Thanks for all the comments.
Regarding the use of an M9 for landscape shooting, here are my thoughts...
The M system (M9 in particular) has some advantages and disadvantages for landscape shooting.
- 18 MP finally gives enough resolution for large prints with maximum detail
- WATE is a superb landscape lens
- Compactness and light weight of M9 kit allows me to hike/walk for miles to get shots that I would not get with my heavy DSLR system (I simply wouldn't lug all the weight across long distances on foot)
- Superb prime lenses give fantastic image quality without concern for muddy/soft corners, CA, etc.
- No "live-view". This is huge. With my 5D II, I can set up the shot, then zoom in at 10x on live view to nail the focus with manual focus adjustments. No way to do this on the M9. Just this one feature alone would make the M9 a significantly more powerful landscape camera
- No lenses beyond 135mm, and even at 135mm, the lenses are often miscalibrated. I often shoot landscape shots between 100-200mm on my Canon system. On the M9, the 90 APO is the longest lens that I really "trust". The 135 APO is good, but is very hard to calibrate for accurate focus, so anything other than infinity focus makes me nervous.
The M9 is significantly better than the M8 for landscape shooting for a few reasons. The biggest are:
- 18MP vs 10MP (this really matters in fine-art landscape large prints)
- Exposure bracketing
- Uncompressed DNG (I haven't analyzed the impact, but want every ounce of IQ)
For this trip, I brought my 5DII along with the M9. The 5DII never even made it out of the camera bag. The M9 is the best set of compromises / trade-offs for my needs. Just wish they'd add the live-view (I know they can't do this on the current sensor), and then it would be even better.
