Old Nikkor lenses are amazing, very well made and all have their own character. These lenses are still a joy to use on your DSLR and with this modification it gets even better

I will professionally modify the aperture ring for you.   You will now have full colour matrix metering and set the aperture by moving the aperture ring on the lens. Like you did in the pre digital age.

This high precision conversion is the only modification method available which is not visible on the outside of the aperture ring of the lens (as you can see on the pictures). 

For some Lens & Camera combinations this method is not suitable, however as you can see I have other options available. Please see the new TABLE I have added in the pictures.

Works for following Manual AI Focus lenses often with names including AUTO, followed by H, N, S, O, P or Q.

Examples are:

24mm 2.8 Nikon Nikkor auto N & N.C

35mm 1.4 Nikon Nikkor N

50mm 2. Nikon Nikkor H

55mm 3.5 Nikon Nikkor micro P

5.8cm 1.4 Nikon Nikkor S

85mm 1.8 Nikon Nikkor H

105mm 2.5Nikon Nikkor P & P.C

135mm 3.5Nikon Nikkor Q

200mm 4. Nikon Nikkor Q & Q.C

80-200mm 4.5 Nikon Nikkor

300 mm 4 Nikon Nikkor H

Other lenses: please ask as I have other superb solutions available. See new pictures

Customer will need to send the lens or aperture ring.

I will carry out this conversion myself and ship lens or aperture ring back to you.

Contact me before purchasing this service (please inform me about camera and lens serial number preferably)  If your lens is not displayed I possible can offer you another solution.

Please check your camera if it has the exposure meter coupling available. Currently on cameras like D300(s) D500, D610, D750, D7200, D800, D850, D5 and Df and even Nikon film cameras.

Once payment is cleared I will send postage instructions to you, upon receiving your lens I will modify the aperture ring which will be posted back to you within 5 days, second class signed for.

This method is not done by just filing the aperture ring or so called re-modelling. My technique is unique, proven and above all does not change the appearance of the lens. Arguably better looking than an Ais aperture ring.
