This is a very nice set for your close up using basically any Nikon SLR lenses with 52mm filter thread.
1. Nice M2 extension ring
2. Nikon Close up No.1 in like new leather case
3. Nikon Close up No.2 in like new leather case (has some light wipe mark on the surface under strong light)
For example, you will have a close up function when you use your Nikon 50/1.4 with this extension. But you will not have AF function. Other lenses will do. Thanks!
Example, using this 5.8cm F1.4 Nikon first SLR standard lens on NEX3 (APS format), at nearest distance, without and with M2 extension. Sorry for the focusing and hand shake.
