Pentax K1000 Prism Replacement Part. This will suit any generation Pentax K1000 (Japanese/Hong Kong/Chinese made). Sick of that black blob in the middle of your K1000 viewfinder? This is actually prism de-silvering. It makes it difficult to frame your subject when shooting, and once it appears, it will only get worse. Note: Image may slighter differ to item delivery, don’t worry, it will still fit. This is a non-genuine Pentax part - use the existing tension springs and screws in your existing camera. Installation not included. If you are local to Sydney and need this part installed, feel free to contact me. Nick’s Picks Australia Support local!
