunk slide towards a nest on a piece of plastic pipe in the middle of the Australian rainforest, but Ms Nietmann believes her study could explain the species' survival. After all, if you can tell that a chipmunk is murderous straight away, it gives you a chance to take evasive action and, over time, save your species.

Thanks Dennis. Yeah, I didn't even realise that they were a bird until they landed for a split 2nd. I thought they were some giant glow worm or something? :lol:

I'm loving the 6D for it's speed of focus in the dark and ability to clean up nicely. IMHO, I'd say it's a much better buy than a 5D3 and I'm certainly getting more keepers with it. I love my 7Dll for reach and open and dry forest but it's practically useless in the darker parts of rain forest with the extender and f8 so I prefer shooting wide open with the 6D and cropping more

Dunno about the Markll Dennis? I certainly wouldn't pay more than double just to upgrade and with the price of the 6D dropping? I only paid $1100 for mine

There's a lot of conflicting info out there with regards to this lens and teleconvertors on the 6D so I thought I'd post this here and on the 6d thread. The Kenko 2x pro300DGX does work with this combo.......or at least it does with mine, despite Kenko saying it doesn't. It hunts like buggery in poor light but is fine in good light. It's howling a gale out there atm so at f11 and slow shutter speed, no use testing quality yet but I will post some asap

Cool... I'm glad I didn't sell mine then. Oh... wait... You are referring to the 2X... never mind. ;) I have the 1.4X.

I haven't checked. Does the 6Dc focus at f/8 with center point and 1.4X on the 100-400ii?

I'd better follow Kevin's lead and post my own finding in both relevant threads. Short answer to Phoenixh's question, is no - not for me anyway...

I also have a 6D, a 100-400 mkII and a Kenko TC. However mine is a 1.4x Pro 300 DG (ie not DGX), and while single point autofocus works on my 80D (the body recognises that the TC is present, and only permits centre-point autofocussing), my 6D will NOT autofocus with the TC, regardless of any settings that I have tried. The 6D is aware that the TC is there, as the maximum apertures change.

I have just had the 6D firmware upgraded to 1.1.6 (I think it was previously 1.1.3) but this did not change this refusal to autofocus. My lens firmware version is 1.0.6. (The camera does not report the TC - do they have firmware?)

By contrast, my 6D will autofocus with my Tamron 70-200 and the Kenco 1.4X TC, but this is an F2.8 lens. In this case, the max aperture stays at F2.8 (on both bodies), so the Kenko is invisible to the Canon bodies, but only with a Tamron lens!

Cheers Alec

Dunno? my 1.4 is canon and it won't autofocus with the 6D

Also on 6D thread. Never used a 2x before but love the extra reach over my canon 1.4

Still waiting for a bright enough day without wind to give this a proper test but I can confirm that in full (bright) sunlight it will autofocus with centre spot. With manual selection autofocus (all spots selected) it focuses fairly fast in dimmer light and at full stretch and with a minimum of f11 I guess it is up to the user as to whether allowing the camera to pick auto spot is OK. For me, shooting birds and filling the frame with them, it may be useful.

I was out in the garden testing it's focusing speed when this feller came into the viewfinder. Not up to 7Dmkll and canon extender standard but I had all focusing spots enabled and it was pretty dull so it looks promising, but more to follow under better conditions hopefully

OK. The sun came out but no birdies. :lol: Also posted in 6D thread

Yes, it will occasionally focus centre spot in strong light but can hunt like buggery and not really worth the bother if you're going to miss shots. Using all spots engaged, it is fairly fast at focus for f11 but strangely, always seems to pick an outer spot although I would have thought that the centre spot, claiming to be more sensitive, would be picked every time? Not once did it pick centre? Any ideas why? At first I thought perhaps it's opting for the nearest focus point but in the first pic, it's clearly picked the furthest? Can't fault the quality unless after huge prints for < A$200 as I could never stretch to the canon.

Last two are 100% crops. I was about 15 yds away for the pink flower and didn't even see the bee with the naked eye!

Will try taping the pins tomorrow to see if centre spot works

No exif but I'm presuming because they aren't public at flickr? All at full stretch 800mm

Completely spoiled! In my search for longer reach I've been researching the Tamron and Sigma 150-600 as they would fit within my price range. I was within a hair's breadth of opting for the Sigma but...............and this isn't to knock other people's choices...............​I don't think that I'd ever be satisfied with another lens now that I have used this.

Once the proud owner of a hasselblad system, I had exactly the same problem 35yrs ago when switching back to 35mm and opted forever only to own primes.

Just before pressing that "buy" button on the sigma, I decided to search the forum on both the Tamron and the sigma putting more faith in the forum user's images/comments than on professional reviews. Glad I did! There's some excellent photographers and images on both, but the IQ bears no resemblance to the images that I have seen on this thread, and yes, I know that there's a huge difference in price between them, and canon L glass, and the tammy and sigma are a compromise, but I personally, just can't compromise IQ for better reach/cheaper price.

Once again, not knocking others' choices or the lenses, but simply trying to illustrate just how great I think this lens is and possibly, or should I say, more than likely, just how anal I am with regards to IQ :oops: :lol:
