For the first time SLRgear tested a 3D lens. And they had a lot of fun with the new Panasonic 12.5mm lens: “The images were realistic enough that I found myself shifting my head to see if I could see more of a scene by moving to peek around a real opening into 3D space. When you do that, though, the 3D background just appears to float, unmoving, behind the foreground objects, an odd, somewhat unsettling phenomenon that caused a couple of viewer’s queasiness.”
The big problem is that “the very small, and fixed aperture of f/12 limits your shooting to bright daylight.”
Check price and availability of the 3D lens at Amazon, Adorama, B&H, J&R, eBay (Click on shop names to directly visit the lens product page).
