Vdo1, How is Tina's health ?
Tina is doing great, today she got chestnuts and unshelled walnuts. The chestnuts she squirreled away to her hollow in the tree so I couldn't see how she's eating those. I'll need to follow up until I could get a pic of that
Unfortunately it was dark and raining here for a couple of days now, I can't really take pics any more, as ISO would be too high and the glass door is covered with rain droplets and dirt too. Figured out that I need to close the aperture to 5.6 for sufficient DOF and also keep time shorter than 1/125s, Tina moves quite a lot and pretty fast. Anything under 1/125s is motion blurred.
The other day Tina brought a friend, a black squirrel. She was moving even more, one second she was still, the other second moving. One of the few times I had to use burst mode.
Here is the black squirrel shaking the snow off her head, 1s time difference between the photos as per EXIF:
And I've also learned a few things about black squirrels:
Also noticed myself that their claws are light in color, nearly translucent, like our nails; while Tina has dark claws.
Anyway they're both welcome here.
And I'm now planning for a Sigma 100-400 so in the spring I could sit out in the backyard and take pics in the open without the glass door interfering. Figured out that 100mm is a little bit short for it, guess I need to be in the 200-300 range.

I have no cute little squirrels in my backyard. So I must improvise with what I have.
I have shot focus stacks for landscape images. and hand blended them. I wanted to try a focus stack in macro using the align and blend functions in Photoshop. So below is my first attempt.
This is a 4 shot focus stack of a Dandelion that was growing in our lawn. It looks like it could have used one more shot between frames 3 and 4. Still not to bad for a first attempt.
I used a pillow from the couch for the red background. I thought the soft cloth being out of focus would make for a painterly contrast with the detail in the Dandelion. I manually exposed for the background. You will see from the shutter speed that it was pretty dark when this was shot. I used my ring light to add some punch and detail to the Dandelion. I used my macro focus rail to control focus position rather than refocusing the lens. I though this might give me better control.
Unfortunately the resolution on the web doesn't show that incredible detail and sharpness contained in the full resolution image.
It was a fun exercise, showed me how much I have yet to learn about this macro stuff, and a good way to waste some time during this lockdown period.

An Art DG DN 50/1.4 with similar optical design goals would be an instant purchase here. Sigma please take my money!
Same! I purchased the 85mm DN due to GAS, but I will probably swap it with a 50mm DN once they release one. Hope to pair it with a future 135mm DN or 70-200mm DN as well.

It looked like a decent sunset was developing this afternoon, so I decided to go for a walk along the coast. I took only the Sigma 105mm f/2.8 macro in order to try and shoot it outside what I have been doing. Ok, I admit I put my CV 40 f1/2 in my jacket pocket just in case. Never put it on the camera however.
A big low cloud band came in a ruined the sunset, so I switched to wildlife. It is the beginning of breeding season for the Pelicans here, so they are beginning to display their best colors.
This lens is so sharp, but it also has very nice rendering resulting in a wonderful 3-D feeling to the images. It is going to be a super portrait lens also from what I am seeing here.
Enjoy. Let me know what you think of this lens for wildlife and the rendering.

I sold my Sony 85mm f/1.8 and replaced it with this lens. Haven't really been able to shoot with it much (outside there's only couple hours of light and bleak dark nature without snow), but when I shot with it outdoors with my daughter (my earlier post in this thread) I came to conclusion that this lens is a superb portrait lens with lovely rendering. Esp. medium-long distance it is way better than the 85/1.8 ever was, which had rather harsh rendering when not shooting close ups. And sharpness and lack of almost any visible CA or loca is pretty stunning.

Is there any reason to buy this Sigma 105mm over the Sony 90mm? Maybe better bokeh for portraits on the Sigma?
In terms of CA they both appear to be APO unless I am missing something.
I can currently get the Sony for ~700$ brand new, whereas the Sigma would cost me 900$.

From what I could gather from online sources, the Sony is far from being APO. Looks to be at about the level of the Sigma 105 OS and Tamron 90 VC.
The new Sigma seems better but still has some LoCA, especially in specular highlights.
That being said, I am still very interested in more LoCA details and comparisons.
If no comparable macro lenses are available, I would be interested in a series of shots of a contrasty scene with apertures from F/2.8 to F/11 that shows the progression of LoCA with aperture.
(Full size images or crops of the focus transition zone would be ideal)

I posted wide open for the Sigma compared to the CV 110 APO. If you would find that comparison useful across f/2.8 to f/11, let me know, and I can try to oblidge.

Hey Tim, yes, that would be very useful.
Also, would you be willing to do some LoCA-vs-aperture comparisons for a real-word close-up subject? Maybe a flowering plant, or anything with details and colors, so LoCA can be judged well. I would really appreciate it.
Cheers
