Lenses: Four thirds 40-150mm f3.5-4.5 Micro four thirds 40-150mm f4.0-5.6 I'm looking to add a few lenses to my bleak OM-D system, I currently only have a legacy Fujinon 55mm and the 12-50mm kit lens, I'm looking to grab the 45mm f1.8 at some point, along with a wide'ish pancake (12mm f2.0 Zuiko is too expensive!) and telephoto lens, I thought I'd start with varying my focal length and go for the telephoto first which should completely cover my range, then I can get into different apertures once I can afford them. My budget is £110 and I've found a few in that range, I'm mainly looking at the 40-150mm Olympus lenses, the old 4/3 lens and the newer m4/3 lens, but I cannot choose between them, the older one would need an adapter but that remains in my budget (£70 for the lens, £40 for the adapter) just fine, where as the newer, slower one is £105 used. My preferences are aperture and image quality, the old one has a bigger aperture (f3.5-4.5) than the newer one (f4.0-5.6) which is already a good start, however I'm mostly worried about the image quality being worse, with it being an older 4/3 lens. Size isn't much of an issuel, going by dimensions they're both fairly close (older being a bit bigger) and would both fit nicely in my camera bag and wouldn't be much of an issue, I also wanted to know if either of the lenses supported the OM-Ds IBIS for video, which would be a nice bonus if a zoom video is required. Thankyou for any replies, all the best.
