Since the two photos on cryptomundo have different aspect ratios, I think we can assume that they are cropped, and if they were real, it would be reasonable to assume that they were taken with a normal or wide lens such as one might find on a cheap point and shoot camera, then cropped to the max. This is why most of the pictures we get of Champ and Nessie and the like are so awful. The best supposed picture of Champ was taken with an instamatic camera at considerable distance on ordinary film, and the cropped detail is so compromised by grain, lens quality and glare off the water that it could be anything you want it to be.
Not that I think for a moment that these new shots are real. Way too many problems with shadows, wake, provenance, angle, physiology, etc. But if they were real, the blurring could be explained easily enough. Like crows at the glint of a gun barrel, it seems lake monsters and sasquatches can sense a telephoto lens from a mile away.
ETA, by the way, looking at the pictures again, there's a real problem with depth of field. If the images are cropped from a distant shot with a normal lens, the foreground should not be so blurry, especially in daylight when you would expect a fairly small aperture. It suggests that the monster was quite close to the camera, or that a very long telephoto lens with very shallow depth of field was used. In the first case, it would mean that the monster is a model. In the second, you would not expect to see evidence of cropping. And in either, it makes it hard to excuse the lack of detail, unless it was done on purpose to obfuscate.
