    Re: Need some help please!

    Effective f stop as you calculated is based on extension so it is the same as bellows extension. Using both would be double counting.

    Re: 4x5 field recommendation

    It does happen on 35mm, but generally there is enough coverage that you don't notice it except for light falloff in the corners when wide open. Lenses are lenses no matter what the format.

    Re: Nikon 90mm SW f8

    I'd hardly say it "clearly surpasses" as both lenses produce excellent images. The one thing the f/8 has overwhelmingly in it's favor is the smaller size and weight.
