Today I went to the Beijing Olympic Park to take photos for Storm Trooper and Cyberman.
The camera used today is Pentax KX. The lens is Sigma 28-80mm f/3.5-5.6 Marco version. Both of them are extremely cheap. A Pentax KX camera without kit lens can be bought with even less than 100$, and the Sigma 2880 is even much cheaper than this camera body.
Firstly, I took the shots with different setting lights.
Then I took some photos with my cellphone.
