I've changed lenses.…I've got the Canon 50mm f/1.2.…I had the 1.4 earlier.…I changed because of the filter size and you'll see why in a little bit.…But I'm going to start by reversing it and taking a picture.…I'm in Aperture Priority.…I've dialed in to F8, hitting my Depth of Field Preview button and taking the lens off.…This should all be old hat to you now.
