comment:	This copy looks brand-new. It is larger than the old non-macro Sigma 400mm F5.6 APO or the 300mm F4 APO Tele Macro. The focus grip is much wider than the 300mm lens. "MADE IN JAPAN" The Sony FE 200-600 G OSS is just slightly dimmer wide-open at 400mm. This lens is a bit better aligned than the zoom, but has worse lateral CA. It has a slightly warm color cast.
