Same as a few others here, I have the silver body with black lens. 12-50 kit. I personally chose the silver body over the black one but as for the lens kit, I didn't care what color it was Make sure to read the description to make sure it is what you want before you buy. Try contacting or making a special request if the seller can make the change for you.
Similar to others, I have the silver body, and black 12-50mm kit lens. It's possible to order the silver body and the silver 12-50mm separately, rather than as a "kit", but this will cost $200 more than the body+black lens kit. Olympus doesn't explain why it only offers the black lens in the kit purchase.
