加個 KENKO TUBE 得唔得... D800E 用舊鏡會起沙...

有人用D600做測試... http://www.flickr.com/photos/dnk ... t-72157632804181238
佢毫無保留咁話200/4濕過70-200/4...  雖然話70-200/4都夠用 
As far as image quality goes, the 70-200 f/4 Micro performed admirably. ... The extension tube configurations were quite near pixel sharp, although you pay a price in terms of light
Obviously, the 200 f/4 Micro remains as a gold standard even at today's high MPixel resolutions. When I tried it on the D600 at distance, I was kind of stunned to see what 24 Mpixels really looks like edge-to-edge. It is also obviously a true macro lens with flat field and very little distortion (which often isn't critical for some natural work). Even more importantly, there is a subjective realism to the 200 f/4 Micro images that isn't matched by the other combinations, especially in test shots with shallower DoF. Any thoughts that I had of selling it have faded. :D
I would not hesitate for a moment to use the 70-200 f/4 for closeup work, either with tubes or with the 5T diopter. In fact, with a bit of sharpening and more attention, I think the 5T image could be enhanced to work well enough for most purposes. |
