I'm trying to say goodbye to my 24-105 but I'm not willing to sell it at lower than purchase price. We are know it's incredibly cheap now. If it's discontinued next year do you think the price would trend up a bit? On the other hand I'm concerned more people will be interested in the sigma version or maybe canon 24-70 f4. What do you suggest I do? Cut loose or wait? It's collecting dust now but I don't urgently need the money.
