Hi
Thank you for reading my post.
I want to buy a digital camera for around $550 .
right now i have a http://www.benq-eu.com/Products/DigiCam/index.cfm?product=620
benq e600 camera but i want a more professional one.

What do i expect from the camera?

- It should accept a wide range of lens, for example if i buy a lens for it I could use that lens later with newer camera.

- Good for landscape and macro shoot.

- good overall quality.

I want to use it in my trips, daily shoot

Thanks
