Hi Everybody! I got my E-PL1 a couple of weeks ago. I really like it. I've been reading the posts about lenses and I got tempted to get the Panasonic 20mm/f.17. I am totally new to this exchangeable lenses thing, so I would ask for some suggestions. I saw that some people love their 20mm Panny lens and some others enjoy the Oly 17mm. My considerations are: -I would like a small lens to make the E-PL1 small enough to take it with me everywhere. - I love close ups/bokeh - My next purchase will be the underwater case. I am a scuba diver and I will be going to the Great Barrier of Reef for 3 weeks in May. I will need a flexible lens to use underwater (in that regard, the wider angle of the 17mm seems better, right?) This will be my first experience shooting underwater. - I would like a lens that will have good performance in low light. - I am not sure what makes a lens more "flexible", faster speed or wider angle. - I am afraid of a prime lens. Is that to restrictive (I know, I know, I am a totally newbie) I can see that this will be an expensive 4/3 journey. The camera was a gift, but now I am thinking about the lens, the viewfinder (I got used to use the viewfinder with my previous Lumix FZ50) and the underwater case. Oh my! Please, I would love to hear your suggestions. Thanks! Gus P.S. I pressed that damned "buy now" button in Amazon for the 20mm. But I can still cancel or change the order. I am trying to control my buyer's remorse. I apologize if this post should go in another category. I wasn't sure because of the extra questions.
