Yes, John. I have used mine with a 2.5/135mm many times. I have used it for concert shots and for long distance panoramas. This one was shot with this combo: http://www.flickr.com/photos/bladt/41643010/in/set-877712/
The lack of sharpness is motion blur (subject/camera), not caused by the lens. So, don't forget that the converter will "eat some light" - perhaps 1½ F-stop. If you have enough light, it's fabulous. If you don't a FA 2.8/200mm, a FA* 2.8/80-200mm (both rather expensive) or a K 2.5/200mm (if you can find one) may be a better choise. And this panrama was made with this combo as well: http://gallery13117.fotopic.net/p21530701.html Try to watch it in full size - it's incredibly sharp - you can clearly see steel wires rather far away. I the mittle of the picture (to the right of the blue chimney) is a steel pylon (for TV broadcast). It is possible to count the small steel beams inside this pylon (in the original picture). This pylon is apr. 15 km away from where I was standing. The beams are perhaps one inch thick. Amazing, don't you think?

Has anyone any exprience of using the converter with the SMC 135mm f/2.5, I've been considering looking for one seconhand for some time, I'm currently using the FA 135 f/2.8 with a Kenko SHQ 1.5x converter as my 200mm AF lens and wondered if there would be any advantage optically other than a slight increase in FL.
