Sling Bag Upgrade

So after trying to fit my insulin kit, iPad and wallet in my small sling bag, I've decided to get something more suitable. Ideally, I want to get a sling bag suitable for holding an iPad, insulin kit, wallet and leatherman. Additionally, I would want have room for my DSLR (with an attached lens), an additional lens and one spare battery.

So far my research has yielded the  following three;

The Kata 3N1-11 has the option of being left or right sling, as well as a backpack and its "X Position" (where the backpack straps cross across the chest). The DSLR compartment is very flexible in its configuration, and can be accessed from both sides. Reviews say that the laptop slot will technically fit an iPad, but that it is very snug. The top compartment is apparently roomy, but I think I would have trouble fitting anything other than my insulin kit.

The Incase DSLR Sling Pack is exactly what it says on the tin. A sling pack for DSLRs. And an iPad or Macbook Air. Only having a right hand sling does seem like a limitation at first, but it does mean the construction would be more solidly built around not having to support inverting it.

With the Enthusiast, it feels like Crumpler built an amazing shoulder strap design, then attached a bag to it. The strap can also be reversed for left or right sholder mounting. The DSLR compartment is very simular to the Kata in its layout and ambidextrous access options.

At the moment, I'm leaning towards either the Incase or the Crumpler, motivated mostly by the thicker shoulder strap. But the Kata does have a more versatile set of strap configuration options.

Camera!

So, I bit the bullet and bought a camera.
I was going to save up for a DSLR, but after talking to some photography friends, they all suggested I get a cheap little point and shoot camera that I can keep in my pocket.
So after a few days of browsing reviews and online catalogues, I decided to buy a Canon IXUS. I had some umart store credit left over from a previous purchase, and that just about covered the cost of a Canon IXUS 85IS.
I have to say, I'm impressed with the camera already. 10Mpx, 3x zoom, macro support. The only drawback, and this is going to sound crazy, its a little too small.

As with any device I purchase, one of the considerations is whether or not it can be improved with third party modifications. In this case, YES!

Many Canon point'n'shoot cameras are supported by the Canon Hackers Development Kit (link). Because the IXUS85 is such a new camera, the firmware is still in beta. Oh well, occasional crashes are a small price to pay for total control over ISO, lens aperture and shutter speed. It also supports a custom remote shutter that plugs into the USB port, helping with making long exposure shots very stable.

Having used it for a while now, I would like there to be a way of running the camera from an external power source (either a bigger battery, or a mains transformer) an to be able to charge the battery from USB.

All in all though, I'm very impressed with both the IXUS85 and CHDK.
