Is the tamron 14 150mm f 3 5 5 8 di iii good for wildlife?
The Tamron 14-150mm gives you real reach for wildlife. On Micro Four Thirds it frames like 28-300mm on full frame, and the focal length guide puts 200mm and beyond in the wildlife range. Be aware of the trade-offs, though. It opens to only f/5.8 at the long end, which makes fast subjects harder in dim light. It isn't stabilised, and it's discontinued, so you'd be buying used.
If you go with it, I'd pair it with a body that's built for moving subjects. From the cameras that take this lens, I'd start with the OM System OM-1 Mark II, the Olympus OM-D E-M1X, or the Panasonic Lumix G9 II.
