Nikon F4/F4s focusing screen, C type (^^) Type: C type (cross-hair type) Although it is unused, it is an old item, so please check the photos before purchasing. Instant purchase is OK ♪ ◾️Product Description◾️ ・Nikon's C-type (cross-hair type) focusing screen features highly accurate focusing with crosshairs, and is suitable for shooting that requires precise focusing (macro, copying, astrophotography, etc.). ◾️From the C-type instruction manual◾️ For microscope and astrophotography. When you don't feel any misalignment between the image and the crosshairs even if you move your eyes slightly left and right, the focus is achieved. However, when using an objective lens of 40x or more with a microscope, this misalignment is difficult to see, so simply make the image and crosshairs appear clear. For F4/F4s, but can also be used with F, F2, and F3 by replacing the frame. -------------------------------------------------- I have a lot of Nikon products on sale, so bulk purchases are welcome ♪ ↓↓ #sara's Nikon product list Nikon Focusing Screen C type for Nikon F4 /F4s 【Top mint】 Includes an instruction manual
