Sorry for the iPhone snapshot, but there are flowers here in Michigan that are actually blooming outside, and I want to get out there.
Here is an idea I found that was a handy way of storing my flat lens adapters that might prove useful to others. I had a lot of CD sleeves laying around and I have always had too many fits trying to find the adapter-of-the-moment I need.
Instead of scores of little fidgety boxes to craw through, I just through them all away (I never sell adapters anyway), and just put the adapters into these CD sleeves instead, arranging them in order. I have two boxes, one for Step-Up rings and another for Step-Down rings.
Not too beautiful, but no one ever comes into my little studio except my wife asking me to vacuum it, etc.
It has already proved very useful, because I am always rigging up one stack of adapters or another.
Just my two cents.
