The question of testing the FF lens on a crop frame camera has been addressed on the Forum. I am curious about TAv. How do you determine the exposure that will work since what you set is, by definition fixed? I would have approached this on Av to get precisely the amount of DoF I wanted and permit the shutter speed to float, having dialed in about +1.5 EV to account for the bright sky. What you did worked but I'm curious as to how you got there?
Many thanks for that question, David.The question of testing the FF lens on a crop frame camera has been addressed on the Forum. I am curious about TAv. How do you determine the exposure that will work since what you set is, by definition fixed?

The simple answer is that I find TAv easier to use as it gives me control over both aperture and shutter speed.
As you rightly say the aperture will control the DoF but as there was a slight breeze I wanted to keep to a reasonably fast shutter speed as I was using the camera hand held.
I may be lazy but I have found that 1/250s at f/8 gives me that combination that works under the greatest range of conditions when I don't want to use a tripod.
As regards this image I did also use a bit of PP to lighten the shadows and enhance the vibrance, etc !
I hope this sounds sensible but I'm always open to being taught otherwise ?
Thanks again
Peter
