Hi Conrad.I did a similar test after work too,however i can go from f5.6 to f 22 and not get the needle(on both K1000's)past middle.Very confusing. Going to keep hand meter in pocket for this work. Could not get them to work on the SP at all. Dave

I used the same spot of sunlit lawn for metering. Setting was 100 ISO. MX with 50mm 1.7 PK-A lens reading was 1/250 @ f5.6 MX with 55mm 1.8 Super Takumar M42 lens was 1/250 @ 5.6 MX with 50mm Meyer Oreston M42 1.8 lens was 1.250 @ 5.6 MX with Tokina preset (!) 105mm lens on PK adaptor reading was 1/250 @ 5.6 So there. The readings are pretty consistent. I can't tell about my K1000 since the meter is no longer able to communicate with me...... Conrad F.
