The PENTAX KX combined with a SIGMA zoom lens is a great setup for experiencing the appeal of a film SLR camera. - Brand: PENTAX - Model: KX - Lens: SIGMA zoom lens - Lens diameter: Approximately 62mm - Mount type: K-mount Operation has been confirmed. The exposure meter has not been tested and is likely not working. I usually used an app to measure exposure, so I trust the app more. It has a mechanical shutter, so it should last a long time. Thank you for looking. Negotiations are welcome.
