Cooke optics XVa convertible ?!
any experience with the Cooke XVa ?
maybe even some samples that somehow show the way it renders.
characteristics and unique things compared to normal schnieder.
i suppose u should be able to focus this lens (normal 311mm) a little bellow 1 meter (90cm, 3 foot) with bellow extension of about 50 cm ? am i right ?
from cooke-optics website, i also understand that when working with 476 (back cell only), it needs far greater bellow draw (542mm) than normally expected, so, how close can u get with say 65-70 cm bellow extension ?
