<p>Kent, what others said is exactly what I do.</p>
<p>You can also keep an eye on the excellent Voigtlander SL II glass, most of it using 52mm filters, three of them having between 180-205g. All of them are compact, with a great build quality, surpassing that of Nikon legacy glass. The big advantage is that they are AI-P lenses, being factory chipped. I do have three: 20/3.5 40/2 and 58/1.4. But I'm lusting for 28/2.8 and 90/3.5, hoping that one day I'll add to my kit. Their focusing ring is very creamy, being a real pleasure to work with it. Their IQ is really excelent, on par with D800, only 20/3.5 being just OK but improving stopped down. They are pocketable lenses, being perfect when you need less intimidating glass or when you want to travel without a heavy bag.</p>
<p>There is also a sweet Nikon 45/2.8 AI-P with a Tessar design, 4 elements in 3 groups, having only 120g, that's very good too. You can use it as a body cap too, due its pancake design :) The only disadvantage, I found it too small for my fingers... preferring Voigtlander 40/2 which offers one stop more light as well.</p>
