I just recieved an adaptor for nikon to canon eos. Only thing is their is a chip in the adaptor. I can't cahnge the aperature on the nikon manual lens. it just stays wide open. The camera is also reading the aperature at f2. I'm not sure why I cant get to 1.4 and also why changing the fstop on the lens not change the aperature in the camera.

Any ideas?

Probaly need to clean the aperature or oil it I'm guessing

With the Nikon lens, you should be able to change the f stop manually.
With the chipped adapter, it may say F4 in the camera, but you are using manual so that does not really matter.
There should be a sequence to do to make it adjustable.

I don't like the chipped adapters much as it can lock you in and not allow you to take a shot because it may think it is not in focus.
I would prefer to shoot and take the shot when I press the button, regardless of focus or not.

Just me.
 
If you dismount the Nikon Lens, there is a little blade thingy that you can toggle to snap the aperture open/closed. it should work fluidly and...be snappy.

The chip you mention is prob. just a focus confirmation chip, though it does depend on the adapter you chose. There are some newer adapters for the G lenses that do more, like aperture adjustment, but their $300 or so.

You say it's a MF nikon lens, if so, it has an aperture ring and you simply grab it and turn. Some rings have a lock on them to keep them at f/22 or what have you, so look for that too.
 
When I changed the fstop on the lens and look at it. The aperature doesn't close. It just stays wide open or almost wide open not sure. Don't have another lens that is as fast as 1.4. When I look at my nikon 24mm 2.8 and I close the apertaure and open it I can see the aperature blades closing and opening.
 
@Tom_Wise I will try the blade thingy tonight to see if that is the problem. Once I do that it should work to open and close the aperature (on the lens of course) right?
 
@Gonzo No. ITs an older AI lens.50-14-ai-KEN_0012.jpg. I called a lens repair he told me it would be 100 bucks to fix. Said it had something to do with oil. I'm still gonna check to see if their is a lock on it near the rear element.
 
Never got the hang of that... screw open the back & reverse the pin is another option... if you're like me, stubborn :)
 
Yep, that's a series E lens. Remove the front and rear caps. Stop the lens down to F22. On the rear of the lens, on the inner (black) barrel there's a piece of black metal that should slide back & forth. When you slide it, it should open the lens all the way; when you release it, it should "spring" back and the lens should close up. (This is so SLR cameras can focus and compose wide open - you wouldn't like doing that at F22 after all. When the shutter is tripped, that spring-mechanism lets the lens stop down to whatever stop you're shooting at, and then spring back open).

Series E lenses are cheap (hint - you can usually get a 50 AND an old film body for less than just a lens on eBay). You might hunt the web for repair how-to's.

By the way - the 100 2.8 series E is a monster. Gorgeous lens.
 
PS - for video, skip the chipped adapters - you only need a specialty adapter if you have a lens without an aperture ring. The $20 chinese deals work fine - the $70 fotodiox "no-play" are a bit tighter fit and worth the $$.
 
@Michael Carter Thanks man. I will do that when I get home from work. I apperciate your help. (and everyone else's also).
