How to care for the lens

tokyo grapher's dedicated iPhone attachment lenses are manufactured after conducting research, precision processing, and adjustments that are comparable to those of regular camera lenses in order to expand the possibilities of iPhone cameras.
The best attachment lenses that are particular about the original image quality and resolution of the iPhone are developed by combining optical glass of various materials and shapes for each product. In order to maximize its performance and use it for a long time, we recommend that you treat it as carefully as you would a single-lens reflex camera lens.
This time, I would like to talk about maintenance methods and tips to make the most of the power of tokyo grapher lenses and use them for a long time.

dirty lens

  • Clean lens
  • Lens smudged with fingerprints

If the photos you have taken are not resolved well and you feel that the lens may be broken, please check the front and back of the lens and the iPhone camera for any dirt.
In particular, it is necessary to pay attention to dirt on the back of the lens, which is often overlooked. If you take pictures with the back of the lens dirty, the pictures you take will be blurry and the resolution will not be correct. If there is dirt on the surface, use a blower to remove dust and dirt from the surface, wipe off any dirt with a lens cloth, and attach the lens to the mount.

Prevents white discoloration on glass lenses

If the lens is stored with water on it, the sodium ions contained in the glass will dissolve into the water, altering the quality of the glass, and further reacting with carbon dioxide and sodium will leave a cloudy white mark. . This phenomenon is called white discoloration on glass. This is the cause of white fogging on old window glass.

Until moisture adhering to the lens causes white discoloration

The water-repellent coating applied to the lens can be expected to have the effect of suppressing the occurrence of white discoloration. Doing so will lead to white discoloration. Frequent care is required because the part that has become white can only be removed by polishing.
After using the lens, use a blower to remove dirt and dust from the surface, and if there is water on the surface, be sure to wipe it off with a lens cloth. Also, if you do not use it for a long time, please avoid storing it in a hot and humid place. Best kept in a dry box.
