L 20 Nikon Macro-- Wide angle ?

[Oleman]

I recently picked up a used L-20 and housing been playing with it in the pool and looks to be a good starter. My question is what about a wide angle do I need to buy one from the housing builder ? It cost more than the housing and camera or can I use something else. I will pick up a strobe before long and but want more info on a lens before I go to a dealer.
thanks for help

you can buy the ikelite lens but i would recommend going with inon. to attach it, you need to buy the ikelite adapter.
