@pigeonhill Thanks for your flashing fast reply, also I had a look at your works on 500px, and found it fantastic!

The syntax error disappeared itself! Unfortunately, I did not get the problem!
The code is working now and I have the first automated focus bracketing on my camera.

Could you please help me understand what each parameter does in detail? (or give a reference if you have)
Is it a good idea to use this script for ultra macro (6x magnification) to stack about 100 frames at once?

Thanks in Advance

The script is not designed for macro work, especially at 6x mag. At that mag you should be using something like https://www.wemacro.com/

Thanks @pigeonhill,

Do you know if lua codes for lens focus work for all ef lenses with ef-m adapter or its just limited to ef-m lenses?

The EF lenses from analog times will not work,  :-X EF-S ... IS do.
The Image Stabilizer seems to be a necessity.
I´m using them with a Meike MK-C-AF4 adapter.  :)

Hi,

I tried to create a really simple script for macro focus bracketing on the EOS M3 camera, but I found the Lua code to be too complicated for me. I would really appreciate it if you could help me out, please.

Here's what I need:
When I run the script, I want the lens focus to go to the "Focus Start Point" that I specify. I also want the aperture to be set to its widest opening. Then, I want the script to wait for me to press the Fn button to start the focus bracketing. Once I press Fn, I want the focus bracketing, to begin with the fastest possible rate.

These are the inputs I need for the script:

Focus Start Point: The point where I want the lens focus to start, for example, 20mm.
Step Length: How much the focus position should move forward for each shot, for example, 1mm.
Total Shot Count: The total number of shots I want to take, for example, 5 shots.

Any help is highly appreciated

Please help. With original 1.2.1 firmware HDMI output is clean and nice, but with m3-121a-1.6.1-6256-full_ALPHA.zip looks like in the attached picture.

Looks like the OSD code isn't correctly handling the screen resolution.

Can you try the 1.7 development build? It uses a different technique to draw the OSD, so it might already be fixed there.

Can you tell what resolution the HDMI output is? These cameras normally use 1080i, but may fall back 480p with some devices (see https://chdk.setepontos.com/index.php?topic=13489.msg142685#msg142685)

I updated CHDK to never 1.7 but still the same result. I tried to take a dumb from camera and have a file called "M0132.CTG". As a capture device, I have Epiphans AV.IO HD which has full hd specs.

I was able to get it nice after changing the PAL to NTCS. Dont really know what else it might do. Is it possible to have it working with PAL?
