I use 4 EOS R5 camera for focus stacking application.

each view point i will tether 25 pictures. so every view point i have 100 pictures.

When I’ve tethered 20 or more view point , the software slow down or the UI stop response.

I found some tricky to solve the problem.

Every 100 pictures tethered,then hide them in the “photo tab”.

Would this issue can be fix, or there is some settings can aviod this problem?

Thanks.
