Flash gives you more control and is usually much more powerful as concentrated light sources than your average incandescent source.
You can get very decent setups with Yongnuo clone speedlites and cheap accessories. Portable too
Granite can be cheap, hard to scratch but also very heavy, can crack, give you a bad cut if edges are not treated and in general a pain to handle etc. Also it usually has some grain that might not be homogenous/desirable.
Hunt for acrylic sheets online, or ask a local signage guy for their supplier information or any cheap leftovers (why not freebies?).
I get them from local plastics warehouse in far east LA County. For modeling & laser cutting. A visit to your local equivalent might inspire your photographic but also case modding interest.

I was really excited for this camera as my gripped SLRs with 2.8 zooms are horrible to drag around, and after living a week with an EPL-1 I bought for a friend back in the day was waiting for a large sensor mirrorless. But I am reading that is slow focusing and in general not that intuitive as any of the current mirroreless competitors.
Atm I believe I would rather go for a used RX100 if portability was the priority. Just as big sensor, a tad disengaged shooting exp but very good all around, for the price of a mediocre EF/STM lens.
That said , experienced shooters do ok with iphones...any apsc sensor should do much better with some patience!Edited by pcfoo - 5/15/14 at 3:54pm
