You are funny. The 350D was a DSLR from 2005, and it was famous for its temperamental AF (could have been a Pentax ). The lens was a Sigma with a simple DC motor, which gave terrible results with live view on the 450D.

The Tokina, what can I say. It was a Tokina. More crude AF motor action can't be found.

 

Yes, my 28-135mm Canon lens is defective. Is that defective old zoom a good example of how big aperture lenses on modern Canon DSLRs perform? No, of course not. 

 

Of course.

 

Where were we? Can you please answer these questions in all honesty:

• On a DSLR, which is more accurate (when shooting a still subject): PDAF or CDAF?
  
• Isn't it true to say that Canon and Nikon DSLRs provide AF micro-adjustments as an attempt to correct AF accuracy issues?
