Is the olympus om d e m10 mark ii good for wildlife?
The E-M10 Mark II is a sensible wildlife camera on a budget, mainly because its Micro Four Thirds crop factor of 2.0 doubles the reach of any lens. A 300mm lens frames like 600mm on full frame. It's an entry-level body, so don't expect it to keep up with pro sport shooters, but for birds and animals it does the job.
For reach, I'd look at these on the E-M10 Mark II page:
- OM System M.Zuiko 150-600mm f/5-6.3 IS: the longest reach here, like 300-1200mm.
- Olympus M.Zuiko 150-400mm f/4.5 TC1.25x IS PRO: a faster option, like 300-800mm.
- OM System M.Zuiko 100-400mm f/5-6.3 IS II: a more flexible middle ground.
For the basics of how to approach this kind of shooting, see wildlife and sport.
