I bought this lens hood for my Olympus 45mm f1.8. Yes, there is a little bit of wiggle when attached. I decided to go without the hood so I'm selling it here. If you're looking for a lens hood for your Olympus 45mm f1.8 save a few bucks and buy it from me. It's literally brand new and you won't have to wait 3 weeks for international shipping if you buy it from eBay. Price: SOLD $10 shipped (I will pay the fees). Shipping: US Only. USPS 1st Class Mail. I have not sold on MU-43.com. But, I have sold many lenses on a Canon POTN forum. Check my feedback on POTN (ID: joysmahal).
