During the past week, I've been trying out the Grab Focus lens cover for the Oly 45/1.8 lens. It arrived with a professional-looking, illustrated instruction sheet that includes simple instructions for installing and removing the cover, along with a few tips for mounting and dismounting the lens with Grab Focus attached. My first reaction upon holding the cover in my hand, was "Wow, this is really nice!" Even nicer than it looks in the detailed photos Bravin posted in his "Protect Your Lens" thread: https://www.mu-43.com/f38/protect-your-lens-45909/#post447707 The Grab Focus is lightweight and nicely made with a strip of very low-pile, adhesive-backed faux velvet on the inside to assist with grasping the focus ring. The cover slipped easily onto my lens, and I think it looks quite nice on my silver E-PM2 with or without my black hood.

On my first attempt, I used more pressure than necessary, so manual focus was a little jerky. But within a second or two, I knew just how little pressure to apply, and manual focus worked very smoothly. Next up, mounting and dismounting the lens with Grab Focus attached. This test worried me a bit, as my naked 45/1.8 is particularly difficult to mount and dismount. And sadly, despite Bravin's excellent instructions, I've yet to master either task. When mounting the lens (cover installed), the lens sticks about half-way (as it does when naked), at which point I stop, get a better grip on the lens/cover and try to complete the mount. Unfortunately, the cover turns while the lens does not. When dismounting the lens (cover installed), each time I feel like the lens will disengage at any moment. I do manage to move the lens just enough that the camera can't identify the aperture, etc., but the cover continues to turn without the lens. The good news is that I've found I don't have to completely remove the cover to mount or dismount the lens. If I pull the cover forward enough that I can grasp the bare lens base, I can mount and dismount the lens with the Grab Focus on the lens. Further, I don't change lenses much, so even if I had to completely remove the Grab Focus to mount/dismount the lens, it wouldn't be a deal breaker for me. :smile: Even though the faux velvet strip inside the Grab Focus is very low-pile, it does inevitably pick up a little dust. The velvet is so smooth that a quick wipe around the inside of the cover with my index finger easily takes care of it. I really like the Grab Focus. I left it on my lens all week, only removing it for various tests, and I feel my 45/1.8 is well protected from dings and scrapes. My rating: I'll be keeping it on my lens! 4 stars out of 5.
