Disparate images I know, but these were shot with an Olympus M5 Mkii with the Zuiko Super Wave Drive 12-60mm F2.8,
which is a Four Thirds system lens on a Micro Four Thirds camera body using the Olympus MMF-3 lens converter.
The MMF-3 cost a mere 175.00AUD, whereas the Olympus 12-40mm F2.8 pro lens costs around 1200.00AUD.
Since focusing more on birds I seldom shoot wide angle nowadays, so I think I've made a good investment.
Notably, the SWD 12-60mm isn't listed in this site's Olympus gear, along with a lot of other Oly stuff.
