Nikon just announced the replacement to the D3200: the D3300. This is an entry-level DSLR that competes well with mid-level DSLRs. The D3200 just came out last year, so what major innovations spark a new model?
Well, the headliner is that Nikon removed the anti-aliasing filter. This will increase sharpness and resolution, but at the expense of possible moire pattern distortion. Not really a big deal, because sharpness depends more on the lens and technique than anything else, but this is the trend, so I'm sure Nikon sees dollar signs with this.
The second change is that Nikon improved the software built into the camera. This makes the camera slightly faster, but the differences are incredibly minor.
Perhaps the biggest change is the kit 18-55mm lens, which is smaller and lighter than Nikon's previous kit lens. I guess that's cool, but, again, not a big deal.
The biggest news here is that with the D3300 coming out soon, the price of the D3200 will drop as stores try to get rid of them. If you are considering the D3200, you may want to wait a few months and save yourself a little cash.
