I took this lens to Allan Gardens (along with the 180L macro) to test. The light in the greenhouse is actually quite bright, but autofocus was very bad with the Commlite and often the adapter is unable to achieve focus, especially when the subject is near the minimum focus distance. I gave up after the first few shots and used the lens in manual focus mode for the rest of the shoot, and it worked out quite well. This lens, unlike the 180L macro, did not behave erratically like the macro lenses (100mm and 180mm) and stayed at its intended mode.
At this point, I am pretty disappointed with the Commlite adapter. It's quite obvious that it has not gone through thorough testing with each lens, or perhaps, they know of the issues, but could not do anything about it. I would not recommend this adapter if you intend to use the Canon lenses as your primary or only lenses. It will simply drive you up the wall.
All pictures below were taken with the Sony A7 & Canon EF 135mm f2.8 SF + Commlite AF adapter.
