Originally posted by womble It's a bit of a beast. I've had some lovely shots with it, but it's biggest weakness it doesn't have a tripod collar. It is such a heavy lens that I worry about the weight on the camera. I usually use a small extension tube to improve the close-focusing.
The tripod collar would be great, though I guess the intended use case 45 years ago was handheld for sports... but I wish it had one...
But it looks completely serious mounted on a K1... like you're about to shoot something important... because of that bulk...
