He set out to try and prove whether doing just one AF press or Multiples for fine tuning made a difference. What he seems to have proved instead was that new bodies need new lenses for improved accuracy.

Hmmmm.. Very interesting. I guess I can stop double tapping now. Also, I have ben using LV focus whenever possible thinking the results are better and the data seems to prove it out.


Not sure why, but call me JJ.
I used to hate math but then I realised decimals have a point.

So...what your saying is that I need new equipment to get the best possible outcome, for all components as they get upgraded. New body, and news lenses as each model is upgraded.

I'm not sure whether to celebrate (yay, new toys!) or cry (boo, costs money).

Yeah, I know. ;)

Imagine 10 or 15 years ago, when the film and then digital EOS system and EF lenses were in their early years - the stuff that is "old tech" today must have seemed like a dream: 70-200 2.8 IS mk I, the 5D II, etc. So I'm actually looking forward to this next evolution in AF accuracy.

I'm just trying to figure out how to pay for it.

Also, when many 90s lenses were designed, the standard for in focus was 8x10 prints. How would you even pixel peep those? :) You could probably be off by 5-10% and it would still look in focus most the time.

^^^ Come on- sounds like the original use for a loupe ??? Something tells me you've been around a while... Didn't pixel peeping come into fashion with the age of digital ?

Nah, I'm not that old, just a classic know-it-all smartass with too much time to waste on forums. Only just turned 33.  :p
