Is this extension tube compatible with the Canon -70 - 200mm f/2.8L IS II USM lens. I have tried it on this lens and others and I can't get it to focus manually or automatically. Bad tube?

Will this work with non Canon (Tamron, Sigma etc) lenses?
Asked by: Milton
If the lens has a Canon EF or EF-S mount, it will work - if the lens's focal length is adaptable to the extension. If the lens has autofocus, it will drive its motor and will always work in manual mode. If the lens has a Canon FD or R mount, it will not work.

question

What kind of results can one expect using Canon's 70-300L? How much closer is focusing improved?
Asked by: Daniel D.
Basically you will use this so your Canon EF 70-300mm f/4-5.6L IS USM Lens will be able to focus closer than the lens's native close focusing distance of 3.94' / 1.2 m. We were not able to find information as to how much closer but we would guess that bout 2' would not be unreasonable. People with telephoto lenses by this to do exactly this, get a closer focusing distance. This can be an excellent too.

A 2X converter will double your focal length, an extension tube will reduce the minimum focusing distance to your subject.

Can I use this with the EOS R and the EF 100mm ...

Can I use this with the EOS R and the EF 100mm 2.8? As the lense is already adapted to the camera.
Asked by: Humaam
I need to qualify my last response. If you place the Extension tube between the EF 100mm and the RF adaptor (that you already have?) it might work. You say "as the lens is already adapted to the camera." Does that mean you already have an RF adaptor? My hesitation is that rear focus is so much closer on a mirrorless camera that adding an extension tube potentially creates a problem. The R series and the EOS with a mirror series are very different.
