Jordan Drake and Chris Niccolls over at DPReview TV recently published a follow-up to their lens cleaning video, where they tested something that we've all wondered: how much do scratches, dust, water droplets, and fingerprints on your lens really impact image quality?
It has been widely reported that the new Nikon D600 full-frame DSLR suffers from a higher-than-normal amount of dark spots appearing on the sensor. Yesterday we shared one photographer's time-lapse video that demonstrates that the issue occurs right out of the box without any lens swaps.
Photographer Daniel Gaworski has been experiencing the same problem, and decided to take a closer look at his D600. He discovered that his camera's shutter curtain contains scratch marks on the bottom flap (see above), particularly in one corner of the camera.
This photograph was taken by a lens with some "obstruction" on the front element. Aside from the blurry patch of nastiness in the bottom portion of the frame, the rest of the image looks pretty decent. What do you think the "obstruction" is? A little dirt? A smudge where the photographer accidentally touched the front element? A scratch? The answer is a little closer to a scratch than a smudge...
