Since I personally prefer spot metering, getting the OM-4 was really a no brainer as it provided spot, multispot, hilight, shadows and memory. I use single spot mostly as I know what the latitude is of the films I use.
Then they wrapped it in Titanium and gave it full flash synchronization up to 1/2000 speed but only when using the F280 flash.
I've tested this up to 1/2000 and it works as advertized.
The OM-3 was a gamble as it was listed by KEH "AS-IS, does not work, for parts only" but I bought it anyway and it turned out to be 100% functional and in very good cosmetic condition. I picked it up since I hardly see it and was hoping that whatever ails it that it would be fixable by John Hermanson (
Camtech Photo Services) who I think is the Olympus equivalent to Eric Hendickson.
The OM-3 also has the the same metering and flash as the OM-4 but with a fully manual shutter control.
