Can the iris be manually adjusted at all? And if so, can you use this with an adapter on a camera that doesn't support auto iris?

No! Only the Focus can be manually adjusted. The "Iris" and or Aperture leaves are electronically controlled only..

Go to Setup > Release w/o lens and make it enable. It will definitely work.......

Mechanically the adapter should mount the lens to the camera, however there will be no electrical connections and you will have to set the lens manually.

Dear John;I am going to modify my statement slightly. I have four different cameras and buy a great amount of attachments for them and may have bought the adapters separately. I frequently switch eye pieces etc from one to another I do not want to worry about if it is the exact one for the camera and so have many adapters for a verity of attachments.I still believe you will not have any problem.Randy

As it was said any times in the customer's reviews (including mine), the adaptor does not fit perfectly and you have to do a few tries before getting used to it. The main point is to put the lens aperture control finger on the good side of the adaptor aperture control pin to allow the aperture control dial to rotate. If it does not rotate, you are on the wrong side. Hope this will help. Richard.

It will work manually but does not have an automatic mode. Also you will need an adaptor ring for it to mount to the camera body. These takumar 50mm lenses are definatly worth it. Hope this helps.

It won't work well, you need a full manual lens with aperture ring to use it in this adapter (in any adapter I think) otherwhise you won't be able to control the aperture and it will stay at F/22.You need something like this: http://www.amazon.co.uk/dp/B0000BVDZC

When I received this lens, it came with the Nikon adaptor, so be sure before you add an adaptor about what's included. Keep in mind that this is a manual focus lens with a fixed f-stop, so you will need to set your camera on aperture priority and the camera will adjust the shutter speed. Autofocus and automatic metering won't work as it does with Nikon lenses.

you can manually adjust, but make sure it works well I have been having so many issues since I bought it. I haven't been able to get it resolve by the seller, Amazon, or Samsung. Just be careful.

Hello, If the adapter allows you to mount the lens to the camera it will work but, you may have to focus manually. I am not familiar with your camera model so, check the owners manual about whether or not it will be able to use autofocus. Great lens by the way. I really liked it when I had my Pentax.

When I went from AE-1 to Digital Rebel, I was not able to use the old lenses. When I went from the Rebel to the mirrorless, I'm able to use the lenses with the adapter.

I believe that it can be adjusted. I love the camera but don't mess with a lot of the functions...I wish I knew a lot more about cameras.

Yes Works flawlesslyI use this with iris. Also if you go into MAGIC set up you will see the icon for the kwikset locks allowing proper configuration.

Assuming your manual lens has an f-stop setting, the iris is actuated when the f-stop is set, and it does not change when the shutter is triggered. This is in contrast to an automatic lens which only stops down during the exposure. On the NEX, the video feed for the LCD screen adjusts its sensitivity to compensate.

You can't use autofocus. These adapters are basically designed so that you can use the lovely AI and AI-S manual Nikon lenses on the modern EOS bodies. You can use them in aperture priority mode, too (where you set the aperture, and the camera sets the rest). But the other program modes that rely on setting the aperture automatically won't work.

One of mine became stuck on the lens and I worked it loose using slow but firm pressure. With the lens still attached to the adapter, you might have a little more leverage. A camera repair person might anchor the camera in a vice and dislodge the adapter with a screw driver and hammer...but VERY, VERY carefully. It's not something I would try unless you are really comfortable around tools. Wish I could be of more help.

Sorry I just saw the incoming email. Let me understand first. Are you saying that there is no way to do an "autof" on your camera with the lens? Try half way press the shutter see if the focus can be achieved.
