Is the olympus om d e m10 good for beginners?
Yes, the E-M10 family is a good first camera. The Mark IV is the one I'd point most beginners to: it's tiny, stabilised and cheap, especially used. It's a great first camera by my reckoning. The original E-M10 was the first entry-level OM-D, and the Mark II and Mark III are also worth a look.
For lenses, start with an everyday zoom and add a prime later:
- Olympus M.Zuiko 14-42mm f/3.5-5.6 EZ for a light, general-purpose range.
- Olympus M.Zuiko 12-50mm f/3.5-6.3 EZ if you want a little more reach.
- Olympus M.Zuiko 25mm f/1.8 for a natural-looking, low-light prime.
Don't overthink the choice, and buying used can save you a lot.
