Q: 1. - Does this produce any VIGNETTING (like the Vello adapter version with "Aperture control" ring) when using Full Frame Canon Lenses on Panasonic M4/3 camera? - Does it increase the Full Frame to M4/3 CROP Factor (which is calculated as 2x)? Thank you!

A: But I can't recommend it because you won't have any aperture control.

Q: 2. Will this adapter work on Olympus OMD cameras?

A: Yes, the Canon EF/EF-S Lens to Micro Four Thirds Camera Adapter will work on Olympus OM-D cameras, as this line of Olympus cameras have Micro 4/3 lens mounts.

Q: 3. Will this let me attach Canon EF lenses to an Olympus System OM-1 camera body? Will the camera and/or lens lose functionality?

A: Yes, the Viltrox EF-M1 lens mount adapter for Canon EF or EF-S-Mount Lens will allow end-users to mount to any micro four thirds camera system.

Q: 4. does this useful and helpful when i need to use my Canon 50mm 1.4 lens, and 18-55 EF-S sense, also 55-250mm EF-S sense on BlackMagic Pocket camera?

A: There are limitations. 1. You must focus the lens manually. 2. Importantly the lens aperture is not controllable, so you will be shooting wide open.

Q: 5. Does this come with protective caps or a case when not in use ? also- I have a Rokinon 85 1.5 mm cine lens n a tokina 11- 16 mm from a canon 70d -wanted to use on my Pana gh4 - will I come across any problems ? I know I lose auto everything n manual iris - but can I still focus manually or does it become a prime lens having to move closer or back for the tokina lens?

A: The Vello adapter does not come with any case or caps--I was annoyed at that too.There is very little to this, it's literally just a physical metal adapter, no glass or anything, just a spring release switch. If your lens can iris/focus/zoom manually via rings on the lens then you won't have any problems. And the mount actually worked smoother than my metabones speed booster, so good job Vello on that...

Q: 6. I know I'm slow here ... but if an EF or EF-S lens is attached to a Blackmagic Pocket Cinema Camera via this adapter, there will not be any way to control the aperture. Am I understanding this correctly? Thanks!

A: Yes, this is correct - there is no communication between the lens and camera body, and you will have to set your exposures manually.

Q: 7. Is this a focal reducer?

A: This adapter allows EF and EF-S lenses to work on a Micro 4/3 camera. Those lenses will be subject to a crop factor of 2X.

Q: 8. will this work with canon efs 18-55 lens

A: Yes, they are compatible.

Q: 9. Will this work with the modern 'focus by wire' system in the new ef-s lenses focus ring? How does it work if they have to be powered thru the connections? I just need manual focus but this seems impossible.

A: NO, if you use lenses that have AF/MF "by wire" (meaning they need to be powered to actually move focus elements), like the Canon "STM" Lenses, then you will NOT be able to focus. However if you use lot of other lenses (Canon L and non-L versions) that have a Manual Focus ring which doesn't focus "by wire" you will have no problems at all to focus. It all depends on the Lens you mount on it. In fact there are LOT MORE lenses with Real Manual Focus Ring than "Focus by wire".

Q: 10. Does this adapter work well with Canon EF-S10-22 lense?

A: it is good and my customer is happy with this adaptor but it works only with EF to Micro four third not with EF-S
