SIGMA 135-400mm 1:4.5-5.6 APO This is a super-telephoto lens for PENTAX, rarely seen on the used market. It can shoot up to 600mm equivalent on a full-frame camera. There are some scratches and dirt from use, but I don't think any of them affect the photos. Operation has been confirmed. AF also works. Lens hood, tripod collar, and case included. I plan to continue using it if it doesn't sell. Please refrain from purchasing if you are nervous about it being a used item. If you would like to see this area in more detail, etc., I can take additional photos, so please feel free to comment. I've also attached photos taken with the telephoto lens. #PENTAX #SIGMA #SuperTelephoto #SLR #TelephotoLens
