Anyone able to help ID this one from today? Butcher bird?

K-S2, FA*300 f4.5, Rogue Safari flash extender:

It appears to be a Grey Butcherbird (Cracticus torquatus).

Second one is AWESOME!!!!

Good lens actually. So far I have only taken some test pics on my old 12MPx Lumix G1, though the FD adapter for my NX20 arrived today, wasn't expecting that to arrive from Hong Kong for at least a week. Impression is this is my best lens at 400mm, as this 100% crop at f4.5 indicates:



And while I was in the vicinity of the castle I was able to snap the swans.


A 100% crop, at f8 I think:

Now the plan is to attempt a mount swap. Fingers a bit twitchy at the thought of messing with a £180 lens rather than an £18 lens but from what I've read online the mount comes off easily. Watch this space...

It's probably been a month since this photo was taken!
A great outing with @RockvilleBob at Assateague Island National Seashore.

Weather had been great lately! Looks like rain tonight though...

Another one from my last trip to Assateague.

Times like this I wish I had the DFA100... And some morning dew to really bring out that lighting.

Many thanks, Pete ... I just looked at your profile, and you'd know! :-D

Definitely a butcherbird, based on the colouration and you being in Melbourne I'd lean toward Grey rather than Pied.

Thanks, Mike, for the expert corroboration!

K-3 and Tamron SP AF 300 2.8 coupled with the HD DA 1.4 TC (420mm, ƒ4)
ISO 400 , most images taken at ƒ8 (lots of light with a layer of reflective snow) and shutter speed most at 1/1000s some as low as 1/500

I saw a Fox Sparrow a few weeks ago and then not again, which had me thinking the season was over for them. But this morning, there one was pigging out in one of the spots I keep snow free for the ground feeders.









He was joined by only one Junco, there are usually at least 4 or 5, sometimes as many as 20.


The usual huge congregation of Nuthatches Chickadees, and Blue Jays was also in progress. As well as one of the Hairy Woodpeckers.











At the time there was only one squirrel, but I see looking out the window, there are a lot more now. Because of the lack of squirrels the up to 12 Blue Jays pretty much had their run of the place.

The squirrel early riser. The rest of them must have slept in.

More swans, duck, gull, this time with the NX20. Cloudy today. f stops estimated from the shutter speeds.

F8


F4.5


far side of the tidal creek. Original crop was 1687px. F8


No crop. F8


1:1 pixel peeper crop. F8


While some fringing is a regular occurrence, it was dealt with very easily by lightroom, using the defringe and red-cyan slider.
The CFD-NX adapter allows me to use the lens like an M42 - the adapter has a ring that stops the lens down like an A-M switch and which I can push with a finger of my right hand while the left focusses.

Couple of Eurasian cranes looking for a suitable field area for landing. K1+DFA150450+TC (60% crop).

Just curious - what is the difference between no crop and a 100% crop? I need some help understanding percentage crops - is there a single definition? What is a 20% crop - to me it is an image that is 20% of the original image area as opposed to a crop representing 80% of the image area. I always see the term 100% crop and depending on how you look at it would seem a 100% crop would be the full image or no image.

I think common usage is to say "no crop" if there has been no cropping of the original image, and a "100% crop" is a maximum pixel size crop from the original ie the duck was a 1024px wide crop out of the original 5472x3648px image. The point being that it illustrates baseline IQ, so to speak, as resolved by the lens + camera. Resized images will always converge in resolution.
I agree this is a bit undefined given that I would also regard a "50% crop" as being an image that has been cut down (not resized - that would be "resized 50%) by half (and I think most people would mean in terms of a linear dimension rather than area).

When you think of it a 100% crop would be deleting the whole image. I often refer to a 1:1 pixel peeper crop because it would be a pain to work out the percentages. I guess I could say it's 1200x800 image that is a reduction of 100% of the image. Maybe that's where the 100% crop comes from.

1:1 pixel peeper crop

Much less ambiguous normhead.
