Next year my Grandfather will celebrate his 90th birthday, the year after my grandmother will celebrate the same. In between these two parties they will celebrate their 70th wedding anniversary. I want to produce a collection of portraits of every immediate family member (~55) to give to them hopefully at their anniversary. The project could take the best part of a year, I'll like to start this summer. My idea is to produce sort of semi-formal portraits, heads and shoulders, using natural light or maybe a weak flash to bring out the eyes, with the subject at home. I want this to be relaxed and I won't be using studio flash, backgrounds or reflectors. I'll probably shoot indoors with light coming from a window, rooms will probably be small, so I won't be able to stand very far away from the subject. Film will probably be ASA400 optically printed to 10x8. What lens to use? I have two bodies: Nikon FM2 Leica M4-P I'll probably sell the lens after the project as I rarely do this sort of thing. Please let me know your suggestions. One word - I cannot afford four figure Leica lenses even if I will sell them on with minimal loss. Thanks!
