Help with Nikon to Konica Adapter! How do you use it?!? : LUSENET : Konica 35mm SLRs : One Thread

Gez, I feel real dumb asking this. But I spent all this money on a Nikon to Konica lens adapter and I can get it to mount properly on my Konica T3, but I cannot get a Nikon lens to mount onto the adapter. haha.

I tried 2 Nikon lenses to mount: A 50mm f1.8 AF and a 80-200mm f2.8 AF lens.

What am I doing wrong?

Help with Nikon to Konica Adapter

The AF lenses DO NOT MOUNT on the adapter - only the lenses from the same era (Before auto focus).

Noooo! You gotta be joking!

Hi Lee,

You have to be joking! Don't tell me this, gez, this was an expensive purchase to use my Nikon lenses on my Konica body.

Are you sure? The Nikon Bayonet F mount hasn't changed since it was introduced, I can still use AI or AI-S lenses on my Nikon AF camera. Just not Non-Ai, but that isn't because they won't mount at all, it is (from what I understand) a prong that is in the way on that model.

Thanks for the responce, I just don't know what to say. I was hoping I could of used my Nikon lenses. :(

Nikon to Konica Adaptor

Mike, Your problem is using those cheap Nikon lenses when you should be using quality optics from Konica.:-) Actually, you're supposition that the lens mount, per se, hasn't changed is correct. The only thing that was lost was the nonsense of indexing the maximum aperture with the meter. Now, to the problem at hand, I am at somewhat of a loss as to why your Nikon lenses don't mount. If anything, they should be easier to mount on the adaptor than on a regular Nikon body, since there is no linkage to the body outside of the mount. Do the lugs of the mount line up with the adaptor? Are you having trouble getting the aperture and focussing scales to end up on top? Please specify the trouble. Is the adaptor marked for Nikon to Konica? If not, it may be for Exakta mount, which is kinda close but no cigar. Please state the exact problem and maybe we can figure something out. This is most unusual.

Here is the problem I'm experiencing:

Hi Jon and Lee,

Well, here is the problem I am having:

The Nikon adapter fits the lens mount, but you cannot turn it to screw (or lock into place) the lens. You can turn the lens or the adapter about 5mm (1/4 inch) then it won't turn anymore. I have tried the lens/adapter in all the positions it could fit into it in but to no luck. I have also tried 3 different lenses now for the Nikon (all AF lenses) but none fit.

I am pretty sure (about 90%) the lens mount hasn't changed any, after all, you can use a AF lens on a Nikon F from the 60's and a 25 year old AI lens on today's nikon.

The adapter reads: Konica Nikon Lens Adapter AR and The Box reads: Konica Nikon lens mount adapter AR.

The adapter looks exactly like the one pictured here:

I don't know what the little metal piece on the side does, I have tried "doing" things with it but it didn't help or I wasn't using it properly.

Anything else?

Nikon Adaptor

Mike, Well, boil me in sheep dip. Now I'm really stumped. If I remember correctly, the "switch" on the side of the adaptor should be slid down while mounting or unmounting the lens. It's not an infinity stop as on the Exakta adaptor as I recall, but, rather, a catch to keep the lens in the mount much like the one used on Konica bodies for which one holds in the button to dismount the lens and as used in Vivitar extension tubes to unlock the lens to disengage it. Try pushing or sliding the "switch" while mounting the lens while the adaptor is mounted on the camera. This may give your finger the proper torque and position to engage this thing. However, I can't imagine Konica not making it capable of locking automatically. Or perhaps the locking mechanism is broken and preventing seating of the lens. From this point on, all I can give you is conjecture. Sorry.

What I have heard far...

The original owner of the Nikon to Konica adapter has told me that he only had Non-Ai Nikon lenses, that worked fine on the adapter. Maybe the Nikon to Konica adapter works only with Non-Ai Nikon Lenses? The Newer AF mount Nikon lenses don't seem to fit on the adapter...

Any thoughts?

Some interesting information I was told about the Nikon to Konica adapter...

I all, don't know if this is true or not, but I thought I would post it here to help others in the future as well on this Nikon to Konica adapter question:

"AI and AI-S lenses should fit just fine. They're nearly identical to non-AI lenses except that they have a portion of the aperture ring cut out, in effect, to provide the AI coupling.

The AF lenses have an additional little bit of space taken up by the CPU contacts. If they are coming into contact with something on the adapter, that could prevent mounting. They ought to fit, but I wouldn't force them unless you're willing to risk destroying those contacts."

Nikon to Konica Adaptor

Mike, Go to "Bodies" on this web site. Scroll down to Wulff for comments on the adaptor and which Nikon lenses he used. You could email him and see if would offer any other info. Good Luck, Dave
