AstrHori 28mm F13 2X Micro Probe Lens

AstrHori Prob Lens 

• 2x Magnification: The Unique AstrHori 28mm F13 macro probe lens design offers a greater-sized 2:1 maximum magnification along with a minimum focusing distance of 0.48m. The long probe lens barrel can produce a bug-eye perspective and, even with the short working distance, the length of the lens barrel places the camera at a comfortable shooting distance.
• 75° Wide-angle of view, 28mm focal length: Affords greater depth of field and more surrounding detail than traditional macro lenses.
• Slim front diameter, built-in LED ring: The slim front diameter allows for "slide-in" shots and affords a greater range of close-up shooting. The smaller front diameter is equipped with a built-in LED ring that also makes it easier to illuminate close-up subjects from the front. The LED can be powered by the USB port on the lens barrel.
• Waterproof Design: The front of the lens is waterproof, allowing you to comfortably work just under the water surface or in dusty environments. (the front of the lens waterproof working length is 25cm)
