Three Patagonian birds with "Austral" (="southern") in their name:

Austral Thrush (very much like the American Robin)



Austral Negrito



Austral Parakeet - the world's southernmost parrot species





K-3, DA*300m + 1.4xTC

Yes, that Austral Thush is shaped so American-Robin-like that it could be mistaken for one in dim light. The beak is just a bit stubbier. That's the only anatomical difference I can see from that angle.

It was a beautiful December day so I drove 2 hours to Conowingo Dam for another attempt photographing eagles arriving at 7 AM. However the dam stopped releasing water at 8 AM so the eagles were scarce and I left around 10:30 AM. I did capture both an adult and juvenile eating a fish on a branch. They both dropped their fish. Notice the difference in behavior. The adult knows there are always more fish. The adult shot was at 600mm and is cropped since it was high in the trees. Sometimes you have to shoot with what is in your hand. The juvenile landed a few feet away when I had added the 15TC so I was shooting at 900mm. The juvenile image is without any cropping.

Very nice shot...love the colors. How do you like the D FA 150-450? I can't decide to buy DA L 150-450mm or older prime SMC A* 600mm f/5.6. I shoot mostly wild birds so reach and sharpness is most important. I can live without autofocus.
How sharp is 150-450mm shot at 450mm wide open aperture?? Does it need to close aperture some to get sharpness at full telephoto (450mm) ??
Any info would be greatly appreciated, thanks.

I'll but in here if I may.
I shoot with the 150-450 + 1.4xTC (630mm, or 945mm at 35mm equiv) and most of the time wide open (f/8.0), and get nice sharp images.
Here's a sample, shot using K-1. This is a large crop, 2166x2888 out of the original 7360x4912.

Cheers,
Terry

Thanks Terry for the respond. I have few more months to decide before I pull the trigger and buy new lens. I wish Pentax would come out with new 500mm or 600mm f/4 with fast focusing like new HD Pentax-DA 55-300mm F4.5-6.3 ED PLM WR RE.

Mmmm.... I consider it a good solid lens, but not magical. I notice the IQ improve from WO to say, F8, more so than with my F*300/4.5. I also notice it"s light transmittance for a given aperture isn't prime like....lots of elements. To some extent, these are the things one trades for focal length flexability. A much better lens on my K-1 then K3.... maybe the next K3 generation will change this..... it gets a 8.5 from me....

I look "lustfully" at 600/4 shots and then have to reframe my reference back to $2k lens versus $6k lens..... a bit like 55-300 shots compared to DA300/4 shots.... anyway..... I like the flexability a zoom brings at this range of focal lengths for my situation....

That would have to be an $8k lens....

Yes, either would be a nice addition, but you certainly wouldn't be using a 600 f/4 handheld like you can with the 150-450, and also with the 1.4xTC.
Here's another example, shot with the K-3 II, with 1.4xTC and full zoom.

Cheers,
Terry

That's awesome!

I can't wait to get out there... I've heard it's one of the best spots for eagles.
How often do they release the dam? Is it a predictable occurrence?

Guanacos - all with the K-3 and DA*300mm - the 1.4x TC was added for the first one.
