Thank you for your inputs. Very helpful.

Looking for a recommendation for a 200-500 lens to complement my Nikkor 70-200. Camera is a Nikon D750. Someone told me that the Nikkor 5.6 would not work compatibility with the D750 which sounds strange to me.

Most are 4x6 format. Negatives are hit and miss.

Would like recommendations for a good scanner that has bulk feeding. I have 25 years of photographs, mostly family and 4X6 size. I have a good flatbed scanner but too time consuming to handle this volume. Thanks for your inputs.
