Thank you for your thoughtful post, and no disrespect was taken at all. I appreciate you taking the time to read my, admittedly, very long post and responding.
That is interesting information about your 24-70 II and FoCal giving you a crazy curve. I did notice some autofocus lag on my original copy on one side (the left) of the frame. However, the photos still looked good. Maybe you’re right and it was just a glitch in the software? FoCal isn’t always as reliable as it should be… On my current lens copy, however, I have a very linear curve, and at the time I did test it with the same software version of FoCal I used previously. At this point, I guess I will never know for sure; I was worried enough by the bad curve and slower AF that, to me, it warranted sending it in…which is where my troubles with Canon Canada started. I do remember being a bit surprised at the difference in AF speed lock ons with the new copy, though. I suspect that with your copy it’s indeed FoCal glitching out if you’ve not noticed any photo quality loss or AF performance impact.
If you’re running more tests on your lens I am happy to send you copies of my charts for comparison, if you’re interested?
From my online reading and research it seems that specks appearing in the viewfinder is normal for the 1D X — maybe it has something to do with the interchangeable focusing screens? I still maintain that the amount that was in my original pentaprism was far beyond normal and was some sort of defect, especially since the camera was so new. Before I first sent the 1D X in I sat and was actually able to count upwards of 60 different particles after a day’s shooting, and it was just getting worse and worse with every shutter actuation.
Reading others’ posts on various forums, debris that can’t be blown out is in either two places: between the super-imposed plate and the bottom of the prism, or inside the prism itself. Dust in the former area is by far the most common and can be cleaned with disassembly of the camera. Debris in the pentaprism calls for a replacement, which runs at $800 (not including CPS Gold or Platinum membership discounts).
If and when you eventually send your camera in for a cleaning, if you wouldn’t mind, please let me know what they tell you or do?
Anyways, your approach I think is the right one: I shouldn’t let it cause me grief at this point. Everything is certainly better than it initially was. I still want to, and probably will, write a letter to Canon, though. In my opinion it’s still important to give feedback. I’ll give CR Guy a holler to see if he has any suggestions as well. But the main thing is to just enjoy this camera now.
I also just want to say that most of my Canon products are bullet proof. My 70-200 II, my most used lens, is a bloody tank. Same goes for my other cameras and L glass too. With the 1D X and 24-70 it’s just a shame because of the added expense of those products; they are top-tier and their price reflect that, so it stings a bit more when there are problems.
I'm sorry to hear about your experiences and have actually had both happen to me. I don't mean any disrespect, when I say this, but neither issue has caused me enough grief to do anything about them. I'm not trying to belittle your issues as I'm sure your problems are more severe, or you wouldn't have sent them in for service. Those turnaround times are terrible and I would be beyond frustrated if I were you.
FoCal shows a crazy curve with my 24-70 II, but I have never seen any issues in actual photos, so I think it's either a glitch with the software or my testing or both. Or maybe FoCal is right, but again, the photos from the lens are razor sharp so I'm not too worried about it. What were you seeing in your photos? I'll take a closer look at my lens now that you've mentioned this issue.
With my 1D X, I have noticed small black specks in my VF, and I tried to blow them out with no luck. They aren't really bothering me enough to do anything about them. I was planning to have CPS give it a once over during a Clean & Check, but haven't sent it in for that, yet. Your information is interesting, however, and I'll be curious to see how they handle it. They totally botched a 5DII VF cleaning a few years back and I had to send it back, so hopefully I'll have better luck this time.
Again, I'm very sorry to hear about your issues and wish you better luck in the future.
