EF Extender doesn't seem to increase zoom on EOS R6 Mark II with EF 70-200 L

[gokelgo2]

So my dad was shooting with an EF Extender on his R6 mII. He has his adapter-extender-EF 70-200mm L series (not sure on the specifics but shouldn’t matter at this point.)

Shooting raw, but it doesn’t seem like the Extender was actually doing anything to increase the zoom.

Are we doing something wrong?

That is very true further clarification would be needed. It also could be entirely possible that they're using an extension tube. Which is NOT the same as a teleconverter.

[deebatman316]

That could be true too. But without further clarification or a picture of the setup we don't know what they're exactly using. I'm also pretty sure that you can't mount an RF extension tube to the EF-RF Mount adapter.

I don’t use extension tubes. Would the image look normal if they weren’t doing macro shots?

[deebatman316]

Extension tubes make the lens sit further from the image sensor. This also comes at some costs like losing the ability to focus to infinity. It will also magnify the size of an image too but also reduce the depth of field of the image. Also it reduces the amount of light entering the camera.

Understand. Just wondering if OP was focusing on something say 50 feet away with lens and then added the “device “. Would it look completely different or just not enlarged?

[deebatman316]

I think that's what they were going for. Some people think a teleconverter can make their already short lens even longer. But not every case an extender can help with that instead they need a longer more appropriate lens.

New thought. 

OP has EF optics. If he switched from a crop sensor DSLR to the R6 that could explain what he is experiencing. 

[deebatman316]

Yes I was thinking of that too. There last camera was a crop body. But the new one is Full Frame so they don’t get the same angle of view.

Everyone is enjoying talking and speculating around the OP. Unless he/she rejoins the conversation, we're talking to the wind. Let's see what happens before wasting any more on this.
