Oh dear, people have been using the wrong FAIR model. You need to use the Defence Aviation one in the Manual of Air Safety. See page 44:

Was there a conscious, substantial and unjustifiable disregard for risk?
No, but only just!
Were the rules broken intentionally?
Yes, he took a personal item of equipment onto the flight deck.
Given the condition at the time could the task been done in accordance with the rules?
Yes, he didn't need the camera.
Was the action to the benefit of the individual?
Yes, he would get some nice pictures for his personal collection.
That means under DA-FAIR it crosses the 'red line' as "Selfish Rule Breaking / Violation". If I were really hard nosed about it and answer "yes" to the first question then it would be "Recklessness".
Now the fact that he has caused permanent injury to his crew and passengers - all of which trusted their lives to his impeccable behaviour - he has to be punished. Is it too harsh? Ask those with injuries they will have to suffer from for the rest of their lives.
Sorry, but consequences always have a bearing on the level of punishment. He has been punished for what he has done - intentionally or unintentionally.
