p.1 #1 · Anyone use a 5DM3 with at TC to AF at F8?
If you followed those acronyms you understand the scenario.
I presently have 5DMkII & 1DsMkII.
I have been hanging on the 1D series because I can use my 400/5/6 with a TC and get good AF, sharp images.
But the temptation to consolidate things has me looking at a 5DMk3 to replace both functionally.
I don't really need to bodies & don't do sports.
I occasionally do wildlife & some events.
I have heard folks talk about taping pins in the past
But I want a current experience with a 5DMk3, with a TC and the AF performance at f8
Too bad Magic Lantern hasn't offered a firmware package to make this a menu selection.
Why Canon limits this even now on the 1DX without at least the option is mystifying.....

[There are some 1.4x's that don't require taping. The downside is that they don't report the correct fstop in the exif.]
But in any event, I have used tamron 1.4x on 100-400L with 5diii (starts at f8 with 1.4x) and it works well. Better than the 7d in similar circumstances which also focuses with the same 1.4x on it.

Scott,
Thanks for the info. I have Kenko ProTCs that I have been very satisfied with results.
Hoping to try them on a friends 5DMkIII soon.
So guess my next question for folks might be if the Kenko needs pins taped....
Ian,
I tried some searches, but the acroym was successful
Thanks

I taped my Canon 1.4III, attached to 100-400L and it does AF on 5d3. Performance is crappy, you need to press focus button couple of times until it will finally focus. I will probably crop my shots with better results.

I tried taping the pins on mine, and it was hit and miss, mostly miss. It was a waste of time. Iy might AF fine on some lenses in very good light, but at best it will be slow, and will likely hunt a lot. I also found that it did not focus accurately with some lenses.

Is this your own experience on a 5D Mark III? Or on a different camera, like the 5D Mark II?

No mystery at all; a Canon decision to widen the spacing of the AF sensors in the viewfinder, which helps a large number of users, while hurting a specialized few:
"The 61-point AF system not only has 16 more AF points than any of the 45-point systems, it is also 20% wider in coverage (19mm vs. 15mm), making it easier for photographers to keep their subjects within the active AF area.
AH: We understand due to the large number of cross-type and double-precision cross-type sensors there was not enough room to fit the f/8 line sensor in the new AF sensor. However for wildlife applications the 2X Tele-extender in combination with f/4 super-telephoto lenses offers great flexibility. Is it possible for Canon to address this issue?
CW: This request has been conveyed for consideration."
