I admit that I am/have been a bit of a kit lens snob.
Always searching for fast lenses, better bokeh, and of course, paying the price.
Tonight I thought I would try out the Nikon 55-200mm DX (probably F4.5-5.6 or similar), which cost me a whole £22.
I am surprised at the output. Obviously its at the long end, but there is some subject isolation and sharpness with slower lenses is rarely a concern.
So I dug out a couple of others, namely Sony and Panasonic, and even one from the now ancient NEX 5n, at ISO 6400 F8.0, indoors without flash! (above)
But across the board they offer consistent, and somewhat impressive performance.
The Sony above appears to pip the Nikon, but the below shot was at ISO 10,000 with the 18-105mm at F4.5 so I’m not knocking it.
