So, I'm looking over the specs on the recently announced Nikon D3100 for about the 6th or 7th time, and I'm thinking... hmmm... the Perfect Prime Camera?
Put the Nikon 50mm f1.4G on the D3100, and you've got a light, FAST combo. At 14 megapixels, there's plenty of resolution, and with a top ISO of 12,800 combined with f1.4, you're seeing in the dark.
Don't get me wrong... I'm sure it won't compare to the D3s at those settings, but then what will?
The thing is, if the new sensor in the D3100 is everything I expect, it's gonna be VERY usable at 6400 ISO at f1.4.
For the record, I expect both the D3100 and the D90 replacement (the D7000 for my money) to be a stop to two stops better than the D90 at high ISO. Considering the D90 is the current reigning DX DSLR champ at high ISO, the D3100 and D700 will be beautiful if they're a stop or two better.
So, I'm thinking a D3100 with the Nikon 50mm f1.4G will be a new fixture in my bag. At the low price of the D3100, I could buy one for every prime I have and shoot nothin' but primes. :-)
At 445g / 160z, the D3100 weighs next to nothing. The Nikon 50mm f1.4G is only 280g / 9.9 oz, so that's about a pound and half combined weight. Sweet!
Figure that the 1.5x crop of the D3100 DX sensor makes the 50mm about a 75mm perspective, and you've got a perfect portrait combo.
So, the lowest DSLR in the Nikon line-up may just be the Perfect Prime Camera.
