The Canon EF 70-200mm f/4L IS II USM Lens has been announced. I anxiously await this lens in my hands and completion of this review will be a high priority at that time. In the meantime, I'll share my expectations for this lens below.
The Canon EF 70-200mm f/4L IS II USM Lens was announced at the same time as the Canon EF 70-200mm f/2.8L IS III USM Lens, but unlike the f/2.8L III, deemed a "refresh", the f/4L IS II is a very significantly upgraded lens. I have owned and loved the original version of this lens since it was first released and knowing that it has been significantly upgraded is of course exciting.
Why is this lens so special? First, the 70-200mm focal length range is tremendously useful. The great build quality, AF performance, 5-stop image stabilization and impressive image quality are at least as compelling. That all of these features come in a small, lightweight package makes the lens very comfortable to use. That a lens with all of these features has a reasonable price wraps up the deal.
What are the Differences Between the Canon 70-200mm f/4L IS II Lens and the Canon 70-200mm f/4L IS Lens?

  • The II has an improved 5-stop image stabilization system that is very quiet and includes mode III
  • The II has optimized Super Spectra Coating for reduced ghosting and flare and improved contrast
  • The II has a reduced minimum focus distance (3.3' vs 3.9' / 1m vs. 1.2m) and an improved maximum magnification (0.27x vs. 0.21x)
  • The II has improved image quality and an improved optical design while retaining the same 20/15 element/group counts and same fluorite and dual UD lens count
  • The II has a 9-blade rounded aperture (vs. 8)
  • The II has improved weather sealing, matching the other recently introduced L-series lenses
  • The II has fluorine coating on the front and rear lens elements, keeping them cleaner and making them much easier to clean.
  • The II has Canon's newer, whiter paint color, matching the other recently-introduced lenses.
  • The II is very slightly larger and heavier and has a slightly larger 72mm filer size (vs. 67mm)
  • The II has minor typographical changes including the words "Image Stabilizer" and "Ultrasonic" printed below the focal length range and next to the focus distance window. The gold "Image Stabilizer" has been removed from the mount area.
