How To Do Autofocus Microadjustment On Your Lens (tutorial)

Autofocus Microadjustment

Here is something useful. A video about hot to do autofocus microadjustment.

The 14 minutes video below by Michael The Maven shows how to microadjust autofocus on your lens using a cereal box and a ruler. He uses a Canon EOS 90D to show it.

The cereal box and ruler method allows photographers to quickly visualize where their lenses are focusing and to verify if they are out of alignment. This video demonstrates the philosophies of MFA (micro focus adjustment) and some of the principles to become familiar with if you decide to try this on your own.

If you prefer there is a neat written tutorial about how to do autofocus microadjustment by Canon itself and you can download it here.

This May Be The Pricing Of The Upcoming New Canon RF Lenses

RF 24-70mm

We expect Canon to announce three new Canon RF lenses for the Canon EOS R system, RF 15-35mm f/2.8L IS, RF 24-70mm f/2.8L IS, and RF 70-200mm f/2.8L IS.

These lenses will most likely be announced along with the Canon EOS 90D and the EOS M6 Mark II. All are expected to be announced on August 28th, 2019. Specifications (90d | M6 Mark II) and promotional videos (90D | M6 Mark II) for both cameras have already leaked.

The suggested prices for the three new RF lenses appear to have leaked in Thailand, and so starting from the price in Thai Baht we can get an idea about where the US$ prices will be.

  • RF 15-35mm f/2.8L IS 82,600 THB – $2,499
  • RF 24-70mm f/2.8L IS 82,600 THB – $2,499
  • RF 70-200mm f/2.8L IS 93,500 THB – $2,799

These lenses have already been announced by Canon, and prototypes have been showcased around the world. For sure these will not be inexpensive lenses.

The same source suggests the RF 15-35mm f/2.8L IS and RF 24-70mm f/2.8L IS lenses will start shipping in October 2019, the RF 70-200mm f/2.8L IS lens will be available in December 2019.

Stay tuned for more to come….
