Q: 1. would this lens work on an a7s in a nauticam housing for underwater macro shots? Looks like it is full manual so is there a focus gear you can get for it?

A: Yes it works w the a7s

Q: 2. Can the shift only go along one axis (say, left-right when in landscape mode) or is there an internal rotation to let it also shift up-down (while still in landscape)?

A: It only allows up/down in Landscape mode, no rotation. Also the shift does not work with full frame sensors, part of the image corners will be cropped.

Q: 3. The screw/tab thing on the bottom by the cap, what is it?

A: If you are referring to the lever at the end of the lens closest to the camera, that is for shift. It is not a tilt/shift lens but works a little like one. You can shift the lens in one direction up to about 6mm.

Q: 4. Is this Len comp with Nikon d5100,7100&7200 cameras ?

A: yes, but it is all manual

Q: 5. Can someone with the Sony E mount version of the lens measure the height for me without the hood? I notice all the variants list a 3.3inch height, so clearly the sony mount one isn't adding the extra hight of the adapter that's basically fixed to the lens.

A: The manufacturer does not list the dimension and B&H agents are not able to open boxes to measure so our guesstimate is a length of 5.3".

Q: 6. How does this lens perform when the camera is set to bracketing, especially in full frame canon and Nikon cameras? Has anybody tested this?

A: This lens is fully manual in terms of aperture control and focus. If putting the camera in an auto bracket mode, it will not control the exposure through the lens. Manual bracketing would need to be performed in this case.

Q: 7. could this lens be useful for landscape photography?

A: This lens is not recommended for landscape photography, it is excellent for macro photography with clear background, this company has a 15 mm f2 lens which is good and recommended for landscape photography

Q: 10. What happens when you mount the Canon EF lens version on a adapter to suit it to a Sony A7iii camera? The image quality changes and the aperture range changes correct?

A: The image quality usually doesn't change much when using an adapter and the exposure doesn't either. Most adapters don't support autofocus, so if you put an autofocus lens on with an adapter, you might have to focus manually. There are good adapters for Canon mount lenses that will support autofocus on a Sony camera.
