I have been using a D3200 for 2 years and am thinking about upgrading. My main dissatisfaction with the D3200 stems from the time it takes for me to switch focus modes--from single point auto focus to auto area. I have to hit the info button, scroll down to the focus points, click, then select a focus point. My research leads me to believe that I could change focus points more quickly by using the function button on the D5300. Am I correct and do any of you have other suggestions for me? Weight is a consideration so I prefer the cropped sensor cameras. Thanks.
