Hello everybody,
In recent years with APS-C bodies (K7 - K3) I used an split image screen from focusscreen.com actually a Nikon K3 screen sized back to APS-C
But for the K1 nothing is available yet.
The screens of the K1 are replaceable similar to the APS-C series.
The Pentax's screen is really large 26mm x 38.25mm so my "raw" material needs to be as large as possible
the best candidate are the screens for the Canon 1D series.
I ordered a original Canon Ec-B screen (quiet affordable) and did a small modification, see the pictures below for a small tutorial.
UPDATE:
After some days of use I discovered that the focussing was not correct, (front focus) this was caused by a too small distance between lens and screen, hence I had to bring the screen a little up. In the body is a brass shim (metal frame) which can be removed too, one can replace this with a thinner one, or as I did, grind it back to the desired thickness.
However it is important that the thickness is uniform across the frame, in order to do so I glued it on a flat piece of wood and then gently grind it back. see the last picture.
The brass shim is just visible, totally on top of the picture with the K1 Body, Releasing the shim is done with the most right side release.
The focus conformation of the AF now matches the screen.
Second update I changed the splitscreen for a microprisma screen that serve my needs better. (Canon Ec-A)
This set up is now used for a couple of shoots and I am 100% happy with it.
Disclaimer: modifications are at your own risk.
Happy snapping Gert Jan
