If I mess up or change my mind later a bit of heat gun action makes it soft enough for disassembly and removal. I have even done it on plastic bodied lenses (Pentax-110) and while machining and screws are way more elegant, the results are the same: lens focuses 100%<br />I do prefer to make my own extension tubes/adapters for most lenses even if one is available commercially as dimensions are often wrong on the commercial ones anyway.gnarlydoghttps://www.blogger.com/profile/02783031534973509076noreply@blogger.comtag:blogger.com,1999:blog-4577546745078520453.post-59638332920809370042016-07-01T04:28:28.032-04:002016-07-01T04:28:28.032-04:00it looks remarkably like the Olympus 45mmit looks remarkably like the Olympus 45mmobakesanhttps://www.blogger.com/profile/13743339737847465926noreply@blogger.com
