Hi, so as the title suggests.... i want to shoot some macro shots of bugs/spiders etc in my yard using the 580exII with my Canon 80D

Im kinda new to trying this and after getting so many blurry useless images, im here to get some advice from those who know

Gear Used:
* Canon 80D
* Flash - Canon 580exII
* Lens - 60mm macro
* Other Lens - Kit lens 18-135mm


So this is what ive been doing:

- Connect my flash and turn it and the camera on
- Press the high speed sync button on the flash ( the H with the bolt symbol ) on ETTL mode

Camera settings:

- ISO set to Auto
- Aperture set to fastest - like 1.8 - 2
- Shutter.....not sure what i should do here..... but prob about 250

Result:

Still getting mostly blurred images, its not that windy really so its probably from me moving?


What i want to do:

I want to handhold focus stack some images to process in photoshop later. Im under the assumption that i need a flash to enable me to capture subjects without blur. Also under assumption that i need to use high speed sync to do this.

Advice on how to do this with the above mentioned flash and advice on camera settings i should try would be most appreciated

If i have forgotten to add information needed to help me please let me know

Thanks in advance.
