I am having a hard time comparing photos at various iso's between the two in real life around the house shots any suggestions that anyone has would be great on how to test this during my return period. So far it has better color saturation and lower noise but it's still there. Maybe it's the kit lens but if so that's all I can afford right now. Ohh yeah and I do like the auto shutter speed you can set. Those who said it does not work just don't realize if the camera cannot shoot at your max set iso it will lower the shutter speed. That is a good thing. It's like people would want it not to work. Either way any good testing suggestions would be great. Also it seems like the 24-105 is really not that far of a zoom. I think if I keep it I will have to invest in a zoom before a prime.
