I have a Contax 90mm Film lens I hardly use. It is quite nice at F2.8 it's really small has a good weight. However, I also have a Zeiss 85mm F1.8 I tend to use a lot more because it is fully automatic and with the Contax I have to do everything (focus and F-stop) manually. 

On the other side, I wanted to try new and different colors in my photos. I usually stick to the same 2-3 filters, but wanted to tweak some more with the colors and add more green and at times red. 

After all, I live in Asia and I wanted the photos to have that feel.
