Are there electrical contacts so that you can change aperture with the extension tubes attached?

Hello Kathryn, yes this extension tube supports automatic features. focus and aperture can be controlled through the camera.

Yes there are. My problem was being unable to mount the lens to one of the pieces at all, and the other two went on with a lot of resistance.

Yes, you have full camera function. Exposure and focus function is normal. When mounting on the camera it is possible to turn past the proper alignment of electrical contacts and if so the aperature will not work, just dont turn past the correct alignment.

Yes! These tubes work really well. You can change aperture and auto focus with these tubes.

Yes, this version has electrical contacts. It works perfectly. Cheaper versions maybe don't have.

These tubes have no internal adjustments or circuitry or anything like that. Once you put them on you have to set the camera to be completely manual, both mode and focus. I use these on a D100 and it fusses about settings until I set everything on manual and then it works.

You could modify the contacts to work with any drill, wires are your friend but then.... will the drill be comfortable or convnenient? That's the tricky part. I had one I glued on after I blue wired it and also ran some special wires to the modified charger... Not for that exact drill but a different brand so YMMV.

Without modification yes. You should be able to sure them to the same switch pretty easy though

Yes. The lens can be removed and interchanged with lenses of different focal strengths.

That is something I have not tried. Better to use a tube extension adapted to your camera

There are no electrical contacts in the ring so you have to adjust the focus and aperture manually.

Unfortunately no, not without some extensive modification. The holes for all the cams are already pre-drilled for the way it is shown in the picture. Changing it would be difficult.

If I remember correctly, none. You put what you want or use the crimp couplers to extend the wiring.

I do not know if you can buy the contacts.. but I would just open it back up, put the wire back in and solder it in using solder and a little plumbers type torch.

Nope. They do not have the electrical connectors for a motorized lens like those. Sorry this is only for the MD/MC mount style lenses

You could possibly buy the right size screws and modify the supplied adapters. I had to do that with mine but I used the old bar ends and made my own adapter. Also, even though they are small, you can see more behind and beside you. I have two of them on my FZ6-R and I feel it increased the visibility 10 fold. Actually view overlap directly behind me now where my factory mirrors were blocked by my body.

No. There are no connections to switch the windings. The plug is molded and fixed. Given the small size, I doubt separate motor windings are accessible, even if you opened it up.

Yes, they can. There is a round rod that connects the panel sections, so you can configure them different ways

Will need spade type connections. If one doesn't have them already, it's easy to change.

Yes, using the screw-open, screw-close ring you see in the picture. Otherwise, it probably wouldn't be possible.

You cannot use your existing mounting holes. You must make new ones so you can adjust them accordingly.
