FJP, I am looking forward for ur comparison... especially on the AF
speed and quality..
I just got the Sigma today. I commented on the pitiful way UPS
treated the external box on the D70 forum.
I'm at work so can't run any tests. I was very impressed by the
quality of the handsome green lens case that came with it. Sigma is
obviously trying to give a great first impression, and I certainly
didn't expect such a quality case to come with such an inexpensive
lens. Are you listening Nikon? Nikon, apparently, does not have to
compete, and only provides throw-aways with the DX lenses I've
bought from them so for (even the included 12-24 case is pretty
useless, at least for me). I'm sure the case that comes with the
17-55 DX lens will be a different story, although I haven't heard.
The lens itself is about the same weight and size as the Nikon
70-210mm f/4-5.6D, but the lens hood is bigger for some reason.
Maybe they want to be more conservative at the wide end. The front
lens cover is nothing special and I will undoubtedly replace it
with one of those very nice Tamron covers, which Nikon is now
imitating with the covers for the DX lenses.
The lens zooms smoothly out but is sticky zooming back in. Haven't
read the instructions yet but the markings on the lens barrel seem
cryptic and I didn't see any markings that suggested this lens went
down to 1:2 at 300mm.
The lens housing is plastic, but not offensively so. What do you
want for a couple hundred bucks?
That's about all I can tell you until I get home and can use it. I
probably won't have time to put it into action until sometime this
weekend.
