FS:Raynox DCR-250 Macro attachment
To answer your question yes you can with a bit of patience, but it is verry tight.
Seller gives an extra step down ring where you will not use the manufacturer suplied adapter but the step down ring that will make it much more easier to install it on lens with 49mm thread

It does indeed fit easily and neatly on 49mm with the step down ring.

Still for sale
