This lens takes some unworldly pictures. Shadow details tend to be lost, but the contrast and the sharpness are amazingly high. If you purposefully use this lens, it will make a great difference. This unique lens gives so much more excitements than lenses with neutral characteristics. As shown in the sample shots, it will be a great lens for landscapes and urban photography. And, don't forget the price. Corners are a little loose wide open, but the center is extremely sharp and it becomes sharp from edge to edge with 1 or 2 more f-stops. Plus, distortion is minimal. You can get all these performance in this reasonable price! It's a little bigger than the first version because of rangefinder coupling, but it's still much smaller than the 15mm SLR lenses and it's a great lens for traveling.
