Lens Test REPORT
List of tested lenses
[ 1 ] This installer contains two DLL libraries. Therefore, you can control two devices at the same time. This can be useful when controlling two lenses (on the main and guide camera or on a color and monochrome camera). [ 2 ] Also you can prevent sending of aperture control commands. This function can help you to avoid software malfunction with some third-party lenses. We are aware of one such lens: Sigma 85mm F1.4 DG HSM Art. Focus control works and an attempt to send a command to control the iris leads to the driver freezing. So use the definition below for problem lenses (in lens.txt): "Sigma 85mm F1.4 DG HSM Art | -1" instead of: "Sigma 85mm F1.4 DG HSM Art | 1.4 1.6 1.8 2.0 2.2 2.5 2.8 3.2 3.5 4.0 4.5 5.0 5.6 6.3 7.1 8 9 10 11 13 14 16" [ 3 ] In addition, this version of the driver eliminates possible errors when calling these functions: "TempComp" "TempCompAvailable" The previous version of the driver may cause problems when using some software products (N.I.N.A., SharpCap, PRISM).
