Thanks for the review Neil. I had a chance to check these out, but unfortunately, the copy failed to impress from an optical standpoint (sharpness, glare, CA and distortion control). Oberwerks are certainly great for beginners as they are guaranteed for collimation out of the box from the manufacturer; the limited warranty is only for 2 years. For the price point, I, like Andy W, would rather choose the Nikon.
