Topic: Clubman 28mm + x2 (x2 TC's)
The lens is very sharp & gives in a lot of light so I thought I'd give this a try... the TC's are both Vivitar x2 - 21.
I'm not sure whether I have strange results with parts of the image in the first shot with focusing... the leaf & feather are both behind the Lichen yet are partly in & out of focus as is the Lichen? The Lichen is no bigger than my finger nail, the stems are 0.5/1mm tip to 2mm +/- at the base.
Very bright sunny day... the only one so far this year...
My wife thought I'd finished after the first shot & removed the feather... displaced the Lichen... ooops!
