Lord Magnus- I avoided buying the 250mm lens pair because it makes the camera so front heavy and difficult to handle even with the L grip without a tripod, and the shutter needs to be cocked manually, not as you wind on like the other lenses, I avoided the 65mm lenses because to me It's too close in angle of view to the 80mm to make it a worthwhile buy, I got the 55mm about twenty years ago, and found this a good wideangle, able to get 1:1 close up by extending the bellows.
