I noticed the Fotodiox does not have an aperture ring. How does one adjust aperture when using this adapter?

The lens itself must have manual aperture. I returned this.model for a.more.expensive one with five settings.

You need to eather use objectives with aperture ring or get an adaptor with a lever to control objective aperture. I like well builded, all metal, aperture ringed objectives, they feel great and give you full control, focusing, deph of field, exposure :)

Just like any other Nikon SLR lens, the G type should have a small tab on the camera end of the lens that allows the camera to control the aperture. The Fotodiox reverse lens kit that you're looking at comes with an adaptor to connect to the lens mount on the lens that allows you to adjust the aperture. Without this part, you can also adjust aperture by controlling the tab with your finger, but it's much more difficult.

You can save money and buy an adapter without aperture ring or you can buy this and use your aperture ring or the one on the adapter...it is up to you, the adapter will work in any case but if you don't need to use newer EF lens (without aperture ring), maybe you can go cheaper and buy an adapter without aperture ring (check on the B&H; website for the best option and then you can look on Ebay or Amazon for the best price...)

Most DX lenses are "G" designated and missing the aperture ring. This adapter does not carry any data from the lens to the camera. It also has no mechanical connection. Therefore, most DX lenses will be stuck at the smallest aperture and photos would be severely underexposed. With this adapter, you must focus and set your exposure manually. If your lens has an aperture ring and focus ring, this well-built adapter works fabulously. With focus peaking, manually focusing is a pretty quick and easy task. Keep in mind, the exif data will be missing info like aperture setting.

Im confused...so will the adapter ring allow me to attach actual camera lenses, for example, a fisheye or a 52 mm lens etc etc???

Depends on which OM lens you are talking about. I was unable to locate the compatibility chart on Fotodix's web site, and only one on my OM lenses would mount, so I returned the adapter. Give Fotodiox a call and see if your lens will work.

This adapter provides NO electrical connections betwen the camera body and the legacy lens. So there is no mechanism to focus the lens except your fingers :-) This is true for many of the inexpensive adapters, especially the early entries in the field. If you have any more specific questions, write to Fotodiox -- they were very responsive when I had a problem.

The rings are for different size lenses. Pick the one that fits the size of the lens. It screws on the end where the filter goes. There should be tiny threaded section for it to screw on to. Be careful not to get it cross threaded. Then the light ring slips on to the adaptor.

Hi! I use the Fotodiox adapter on a Sinar P and it fits fine. The plate is a little too thick so it will be easier to mount if you file the top and bottom of the plate down a millimeter or two. You will see what I mean when you get it. Be aware that it works best with longer lenses, 150mm and up.

None of my lenses have an aperture ring; aperture and aperture priority is controlled by the camera body. I own the 5300, not the D5100, but aperture priority is a pretty basic function, so I am sure the function exists in that camera body.

I use this adapter with lenses that already have aperture rings and it works just fine. You just need to keep the aperture on the adapter open all of the way. It might be beneficial to just go ahead and buy this adapter instead of a passive adapter in case you want to invest in newer canon glass.

Mount the lens on the adapter, mount the lens plus the adapter on you camera, focus the lens, set the f stop on the lens, set the shutter speed in your camera using the camera's meter or an external light meter, finally press the shutter. You may have to adjust the exposure slightly for the given scene. This is a fine adapter, well made and it works well, but unless you have an eos 5 series or eos 1 series full frame camera and a a few hasselblad lenses that you can't wait to saddle up then you should not bother. The s series lenses for the corp sensor cameras are very inexpensive and will yield a much more satisfactory experience.

As someone else mentioned, the blue ring on the adapter adjusts the aperture in your lens. If the lens that you're using has its own aperture ring, it's best to set the blue ring on the smallest circle and adjust the aperture using the lens ring. If you have the blue ring on the largest circle, the lens ring won't be able to close down.

Nikon and Pentax mounts do not have an aperture ring. Some functions may not work depending on the camera model.

Draz, this fotodiox adapter is not what you want. this adapts a lens with an M42 mount to be able to attach to the Canon EOS camera body. What you want is a nikon to EOS adapter. They are certainly on amazon, but it's not this adapter.

Yes. The aperture ring on the adapter isn't very precise, but it does work.

Fotodiox adapters are very good - I use Minolta and Leica M-mount (purists may cringe at putting a Leica M lens on the Nex but they work just great!
