DOF inconsistant between viewfinder and captured image

Has anyone come across this or similar phenomena - I'm using a Canon 7DmkII w/Canon 100m Macro EF 1:2.8L IS USM + stacked Kenko Extension tubes (12mm+20mm+36mm). The DOF through the viewfinder appear much shallower compared to the captured image? Is this a result of the extension tubes?

This image was shot at f/9

camera set to f/9 - I have no idea what the actual aperture would have been

The lens stays wide open until you press the shutter, then it stops down, takes the picture, and opens back up again. If you want a DOF preview, you should be able to program a button to give you that. My cam gives me a dof preview when I half-press the shutter button.

Thankyou!

This.
You always see things through the viewfinder at wide open apertures with today's cameras because of how the metering system and capture system work.
With macro, the wide open effect on the viewfinder will cause the issue you've noticed; more DOF in the final image than you thought you were capturing, since you don't see it properly stopped down without a DOF Preview button.
Conversely, today's camera viewfinders are optimized for viewing f/2.8 apertures. Because of this, if you shoot fast primes wide open, you will see more DOF in the viewfinder than you will capture in the final image, even if you use a DOF Preview button.

if you want the whole fly in focus get magic lantern and do some stacking.
is this pinned correctly?

what the fuck is wrong with the 100m Macro EF 1:2.8L IS USM

When 90% of all macro lenses are 2.8, why the fuck would you even engage a comment like that in discussion?
>>
>>2750361
because i didn't know 90% of macro lenses were f2.8
