wow, that must be expensive for the lens,

Still way cheaper than a canon version of this lens.

maybe I should save first to buy this lens hehehe,

Now they have a much newer version with a micro 4/3 camera body that is way better. Very expensive but still cheap compared to the Canon brand version.

I can only dream of this camera, only in my imagination, because my economy is very limited

I would not doubt there is a brand out there that is even more affordable. In the end the light, subject matter and equipment know how matter for a good photo.

it's true, good equipment will produce our work is also good, but an economy that supports it from behind, right or wrong,
