The latest update to my Canon EOS tethering app, Kuuvik Capture, is now available for both Mac and iPad.
With this release, we’re starting to roll out a new focus bracketing engine. Building on new features of the DIGIC 8 and DIGIC X processors, Kuuvik Capture can now execute focus brackets with the mirror locked up during the entire bracket (on DSLR cameras), saving time and reducing mirror wear. The new engine is initially available for the EOS-1D X Mark III and 250D/Rebel SL3/Kiss X10/200D Mark II. Of course we’re planning to bring it to other cameras as well in the future.
The new engine also drives focus bracketing for the EOS R5, much faster than the old one did. Electronic shutter is supported for focus brackets with both the 1D X Mark III and the R5, resulting in minimal shutter and mirror wear, and rather quick operation.
Firmware for DIGIC X-based cameras unfortunately still full of bugs hindering proper tethering operation. A newly discovered one is that once depth of field preview is engaged, you won’t be able to move around the point of operation (that is, can’t move around in live view when zoomed in, or can’t jump to a marker). This is a rather serious oversight from Canon.
We’re mitigating this issue by automatically turning off DoF preview when it would break the operation you are going to perform. For example, one typically uses DoF preview with the jump to marker feature to be able to assess depth of field with the current focus placement. We faced a choice here, either a) jumping to a marker would silently fail when DoF preview is on; or b) turn off DoF preview and do what you asked for. B is a clearly better solution here, and we consistently do the same in case of all other operations where the bug would cause a problem.
On the 1D X III this bug also causes issues with multi-point live view, so we completely disable DoF preview during multi-point live view.
The update is free for existing Kuuvik Capture 5 users. We also offer an upgrade from 2.x-4.x to version 5.
