The Voigtlander Ultron 40mm 2.0 SL II is a tiny pancake lens, about an inch long, that has excellent image quality with superb build and usability, but unusually these days the price is reasonable at around £380 inclusive in the UK, or £299 imported from Hong Kong. Comes with hood and a tiny screw in 'close-up' lens for detail shots.
It's particularly suited to street/travel walk-around use on a full-frame with the 40mm length occupying the 'just about right' area between 35mm and 50mm - likely means reduced distortion on portraits/groups but just about wide enough to be useful for scenes and architecture. Personally, I probably prefer wider ideally, but the lens has a number of attributes that mean I'm happy to accept the compromise and adapt.
Build is metal throughout with a beautifully accurate and responsive rubberised focus ring. Comparing this class of focus ring with a typical AF ring is like chalk and cheese. No slop at all. Of course, it's manual focus only but on the D700 there is no problem getting a quick focus given the excellent viewfinder and good focus confirm light. An AF lens will focus much quicker most times, but for street you can stick it at f/8.0 and let DOF take care of most situations. The lens is chipped so no problems using the camera metering system direct from the dial as with other lenses.
In terms of IQ the lens has exceptional sharpness, especially stopped down a tad, with close to Zeiss standard micro-contrast. Colour is extremely accurate in my opinion. Need for post-processing is absolutely minimal.
These kinds of primes are for a minority audience only as most obviously prefer AF. I actually prefer MF myself at these kinda short ranges. More enjoyable to use as I feel more engaged with the process of shooting.
These are some simple samples from the first dozen or shots I've taken with it (at my local pub!) Will post more when I find the time to go shoot again.
