Summary: Bad Quality Control - Nikon 24mm-70mm f2.8
Comment: According to other reviewers this is one of Nikon's best lenses ever. My first impression does not echo that sentiment. I just opened the box I received from Amazon and the first thing I noticed was that the zoom did not feel smooth and there was a sound of metal rubbing against metal when zooming from 24mm to 35mm. If the lens is rotated so that the focus switch is facing downward toward the ground, the metal grinding sound goes away, but the zoom operation still feels rough.
When zoomed wide the part of the lens that extends has excessive play, focus seems to work but there is something inside the lens that is not tightened down properly. This is a Pro series lens and for the price I expect better quality control than this. I have read other reviews reporting metal shavings and debris causing distortions. I am new to Nikon equipment, but so far I am not impressed with Nikon's quality control.
Since this is a quality control issue I am not rating the quality of the glass at this time, I have not had the time to fully test it and I don't want to waste my time with a defective product as my results may not be accurate. However, if a product can't be assembled reliably, with consistent results it cannot be rated as the best ever. I give this lens a 3 star rating because of bad quality control. An obvious defect as this should not have passed QC.
About Amazon Customer Service:
I understand that sometimes things go wrong, which is why we have "Customer Service". Amazon does not publish a customer service number to call and talk to a live person nor an email address to write to them. One is forced to go through their online return process with fixed and limited options. I requested a replacement and got an automated email response telling me to read the manual and contact the manufacturer, with a note saying: "Please note: this e-mail was sent from an address that cannot accept incoming e-mail." Aaaahhh! How frustrating!
I paid for expedited shipping and ended up with a defective product that I cannot use and Amazon tells me that any returns are at my cost. I usually purchase my camera equipment from a local camera store, B&H or Adorama who have real people in customer service that can rectify errors and replace parts.
Amazon gets a "1 Star" rating for customer service.
