Perhaps there is a simpler method for testing whether, or not, the K-5's sensor might be generating some purple fringing:
If someone, who owns both a K-5 and one of the above lenses, would mount this lens on his/her K-5 and do his/her best to photograph, say, the sun behind tree branches/leaves, would the resulting photographs enable a determination of whether, or not, the K-5's sensor might be generating some purple fringing?
For example:
Result 1: There is NO purple fringing in the photographs. Would this absolve the k-5's sensor of complicity in generating purple fringing?
Result 2: There IS purple fringing in the photographs. Would this indicate the K-5's sensor does, in fact, generate purple fringing?
Just a thought.
