someone IDed that as a muskrat over on the wildlife thread and it does look to be a muskrat Thank you for the kind words Walt
I almost inserted a parenthetic "(?muskrat looks too small for a beaver)." Should not second guess myself, except when I'm right in the first place which does happen now and then.

An early start yesterday 05:45 and 7 hours of driving in total got me these. I'm feeling a bit knackered today.

K-3ii/FA*600mm F4 ED [IF]/ Eckla window mount.

Somedays, you go out for images of Beavers and Otters and all you get is the images you take waiting for them to turn up....

You'd swear it was duck dam, not a beaver dam.


There are always squirrels.


And my constant nuthatches and chickadees. I got these images with the K-3 and 55-300, trying to show a couple at the Cameron Road parking lot how much better you can do with portable lightweight lens then the 500-600mm glass they were using , in terms of getting the background etc., however, they remained fixed to their tripods in the middle fo the parking lot. It's fine buying expensive long glass, being committed to it's use when inappropriate, not so much. My images were taken buy ducking and dodging to avoid tree branches in the way. They kept complaining about the branches.






K-1 with Tamron 300 2.8 and Tamron 2x TC. Using that combo, I try and always use the 2 second timer (meaning I have to anticipate where the ducks will be in 2 seconds.). The camera reads 300mm instead of 600mm, and ƒ4 instead of ƒ8 and you can't depend on the SR. Considering it's a 2x TC the images are pretty good with the K-1. But that's it's limit, with the K-3's smaller pixels, I suspect resolution starts to suffer. But that being said, I bought it for use on the K-1 so I'm not at all disappointed.
And a pair of hooded mergansers out in Costello Creek. There is a place for long lenses, just perhaps not with birds as friendly as Nuthatches and Chickadees.

re: the 2 second delay: I wonder whether you might get the same results by telling the camera to use the mirror-up "electronic shutter" mode with a hand-held "bulb" release. Only disadvantage I can see is losing the viewfinder.

I can't see where the ducks are in the frame when the shutter goes either way.

For some reason PF's firewall has been locking me out for a few days. Back in now.
About time I posted a pic or two with my new 300mm 2.8 (see here). Not bad considering almost 1:1 crop. k3, f5.6, with sigma apo 1.4x tc.

Tamron adaptall 300mm f2.8 compare - 360B and 60B

Don't think I'm on fire normhead ...hey where's that smoke coming from...

X-post with adaptall club.
I have got round to doing some comparison pics. This exercise provided one significant learning point straight away. I also did pics with and without the internal 43mm filter. Take the filter out and the focus shifts. The correction is about 5mm of focus rotation towards infinity. So now I know why when I acquired my 60B, without filter, it wouldn't focus to infinity, prompting me to spend some time trying to fix it. The 360B is similar. IQ-wise however it is difficult to discern any difference between images taken with and without the filter with either lens.
Pentax K3, tripod mounted, focus 10x live view, with loupe, remote shutter. Export from RAW LR3.6, just default settings.












Actually if anything the 60B looks slightly better, but its very close and I wouldn't be conclusive on just one test. I must admit I was hoping that the 360B would show a bit more to justify the purchase.

I have been busy, so it felt good to get out for a few shots today. Great images lately everyone!

Some images were taken with 6D and Sigma 150-600mm Contemporary or with Canon 100-400mmL. I hope they look ok because I don't know how the program that I used to upload the images is affecting the quality.







Some images taken with 5D Mark IV and 300mm f2.8L + 2x TC or with Tamron 150-600mm (some of them are at high ISO).










Great series!

I got the EF2.0x III converter today. No birding yet, but a test shot. Coming from the DA560 + 1.4TC, this was going to be an important one, because the Canon 400DOII + EF2.0x at 800mm f8 is going to take the place of DA560 + 1.4TC at 784mm f8. For wading and perched songbirds, it has been an important combination of focal length and aperture for me. A 2.0TC is not generally part of a serious birding kit, only for the special shots, but I took a gamble that it would turn out right with the Canon EF2.0x III, which is regarded (with Sony's 2.0TC) as the best 2.0TC around, and would be at least as good as the 1.4TC on the DA560.

Here is a test shot on the 7DII at 2000 iso. I am pleasantly surprised to see no CA, either lateral or longitudinal, whatsoever in testing with the 400DOII + EF2.0x III, which was a bit of a problem with the DA560 + 1.4TC (mostly longitudinal, so impossible to clean up), and feel that it passes the critical detail test. Also, auto focus is still fast, responsive and mostly spot-on.
On the Sony A7rII, sharpness is even better, but auto focus is clearly not native, with quite a bit of travelling through the focus range, needing to set the limiter on the lens, and aid with manual forcus. Once in the region, it snaps into spot-on focus immediately.
Finally, the very, very good IS in the 400DOII really comes to aid handholding 800mm, making it almost cheatingly easy compared to the DA560+1.4TC, and the 7DII seems to get better at iso 800 to iso 2000 compared to the K3II, whereas the K3II is clearly better at iso 100- iso 200, and a tie inbetween. What the 7DII does very well, is hold colors at higher iso settings, where the K3 washes out above iso 1600.




Chris
Looks good. I have a forum friend who shoots with the 400 DO combined with the Sony a9 and gets really excellent results, even with the 2x TC. If the light is there, that lens really delivers.

K-3 with the Sigma 500mm F/4.5. Color moire formed on the bird feathers but Topaz Denoise is good a cleaning it up with the clean color slider.

I reduce the sizes of my images typically by more than 50% before I post them on flickr. This one was full of details. I believe F/6.3 is where the Sigma 500mm F/4.5 is at its strongest with the K-3. Higher than that I think the combo starts to run into diffraction.
Fantastic IQ!
