The birds were very camera shy today. I was only able to catch a couple.

Tufted Titmouse

Really nice captures, Jerry. Good compositions.
Question, when zoomed in I see artifacts, not that unlike i.zoom
Was Clearview zoom (or whatever it's called ) used? I believe its a form of digital zoom.
All of these images have these artifacts. Or perhaps these were all cropped quite a bit?
Not wanting to be picky, but i have a bad habit of zooming in to see the feather detail in just about every bird shot i see.
Doesn't take away from you or the really nice images, but I mention it, since i see it, and wish I didn't...just like some of my images.
When I under expose the FZ80 to get faster shutter speeds....often the noise creeps in..I can't help but see it ...and I don't like it.
Having the D3400 with it's excellent 24MP APS-C sensor doesn't help, as that can shoot at ISO 3200 and have less artifacts than my FZ80 at 800
But I won't use my FZ80 at ISO 800...too noisy.

There are probably two possibilities. Yes, I might have had the CIZ turned on for these and secondly I added a little sharpening from FastStone.
I believe, like i.zoom that CIZ is the reason for what I see.
Here's a couple SOOC shots for comparison. I hope you clicked on the ORIGINAL file, as the DPR displayed file has lots of smudging.
Always click ORIGINAL SIZE Jerry. Yes, otherwise DPreview does something when images are posted here.
I also shot them through a double pane window as it was too cold to be outside today.
Not the artifacts I am seeing. But could be the reason for the need to sharpen more in post.
See if these have less artifacts.
They do..but are on the soft side. I see why you sharpened them.
Still...excellent captures, Jerry!
You are the third person I brought this up to...in the last few weeks or month.
I mean no harm...no finger pointing...just want to make aware what I see.
Thought I posted about using i.zoom a while back, but can't find the thread .
Think i will start a new thread , based on using i.zoom....EZ Zoo...digital zoom...and just optical zoom...maybe give samples of each, too.
I just to show using it, most times, it becomes a double edge sword. It allows for more reach, but at the cost of detail and artifacts.
Not sure about the Sony RX series, but with the Panasonic, they give you a warning, before you go past optical zoom, into i.zoom (same for digital zoom). Nikon does something similar. Forgot if Canon does.
Funny, how they don't show the bar on top, when you use EX or EZ Zoom. No need for a warning to let the user know I.Q. might take a hit ?
Really Panasonic?
Oh....perhaps because
EX (EZ ) Zoom feature doesn't deteriorate the I.Q. like the other ways to get more reach does.
I see. that's why I promote not using i.zoom...but instead to try and use EZ Zoom.
Always welcome Jerry. Hope i didn't offend...i didn't mean to.

Again, nice shots and good poses, Jerry!
