Let me throw in my 2 cents. I've had the 85 1.4 D for quite a while, dating back to my first DSLR which was a D70. I then moved to D200 and I'm now using a D700. During all this time I also use a 17-55 2.8 (works really well on D700 with a Kenko TC), and a 70-200 2.8. All of thee lenses are exceptional pieces of engineering marvels. However each has its unique features and uses. I've seen above where one poster does not recommend the 85 1.4 for a crop sensor body, I on the other hand will endorse that lens for either full frame or crop. True, the angle of view is a bit tight for torso/full body shots in a small room but the rendering of the image is very very nice. As one poster says, the rendering of the out of focus elements is buttery smooth making the subject simply jump out of the image. You would not be disappointed with this lens should you acquire one. If your camera can focus D lenses don't discount the older 85 1.4D, reviewers and pixel peepers aside, this lens still absolutely shines.
The 17-55 2.8 is an older design for DX cameras but it also is no slouch when it comes to performance. I found it had a very useful zoom range on my D70 and D200. It was continually mounted to one of the D200 bodies. The color and contrast of that lens is very nice indeed. True the 24-70 outperforms this lens in a few aspects especially important to critical reviewers but for the pro/advanced amateur I feel this lens has a lot to offer. The build is top of the line, this lens is one of the best built zooms I've had. I've used in the dusty environments of production shops, in the pouring rain, in the arctic, in the deserts, it's been dropped, and still this lens performs flawlessly. Besides, with the current craze for FF 24-70, excellent 17-55 examples can be had second hand at reasonable prices.
