Lens hood of lens for 12x20 format

[Johnny Eng]

I am going to buy Lee filter lens hood to fit G-Claron 355mm/9 and Nikor-M 450mm/f9. Someone told me that it would be better to buy Lee wide angle hood with filter slot because I shoot B&W.

I think I may need adaptor rings to fit the above two lens with the wide angle hood.

What are the sizes of adaptor that I have to buy?

Thanks in advance.

I'm not sure of the adapter sizes, but I agree with the recomendation for the wide lens shade. Be sure to get the wide angle version of the adapter.

You will need a 67mm adaptor ring for the 450 and a 77mm for the G Claron. As mentioned make sure you get the wide angle adaptor rings.
