Gear dilemma time.
I've had my Canon 30D for nearly 10 years now. Loved it - and still do. Have built up a good collection of lenses too, all of which I enjoy using in quite different circumstances.
10-20mm:


24-105mm:


100mm macro:


70-200mm:


The problem is, together, it's all enormous. So big that in recent years I haven't actually really taken it anywhere, which is obviously a complete waste.
So I want to downsize to something more portable. I don't want to compromise on features too much however.
Musts:
- Manual control of aperture is mandatory
- Low-light performance no worse than 30D
- Decent AF - preferably with back button focus functionality or similar
- RAW
Can compromise on (all focal lengths are 35mm equivalent):
- Interchangable lenses is OK - but max of two.
- Probably don't need 320mm (35mm equivalent) - shoot at this focal length quite infrequently. Would want at least ~160mm at top end.
- Probably don't need to get down to 16mm either. ~18mm would be OK.
- 1:1 macro isn't really needed either. As close as possible would be nice, but again I do this fairly infrequently.
Considering selling all my Canon stuff and getting an Olympus OM-D E-M5 II with a M.ZUIKO DIGITAL ED 12‑40mm 1:2.8 PRO and maybe a M.ZUIKO DIGITAL ED 40‑150mm 1:4.0‑5.6 R.
Alternately, sell everything except my 24-105, and get a 6D.
Other suggestions?
