Hello, i am stuck between the canon rebel t4i and the nikon d3200. The nikon has 24 megapixels, whilst the t4i has 18. I have a retina display macbook pro and i will be wanting to take pictures up to 2880x1800 in size. Can the t4i handle this? I like everything else about the t4i. I will be shooting pictures of nature and also taking video. Can you explain how many megapixels i need and what they do? Will i be able to take 2880x1800 pics with the t4i? With the d3200? all feedback is appreciated; thanks so much in advance :)
