I have had a series of Katzeye screens since about 2009 and the only metering issue has been loss of spot metering due to the split image. This is typical for SLRs, you can have one or the other but not both. I did extensive comparative testing of the Katzeye to my K-3's stock screen and found both matrix and center-weighted to be identical between the two. Sometimes I think it would be nice to have spot metering, but given the amount of manual focus glass I use, I will accept the trade-off.
Katzeye is gone now, but focusingscreen.com in Taiwan supplies an impressive variety of screens that fit Pentax cameras, including models for the K-1. Their products are created from commercially available product from Nikon, Canon, and other makers modified to fit our cameras. I was looking their site tonight and noticed that they offer the excellent Nikon K3 screen (think FM3A) for the Pentax MZ-S. That might be a decent combination. We will have to see what they can do for the K-3iii.
