Standard shipping
Estimated delivery time: 3-5 days
The FOTOCORE OSD-M (Optical Shaping Device for GTM) is a compact precision snoot designed specifically for the GTM strobe. It gives underwater macro photographers stepless light shaping in a more compact form factor than the standard OSD, making it easier to manage on a crowded rig or in tight spaces.
Nine adjustable aperture modes allow precise, repeatable beam control from a broad wash to a narrow spot — ideal for isolating subjects, creating dramatic shadow effects, or painting selective light on macro creatures. The OSD-M attaches and releases quickly for efficient dive operations.
A lanyard neck attachment prevents accidental loss underwater. Best working distance is 150–200mm from strobe head to subject, the same sweet spot as the standard OSD but in a lighter, slimmer body optimised for the GTM form factor.
