In reply to What Goes Up:
> (In reply to beneboy) I had the good fortune to play (albeit briefly) with the new Olympus OM D last weekend, and if you're into your cameras enough to have a 5Dii and L lenses then I would suggest this would be a real contender (if you can get your hands on one quick enough). Slap a pancake lens on it and it's practically a compact, image quality is superb and if you do get one I'll have very green eyes.
I have an Olympus E-PM1 with three lenses
- Panasonic 20mm/1.7
- Olympus 9-18mm
- Olympus 14-150mm
It's truly a spectacular camera regarding portability. Most often I have the 20mm lens on it and the picture quality is truly superb. The zoom lenses have some problems with blurry images, low light and CA. I think most people won't notice it at all but once you've used the fixed 20mm lens the difference is clear.
The pros:
+ light weight
+ low bulk
+ superb image quality with fixed lenses
+ nice bokeh effect with the 20mm/1.7
+ sharp hand held fotos in low light with the 20mm/1.7
+ because of the size I carry it on me almost 24/7
The cons:
- pictures with the zooms could have better image quality
- the zooms could have better build quality
- CPL filter is impossible to use in bright light
- I cant't see the screen in bright light
How to fix the cons:
* Buy an OMD EM5 (1000€)
-> two more stops better sensor (fixes some of the image quality issues of the zooms)
-> the view finder fixes the issues with CPL and screen
* Buy 12mm/2.0 (650€) + 45mm/1.8 (280€) + 150mm/2.0 (available in 2013)
-> no need for zooms
If I had the money an OMD with the fixed lenses would be it. I would really recommend the m4/3 system for someone with experience of advanced cameras and high quality lenses.
