Quote: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.
Ah, here you go. So between your Canon bodies and various lenses, you pretty much had random luck in terms of accuracy.
This is exactly what I'm talking about.
I tested about 8 MFT lenses on more than 4 bodies. All lenses with every single body focused pretty much perfectly. There is simply no AF accuracy discrepancy.
Now I shoot Fuji. I have 5 lenses. All 5 lenses focus spot on. Again, no AF accuracy discrepancy.
With a DSLR it's just a nightmare to not know how well or bad a lens will focus before buying it. Fiddling with micro-adjustments, testing procedures, etc. With mirrorless the issue is simply non-existent.
This is what I mean by reliability. The same simply doesn't hold true with a DSLR, as you stated yourself.
Anyone who is objective and reasonable would come to the same conclusion.
Why is it so difficult for you to admit that AF on a mirrorless camera is more reliable than AF on a DSLR?
On a final note, 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?
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.
