Panasonic LUMIX G 42.5mm f/1.7 Aspherical Lens for Micro Four Thirds, Bundle with 37mm UV Filter, Flex Lens Shade, Lens Wrap, Cleaning Kit, Lens Cap Tether

I have been using the Oly OmdEM5 for about a year, satisfied with the focusing but had thought that throwing a background out of focus was not attainable with M4/3. I decided to try the Panasonic 42.5 mm lens. It has enough reach and wide enough aperture to make creative use of depth of field. I am very impressed with the sharpness of the lens that I got, also I appreciate getting a lens hood and bag with the lens. Took photos at an xmas party just casual get in here and lets get a snap, the oly face and eye detection is superb with this lens and I fooled around with aperatures from 1.7 to f4 with a big group that might have faces in different planes. Never missed getting what was important into focus and could throw the background out. Found the out of focus areas pleasing to my eye. I was using the little camera flash and a slave bounced from the ceilings and it all worked well but took a bit of set up before bringing the partiers into the shooting area.Things I like about this lens: 1. close focus to .31 meter2. included lens hood and storage bag3 seems to be flare resistant4.sharp across the frame5 silent focus6 internal focusing7, metal lens mount that does not grind when attachingDislikes so far and I have just started with it.1 nothing It has some plastic in construction but is lightweight and appears to exhibit quality construction.2 my camera cannot take advantage of OIS in lens and body it is either or, Oly 5 axis works great so that is just a nit pic.
