Q: 3. I have a Fuji S5 which is a DX camera with a 1.5 factor. I want to use my Tamron 90mm 2.8 Macro lens with the Nikon ES-1 Slide Copying Adapter for slide copying. Which extension tube do I use for a perfect 1 to 1 or a combination there of? Thanks in advance

A: The Nikon ES-1 Slide Copying Adapter enables slide copying with a Nikkor 55mm f/2.8 Micro-Nikkor lens and PK-13 Extension Tube. Because your S5s sensor is smaller than a 35mm film frame, 1:1 will mean cropping your originals. The best way to do this is with a dedicated film scanner. Even a low cost scanner will produce better results than your camera.The SNAP14 14MP Digital Image Converter from Wolverine is a powerful yet easy-to-use device that can preserve all of your old photos, 35mm slides and film negatives forever. Combining a 14MP CMOS sensor, built-in color display, internal memory and an SD memory card reader, you can easily convert 35mm slides, negatives and photos into digital images. The innovative design of the SNAP14 can scan and convert this media in seconds, without being tethered to a computer: http://bhpho.to/UvWkYj

Q: 8. will these extension tubes work with Nikon D810?

A: I use them on my Nikon D800E. They all have the same mount. I prefer using a Nikon 105mm f/2.8G ED-IF AF-S VR Macro Lens. The extension tubes requires adding/removing them for changing the amount of macro enlargement. That is OK indoors but not preferred in the field.

A: The Vello Auto Extension Tubes for Nikon Z-Mount Lenses will decrease the point of focus so you can show more detail of a small item like a diamond on a ring. The issue is that you won't be able to focus to infinity any longer with the extension tube on the camera.
