What’s New: The Nikon D7100
Nikon announced the D7100 this week, a 24.1 megapixel APS-C HD-SLR with a few surprising developments and unique features for a DSLR in its class.
The D7100 can boast several big improvements over the D7000 (Nikon Rumors has a thorough comparison): 8 more megapixels, 51 AF points (that’s 12 more than the D7000 and on par with the D300s), and some fancy new accessories like the WU-1a Wireless Mobile Adapter and WR-1 Wireless Remote Controller.
We are most intrigued, though, by Nikon’s decision to remove the optical low pass filter (OLPF – also referred to as an anti-aliasing filter). Nikon has done this before, with the D800E, but then buyers were able to choose between the D800 (with the OLPF) and the D800E (without the OLPF).
What does this OLPF thingamajig do, you ask? That’s a good question. The Wikipedia page on optical low pass filters explains them well. Traditionally they’ve been used to reduce the likelihood of moiré at the expense of image sharpness. Nikon explores the relationship between optical low pass filters an moiré in a great article they put together about the D800 and D800E.
Nikon is claiming that moiré is no longer an issue — that they’ve effectively conquered it. And with OLPF now obsolete we can remove it and have even sharper images.Nikon says they’ve “specially designed its 24.1-megapixel DX-format CMOS sensor without using an optical low pass filter (OLPF), resulting in the purest, sharpest images using D7100′s DX-format CMOS sensor.”
All this technical jargon may be making your eyes glaze over, but if Nikon truly believes moiré is no longer an issue and that their cameras no longer need the OLPF this marks an exciting change from they way DSLR sensors have been traditionally designed.
We can’t wait to try it out and see the improved sharpness. Everyone loves the camera thus far, including the previewers over at DP Review that have already had a chance to play with a prototype.
We are expecting the D7100 to arrive in mid to late March. Get your orders in now for the D7100 (body only) for $1199.00 or the D7100 kit with the AF-S 18-105mm f/3.5-5.6 VR for $1599.00 at http://www.calumetphoto.com.
