Thanks for your reply. I would argue that the fashion in Nikon standard zooms right now is slow lenses because Nikon hasn't released a 2.8 standard zoom since 2007 (24-70.) I suspect this is due to the improvements in ISO as you have suggested. However right or wrong, I have no desire to shoot above ISO 1600/3200 and I could produce many images where I needed 2.8 and ISO 1600 to maintain a reasonable shutter speed. And I also do not like to use flash as my primary lighting for a scene. I can handle a little fill...Show more →
For the purposes stated, I've always used either a sigma 18-50 f/2.8 or a nikon 28-70/24-70, not only for shutter speed/ISO/noise control, but for DOF control for portraits. I would not intentionally set out to use a variable aperture, slow lens for low light shots, especially photos of people.
Personally, I would not pick the d600 over the d7100, but that is primarily due to the AF system. If you're staying at reasonable ISO levels, such as the ISO 1600 you mentioned, I wouldn't see any reason to pay the premium for an FX camera.
My sigma is very old, bought in 2005, IIRC, so I am not familiar with the new offerings. I would suggest that if you're comfortable using 3rd party lenses, to buy either the sigma or tamron that suits your fancy, from a place like Amazon. That way, if the lens doesn't meet your needs/expectations, you can return it and pay the premium for the nikon version.
