It finally clicked for me why some shutter fixes fall apart
I've been fixing cameras for years, and shutter timing on old models always gave me trouble. Last week, I had a Nikon F2 on my bench with a shutter that was not right. I cleaned every part, adjusted the curtains, but it still acted weird. Then, I looked close at the tension springs and saw they had a bit of corrosion. It hit me that corrosion, not just wear, causes many of my past fails. I swapped the springs, and now the shutter runs fine. I feel dumb for not spotting this sooner. Do you guys check springs for corrosion as a normal step?
