K&F M17111 Pentax K Lenses to Fuji X Lens Mount Adapter
Super tight fit on X-T3
The K-mount side fits my Sigma brand lens just fine but the X-mount side is super, super tight. I can\'t even get the adapter to twist on all the way. Maybe it goes 2/3 on. I\'m not going to force it. Even 2/3 on it\'s not coming off too easily. I would try another brand.
