As the title suggests. I’ve been using a self refurbished OM-1 lately and it had been working wonderfully, until I got my latest roll developed, and first roll from this camera. All of my flash pictures came out horribly underexposed. Turns out the FP-X switch was set to FP instead of X, so it was firing the flash as if it was a Focal Plane flash instead of a standard flash. I never noticed since I don’t have any FP flashes all my other cameras are permenantly on X. So either I bumped it when refurbishing the camera or it came that way and I didn’t notice.
Anyway, I did get my Sigma 28-70/2.8 test photos done and a few other good photos on the roll. The Sigma 28-70/2.8 is a pretty decent lens, a bit soft wide open, but nothing horrible and it sharpens up quite a bit when you stop it down.
