Hi Kyle,

The main difference is in the range of the chromatic aberration corrections. Chromatic aberration is the inability of a lens to focus light of different wavelengths to the same convergence point.
The Lambda series is corrected for blue to far red range 435-850nm while the VC (violet corrected) series corrects from UV to red 405-656nm.

Hi all,
Would someone please explain the primary differences between Nikon's Lambda series and VC series of Plan Apochromat objectives?

From their website, I understand that the Lambda series objectives have better transmission towards the red end of the spectrum than the VC series objectives. Are there any relative advantages of the VC series?

Thanks!
Kyle
