Please be aware that this is not an E-mount. Petri EE AUTO 1.7/55mm aperture-less lens and Petri 2/50mm aperture-less lens with Petri-L39 adapter. PETRI C.C AUTO 55mm F1.8 Petri mount with L39 conversion adapter. If you prepare an L39-NEX adapter separately, you can use it with Sony cameras as shown in the image. The reason for being junk is that the 1.7 and 2 come with dedicated adapters, but the 1.7 cannot be used for long-distance shots. Close-up shots are possible as shown in the sample. For the 2, I recall that the aperture used to work and I could take pictures using the adapter, but when I tried to attach it for this listing, it wouldn't fit properly. Therefore, I couldn't take any pictures. I suspect there might be some accuracy issues with this adapter itself, and it requires some skill to attach. You should be able to understand if you look closely at the structure, so please refrain from purchasing if you are unsure. For the 1.8, you can take pictures normally if you prepare an L39 NEX mount separately. However, there are strength issues because the mount part is made with a 3D printer. I prepared an adapter specifically for this lens and used it attached permanently. All three lenses may have some dust and some scratches, but I don't think there is any fungus. I will answer any questions you may have to the best of my knowledge. Please ask. This is the product. I cannot provide support, so I am looking for buyers with knowledge. Returns are not accepted. Thank you for your understanding. Size... α E-mount
