Pros
M2
1. UNGODLY IMAGE
2. UNGODLY LOW LIGHT
3. You'll get more freelance work from it
4. Shoots great photos, also freelance opportunity
5. Good codec for video that cuts well on most computers (my intel iMac cuts it without much hassle)
6. Now has manual controls
Huh? Those don't sound like actual, plausible facts. Is anyone really cutting the 1080/30 from an MKii directly? My Desktop is pretty beast and it still won't chop it without hiccups.
Pentax K7 (don't giggle please)
1. BUILT IN IS for the sensor, you can attach ANY LENS and not worry about jitters
2. Lenses are cheaper due to built in IS you can hit the ground running and be able to afford a full lens kit for anything you can think of.
3. Pentax has a HUGE selection of PHENOMINAL lenses...does Canon have a telephoto macro lens with IS? Or a first party wide angle lens that can focus a mere few inches from the lens? You can use film lenses and have the electronics still work on the K7.
1. Do you know if that has any adverse effect on video? Anyone tested yet? I'd like to see if it corrupts image in any way (ghosting, degradation, etc).
2 and 3. Lenses are as much as you want to pay for them. The MKii isn't limited to Canon glass nor are the K7 or GH-1 limited to their respective manufactrurers glass.
CONS
M2
3. Not a great selection of pro grade telephoto lenses with IS (just the 70-200mm, which is a big dent in the wallet)
5. If you want a backup body, Canon seems to be crippling their prosumer/consumer cameras, so you're forced to shell out for another M2 (hopefully the 60D has manual controls)
3. There's an excellent selection of glass that ranks pretty high. The selection doesn't get smaller just because someone can't or will not pay for them. It's Canon...
5. I'm not sure if that's a factworthy con?
GH1
1. Really limited lens selection - not keen on paying $1000 bucks for Panasonic's 4.0 aperture lenses. And if you want a fast telephoto lens with IS , you're screwed and have to wait IF AND WHEN panasonic released one.
3. AVCHD is a ***** to edit
1. Limited lens selection? The camera can take PL mount lenses... if for some reason you're actually only considering auto lenses then sure. Most of us, MKii or Gh-1, aren't using auto lenses. My entire Contax Zeiss collection works with the MKii and the GH-1... I'd hardly call it limited. That might need to be changed to "Panasonic doesn't make a lot of lenses but you can adapt just about any glass to the GH-1"
3. Not really. Premiere cuts natively, you can port to ProRes with FCP.
If I'm missing something let me know, but that's my take. I really want 2K7 bodies and a GH1. I'd love a mark 2 but don't think I can afford it and it's astronomical lens cost. I really get way more exciting looking at all the Pentax Glass available.
If you're only looking to match camera manufacturer and their glass then the cost of Canon glass can be called astronomical. Otherwise, the GH-1 and Mark II can and will take loads of different glass, with the GH-1 taking more than the MKii.
