With the adapter I am able to use all of my Olympus 4/3 lenes on my OMD 1 and E-m1x. They work just fine. I can't say they are faster but the quality of the lenes looks the same as on my older E5. They are heavier than the newer micro 4/3 lenses, but one hates to toss those older ones just for the weight.
Be aware of your surroundings, ( no ear buds ) etc.. Have your gun at the ready. In otherwords cover your ass. Cops will not protect you. The times, they are changing, like the old song.
I'm afraid you are right. Times have changed since Bob Dylan sang that song. Hate to have to carry but that's the times now. Like the guy in Indiana who shot the shooter in the mall this week, he saved how many lives? A good guy with a gun is the best defense to a bad guy with a gun.
