I tend to loan gear out more so than give it away, as I figure why let a friend do without something they could use while it otherwise sits on a shelf taking up space and collecting dust? Sometimes it is a lens to someone while out at the same area just so they can try it out, others it is a complete camera and gear bag sent along with them and ending up staying with them for years. (Mostly because it was something I didn't really use because I had since upgraded to gear I liked more anyway, and keep forgetting that technically it is still mine.)
I have given out maybe three rolls of film to people in the last year, developed film for someone once or twice, have offered the use of my daylight tanks and other equipment to someone who is thinking of getting into film work, and awhile back I traded a roll of Delta 100 to someone I met randomly in the park in exchange for a roll of TMax simply because they mentioned they were curious about how the Ilford film would work for them.
