For 14-42 Pancake I got myself the 40-150 Zuiko for my Oly OMD-M10. First impression: plastic through and through - but for light, very compact equivalent for a 300 KB, processing consistently good. Unlike the Sigma E-mount 30mm for Sony Nexen rattles here not UDN rustling nothing. First impression after a few photos so: The OMD-M10 is a fast camera both in terms of AF as well as image sequences. The 40-150 brakes Camera nhicht, it focuses very quickly and accurately. The image quality is consistently good, the price of 150 almost sensational. Open aperture in portrait going quite well to 1-2 stages dimmed the Objhektiv is nice and sharp, the stability of the M10 comes with the loose, even in low light. Just travel the combo with the handy M10 and the Pancake and the telephoto zoom 40-150 is really great, I'm ready for anything at ca 600 gr total weight. And when the lens several times what was gotten or bitches makes: for 150 I'll get like another new. Can highly recommend the lens for all Olys m4 / 3, since not stabilized for the Panasonic G's less,
