I would never presume to speak for all women, but as an almost 57 year-old woman (so not of the "current generation") who grew up in a home of modest means, and who loves a bargain as much as anyone, I'll share my perspective: Regarding the 5D: just don't go there. Buy your sister a new camera. We're not talking a vintage camera for a collector. We're talking about your sister who'd like a DSLR. And, you already know that your sister would not want to receive a second hand camera, so why are you still thinking about it? (Are you thinking about what you'd want rather than what your sister would like?) If for no other reason, you should give her a new camera so it will have a warranty. If the 5D breaks down, she'll have nothing. OK, I guess even broken cameras can be sold for parts, but she's still out a camera. If she asked you what SHE should BUY, then you could suggest a second hand camera. Or if she had hinted she wanted a 5D. But, you're giving her a surprise gift. And, in this case, I personally think giving your sister a used camera would be a really really bad surprise. In answer to your question about how I'd feel if I knew nothing about cameras and got a used one: To put it bluntly, I'd be WTF? I know they say it's the thought that counts but I'd likely interpret your thinking as strange at best. And, that would be in a calm moment of reflection after I had privately burst into tears. By your own statements, you've pretty much said the 5D is aligned with your preferences, not your sister's. Such a gift would not show that your valued your sister or her preferences. (To be clear, I'm not saying all second hand surprise gifts are wrong--some may be treasured--it all depends on the circumstances and I'm going on the circumstances as described by the OP.) Some final thoughts: if you want to make this about what your sister would like, then make sure you can return the camera for something else if it proves to be bigger or heavier than she expected or not ergonomically a good fit. Giving your sister a DSLR is a very thoughtful and generous gift. And, I commend you for being so generous. I just don't want you to mess it up.
