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.
Wow! Bummer!
ReplyDeleteI wonder about the Techart adaptor (¿)
ReplyDeleteI think the Techart is better, but then again, I don't know for sure until I get a chance to use it. It's quite a bit more expensive.
DeleteI have this adapter, and it works very well with my Canon 40mm STM and surprisingly with my cheapo Sigma 18-50mm that I got at the Henry's Outlet, to use for IR photography with my Canons.
ReplyDeleteNow, with the adapter, I use the,mom my NEX 5R. No issues with those two lenses.
But, there's always a but, the adapter does give issues when in AF, with my other Canon and Sigma glass. Put them in manual mode and the adapter lets me change f-stops and no camera issues.
Not sure why when it's it AF mode, that it acts up on those other lenses.
