It's amusing that photographers with the level of experience described here are either; puzzled that the appearance of moire in a DB fabric shot appears in the first place, or that it's still viewed as a difficult thing to remove, or worse, viewed as 'for the money this camera should never have moire', which is an eye-roller.... Take this crap Ferrari back, it won't do offroad...
We all know there are design limitations, physics limitations and specialization decisions made on every piece of photo gear, in the case of MF it's meant to default to ultimate image quality at the increased chance of moire. If you want what a good MF does, your no-buffered exposure will mean some degree of moire as a consequence of that build - which we are all hopefully aware of by now.
Personally I'd rather have the sometime moire challenge and enjoy the many benefits that MF brings to my particular type of work and process, it's no contest for me.
Thankfully a simple Lab conversion and total moire correction takes minutes or less. As well there are other techniques and software which can take care of the problem to a greater or lesser extent.
Yanick if I were you I'd be more concerned with the potential for increased retouching time overall, the difference in skin resolution alone may make you think twice, I guess it all depends on whether you want to really have best possible fashion images, or 'good enough' fashion images. Here is an early Christmas present, go buy 'The Canyon Conundrum' and read the chapter on moire.
Personally I believe that when we settle on good enough images in any way you want to interpret that remark, that's when we have plateaued, or given up.
