Canon 400mm f/4 DO IS II Review (Imaging Resource)

SLRGear posted their review of Canon’s new 400mm f/4 DO IS II lens, announced last September for Photokina.

Some excerpts from the review:

• On a full-frame body, the Canon 400mm DO II is sharp, though not as tack sharp as the 400mm ƒ/2.8 II
• As one would hope from a nearly-$7000 lens, chromatic aberration is very minimal. On both full- and sub-frame cameras, CA was very low
• […] vignetting on this telephoto lens is very, very low.
• […] geometric distortion on the Canon 400mm DO II is practically nonexistent
• […] this large lens is, as they say, “built like a tank”. The build quality is simply impressive […]

From the conclusion:

The Canon EF 400mm ƒ/4 DO IS II USM is a fantastic, professional-level supertelephoto lens. As a significant upgrade optically compared to the original version, the 400mm DO II is an even more attractive option over the heavy, expensive 400mm ƒ/2.8L IS II. For professional and serious wildlife, sports and action photographers who don’t want or need a fast, low-light-friendly ƒ/2.8 supertelephoto prime, the 400mm DO II version offers healthy savings in both cost and weight. Image quality is very good, and the built-in I.S is extremely impressive

The review comes with charts and sample pics.

The Canon 400mm f/4 DO IS II lens is not a budget lens. It sells for around $7000 (B&H Photo | Adorama).
