Nikon: Please make a DX 22mm f/2 for ~$422
FX cameras are great in low light and have great lenses to choose from. However, an FX camera can be overkill in terms of weight and price for someone who simply wants great low light family photographs, without a flash, and within the confines of a house or apartment.
The DX 35mm f/1.8 is a fantastic low light lens and ALMOST meets this need. However, it is not wide enough for use within average household rooms.
The family of DX 18-XXXmm zooms provide plenty of wide angle coverage. However, at f/3.5, they often require either higher ISO's or flash assistance within a home lighting environment. VR, as great as it is, does not help with moving subjects.
A DX 18-35mm f/1.8 would be a great lens. However, it would come with a significant weight and price premium that still makes a DX 22mm f/2 more desirable. With the high resolution capabilities of DX cameras, users can easily zoom from 22mm to 35mm via software cropping and still have a very high quality image.
(The creator of this petition has a D300, D5200 and plans to buy the next D7xxx camera. He also has a DX 18-200mm f/3.5-5.6 VR, DX 35mm f/1.8, 50mm f/1.4, 105mm f/2.8 micro, and 70-200mm f/2.8 VR. If Nikon makes a DX 22mm f/2 he will permanently mount it to a D3xxx to create, and promote as, the ultimate affordable low light camera.)
Please, make a DX 22mm f/2 prime or similar lens. It is possibly the most important lens missing from the Nikon DX lineup and for some would become the most important lens in their bag.
