So I am thinking I'd like to pick up a longer prime lens for my G5. Currently the longest legacy lens I use is a FD 135mm f3.5, and I have the Panny 45-150. I have invested in a good Canon FD adapter (the Polish one), and I prefer the actual Canon lenses. With the intention of shooting wildlife, the moon, perhaps even the kids from a distance I am trying to decide between a 200mm and a 300mm focal length. My budget won't allow for both yet, and I think the old FD zooms are not as sharp as the primes, plus they are much heavier. Due to budget constraints the two I am considering are the FD 200mm f4 and the 300mm f5.6. Both seem like solid performers for the money, I am just in a quandary over the focal length. So I'd love to hear thoughts, or even sample images. Thanks in advance! Oh, by the way, here's a moon shot from the old FD 135mm f3.5, which on a tripod was much sharper than my Panny 45-150.
