I just bought a Lumix 12-32 lens for my upcoming OM-D E-M10 body, and I'd like to couple the former with an auto lens cap. Does anyone know if the dedicated JJC ALC-P1232 causes any vignetting? http://www.ebay.es/itm/JJC-Auto-Ope...81?pt=LH_DefaultDomain_15&hash=item5d54d92a2d I also read the "Olympus LC-37C Auto Open Lens Cap" fits the Lumix 12-32, too: 1) http://betterfamilyphotos.blogspot.com.es/2015/03/must-have-lens-cap-for-sony-and-mft.html 2) Reviews in http://www.bhphotovideo.com/c/produ...H5pkCKhm-pN4BOxBsty9I4UGrauPW2aqG4aAorW8P8HAQ 3) I found this interesting YouTube video which seems to feature an Olympus LC-37C lens cap onto the 12-32: Am I right? If all this were true, then the "JJC Z-O14-42 self-retaining auto lens cap", the JJC replacement for the Olympus LC-37C, could be a cheap option for the 12-32. Any advice/help is greatly appreciated.
