17-55 2.8 Aperture Blades?

Discussion in 'Lens Lust' started by Houndog, Jul 23, 2007.

  1. When researching the 17-55 I noticed is that some places (including Nikon USA) the specifications list the lens as having 7 aperture blades and some list it as having 9 aperture blades. Were there different versions or bad information?

    As long as I know, they are all 9 aperture blades.

    I doubt there are different versions. As far as I know all are made with 9 rounded aperture blades - all other f2.8 zooms from Nikon are the same.
     
  4. Not exactly . . .

    Mostly true--but, IIRC, the 20-35/2.8 has 9 straight blades, and the 35-70/2.8 has 7 rounded blades, and those are just two examples off the top of my head. I could be wrong though--it's been known to happen on occasion ;)

    Ok, so I should have qualified that by saying all current f2.8 zooms have 9 rounded blades. In fact most recent telephoto zooms such as the 70-300VR are the same, along with all telephoto primes since around 1990 (the AF 85/1.8 and 180/2.8 are the only holdouts with 9 straight blades).
     
  6. 17-55/2.8 has 9 blades

    Just counted the blades on mine = 9 :smile:
     
  7. Well it seems they do have 9, interesting that Nikon and some retailers list it as having 7.

    Thanks for the replies.

    Same with the 55-200mm VR, Nikon USA lists it at 7 while Nikon Global lists it as 9.
     
  9. Still only almost right . . .

    The 35-70/2.8 is still on the current products listing (for example: http://www.nikonusa.com/template.php?cat=1&grp=5), and I saw one on a retail store shelf last week so . . . still not quite right. Almost though--don't you hate nitpickers? ;)

    Are Nikon still making the 35-70?
     
  11. Well, they still list it in their current products . . .

    . . . and they're available to buy:

    I have no idea if they're manufacturing them still or not though. Still hard to say the 35-70/2.8D isn't a current f/2.8 zoom--it sure looks like one to me.

    Nikon Japan states 7 rounded blades for the 55-200VR, and 9 rounded blades for the older non-VR 55-200.

    There's always one which gets away... As far as I know this lens has not been discontinued, not sure if that means it's still in production. Maybe Nikon is still producing small numbers for those who want a cheaper alternative to the AFS 28-70/2.8. Same goes for the AF 80-200/2.8 ED. This lens does have 9 aperture blades, but the are not rounded :smile:
