One of the reasons why I start packing so early is because I view my gear bag as a jigsaw puzzle. And like all such challenges, they take time to complete.

I'm not sure why I enjoy this activity so much. I view it as my opportunity to defy physics. "Can I pack the perfect bag?" It's like finding the only configuration that accommodates four suitcases squeezed into a car trunk - with success follows a sense of clever accomplishment.

But camera bags are even more thrilling. They're nomadic. Once perfected, they provide the illusion of "I can go anywhere at anytime and do my thing." All I need is this backpack and a place to hang my hat.

There was a missing piece to my current puzzle. I needed a longer lens, but didn't want to lug the 75-300mm for my trek across the country, and ultimately to Havana. Then I found it. The just-released Panasonic 35-100mm f/4-5.6 that's only a few inches long, yet provides an equivalent of 70-200mm zooming range when mounted on my OM-D cameras. I ordered it and am anxiously awaiting its arrival.

I have the perfect spot for it. And it will only add 7 ounces to the weight of the bag.

Will this complete my jigsaw puzzle?

I get excited just thinking about it.
