It seemed to be fron focusing and so, of course, I alarmed many here in the forum. So, in round two, I used both the 1dN and my 20D, results here: https://photography-on-the.net …hp?p=1257921&postcount=21

And here's one from yesterday when I thought there might be an issue:

Mar 06, 2006 18:04 | #3 Ok...even though there's been no feedback, I will update on further testing. Every test I have done...straight on, angled, flash, 24-70, 70-200, 85, 50 mm lenses...it has a definite front focus issue. I am bummed...

That tricycle is not a proper test unless the seat was white. Remember AF is NOT perfect. Test MF too. defordphoto | Celebrating the art of photography®

Test MF too. I hear you...I've done over 100 shots today in all manner of light with all manner of targets...consistently resulting in front oriented focus while in AF. MF results seem fine...thanks for reminding me.

Maybe I am just old-fashioned in my almost 43 years of age, but geez, anymore you pay top dollar for something and get stuff that needs to go right back to the factory. It's like you pay 100% for something but only get 90% or less of what you paid for. I know I am not the only one who ever got bad stuff, but it really frustrates me to no end.

Ok, this venting was brought to you by Canon! If I could wave my magic focus wand to fix it I would. Sorry. The photos you show here in your tests are not under proper light IMO and the subjects are too similar. Only Canon can fix this. defordphoto | Celebrating the art of photography®

No kidding as I have to agree with paying top $$$ for a product you'd think the QC would be a little better expected but we all know stuff happens in any aspect of human or even technological intervention.

Also, for $4K, the darn thing ought to be giving me a kiss while I am shooting...at least for the first week!
