| p.5 #20 · Firmware upgrade for 300mm, 400mm, 500mm and 600mm L IS II |
The only one I know of who had some difficulty with the subject of MkII AF response was B.Carnathan of TDP. He apparently contacted Canon as well on it.
The rest of early MkII owners were singing praises to their lens AF response.
Be that as it may, before I have my MkII lenses updated to the new firmware, I will not know if the new firmware addresses my concerns or not.
It is also possible that Canon is now fixing something totally unrelated.
The first motorsportsshoot a few weeks ago with the new X and my 400MKII, was very disappointed.
after the first run, I started sweating and said to myself: oh no!
after analysing the 700 raw images the next day, having contact with cps, I went to them.
CPS tested about half a day, a special technic man came especially over [ about 30 min driving] and the conclusion was after lots of coffee: nothing wrong, but try other cases with several different presets.
so back home the testing began again, till the news of the new firmware came out.
next week I will drive again to cps.
my thoughts are with all the Canon ambassadors and testers who worked with this combo, before the lower-class people have to try: didn't you noticed this? Where are the experts?
after half a day, my experience said, something is not so how it should be.
don't understand that.
