I don't know the answer to the question about using non-AI non-CPU lenses.

Nikon's manual does not address those lenses.

Perhaps you can contact Nikon's tech support to ask them directly.

I did send an email to Nikon Support. The following was their reply:

"Hi Brian,

See the following link for more information on using older lenses on your D50.

Title: What lenses can I use with the D100, D80, D70s, D70, or D50?
Thanks for using Nikon products! Nikon Inc. (USA) Support / Service
So I used the url they provided, but couldn't make out if these lenses could be used safely. I am new to all of this, and the info provided on the page seamed to be in a very strange language to me.... :-):(

So I am still wondering if they can be used safely on the D50.
It would sure safe me a couple of $$$$$ because I can borrow these lenses to practice, and then when I am ready for it purchased some other types of lenses (maybe 18-200VR) with the saved $$$$.

That's the same link I gave you in my last post to this thread. ;)

If you look at the other link I gave you (also on Nikon's support site), it shows you how to look at the lenses to try and determine if they are AI or not (and you don't want to try to mount non-AI lenses on your cameras as you can damage it).

I merged the two separate threads on this subject into one thread, since you're asking the same questions again.

It's unlikely that anyone will know by the serial numbers if your lenses are AI or not. If they do, they'll respond. Starting a new thread with the same questions isn't going to get faster or better responses. ;-)

You're probably going to need to *look* at them and see if they are AI or not. See the second link to Nikon's support site I gave you in my earlier post that has pictures of what to look for:


You should not attempt to mount a non-AI lens on your D50.

You can damage your camera if you try to mount them (you can bend the AI Coupling lever for one thing).

Even if you convert them to AI (which makes them safe to mount), you won't have any metering with a non-CPU lens on a D50.

Lens types that can and cannot be used on a D50

Here's an answer that may help you determine the lens types you have:

Differences between AI and non-AI Lenses

If they are not AI lenses, don't try to mount them (as you can damage your camera unless they're converted to AI).

Here are some more photos that may help you. If you click a smaller image, you'll get a bigger one:

Even more pictures that you may find helpful.

Another Hint....

If the lenses were manufactured before 1977 and haven't been modified, they are not AI (Nikon didn't introduce AI lenses until 1977), and they should not be used without converting them to AI (or you'll risk damage to the camera).

Thanks for the urls.

I have printed out the information and will check these lenses when I go home.
I will probably also post some pics of these lenses so that we all can take a look at them.

Thanks again.

With a little luck, they'll be AI.

But, keep in mind that you won't have metering with an older non-CPU lens on a D50, even if they are AI. Nikon doesn't turn on the meter with non-CPU lenses in it's entry level DSLR models (the least expensive current Nikon DSLR model that can meter with non-CPU AI lenses is the D200).

So, you'll be shooting "blind" (estimating the ISO speed, shutter speed and aperture combination needed) unless you have a separate light meter (or want to use another camera's meter) to help you out with settings. You'll find a lot of exposure charts around the net that can help with starting points for settings.

IOW, you can probably expect some trial and error for a given lighting condition to get the settings just right (and your histogram and playback features can help you see how your settings are working for any adjustments needed for a given shot). Shooting raw will give you a bit more exposure latitude for correction later, too (as long as you don't underexpose too much, or overexpose losing highlights).

Thanks for the responses everyone.

I have made a printout of all the urls you gave, but still get confused with what is said.

I also have made a couple of pictures of all of the lenses, but keep forgetting my USB stick at home. So I guess I will post them after the Christmas holidays. Hope you don't mind.

Before I forget, is there anything in particular of the lenses that you need to see??

Happy holidays to you and yours.

You might try looking up your lenses' serial numbers here--

to get an idea of their capabilities...

bedde Dec 22, 2006 11:19 AM

Hi Telecorder,

Thanks for the url.

According to the site the two Nikors are type K (New Nikkors, Late pre-Ai lenses (1974)) lenses. Does this mean they can be safely used on the D50 body??

Do you also have an url where I can find out if the Vivitar lenses can also be use safely on the D50 body??

Telecorder Dec 22, 2006 11:31 AM

Can't help on the Vivitar but you may want to read up on the Nikon versions at:

Can't/don't want to comment and confirm whether the lenses in question would be compatible with your D50. Usually, the issue is whether the lens will have an issue with a teleconverter due to the rear lens extending behind the lens body hitting against the front lens of the TC.

Mounting a lens onto the body usually has more to do with the communication or lack of between the lens and the body. I believe most all earlier Nikon lens will mount, though. I'd suggest posting your inquiry over at Nikonians...
