Jewel Amongst Moss Capsules
I recently used my Raynox MSN-505 on a 210mm lens at f16:
This was with it on my Olympus 50mm macro fitted with its x2TC.
This individual capsule had opened, retaining all of its golden apical threads. Behind it is a capsule with the conical cap still in place.
Olympus EM-1 (manual mode), Olympus 4/3 x2 TC, Olympus 4/3 50mm f2 macro, f16, MSN-505 twin flash hand-held.
The first image is a crop of the second one (FOV 5mm wide).
