Have you considered the value of Time --- reduce the ISO - put the camera on a tripod & take a longer exposure -- Then compare your photos -- high ISO vs low/Lower ISO --- In either case you don't need to buy Fast Glass
I always do as I use film quite often and with film with ISO of 400 or so is too grainny for my taste. Most of my subjects can certainly photographed with a tripod and low ISO and slow lens but often they are where tripod is either prohibited, would bother other people or simply too much of a pain to bring it with me.

Why I like fast glass -----
Reminds me of an old automotive term --- There is no replacement for displacement

Thanks for the GAS pump, Steve!

"Thus, for portrait work, an 85mm f/1.8 Nikkor is preferable."
Bob, an 85mm f1.8 lens is a great lens for portraits but a 100mm or a 135mm is even better. I am not a fan of using portrait lenses wide open. In the studio surely it is not needed and outdoors with careful placing of the subject any of these lenses will blur the background without resorting to the widest aperture. With the lens closer to the subject the background at f5.6 is going to be blurred, assuming the background is not too close to the subject, more so with a camera with a so called "full frame" sensor. The advantage of the f5.6 opening is that it will allow a sharper image and will bring better texture on the skin if that is preferable.
I know that many photographers love to shoot portraits with the lens wide open but there are many others that do not. If the photographer knows what he is doing blurring the background at other apertures should not be an issue regardless of the size of the sensor.

In found it interesting as I shot wildlife and the only reason I posted it. The 600mm F4 require high ISOs to get the shot and not as a crutch, I have yet had a Moose, Bear, Elk ect pose or wait for good light. So many on this site are blinded by what they shoot and don't consider how many subjects are out there.

What's right for you is not necessarily right for me, and vice versa....
