I found that camera bag.
It's a beautiful, vintage-looking (yet brand new), handmade brown leather bag with hand-sewn removable foam inserts that can be moved around to your liking. This bag is big enough to fit my Canon 60D with 50 mm lens, plus my water bottle, full-sized wallet, change purse, makeup case, sunglasses, phone, and whatever else I feel like throwing in there -- but it's small enough not to be a nuisance. I can carry it around all day as I walk around the city (whether New York or Philly), and it doesn't hurt my little shoulder one bit. And it's so well made. Also, it was $119. That is DAMN cheap for something this amazing.
You might be sitting there a little upset, wishing that you could have had the luck to find this bag. But, you guys, there's more where that came from. Here's THE BAG from LeftoverStudio on Etsy.
I know I'm being incredibly salesly right now. I know it sounds like I'm probably WORKING for this darn guy, but the truth is I just really love this bag. And I want the rest of you to be able to experience the magic of it.
Seriously. Two weeks after ordering this bag, I noticed that it hadn't yet shipped, so I contacted the seller... and he responded with the best answer possible. He explained that he was not getting enough sun due to the cold and fog in Delhi -- yes, Delhi -- and that he needs bright sun to season the bag when he oils it. He gave a few details and then ended on a note that shut me up for good: "I would rather send a bag a couple of days late than send something that is not up to the mark."
I couldn't have agreed more.
