3M-6A 500mm f/6.3

(1 customer review)

The 3M-6A 500mm f/6.3 is a type of camera glass that allows for super telephoto shots. It is manually focused and has no aperture control function, meaning it always works wide open. The lens is quite large, measuring 163mm in length and weighing 1400 grams, so it may require its own bag for transportation. It has a 95mm lens filter diameter, which can be expensive to purchase, but the Cokin system may be a more affordable alternative. The lens is made up of multiple elements and has a lens coating to improve image quality. The manufacturing time is unknown. The aperture is fixed at f/6.3. The build quality is sturdy and durable. The resolution of the lens is not specified.
