Olympus 150mm f/2 ED Lens Strap Tips?

I use a Black Rapid strap which attached to the tripod thread. So you can attach it to the foot on your lens. If you use an Arca plate on your lens foot, simply add a simple clamp to your strap and clamp it onto the plate.

 

If I use a strap at all I use a Black Rapid like @bassman. But I hardly ever use a strap, I mostly carry the camera/lens around by the tripod foot. To me, straps just get in the way, especially when trying to crawl closer to an alligator. The only time I use my Black Rapid is when I am shooting sports or the airshow, mostly because I have a 2nd camera with a different focal length with me (I have the Black Rapid strap designed to carry two cameras or can convert to carry one).

 

I also use Black Rapid plus quick release clamp when I'm not crawling around alligators.

 

Then you get eaten by a gator because that lose strap got caught on a stick when you were trying to get away quickly

 

The Black Rapid is a great system and should be what you are looking for. You can also use it like hunters use a sling to wrap around their arm and get a steadier shot.

 

On my 40-150 f2.8 I keep a Peak Design Arca plate attached to the tripod foot. This also has an Anchor attached to it. When I need to carry the camera and lens, I use a Slide attached to the tripod foot, and an Arca plate w/ Anchor attached to the camera tripod mount. I have never seen a 150 f/2, so I'm not sure how the 2 compare in size.

 

I use an OpTech Lens Loop clipped to an OpTech Utility Sling (like a Black Rapid) with the 50-200 SWD on my EM1. Takes the strain off the camera strap lugs and distributes it around the lens mount. Off my neck too. Hangs next to my side a lot better than if I attached a strap to the tripod foot, and stays out of the way when I'm using the camera. I can use it even if I take off the tripod foot. Found this when I was looking for a way to carry a big lens safely. OP/TECH USA Lens Loops System Connector
