My wife recently determined that a large DSL was not on the cards due to the size (yes she is the boss) anyhow I convinced her of getting an E-P3 as I wanted a camera with inter-changable lenses. I enjoy surfing and wanted to start capturing family and friends on the above system. I know the system isn't the best for this type of photography but thought I'd give it a go anyway. I have been researching various options and wanted to know of anyones experience with the following setups and/or peoples opinions/recommendations. I was thinking of one of the following: m.zuiko 75-300 zuiko 70-300 (with adapter) Oly 50-200 (with adapter) Panasonic Micro 4/3 100-300. I'd imagine the natives would have the fastest AF but are the 4/3 lenses that much slower? Also has anyone used the 50-200 on a E-P3? I only looked at this lens for its f2.8-3.5 how good would it perform in lower light conditions such as an overcast day or would one of the above lenses still yield acceptable results? Thanks for your help in advance.
