I just saw this and wanted to share my perspective, because unfortunately, my experience regarding equipment reliability has been pretty disappointing. I initially chose my current kit based on its supposed durability, but I've encountered several technical issues that really hindered my workflow.

• Mechanical inconsistencies with the aperture control on one of my primary lenses.
• Unexpected electronic failures that required factory service within the first six months.
• Seal integrity issues that allowed dust to enter the internal elements during standard outdoor use. Honestly, I learned the hard way that high-end specifications dont always translate to field reliability. It's been a frustrating process, and I've had to become much more methodical in how I evaluate gear before committing to it for important projects... it's just not as good as I expected for the price.

Below are three highly recommended and best-selling lenses that complement OM-3 effectively:
