Sigma 100-200 f4.5
Sigma 100-200 f4.5.
I found this lens tricky to use in that it is a long lens made longer with the adaptor and the zoom is a push/pull with the focus ring being a long way forward of the camera at 200mm so making holding it steady a bit of a challenge! I got the best results from using higher shutter speeds than I would usually use. Also there is a bit of haze on the elements so any pictures with a whiff of the slightest into the light angle resulted in a milkyness in the image. It has a built-in variable close focus function that I've not yet tried. Overall I'm quite pleased with it.
