Nice shot! I like the metallic sheen on the Grackle - we have a number of birds with similar plumage. I read a book recently which spoke in great detail about how Australian birds tend to be much more aggressive in general than birds in other countries.

Thanks! I've seen Grackles in the south-east of the USA. I think they're a bit smaller than Currawongs, but I can see the similarities. Despite their looks, Currawongs aren't aggressive toward people that I've ever seen. Lots of other Australian birds are, especially in spring - the worst offenders being the Australian Magpies, which will attack anything that moves near their nests.

PS The Grey Currawong is quite uncommon, but the Pied Currawong is very common. The Pied Currawongs often have what I call "Currwong Corroborees" where they gather in groups of a hundred or more and call incessantly. I've no idea why they do this, because normally they don't travel in flocks or large groups.

Tidbinbilla has recovered to a degree, but it will take decades for the forest to come back to what it was. I did correct the name of the Bandicoot - thought I fixed it on Flickr but I realise it's wrong at the moment.

Thanks - usually, male Flame Robins pop up at a distance and they're hard to get close to. I was patient and stood around for a while until they got used to me presence, and one got close enough. :) I have a couple of other nice poses, but this one certainly is the best for detail. The first time I saw one was at Barrington Tops - at quite a distance.




Thank you!



Thanks! I'm really glad I got that lens.

Thank you! I certainly can't claim to have a magic touch with the other kind! :lol:




It depends on how long it takes to spot the next bug from their vantage point. :) They didn't like me getting close, so most of my photos didn't have anything like this resolution. Patience paid off!

OK, most of my use of the long end of telephoto or zoom lenses is at longer distances, so I don't think I've had any circumstances where this is a concern. You might want to check this article;

I was also going to suggest the Pentax 55-300 PLM. From the reviews of the Tokina lens, you may get results from the PLM shooting at 300mm and cropping.

Thanks! I hope that large sanctuaries like Mulligan's can help save species from extinction. I wish foxes, cats, pigs, goats, camels and rabbits never ended up roaming free in Australia. :(




Thanks! I saw them previously at night, when it's a lot harder to take photos.

Thanks! The sanctuary is 485 hectares, and Bettongs are nocturnal, so I count myself very lucky to see two in daylight. :) Sorry to hear that you haven't seen the birds you've been looking for. When I saw the Bettong I was heading back to the car, which happened to be westward. I tried to circle around to get the sun behind me, but he hopped away. I do have another photo of the second Bettong in shade, but of course it doesn't have as much detail or clarity.

Southern Bettong
by RobGeraghty, on Flickr

I'm so excited to get a good photo of this endangered species! A population of the Southern Bettong was introduced to Mulligan's Flat Nature Reserve from Tasmania. The Bettong became extinct in mainland Australia due to predation by Foxes. Mulligan's Flat sanctuary has an electric fence around it to keep Foxes, cats and rabbits out. Bettongs feed on truffles, roots, grubs and insects.

Hi Todd - could you please elaborate on what you mean by focus breathing? Do you mean hunting? As in the lens goes in and out of focus without achieving lock? I haven't noticed this with the DFA150-450 and the DA HD 1.4x TC. However, I haven't actually used the TC a huge amount with the lens, because 675mm is often enough focal length, and the TC adds a bit more weight as well as affecting the aperture. I haven't tried the TC with the PLM and frankly I wouldn't expect it to work. The TC works with the DA*300, but the combination does tend to hunt, and that's why I have seldom used the DA*300 since I got the DFA150-450. The DA*300 hunts even without the TC, and its painfully slow motor makes the hunting incredibly annoying.

I've taken "macro" photos of flowers with the DFA150-450 at minimum focus and don't recall having issues with hunting for focus. I recently had Fairy Wrens hopping around at my feet and it was hard to get them in the viewfinder at that angle and distance.

It's a brilliant lens. Great AF behaviour, sharp and rich results. If I want a long lens which is light, I go for the 55-300 PLM.
