Universal 1° Spot Meter comparison test
A Comparison table for old and
new (35mm, D-Slr, Medium Format)
Spot Metering / Partial Metering cameras
based on 1° (degree) spot angle (acceptance) to match
the
Spot Metering power of the Pentax Digital / Analog (Standard) 1° Spot meter
Please e-mail me any errors/mistakes on this site or
this table. I will be thankful.

How
the On-Camera Spot Meters are rated
(please
note: If what
you see here does not please you,
you can change the
rules and produce the results that make you happy!)
1)
Start with 10 stars: **********
2) Subtract 3 *** for the lack of a distinct spot frame in the viewfinder.
Please note: Accuracy demands a distinct frame for measuring
small areas.
3) Subtract 1 * if less than 100% of the spot angle
(Sensitivity /
Acceptance) is measured
4) Take away stars depending on the size of the spot angle with a normal
lens using the following criteria:
9° or more subtract 5 stars *****
8° to 8.99° subtract 4 stars ****
7° to 7.99° subtract 3 stars ***
6° to 6.99° subtract 2 stars **
5° to 5.99° subtract 1 star *
0° to 4.99° subtract 0 star
Table
sorted by the mm of the lens to
reduce the spot angle of the camera to 1º (degree)
