Format Equivalent Depth of Field: APS-C vs Full Frame

Making Sharp Images previously discussed several key areas involving depth of field:

• What are F-stop and T-stop?
• Format-Equivalent Depth of Field and F-Stop.
• Depth of Field at the Periphery
• Depth of Field with Real Lenses (including Delay in DoF by Double Image Bokeh and Delay in DoF by Color Divergence).

Previously demonstrated were the format-equivalent apertures and depth of field for Micro Four Thirds vs Full Frame.

I am now gruntled to present this companion study which shows format equivalent depth of field and f-stop behavior using two 24-megapixel cameras (APS-C and full frame):

Case Study: Format-Equivalent F-Stop: APS-C vs 35mm Full Frame (Pellegrino)

Gear for this study: Sony A6000 with Zeiss ZM 35mm f/2 Biogon comparing to the Leica M Typ 240 with Leica 50mm f/2 APO-Summicron-M ASPH. A more in-depth study of the two lenses is found in Guide to Leica.
