I love the 24 (D version) on my film camera! The recommended hood is very nice, sturdy aluminum. If you use a different hood, even on a DSLR, you may cause vignetting. With the HN-1 hood, you may want to get a 72mm cap, as the 52mm can be difficult to get on. On a D70, the CA can be visible in high contrast subjects. A while back I shot an event where a black and white checkered sign was in the frame, and could clearly see the CA along the edges. It usually appears as blue on the left, red on the right. Try taking a shot of something with crisp black/white edges. You should be able to see it. That said, I still love the lens. It's sharp, well built and handles well. For the type of shooting I do, it's wonderful. I haven't come across the flare problem, but I rarely shoot backlit subjects. I'm hoping my love for it doesn't fade when I spend significant time using it on a DSLR.
No photograph is worth endangering the wellfare of the subject
