Not sure how I feel about the specifications on this lens, two things are a concern for me. First and foremost the use of a stepper motor for autofocus, secondly the incredible light weight. The latter is of course great for carrying with less fatigue, but, it also suggests more plastic and less magnesium, this is a vicious circle, best build quality is great, more weight is not. Now there could be some carbon composites in the mix here and that would be a great middle ground, hard to know about that level of detail though.
People will argue that stepper motors are fine, well yes, but if they were so fine, why don't Nikon use them in the 400 f2.8. I feel at this price they should be using best in class motors for this lens and the 800f6.3 for that matter. It's probably just me, I always hope for best quality components
Does it really matter, well, it wont to most, but it does to me, frustrating more than anything.
Surely this will pave the way for the 200-600 specs, stepper motor drive again with more plastic and less magnesium, not sure that will make me happy, come on Nikon, prove me wrong please
Should be good for the market place in general, will surely give Sony and Canon a kick up the behind regarding their tele lenses.
