Do these have electrical connections so that you can set your aperture from the camera?

Dear Steve,I bought these and they have all contacts. Good quality. Recommended.No problem with lens recognition. Just make sure that the adapter clicks in position.Regards/ Gunnar in Sweden

They do, and the set seems to be made well (metal), but I found the results to be inconsistent. The lens doesn't always get recognized from the camera when using these extension tubes. I know the Kenkos are more expensive, but I understand they work very well, compared to these. These obviously work great if I stay in manual mode. Regards. Bill in Colorado.

Auto fosus and auto aperture require that the camera has to be able to control a motor in the lens. If there is no electrical contact on the adapter, you get no automatic focus or aperture.

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, they are, but you have to get closer to an object first, so camera may use autofocus.

No. This is a wired system. They come with 60 feet of wire for each camera.

I don't know. The openings would have to be exact eg. Camera on/off buttons charge connection.

No they are powered camera's - you will have to have outside plugs (either existing or installed) - I had put 4 outlets where I knew I wanted to put the camera's prior to their arrival. Indoor would have been easier of course - but I wanted mine for outdoor monitoring of the 4 exits/entrances to my residence. That is something that you will have to either do yourself (for outside) - or pay an electrician to have outdoor GFI plugs put in.

Not entirely sure when you say doors it need power? Or is a digital camera so power is needed. But you can manually change focus if that is what you need. Buy if you want to change aperture using a physical dial in lens then no it does not have it

No, only by wires. Great camera though, really good images. Worth the money.

No. Just wires to hook up as you like. These panels were for gate openers so they don't have any connectors attached.

Yes. The "M" setting on the dial allows you to set ISO, aperture, shutter, etc. manually.

Yes they do. However, wight he chest harness you will also need a "J" connector. The "J" connector connects the camera tot he harness and gives you the ability to move the camera angle down and up.

They are just lights. What camera you use does not matter. They do need to be plugged into an outlet.

yes, but really best used with older Nikon lenses w/ manual aperture ring. also there are no electronic connections between the lens and camera body.
653373
Yes, there are. You may need a converter to plug into your camera. I had to get one however they are only a few dollars.

This one will NOT work with a lens without an aperture ring. There are no mechanical or electrical connections in this extension tube set.
