Converting a Nikon non-AI lens to AI-S can be a great way to breathe new life into older lenses and make them compatible with modern Nikon camera bodies. While this process may seem daunting at first, with the right tools and guidance, it can be a rewarding and cost-effective way to expand your lens collection. In this article, I will walk you through the steps to convert a non-AI lens to AI-S format, so you can get the most out of your vintage lenses.
1. Gather the necessary tools and materials:
Before you begin the conversion process, make sure you have the following tools and materials on hand:
– A set of precision screwdrivers
– Needle-nose pliers
– A lens spanner wrench
– AI-S aperture ring
– Epoxy glue or similar adhesive
– Rubbing alcohol and cleaning cloths
2. Disassemble the lens:
The first step in the conversion process is to carefully disassemble the lens. Using the precision screwdrivers and needle-nose pliers, carefully remove the screws and other components that hold the lens together. Take your time and keep track of the parts you remove to avoid losing anything important. Once the lens is disassembled, clean the glass elements and any other components using rubbing alcohol and a cleaning cloth.
3. Modify the aperture ring:
Next, you will need to modify the lens’ aperture ring to make it compatible with AI-S cameras. Carefully remove the existing aperture ring and replace it with the AI-S aperture ring that you have obtained. Use the lens spanner wrench to adjust the aperture ring to the correct position, and secure it in place using epoxy glue or a similar adhesive. Allow the glue to dry completely before reassembling the lens.
4. Reassemble the lens:
Once the aperture ring has been modified and secured, carefully reassemble the lens, making sure to align and tighten all components properly. Double-check that the aperture and focus mechanisms are functioning smoothly before proceeding to the next step.
5. Test the converted lens:
Before using the converted lens with your Nikon camera, it’s important to test it to ensure that it is working properly. Mount the lens on your camera body and test its functionality, including the aperture, focus, and overall image quality. Make any necessary adjustments or repairs before putting the lens to regular use.
By following these steps, you can successfully convert a non-AI lens to AI-S format and enjoy the benefits of using vintage lenses with modern Nikon camera bodies. Converting lenses can be a rewarding process that allows you to expand your photography capabilities while preserving and repurposing classic equipment. Just remember to work carefully and patiently, and don’t hesitate to seek professional assistance if you encounter any difficulties.
