I've been reading about how great this lens is and how it's a must have micro 4/3s. Problem is I've come from a point and shoot background, one with 12x zoom no less, so I'm pretty used to using zoom. When I first found out about prime lens, and how it can't zoom, I was so shocked. lol. I just don't know how to cope! I could carry more lens of cause, but for this instance, lets say I only had the panny 20mm lens. I was wondering if this was possible. Say I was taking a vertical picture of Eiffel tower from afar, where the tower only filled up half the height of the frame due to the distance. Could I then go home, use post editing to crop out just the Eiffel tower, and then enlarge it to fit in a 4x6 photo, thereby achieving a picture that I would've have taken if I had zoom? This question is most probably really silly and obvious, so sorry in advance =p If possible, how much can you enlarge a 12mp picture before it starts degrading?? I usually print 4 x 6s. Many thanks!
