i'm sure it probably will.
the interesting thing about this experiment was that it was for the purpose of doing widefield sky surveys with just a camera lens and it was able to detect hot Jupiter sized transits. the paper mentions that dslr users like to use a defocus method but this isn't that appropriate for survey work.
there is a whole bunch of interesting points on DSLR's themselves eg part of the sensor should be cropped out, their linear nature. also interesting they used a low ISO.
