"驚くべきシャープな仕上がり"

フェーズワンデジタル１２０mm f.4 マクロレンズで撮る大自然

Performance

Wildlife pictures are ‘all about the image quality’ according to leading UK photographer Andy Astbury. “Stock agencies demand high quality [digital] files, so if two photographers have shot a similar image, guess which one is going to get the sale?” Andy was recently introduced to the Phase One 645 using a P 30+ and 120mm lens. First impressions of the Phase One system were favorable as he feels, “It is well constructed and very well balanced and it’s not noticeably heavier than a pro Nikon or Canon body. The controls are very intuitive and it is extremely robust and able to stand up to any rough handling that you can throw at it – it is not fragile in any way.” He explains that his Close-up and Macro images of this kind are commonly captured with an aperture setting between f.11 and f.16 and says there’s no negative real quality problem using an ISO rating up to 800. Shutter speeds settings can, of course, vary but he claims to have tested the gear with exposures up to 5 minutes with no image degradation. Andy’s dedication to producing the highest quality image files means that he meticulously inspects his final images with some surprising results, “I shot an image of a Damsel fly (not to be confused with a Dragon fly that is much bigger) and, for the first time, I could see the detail of the compound eye structure, an area that is 2 square millimeters. I knew it was there but I’ve never actually seen it using a DSLR”.

He goes on to describe the 120mm lens as, “Staggeringly sharp,” and says that it produces no distortion and no chromatic aberrations. But while he insists that, in certain circumstances, wildlife photographers will have to make the switch to medium format cameras in the future to stay competitive; he adds a footnote stating that longer focal length lenses are needed in the Phase One system to really satisfy the needs of the professional wildlife photographer.
