The Bigma was originally released by Sigma in 2001. Over the years, it has gone through several iterations and improvements. This includes the 2006 DG model which is optimized for digital cameras. In 2010, Sigma added built-in optical stabilization (OS) to the Bigma.
gollark: It's not Turing-complete if it has limited memory.
gollark: Not *really*. In languages with an abstract model that doesn't specify limited memory sizes, yes, but PotatOS Assembly Language™'s addresses are 16 bits, so you can't address any more RAM than that.
gollark: Technically it's not even going to be Turing-complete because of the limited address space, unlike in BF.
gollark: I have an amazing FIVE INSTRUCTIONS implemented!
gollark: Soon you'll be able to use PotatOS Assembly Language™ to program things if you don't like Lua.
