Announced back in February 2019, the full-frame Panasonic Lumix S Pro 70-200mm f/4 OIS for L mount cameras is a popular lens. This isn’t much of a surprise, as it’s significantly less expensive than the company’s f/2.8 version. They’re popular rental lenses, too, and the folks at LensRentals have a few of them. In fact, they have a couple of them that seem to have developed an autofocus issue.
So, LensRentals did what LensRentals does and tore it to pieces in order to figure out what’s wrong, fixed it and put it back together. Panasonic doesn’t really offer a repair service for this lens, just an exchange service, which is fine but they don’t want to have the item out of stock for weeks. There’s only one little snag. They’ve never taken this lens apart before. The team documented the complete process on the LensRentals blog, but here are some of the highlights.
