Hello, How are you? I'm searching for a tele-zoom for my m43 kit. The main goal is to do a bit of plane spotting. The secondary goals is to do some bit of wildlife shooting, bird watching, a bit of motorsports and all that... I have my eye set on the Panasonic 100-300. But I am afraid that for somethings, especially the plane spotting, the 100mm might be too much... So today I went to the airport with me E-PL2 and kit lens and took some pictures with the lens at 42mm. These are the results: These images are straight out of the camera with no cropping and no editing what so ever. Not t very good or artistic images, but just for illustration purposes. On the last two images, I think the 100-300 would do a great job, when the planes are taking of from that runway in that direction. But when their are accelerating down the runway, I think the 100mm might be too much and I might not get the whole plane on the frame... On the other end, would the 200mm of the 45-200 be enough when the plane is already in the air? I know that for the rest of my purposes, mainly wildlife and birds, the 100-300 would be better for the extra reach, but could I do it good enough with the 45-200? Hope to hear from you! Cheers!
