Canon Announcement Delays Possible, Including The Canon EOS R6 Mark III

[Michael Clark]

So sad, so sad...
I was a few minutes late. When I happily pressed "enter", the message said "all sold".

Dang it! You missed that whole 0.8889% discount!

PS: I'm a liar.

It that a lie? But if you're lying then you're saying you're not a liar, but if...

The most annoying thing about Canon mirrorless cameras is the focus point. With DSLRs, it was exactly one point. Now, even when selecting just one point, it's actually an area, which means it often doesn't focus where it should. It's much more imprecise than before, and this isn't an opinion, it's a fact.

From Andre's blog way back in 2010...
"Eventually, I decided to map out crosses inside each AF point, so I can focus on the subject more accurately. I placed a white sheet of paper with a small black square on the wall and moved each AF point perpendicularly to each edge of the black square until the focus light in the viewfinder started to blink, which indicated that I reached the end on the AF cross in the given direction."

"Repeating this exercise once for each of the edges gave me four shots where the inner edge of the black square indicated the end of the AF cross in each direction. I superimposed all four shots onto each other and ended up with this picture for the center AF point."


"So far so good - the cross inside the center AF point was pretty much what I expected. Note that the cross extends well beyond the red square marker in the viewfinder, which means that if there is more detail outside of the AF point marker, the camera will focus on that detail."

"After taking 72 shots and merging each four, I had the complete map of all AF points for my 7D. Let's take a look at the second one from the top in the center column, which is the one used in the sample shot above."

"Now it all makes sense - the cross inside this AF point extends well into the top AF point and the camera focused on the detail in the background rather than on the fuzzy police bear."

And:

From Canon technical advisor Chuck Westfall back in 2008 when the 5D Mark II was introduced:

"This graphic shows the relative sizes and positions of the EOS 5D Mark II's focusing points."



And from Canon upon release of the EOS 7D:



The top map is what one sees in the VF (less the numbers labeling each AF "point")

The middle is a map of the PDAF sensor array. Keep in mind that microlenses aim the light coming into the array before it falls on the sensor array.

The bottom is a map of the areas of sensitivity for all of the focus "points" superimposed on what one sees in the VF.

To the left is a guide that indicates which pairs of lines are active for which "points" as numbered in the top map. The center cross-type AF "point" is indicated by the red shading.
