For photographers who want a durable, non-vignetting hood and an included protective cap, this replacement performs the core job well.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect replacement:\u003c\/strong\u003e Replaces the Sigma LH-582-02 hood and fits the Sigma 18-50mm f\/2.8 DC DN lens so photographers can return to reliable flare control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlloy construction:\u003c\/strong\u003e The main body is made of premium aluminium alloy which gives solid impact resistance and a tactile, premium feel compared with plastic-only hoods.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecure bayonet:\u003c\/strong\u003e The bayonet mount is made of synthetic resin to avoid damaging the lens while still providing a firm attachment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-glare finish:\u003c\/strong\u003e A matte interior reduces reflections and helps limit lens flare for cleaner contrast in backlit scenes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter friendly:\u003c\/strong\u003e Leaves access for a 55mm filter so shooters can stack filters or use a polarizer without removing the hood.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtective cap included:\u003c\/strong\u003e The supplied hood cap helps keep dust out and offers extra protection against accidental knocks in a bag.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003ePhotographers who own the Sigma 18-50mm f\/2.8 DC DN lens and need a robust replacement for a lost or damaged hood will find this JJC hood to be a sensible choice.
