About

2019 iMac 5K

I use Zerene Stacker heavily for focus stacking and it takes minutes to do some stacks, so speed here matters a lot to me. Since I stack mostly with the DMAP method, this test is most appropriate to my own work.

Results

 

The latest optimized build of Zerene Stack delivers oustanding gains from more CPU cores, with the 2017 iMac 5K taking 2.1X longer than the 2019 iMac 5K. Big win for the 2019 iMac 5K!

This stack uses 20 16-bit 45-megapixel images from the Nikon D850. See Nikon D850 'Focus Shift shooting' feature for Easy Focus Stacking.
