That "adjustment" looks pretty complex to me and I don't find it listed in the camera manuals so evidently the manufacturers don't expect it to be necessary.  Once you get it calibrated on one...

How difficult is this calibration?  Is it something you would do if you used multiple bodies and had to switch back and forth?  If so, it almost seems as if the manufacturers have found a way to...

My brother has been a professional photographer for 40 years and I an amateur for 50 years.  I asked him the other day if he ever had to calibrate a lens.  Of course he said no which is my...

Did I ask a stupid question or am I the only one to buy this lens?

I have been extremely happy with the quality of my photos with the above lens.  None of the 300 mm telephoto zooms are rated very well and I can't afford the 400mm versions so I am thinking about...

I thought about it when I got the D7100 and decided instead to get the 40 mm macro and use it for a "normal" lens.  I don't do that much low light photography where the 1.8 makes that much...

I have read great reviews regarding the 18-200 but don't have one myself.  I bought a 7100 and the only lens I got with it was the 40 mm macro which doubles as a normal lens.  I love making...

I bought the Nikon basically for weight.  I traded in my 80-200 2.8.  What a difference to use.  I can actually hand hold it and the VR takes care of my shaky hands.  I've never seen the Tamron but...

I don't see any  discounts on the American pages.  Perhaps you are looking at another branch of Amazon.

Has anyone tried to use the Vanguard GH-300T tripod head with a D600?  No instructions come with the head and two wires are included to attach the head to Canon or Nikon.  You are supposed to be...

I paid $500 for mine so perhaps that was a bit much based on your letter.  I am older and my hands are shaky.  I consider the lens a tripod lens only.  I can watch the subject bouncing around in...

When I bought my 600 i let the salesperson talk me into the 50mm Sigma 1.4 which actually was a little more expensive than the equivalent Nikon.  I learned from my brother that the dealer makes a...

I have located the almost invisible numbers.  I guess my old eyes are giving out.  I knew in my heart they had to be somewhere.  Glad I'm not the only one who had trouble finding them.

I recently bought an 80-200 Nikkor AF, a 20mm 2.8, a 24mm 2.8, and a 35mm 2.0 and am having difficulty finding serial numbers.  The lenses are probalby 10-15 years old but are all AF and in good...

Looks good to me as far as photo quality and the setup at least looks like it will not fall off the mount.  Unfortunately I already bought one from Kirk Enterprises and invested well over $100 in...

Mine seems to be the earliest AF version and is really heavy.  I tried using it hand held and could literally see the scene jumping in the viewfinder due to my shaky hands.  I paid $500 for the...

Thank you for your reply.  I have unfortunately reached the age where hand holding a lens this heavy is not an option.  I know what you mean about hanging the lens from a camera mounted on a tripod...

Mine is definitely the early, screw on version.  I bought a bayonet after market shade and it won't go on the lens.  Thanks for the information.

Thank you.  The web site seems to identify my lens as the earliest AF.  Appearance is identical to the picture provided.  Apparently no tripod mount available.
