In the future I might buy the 60mm or a legacy macro but for now I'm looking for a lightweight macro converter for the Oly 40-150 which I can throw in the pocket of my bag. I'll be getting the 45 f1.8 soon and it'd be nice if the adapter would fit that as well. I have the Oly 14-42 which focuses closer, but isn't zoomed in as far as the 40-150. I don't like this lens, but on the Olympus MCON-P01 page it shows that this lens would focus closer, nearly negating the fact that 40-150 is a much longer focal length. This guy shows that the bare 14-42 renders the 40-150 + MCON-P01 useless for macro. Yeah? This MCON-P01 would fit all my lenses, however and the Olympus page clearly shows specs regarding how narrow my focusing distances will be (at max zoom, I'm assuming?), but I'm not so sure about A) the quality of the glass? and B) if I can focus closer with other brand adapters? When lens specs say "minimum focus" for a zoom lens, do they mean at the widest focal distance? Next, there are the Marumi screw-in filter macro converters. So, I'd have to get the 58mm one to fit the 40-150's threads. Are there adapters that would work to use to get the 58mm one on the lenses with the smaller threads, or would that put the filter too far away from the len's outer glass? Also, what the difference between a 330 +3 and a 200 +5? They must mean 3.3x and 2x magnification, I'm assuming, but what's the +3? And what will my focus range be with each on the 40-150 at various zoom steps? And what is this? Finally, there's the 1.5x Raynox 150 or the 2.5x Raynox 250. How's the glass quality vs the Marumi? And what would be my focusing distances? Uggh. Sorry for all the questions!
