[QUOTE="Eyelight, post: 424830, member: 24753"] For all who wonder, [URL="http://nikonites.com/macro/29148-1-1-f-36-versus-1-2-f-8-cropped-post424324.html#post424324"]Post #8[/URL] is a fair summary of the why and the what of the thread. It's essentially a spin-off discussion brought here to minimize the impact on the former thread. The DOF is [B][COLOR=#ff0000]not[/COLOR][/B] equal.

The flower images in Post #1 show this quite well and your bit images also show it very obvious in the two full shots in post [URL="http://nikonites.com/macro/29148-1-1-f-36-versus-1-2-f-8-cropped-post424564.html#post424564"]#21[/URL], because if the DOF's were equal, then the blur in the 1:2 shot would actually appear less than the blur in the 1:1 shot.
