The main problem with the SR is the camera identifying later lenses automatically. The DA*300/4 for example fitted with a 1.5x TC (450mm) is seen only as 300mm with no option to override the setting manually. Therefore you have 450mm with shake reduction set for 300mm, 50% out and it's a PITA. I've winged about it before at length so I won't bore you all anymore with it.

Do the DSLR cameras know when you are using the AF 1.7x teleconverter? Or any teleconverter, for that matter? So when you slap a construct on the camera, do you tell it (for shake reduction info) the focal length of the lens, or the focal length of the combination? My A* 300mm ƒ4.0 with the AF 1.7x. 300mm? or 425mm? Joe On May 11, 2009, at 10:42 , Tim Øsleby wrote: > Focus wise the F 1,7 does a good job with my DA* 300.
