Q: 4. Does this work with a Canon EOS film SLR?

A: It does _not_ work on a EOS 500 or EOS 600 camera. Canon changed the EF mount data link protocol several times to exclude Sigma and other compatible lenses. It seems like the YN 50mm does not communicate with the oldest protocols. If someone knows of a list of EOS film cameras that work with the YN 50mm please post it. It works perfectly well on a 5DMkII.

Q: 5. Will this work good for Nikon D3400?

A: Yes, it should. It is a nikon F mount.

Q: 6. Does this lens have image stabilization?

A: No it does not have image stabilization. To be honest do not buy this lens. Pay more money and get a canon or nikon 50mm. More sturdier and quality. I bought the yongnuo mainly because of price and some had good reviews. It is very flimsy and bad quality made. It cannot hanfle the roughness or slight knocks. Image quality is ok. I had this lens for 3 months until the lens locked and didnt want to focus. It started to rattle. Although still under warranty the company wanted me to also pay for shipping. That was probably going to cost as much as the lens it self ( im from Australia). So save your money and buy local (so if anything goes wrong you are not far from the shop) and buy canon or nikon.CheersBelinda
