Does this pass power, etc to the lens or is this un-powered? I didn't see that noted in the specs

Yes, they have pins on each length of tube that allow a connection to your lens.

If I understand what you are asking it does allow the electronics from the camera to the lens. So your auto focus and aperture work normally. On my camera it works great.

It allows the automatic focus and aperature adjustments to work, just like a normal "automatic" lens. You may experience some "lag" and "stutter" in the auto-focus due to the drop-off in light passing through the lens. But, they will work.

Hello, the extension tubes pass all the automatic functions to the lenses..

I had the same problem and I found a fix on a different site, so I thought I'd put it up here, too. It seems the "access" message happens because the lens doesn't open all the way; not sure why that is. However, when my camera opens and says "access," all I have to do is get it all the way out. So: very VERY GENTLY pull on the end of the lens (away from the camera body). You can't even feel it move, really, but then it starts working again! Hope this helps.

Hi Shaun! The lens has no electric functions so it can't talk to the camera like more advanced/expensive/modern lenses do. If you can continue shooting you're good to go, you'll just have to adjust your iris and focus manually, as opposed to those functions being camera controlled. Most cameras should just let you say "okay" and keep shooting though. Have fun! The lens has a really unique and beautiful flare, so make sure you check that out. Cheers, Colin.

The power part of a power mirror is not in the morrow glass itself, it's in the actual lense holder, this has turn signal and that's it.

No electrical components at all. Any lens (Including autofocus lens) must be manually-focused.

There are many when used with a thread on 52mm Lens adapter available from most photo shops. You can put any 52mm lens or filter on that does not require power. I use `wide angle', `portrait', `zoom multiplier' lens and lots of different filters on mine. This camera works best with studio or otherwise good controlled lighting compared to point and shoot for really quality results. I personally use it most for shooting art for future limited edition print creations.Another benefit of this adapter is primary lens protection. When not using another "IN FRONT" mounted lens I leave on a UV filter to take the beatings time brings to you.

It is really hard to tell whether it is the adapter or the lens itself. The images I have taken so far are reasonably good. I am using Vemar and Mamiya lenses from my film days. If the old manual lenses you have are of good quality you are likely to get good images. There doesn't seem to be any drop off in light transmission. This adapter has a single, clear piece of glass in it so light loss, if any, should be minimal.

100% the zoom is always powered and very fast, no matter which lens you choose. The manual lens handling is way better than the powered version, but it doubles the size of the system. If you like full control over what you are doing stay away from the powered lens... it's awkward...

On all of the canons I have owned it works this way:There should be a rubber piece around the eyepiece. It usually slips off by pushing it up. Take that piece off and slip this lens in its place. You won't need the rubber piece anymore.

This is not a spotlight, the output is pretty uniform, and there are no visible "hot spots" in the lens. The lamp is supposed to be equivalent to 65 watts, but it appears brighter than that.

Short answer: yes. Generally always better to turn the OS on any lens off when using a tripod, if nothing else it uses less power that way.

had not had any issues with lens flair but I also try not to shoot in direct sunlight. lens is sharp despite what others have said. It's made for a full frame body...very happy with the lens performance....I recommend it.

I can't distinguish a decrease in battery power, but I have it so that it's in power saver mode. The eyepiece comes on when my eye is positioned in the viewfinder, otherwise it's not on.

Yes. it does so in mine also. I think it is when you turn it off or you deactivate the AF that the lens probably detaches something inside.

The adapter provides no electrical connection between the camera and the lens - the camera really thinks there's no lens attached! I have a Sony NEX-6, and I solved the problem (with help from another customer) by going to the camera's menu, selecting "Setup", then scrolling until I found "Release w/o Lens". Click on that option to enable it, and the camera will shoot. Of course, with the adapter there's no autofocus or aperture control - you have to do those on your own. But it works fine!

The power through the cable depends on the source, where you hook it up. It can be "switched" or "unswitched" meaning the power source is controlled by the ignition switch. Either way, if the camera is on, it will drain the battery, over time. Hope this helps.
