Wide Angle lens for D5

[Laurie O]

I know that Konica Minolta was bought out by Sony not too long ago - question: I have the Konica Minolta Maxxum D5, can anyone recommend a wide angle that's compatible with the Maxxum D5?

Also, I know that the hot shoe flash is proprietary, any ideas as to what flash will work on this particular camera?

Thanks in advance, I'm a total novice and this is my first time posting.

appreciate the assistance.
