Hi,
Performed procedure suggested by Chuck a few weeks ago--steady light on
interior wall. Best estimate with OM-2 meter.
50 mm Macro/3,5 at 1/2 Mag -2/3 stop (Due to extension in the lens itself).
1/4 Mag -1/3 stop
1/6 Mag -1/3 stop
<= 1/8 Mag 0
Tamron SP BBAR 2X TC -1 stop no surprise
Tokina 2X TC 4 element -2/3 stop Hmmm
25 mm Ext tube -2/3 stop
More to go,
Mike
PS
Maybe I will be able to consistent non-TTL Macro flash fill in this lifetime.
