You were right. I went ahead and got the 35mm f/1.8 G DX lens and now want to get that 70-200 f/2.8, as well as upgrade to a Nikon D5500 or D5600. I love this camera (D3100) and learned a great deal about photography from it. I've gone away from full auto mode, and learned to set my own aperture, ISO, shutter speed, etc. I've also been shooting in RAW and doing my post processing using either View NX-2 or Adobe Elements 6. I think I've begun to outgrow my D3100; the 14.2 MP is sufficient, but I want to be able to crop, therefore I would like to get a 24MP camera.
