The A2X-S works well with every lens I've tried it on, although I've never attached it to a lens shorter than 135. It isn't limited to lenses under 300mm. It's just that the A2X-L is designed specifically for longer glass. Some long glass, such as all the 400/5.6 variants, can't be used with the L due to it's protruding rear optic. I use the A2X-S with my A400/5.6 quite frequently. It works well. Many of my bird and insect pics were shot with that combo.
