So a lot of people with the (expensive) Metabones EF Lens to Sony NEX Smart Adapter (Mark IV) and even with the Viltrox EF-NEX II (for around 100-130 EUR) have odd lens connection issues so that the A7s does not boot up / screen stays black or does not allow to change aperture / iris especially after switching batteries. But with the Viltox I even sometimes had aperture / iris change issues all of a sudden while shooting.
And there seems to be no real solution to the issues.
So I just got the Commlite to test that one out… and so far it seems to work nicely… SO YES NO LENS CONNECTION ISSUES AT ALL!
Autofocus seem a lil bit better but not really…
but if u need AF you kinda have to go with nativ SONY FE lenses!
You have to a bit careful when you buy the Commlite there still are some old version out there that do not support Fullframe lenses … so make sure you get the new version.
I've started using Sigma's 48 megapixel DP3 Merrill, the giant size portrait camera that fits in the palm of a hand, during fashion shoots. The true color fidelity of the Foveon APS-C sensor along with the ultra sharp Sigma fixed 50mm f/2.8 lens are perfect for making super high resolution photographs without having to pull out the Hasselblad.
With a Pocket Wizard in the hot shoe and one of Hoodman's custom finder kits making the camera's monitor a huge viewfinder the DP3 is super easy to use in the studio or on location. I also use Hoodman RAW Steel SD cards with it. Below are some useful links: sigmaphoto.com/product/dp3-merrill-compact-digital-camera-0 hoodmanusa.com/products.asp?dept=1079 pocketwizard.com
