Q: 1. Will this work in continous focus or AFC mode .. i'll be using sigma 17-50mm f 2.8 lens with lumix s5 ?

A: Yes. Just be mindful it take power to continuously focus on the following system.

Q: 2. Would I have to buy another part to use for my Nikon 70-200mm lens? Have bought 4 of the Manfrotto 200PL Quick Release Plates and they always end up slipping in Vertical position... especially when on a cross country road trip. Grrr!

A: Hi John,Yes, the 3 lens plate. a href= https://www.bhphotovideo.com/c/product/736397-REG/Acratech_2181_Quick_Release_Lens_Plate.html target= _blank https://www.bhphotovideo.com/c/product/736397-REG/Acratech_2181_Quick_Release_Lens_Plate.html/aYou will notice from the picture that the lip is on the end. This is what keeps it slipping when recomposing your shot. Many of the Nikon lenses have two mounting holes, thus we include the two screws with the 3 inch plate even though it works with many other brands of lenses. Use the two screws in the package and the plate should not budge a bit.I hope this helps.

Q: 3. Can this plate works with Canon 5D Mark IV?

A: Yes, this plate also works for the Canon 5D Mark IV

Q: 4. Will the Viltrox EF-L adapter allow full Canon EF lens to Leica CL body communication as well as IS, auto focus and auto aperture setting?

A: It depends if the specific lens that you are using was setup in the firmware that the adapter has. If it was autofocus, body communication, IS, and auto aperture will work. I don't see a compatibility list online though so only way to know is to try it out. Also bare in mind that autofocus tends to slow down with the adapter, specially in video mode it tends to be only manual focus.

Q: 5. This 2167 or a generic cork plate 2128? I have always loved my Slik cork plates as they bake into the rubber of the camera and don't slip, ever, but I am curious if this bare metal is some way special. Thanks!

A: I purchased this base plate for my D800 and a further plate for my D4. For me these plates are a thing of engineering beauty, they fit the contours of the cameras like a glove with the curved lip preventing any slippage even with big heavy lenses like my 70-200 f2.8 VRII. The only downside (and I'm being picky here) is the alan key needed to attach the plate to the camera base. I can never find it when I need it which can sometimes prove to be APITA.

Q: 6. Your response did not answer my question. Is it possible to till less than the maximum if desired ?? That is say 5 degrees instead of the described 9 or 10 degrees ??

Q: 7. Does it restrict image circle? Canon EF is not a digital MF lens mount. Does it cut off the 6x6 Bronica image circle?

A: The FotodioX Pro Lens Mount Adapter Kit for Bronica S-Mount Lens to Fujifilm G-Mount Camera does not restrict the image circle of a lens attached to it; however, an EF or EF-S lens would not have a big enough image circle to cover an area larger than full frame--both the Bronica and the Fujifilm G-mount sensors are larger than full frame.

Q: 8. Will this crop the image? Compared to when using it on bronica body?

A: Yes there will be a crop factor when using this adapter on full frame or APS-C type Sony E mount cameras.
