This question comes up a lot, so I wrote an article explaining all the issues and combinations. Here it is:
It turned out a lot bigger than I wanted, but this turns out to be kind of a messy issue. Anyhow, there it is, and I hope it's helpful.
If anyone sees any issues, or any improvements that could be made, please do let me know.
The link will also be so far down to be almost impossible to find. What difference that makes is lost on me. The message and/or link will not be at the top. If someone doesn't do a search for it they won't find it or the link. And, if they do do a search they probably would just do a search in google first.
I'm sorry I wasn't clear, so let me try to explain.
Many times people post questions here like "will lens X work on camera Y". A lot of times, I've seen people respond by typing in an answer manually, which seems like a lot of work.
But now, when someone posts that question, you, or I, or someone else, can respond by just pasting in the link to my article. Which seems like it would be less work.
Instead of typing in stuff abut flange distances and image circles and so on over and over again, I've typed it in once, in one permanent place, so people can just link to it.
The link won't be "so far down"; it will be the response to their question.
So, like I said, "Anytime someone posts the question, I (or someone) can post a link to the article."
Does that make sense?
