After I ranted about the bulk and uneven lighting of the K3 + lighted case, I wanted to post some photos of the added weight of the case.
Disclaimer: I don't know if the non-lighted case is any heavier or lighter, I'm just posting my lighted cover weight.
Also, this reinforces my preference of an Octo slip case and reading "naked."
although I do admit the lighted case is kinda growing on me...
