Hello - Seeking some feedback on which telephoto zoom to pair with my new GX8. I would like to take advantage of the Dual IS and fast focus ability of the body. I don't currently use a telephoto all that often but I would like to have one in the kit. Size/weight is a motivator as well. I think I am debating between the 35-100 f4-5.6, 45-150 f4-5.6, or the 45-175 f4-5.6. From what I have read from some older threads the 45-175 seems to be perhaps marginally sharper than the other option and better for video, which honestly isn't too much of a factor most likely, although I am not too sure what will come in the future as the kids get older. The 35-100 has some real appeal as well considering the size/weight, which will mean that I will likely carry it more and therefore use it more... so that is a real plus. But the PZ is presumably faster at comparable FL and has more reach obviously. Plus if it is sharper... By the way, are any of these particularly more or less prone to shutter shock? Anyway, curious about some feedback on the various choices. Many thanks!
