![]() Stopping down to ƒ/2.8 shows the first dramatic improvement, with tack-sharp (1 blur unit) results in the generous central sweet spot and only marginally soft corners (1.5-2.5 blur units). Sharpness improves as the lens is stopped down, with a sweet spot of sharpness developing in the center of the frame (~1.5 blur units) pushing out to slightly soft corners (~3 blur units). Mounted on the D200 and shot wide open at ƒ/1.4, we note an average of 2.5-3 blur units across the frame, with the top right corner showing upwards of 5 blur units. Our sample of the 50mm ƒ/1.4 shows signs of slight de-centering. By ƒ/2.8 it improves dramatically, and becomes tack sharp at smaller apertures. The 50mm ƒ/1.4 AF-D is slightly soft when used wide open, or even stopped down to ƒ/2. The lens is currently available for approximately $325. The lens takes 52mm filters, and an optional HR-2 screw-in lens hood is available. ![]()
