Non CPU lens on D7200

Scott, you are wrong. The contacts have nothing to do with the aperture.

[quote= I use older non cpu lenses on my d7100 al the time. Set it at the smallest aperture and go.[/quote]
I use older manual focus lenses almost daily on my D300, D7100 & D610. I just hauled out my D7100, set the aperture to the smallest opening (F32 on the manual focus macro lens from the mid 1980's that I had mounted) and tried to use the sub-command dial to control the aperture. It didn't work. In any of the modes on the mode dial... I suggest you do the same and you will see that I am correct...

The contacts have nothing to do with the aperture but lenses without contacts don't have CPU and all these lenses without CPU the camera can not set the aperture. You must use the aperture ring to set the aperture.

The contacts are for data transmission between the camera and the lens.

Scott, I'm not sure your comment is all-encompassing. I use several non-CPU Nikkor lenses on any of my DSLR. The aperture dial adjusts the aperture and the exposure is correct. The preview button also works, as well. On another side, some of my non-CPU lenses don't work with the aperture dial. I have to set the aperture using the dial on the lens.

I don't think the subdial can change the aperture on either camera as the lens has no CPU contacts to transmit the info to the camera... I use several non-cpu macro lenses on my D7100 and always use the aperture ring to change the aperture...

Which non-cpu lenses does the aperture dial work with? The preview button should work with any non-cpu lens as it simply stops down the aperture to the pre-selected one on the ring....

Scott, for one, my Nikkor 28~85 f/3.5-4.5. Another is my Nikkor 20mm f/2.8. Still, another is my Nikkor 135 f/2.8. I have another 135 f/2.8 that doesn't work with the aperture dial. Oddly, I have a Nikkor 43~86 that won't even mount to the camera. It works fine on my F, though.

I have used four non-CPU Nikkor manual focus lenses on both a D7100 and D850; images on the D850 are better than the D7100. Two things about those lenses, at least those I own and use, each lens must be added to the camera's menu and the correct lens selected when in use. The other thing I learned is that the camera itself has to be set to manual focus. In A or M mode, manually set the aperture and the camera will determine the shutter speed for that shot. In addition those older Nikkor manual focus lenses take some nice video.

The curious thing about a Nikkor manual focus 28mm f/2.8 mounted on a D850.....the lens is dwarfed by the camera body, looks almost out of place. I have used that lens for night shots in the area of Navy Pier in Chicago.

Is your 28-85mm f/3.5-4.5 an AI lens or AF lens? The AF lens should work but you can't adjust the aperture of an AI or AI-S lens with the aperture dial. Only with the aperture ring.

Check the lens compatibility chart for the D7200. I damaged mine because I listened to somebody rather than checking the facts for myself.

I regularly set the aperture using the thumbwheel on all of my digitals when using non-CPU lenses.

I know it is not an AF lens. I have to focus manually. However, I can use the thumbwheel to set the aperture and that works very well. In fact, if I move the aperture ring to anything but the smallest opening, I get an error message and the camera won't take a photograph.

"each lens must be added to the camera's menu" - this is not completely correct. The lens needs to be added to the camera's menu if one wants that lens to be recorded in the EXIF data associated with any photos taken with that lens. Otherwise, the lens works fine, but the EXIF data is devoid of lens settings.

If you do not enter lens data for the MF lens, the aperture display is wrong and the matrix metering would also be wrong.
