Loose Lens with Olympus OM to Canon EF Adapter?
Recently, I bought two manual focus Olympus OM lenses on eBay, the 50mm f/1.8 and 28mm f/3.5. Nothing spectacular, but I was impressed with the optical quality, and solid build of these lenses, they’re just good bang for the buck. Yes, the Olympus OM 50mm f/1.8 is perhaps even better than the Canon 50mm f/1.8!
The day after, I ordered some OM to EF mount adapters with focus confirmation from BIG_IS. The focus confirmation works fine, however, I noticed that when I attached the lens to the adapter, the lens was slightly loose on the adapter and could move around a bit while focusing.
I contacted the seller about it and learned this little hack: There are three small grooves on the adapter’s mount, if you use a tiny screwdriver to widen these grooves just a little bit, the OM lens will fit the adapter more tightly. Be careful though, don’t widen them too much or it’ll be very hard to dismount the lens from the adapter again. See the image below, it works!
