Thanks for sharing that Rik, I’ll contact them to get more details on compatibility with my system.

What bothers me much more is that it can take only 1 shot/second in the fastest mode.
What an odd limitation. Olympus and Panasonic have no such limitation.
it seems I was wrong, here: https://helpguide.sony.net/ilc/2230/v1/en/print.pdf it states:

"Shooting Interval:
Sets the shooting interval when shooting with the focus bracket. ([Shortest]/[1 Sec]/[2 Sec]/[3 Sec]/[5 Sec]/[10 Sec]/[15sec]/[30 Sec])"


so with "fastest" stacking will probably be much faster than 1 frame/sec =D>

Rik, Ive been studying many of the articles (you, C. Krebs, and others have written) on the website that are helping a great deal with improving stacking workflow. In your article above where you are stacking the eye of a painted lady butterfly, the small LED lighting seems straightforward. Are there any that you would recommend that are small and easy to use like the one in the article? Home depot has a few like this:
https://www.homedepot.com/p/Newhouse-Li ... /308862933 that has adjustable lighting.

Ive not used LED lights before … is there a color temperature range for them when shooting? Im using a Canon MT-24EX Macro Twin Lite Flash with lots of diffusing material added to the lights.

Thanks

In general, LED's can have problems because of flickering (depending on how they are driven), bad color reproduction (due to a bumpy spectrum), low brightness (leading to long exposures that show mechanical vibration and accumulate sensor noise), and changes in color over time (due to gradual degrading of phosphors inside the LED). My experience with the Ikea Jansjö's has been quite positive. I wish they were still available. Perhaps the unit at Home Depot would be equally good, or perhaps it would have one or more of the problems. Unfortunately I have no experience with that particular unit so I have no idea how it performs. Likewise for all other currently available units. Sorry about the lack of current info!

Ok, thanks. If I get it, I'll report back on the results. I can always return these to the HD if it doesnt work.

I have Sony A7IV and M1 Max MBP
That's a bad omen for automatic shooting. Sony is notorious for not providing in-camera focus bracketing, and not providing good hooks for anybody else to do it in their own software. The only controller I know that will do it is the CamRanger 2, as described at https://camranger.com/knowledge-base/fo ... m-cameras/ .

If anybody knows different, I would appreciate knowing also.

There is a workaround which I used quite a lot -- https://www.andreasmariotti.de/automati ... owershell/
For example this is 45 shots with the A7 III - https://photos.app.goo.gl/bYsB4AvhCEFLTnui8 Click on image to see higher rez.

Now finally it is implemented in camera from A7RV
