One lens' bad fortune is our gain: the Sony FE 70-200mm F2.8 GM's optical test results had been puzzling the team at Lensrentals, and when a customer dropped one recently a teardown was in order. The teardown took a total of six hours – twice the usual amount of time required – and along the way they found a lot of solidly constructed pieces, a mysterious component they dubbed the 'Southern Fairy Tale Ring,' and a great deal of silicone glue.

This article details the first part of the teardown, showing the disassembly of the first half of the lens up to the point where a snack break was needed. It's a long read but as always, thoroughly fascinating and entertaining. It turns out that construction of the FE 70-200mm F2.8 is a bit unconventional, and that's not a bad thing at all.
