My Sigma 70mm Macro inexplicably broke. The images became fuzzy, and the bokeh became slightly distorted.
Disassembling the lens did not reveal any obvious defect. The mechanical complexity of the lens was very impressive, and it explained the price.
The optics looked like they were pressed into their mounts, so fixing any sort of misalignment without special tools was nearly impossible.
There were many screws that were tightened down to the point that I could not unscrew them. I ended up drilling out about 8 screws, and I reached the point of no return early on.
