So I've been using my 40D for a few years now.. won some photography competitions locally and magazine competitions internationally, changed a few lenses, and broke the shutter once.
Finally, I'm down to 40D + Sigma 30mm f/1.4 at the moment and I am looking to upgrade. I've always been attached to still life photography which is also the genre of photography competition that I usually have some achievements. I am looking to invest into a new body (possibly 7d because 5dm2 is slightly stretching the budget and the fact that I have a Sigma 30mm f/1.4) and my first flash gun (possibly a 430ex II or maybe 2 YongNuo?) or maybe a new lens? I will be turning one of my rooms in the house into my mini studio so I'll invest into some tripods for the camera and flash, umbrella?, what else do I need? This is because recently, I am interested to try some strobist thingy as well.
I have budget of 1.5-1.6k to spend. I can get 7d from grey importer for around 1.2-1.3k and 430ex II at $260-280+..
