Intended for H1, H2 with 36 x 24 digital back but unmasked full frame (see below). Excellent condition.
It is the same as the HS-Standard focus screen "Spherical Acute-Matte D type focusing screen with grid and central markings for spot (Ø7.5 mm) and AF metering area" but with the 36 x 24 crop marked as a solid black line.
It's not masked at all so it can also be used like the normal full frame focus screen with (I believe) any H body.
£50 GBP plus shipping.
