Two new fisheye APS-C lens from Sigma

Sigma has for the first time marketed a true fisheye optic for crop sensors, projecting a circular 180° image onto APS-C sensors. The new lens sports a focal length of 4.5mm and maximum aperture of f/2.8.



The other type of fisheye lens available is the diagonal variety which squeezes a 180° angle of view into a standard rectangular format. This new 10mm F2.8 EX DC Fisheye HSM from Sigma is just such a lens. That said, it captures a true 180° vista only when mounted in front of a Nikon DX sensor - users of Canon and Sigma DSLRs make do with 167° and 154° respectively. A built-in lens hood and HSM focusing are here and the lens will focus down to 1.8cm (0.7 in) from the front surface of the lens giving a reproduction ratio of 1:3.3.

If you've worked on a network with Windows servers, you've encountered this error message many times:


This problem happens because Windows only allows two remote terminal services connections when you are in administrative mode, and you've either got two people already on that server, or more likely, you've got a disconnected session that still thinks it is active.

I found two articles that offer solutions:
