Well, I have 300/5.6. Barely covers 5x7, so quite a lot of room for movements in 4x5.
Not the sharpest lens in the pack tho, center is ok, edges fall a bit apart even on 4x5. But it certainly is lightweight (aluminium elements, 370g without shutter) and compact for the focal length and aperture. And pricewise it is much cheaper than, say Schneider tele-xenar 270, or alike, without compromising image quality that much.
Vignette on both images is caused by moderate tele shade, not by lens limits.
