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.\u003c\/p\u003e\n\n\u003cp\u003eNine 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.\u003c\/p\u003e\n\n\u003cp\u003eA 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.\u003c\/p\u003e\n\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eSKU: OSD-M\u003c\/li\u003e\n\u003cli\u003eCompatible strobe: FOTOCORE GTM\u003c\/li\u003e\n\u003cli\u003eDimensions: 146mm × 36mm\u003c\/li\u003e\n\u003cli\u003eWeight: 422g\u003c\/li\u003e\n\u003cli\u003eAperture modes: 9 adjustable modes\u003c\/li\u003e\n\u003cli\u003eBest working distance: 150–200mm\u003c\/li\u003e\n\u003cli\u003eFeature: lanyard neck for loss prevention\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FOTOCORE","offers":[{"title":"Default Title","offer_id":45141663416435,"sku":"FTC-OSDM","price":285.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0042\/8883\/9795\/files\/OSD-a5dd_c50b6459-00fa-4cfc-9099-08089bd30005.png?v=1782807531","url":"https:\/\/divesea.myshopify.com\/products\/fotocore-osd-m-optical-shaping-device-for-gtm-strobe-1","provider":"Divesea Store","version":"1.0","type":"link"}
