lol. The memory manufactures are happy campers.

Of course, with the exception of the D800 right? As a student photographer, there are instances when we make prints up to 20 inches for more serious projects that get posted in a gallery. I find this camera for people that need bigger prints without getting themselves cameras like a D800. I actually think this camera fits a student photographer.

OK, I'm going to admit this to myself, and publicly. I don't understand full-fram / APS-C. This camera, with 24.2-megapixels is not full-frame? I don't get it.
Hi Ned,
APS-C vs. full-frame is all about the physical size of the sensor, rather than the megapixel count. The D3200's sensor is 23.6mm by 15.7mm, while a full-frame sensor measures 36mm by 24mm.

Just to add a little more 'laymen's terminology' to help Ned.... The full frame sensor (In Nikon world it's 'FX'), is like a 35mm negative size approximately, which means that, with an FX lens, you not only capture more of the image at the top and bottom, the captured image crops much better into a 8x10 or 5x7 than the DX or APS-C format... With the APS-C format sensor, your image is 'wider' i.e., imagine snipping off some of the top and bottom of a full frame captured image). For a lot of shots this is okay, but what you'll find is that when you shoot a group of people and you fill the APS-C frame left to right in your viewfinder with people, when you go to print an 8x10 or 5x7 you're going to be either cutting off something on the left and/or right, or having to edit the image in something like Photoshop to add a border on the top and/or bottom (kind of like the wide-screen letterbox effect)... Which, incidentally, also means that if you show your images on a wide-screen type TV or flat panel display (a 16:9 format), then the APS-C format gives you full display width... Meaning if you're shooting video with it the APS-C format is okay).

If you do the math you'll find that both the FX(full frame) and the DX(aps-c) are identical aspect ratios - just different multipliers - 36(3x12)x24(2x12) is an aspect ratio of 2 by 3.....rounding up - 24(3x8)x16(2x8) is still an aspect ratio of 2 by 3. It is the back-focus image area dimension that is different. That is why when you put a FX(full frame) lense on a DX sensor the image magnification is increased by 50% (50mm = 75mm actual)and you cannot put a DX lense on a FX camera because the back-focus simply won't cover the sensor. That is unless you're using a D700 which automatically reduces the shooting resolution when a DX lense is mounted on that camera.
