Nikon F4/F4s focusing screen, C type (^^) Type: C type (crosshair) Although it is unused, it is an old item, so please check the photos before purchasing. Instant purchase OK! ◾️Product Description◾️ ・Nikon's C-type (crosshair) focusing screen features high-precision focusing with crosshairs, making it 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 slightly move your eyes 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 many Nikon products for sale, bulk purchases are welcome! ↓↓ #sara's Nikon product list Nikon Focusing Screen C type for Nikon F4 /F4s 【Top mint】 Includes an instruction manual
