Wow, it has been a long time since I have participated here! That needs to change. I love this forum. Here's my question: What do you think about using the M43 system for professional wedding stills (not video)? Now, before I get caught in a flame war about clients deserving "the best" and "M43 is not up to it" yada yada, let me frame my question a little more. Professional, creative photography is - I think we can all agree - more about the photographer who creates the image than the equipment. Not that good equipment doesn't help. That said, the camera, and sometimes are particular camera, is often an extension of a photographers technique and style. I have found, shooting weddings with Canon equipment (40D / 7D) that I just don't shoot as comfortably and freely - nor do I enjoy myself as much - as when I'm shooting my little GF1. For me and my style, being comfortable, free to move, and enjoying myself is critical to my creative thinking and execution process. For portrait sessions it's not as big of a deal but for weddings and events, I prefer to be a little more incognito shooting photojournalism style / creative pose expressions. I cannot help but wonder if I would do better and be more creative using M43 gear. Drawbacks? Certainly. First and foremost, the question of digital noise comes up. No doubt there are some fast lenses available, 12 f/2, 20 f/1.7, etc but even then - with a wedding - I'm in some real low light situations. The ISO is going to get cranked up. Can the M43 systems handle it? My thoughts are that it really depends on what you as the photographer like creatively as opposed to the client getting the "absolute best" etc. I actually like and find usable the ISO3200 shots I get out of my Panny when properly exposed. I'm willing to bet that the newer M43 cameras are even better. I think of Riccis Valladares who shoots Leica film equipment. Few could argue his photography is anything short of beautiful, but it's all shot on film which handles noise/grain even worse than M43. But his style works because he works the grain into the finished work and using the smaller cameras free him up to work the way he likes. With my Panny, the only issues I have at ISO1600 and 3200 are chroma noise which I can easily fix in LR. My only other issue would be flash lighting which I use from time to time. Is there a comparable flash I could use on a G3 for example to the 580EX? Bounce , swivel, decent power, etc. Also, would my Elinchrom Skyports work Ok across the M43 spectrum? I use those to fire off camera flashes during portraits / reception dancing. I haven't yet tried on my Panny, though I'm gonna give that a shot next time I have them out. Finally, the kit I would probably use would be the Panasonic G3 (I think that's the highest end one now) since I need a nice viewfinder, and my GF1 w/ LVF1. The G3 would come in handy because I could use the viewfinder and still have a hot shoe available for transmitting / using on board flash. I might even use two G3's. My lens kit would likely be the Oly 12mm f/2, Panny 20mm f/1.7, and a 45mm f/1.8. That would do nicely for me. I like working with primes and there's really no fast zooms available. I might also try the new Leica 25mm f/1.4. So... thoughts?
