Just to remind myself and to prevent impulsive splurges, this is my photography wish list, in order of importance/urgency/necessity:

1. Canon Speedlite 580EX II
As Helmi advised, if I own my own 580EX I can learn and experiment with flash photography. I may have a 320EX but it lacks manual control, master mode and less power. Using a 580EX for Ezza's photo booth was a good experience which I hope to have more of.

2. Tokina 11-16mm f/2.8
I used this glass for Hari Raya and utterly enjoyed it. Looking at e lenses I currently own, this SWA lens will be a good addition which should/will last a long time.

3. Wireless flash triggers
With 2 speedlights in my collection, having a wireless flash trigger system will be an excellent option, giving me more flexibility and creativity. If budget is not an issue, PocketWizard would be ideal.

4. A standard zoom lens to replace my kit *or* Canon EOS M *or* Fujifilm x10
If I ever reach number 4, I will probably have to re-evaluate this list again. I am interested in owning a mirrorless camera but whether it is the EOS M or its successor I will have to wait and see. Or a replacement lens for my kit which I don't use that often. The thing is, by the time I reach this point I would have a Wide angle lens, a telephoto, a standard kit and a nifty fifty. Shouldn't that be sufficient for an enthusiast like me? So by this stage I will have to relook at my photography and see where I want to move forward. Although at the time of this posting I am deeply interested with the X10 as a travel and alternative camera. It will depend on how much the EOS M will cost and its reviews.
