What the AI looks for in Darkroom Enlarger Accessories

Enlarging lens focal length: Use about 50mm for 35mm, about 80mm for 6x6 and 6x7, and about 135 to 150mm for 4x5. A shorter lens won't cover the negative evenly. A longer lens limits print size on a given column.
Lens mount: Most enlarging lenses use the 39mm screw thread (M39). Check that your lens board accepts it or buy the matching adapter board. Lens boards are specific to each enlarger, and the wrong board leaves the lens unmountable.
Negative carrier: Buy carriers made for your exact enlarger model and film format. Carriers aren't cross-compatible between brands, and a mismatched mask causes light leaks or a cropped image.
Contrast filtering: Use below-lens holders or above-lens filter drawers sized to your enlarger. You don't need them with a dichroic or variable-contrast head. Multigrade papers need filtration to change contrast, but below-lens filters slightly degrade the image.
Lens quality: Prefer six-element designs, such as Componon-S, Rodagon or El-Nikkor N, over basic three- and four-element lenses. Better lenses give corner-to-corner sharpness at moderate apertures.
Easel and focuser: Choose an easel with adjustable blades that won't shift, plus a grain focuser for critical focus. Square borders and grain-sharp focus separate clean prints from soft, uneven ones.

It can work in a pinch, but enlarging lenses are corrected for flat field at close distances, so they give sharper, more even prints.
