Great Product and Service
This is the second adapter I have purchased from K & F. The receipt time was great -- about 9 days from the time I ordered them. So far, both adapters have worked great with the lenses. Solid construction--too many of the others seemed to have flimsy release buttons and many had commented on that fact and that many also got stuck on the camera. And, it came via U S Postal Service which I loved as I am a 37 year veteran of the Postal Service. I knew my package would not be left next door or around the block as some of our competitors have done to me in the past.
