Canon EF Lens with Signstek Newest Version Electronic Auto Focus EF-NEX EF-EMOUNT FX Lens Mount Adap
1

Got a new a6000 with the 16-50 kit lens and the Sony 55-210 lens and I am really pleased with the result. The 16-50mm kit lens is not as bad as I had thought it would be and the 55-210mm exceeded my expectations. I have a Canon 5D Mk II with a Canon 24-105 EF 1:4 L lens, a Sigma 12-24mm 1:4.5-5.8 DG HSM and a Canon EF 70-300mm 1:4-5.6 IS that I wanted to see if I could use the Canon EF lens with full functionality on the a6000. I purchased the Signstek adaptor on Amazon for $109 and tried out the lenses.

The Sigma 12-24mm worked reasonably well, it hunted quite a bit on Auto focus, especially at 12mm. I changed the focus area to "Center" and focus accuracy and time to focus was much better, not as good as the 5D, however. On the Canon 24-105mm focus was slower than 5D, but not much slower. The Canon 70-300mm worked really well. Aperture control was there on all the lenses and the photos were more than acceptable. It would appear this EF and EFS to E adaptor works really well, maybe as good as the Metabones III from what I read about that adaptor.

Check out the photos, these were all hand held used the Program mode, auto focus on all the lenses, but not shot all on the same day, so lighting conditions were different. I am please to able to use my legacy Canon lenses with almost full functionality.

Yes it did. It definitely powered the IS on the 100-300mm Canon and 24-105mm Canon.

there are two of the EF 70-300mm IS zooms from Canon. This landscape at 300mm seems rather poor, perhaps due to a substantial haze in the air

Thanks for sharing your pics and the info. BTW, how is the AF speed? is your 24-205L as fast with your 5d with the adapter on the sony?

No, it hunts a little bit before locking in. But, it is acceptable for my uses, definitely not for action shots.

The Canon lens is the 70-300mm 1:4-5.6 IS USM.

Yes, these shots are in CO and we were getting smoke and haze from wildfires in CA and OR.

I can live with that. I intend to use it for portraits. If it won't hunt 2-3 seconds or more in decent light, it's good enough for me. If it's just 0.5-1.5 sec. I can live with that hunting. I'll be using f2.8 lenses, so I suppose that should help in AFing?

To recap, it offers AF and IS on EF lenses. Does it support EF-S lenses?

Re: Canon EF Len Mount Adap

I don't have any EF-S lenses, so I haven't tried.
