Learn how to attach and use the TCL-X100 II tele conversion lens on your Fujifilm X100 series camera to extend focal length without losing image quality.

Quick Answer

Attach the TCL-X100 II tele conversion lens to your Fujifilm X100 series to instantly extend the fixed lens to a 50mm equivalent, giving you more reach for portraits and distant subjects while keeping the same sharpness and aperture.

Why Use a Tele Conversion Lens Instead of Cropping?

A tele conversion lens like the TCL-X100 II physically changes the focal length of the X100 series lens from 23mm (35mm equivalent) to about 33mm (50mm equivalent). This gives you a true telephoto perspective without reducing resolution or losing detail. Cropping in post-production discards pixels and can soften the image, especially with distant subjects.

The conversion lens also maintains the maximum aperture of f/2 on the X100 series, so you keep the same low-light performance and depth of field control. This is a key advantage over using a digital zoom or cropping.

Compatibility Check: Which X100 Models Work?

The TCL-X100 II is designed for the Fujifilm X100V, X100F, X100T, and X100S models. It does not fit the original X100 or the X100VI without an adapter ring. Always confirm your camera model before purchasing to avoid a mismatch.

If you own an X100VI, you will need the optional adapter ring (sold separately) to use the TCL-X100 II. Check your camera's lens thread size: the X100VI uses a 49mm thread, while the TCL-X100 II expects a 49mm filter thread on compatible models.

How to Attach and Use the TCL-X100 II Tele Conversion Lens

Step 1: Prepare the Camera and Lens: Turn off the camera to prevent accidental shutter or sensor movement. Remove the lens cap and any existing filter or hood from the X100 series lens. Clean the front lens element with a microfiber cloth if needed. A dirty lens can cause flare or softness; clean it before attaching the conversion lens.
Step 2: Align and Attach the Tele Conversion Lens: Hold the TCL-X100 II with the FUJIFILM logo facing up. Align the bayonet mount on the conversion lens with the bayonet ring on the X100 lens barrel. Gently press and rotate clockwise until it clicks into place. Do not force it. If the lens does not click easily, check alignment—forcing it can damage the bayonet mount.
Step 3: Enable Tele Conversion Mode in the Camera: Turn on the camera. Go to the shooting menu and select 'Tele Conversion Lens' (or 'Digital Teleconverter' on some models). Choose 'On' or 'Wide/Tele' depending on your model. This tells the camera to adjust the viewfinder frame lines and exposure metering for the converted focal length. Skipping this step may result in incorrect framing or metering—always enable the setting in the menu.
Step 4: Compose and Shoot: Use the viewfinder or LCD to frame your subject. The camera will now show the 50mm equivalent field of view. Focus as normal—the autofocus system works identically. Shoot at your desired aperture and shutter speed. Check that the viewfinder frame lines match the tele setting; if they look the same as before, you may have forgotten to enable the conversion mode.
Step 5: Remove and Store the Lens Properly: Turn off the camera before removal. Press the release button on the conversion lens (if applicable) or rotate counterclockwise to detach. Replace the lens cap on the camera and store the TCL-X100 II in its protective pouch or case to prevent scratches. Always store the conversion lens in a padded case—dropping it can misalign the optics.
