Is the om system om 1 mark ii good for wildlife?
Yes, the OM-1 Mark II is one of my wildlife favourites. It has a stacked sensor, very good bird detection and a light kit, which matters when you're carrying a long lens all day.
The lens does most of the work for wildlife, though. For reach, I'd look at:
- OM System M.Zuiko 150-600mm f/5-6.3 IS, like 300-1200mm on full frame, for the longest reach.
- Olympus M.Zuiko 150-400mm f/4.5 TC1.25x IS PRO, a brighter option when light is short.
- OM System M.Zuiko 100-400mm f/5-6.3 IS II, a more manageable middle ground.
