So, I live in the city of St. Louis. I managed to find a bald eagle in one of our many city parks (yea I know, a bald eagle in the middle of the city). I brought my E-510 and kit lens with me when I went looking for him once I heard about him, but had no luck of any photos of him. Some great visuals, but I couldn't capture him). My question is, what is a good length of lens to use to capture him? I'm going to rent a lens (all I have is the kit lens) and go back and see if I can get some good shots. It's a small park, and when I saw him flying, he was at the closest 30 yards away and at the farthest 150 yards. Is a 200mm good enough or do I need a 300mm? I'm wanting to eventually buy this lens: LensRentals.com - Rent a Olympus 70-300mm f/4-5.6 But I'm curious about this one as well, but don't think I can afford actually buying it. What do you guys think would be better to use? LensRentals.com - Rent a Olympus 50-200mm f/2.8-3.5 SWD Yes, I know these are rentals, I think the 70-300 is better for my situation, because it's a more affordable lens and it's something I'm wanting to buy. So renting it now will be useful to decide if it's something I want right now. But I feel like the other is a much better piece of glass, based on the price for renting it at least. So what do you think? Also, any tips on how to get some good shots of these guys are much appreciated. I'm new to birds, and photography in general. But I think this is something I could get into. I got really excited when I found him and saw him flying, but who wouldn't...it was a bald eagle. So I think birds are going to be my new thing.
