Roger Cicala of LensRentals has revealed the winners of his 'First Annual Photogeek Geek Photo Contest'. What was originally intended as a light-hearted joke ended up receiving over 400 entries from at least 20 countries, and the impressive quality of the entries caused a real headache for the judges.

After a lot of deliberation, Rishi Sanyal won 'Best in Show' for his remarkable 'MacroSetUp' series. Using a whole array of accessories between his Sony NEX 6 and Canon MP-E 65mm f/2.5 1-5x Macro lens, he took pixel-peeping to extremes by imaging sub-pixel structures in the Retina display of his MacBook Pro, which he estimated as just 4μm in width (i.e. less than 0.2 thousands of an inch). 

Rishi Sanyal's winning entry included this image of his MacBook Pro's Retina display. The original image shows clear sub-structures within each individual pixel.  
Rishi's macro setup included bellows, extension tubes and a teleconverter between his NEX-6 and Canon 65mm f/2.8 Macro lens

Aside from this impressive effort, the winners covered the full spectrum of photographic subjects, from cats to cathedrals via teapots(!). Click the links below to read Roger's full roundup (which is entertaining as ever), and to browse through the full gallery of uber-geeky entries.
