Hi all, This is my first post on Mu-43. I've been reading it for the past few days and it looks like a great site with lots of knowledgeable members, so I'm hoping I can get some advice. I'm what I would call an advanced amateur photographer currently shooting with a Canon 5D II and 7D with an assortment of Canon L glass, a Zeiss 35 f2.0 and the Sigma 50 and 85 f1.4. Great stuff most of the time but there are occasions when I don't want to carry the weight and be the object of sometimes unwanted attention. So, I'm thinking of getting a micro four thirds system for travel, street photography and just those times when I don't want to lug around my 5D II and a bag of lenses. I'm not as young as I once was and this stuff seems to be getting heavier every year! I have a Canon S90 and if the light is just right, it can produce pretty good images but overall, I find it lacking in image quality and using it is frustrating compared to a dSLR. I'm hoping that micro four thirds will be the answer, i.e. a much smaller, lighter, unobtrusive system that is responsive to use and will produce great image quality, albeit not as good as I currently get from the 5D II. To that end, I'm considering the new Olympus E-P3 plus two or three lenses. Firstly, is the E-P3 going to meet my expectations and secondly, what lenses should I get? I'm thinking I'd like to stick to fast primes but the E-P3 seems to come with either a 14-42 slow zoom or a 17mm 2.8 which doesn't seem to be well thought of and isn't very fast. So, if I must choose one which one? I'm leaning to the zoom at the moment. After that, I'm thinking of the Olympus 45mm 1.8 and possibly the Panasonic/Leica 25mm 1.4 for a good and fast 50mm equivalent. Or is the Panny 20mm 1.7 just as good, as well as both smaller and less expensive? I'd probably want to add something wider eventually but I understand that both Zeiss and Sigma will be producing four thirds lenses and may wait until they do. Lastly, is the external viewfinder a good idea? The S90 is the only camera I've ever had without an optical viewfinder and I find it difficult to compose images that way. Any and all advice will be most welcome and sorry for the long first post.
