Checking your photo composition, focus or histogram outdoors is easy with a HoodLoupe from Hoodman. HoodLoupe is worn around your neck. To review camera images glare-free, place HoodLoupe over your camera’s LCD. HoodLoupe’s /- 3 diopter adjustment accommodates those with less than perfect vision; turn the eyepiece in or out to set for your vision. Precise glass optics give you a bright, clear and non-pixelated image to view. The optical module accepts multiple sizes of mounting bases. The H32MB model comes with the correct base for up to 3.2 inch LCD screens. Should your LCD size change, you just need to buy the HoodLoupe base that fits your new LCD size. To save space, the optical module separates from the base, which will nest over the optical module and fit snuggly in its carry bag. HoodLoupe integrates with all Hoodman live view mounting plates for hands-free use. The neck lanyard provided can be upgraded to a retractable lanyard that clips to your belt.
