I just tested using Chrome and got 5D Mark IV
body only for $4543.64.
And using old Internet Explorer, I get the same. (I don't have Edge installed yet, so can't test it.)
But in Firefox I can only see 5D Mark IV with C Log for the higher price of "$4729.45". For some reason Firefox won't show me a "body only" version of the camera at the Blitz website.
I did not notice "USS" there before. The reason I didn't see it was because I didn't click through to the full listings, as shown above. But since those are actually US $, that's even worse than I thought!
I have no idea why you are seeing the so much cheaper price of $1429.45. That's even the version of the camera with Canon Log and some other accessories, which usually sells at a premium compared to the body only.
I seriously doubt they would send you that camera at that price!
Yes, I quoted B&H Photo prices for 5DIV body only earlier: $2,699. The price for the camera at Adorama and Amazon (direct) is exactly the same. Those three are almost certainly the largest authorized Canon dealers in the US. I would be highly suspicious of any 5DIV priced lower. It would likely be gray market (effectively no warranty). Or it might be "seller refurbished" (a nice way of saying "used"... it can't be "factory refurbished" because Canon only sells those directly from their website now).
$2699 is also the list price of the 5DIV body only at the Canon USA website. The version with C-log is $2799 there.
About the best deal in the US on a 5DIV is $2429 for refurbished (same warranty as new, also come with same things as new and usually look new, but come in a plain brown box):
https://shop.usa.canon.com/shop/en/catalog/eos-5d-mark-iv-body-refurbishedThe Blitz Camera prices just seem to be very high... when viewed in most browsers. Ridiculously low in others! You might try refreshing your browser. Maybe you are looking at some old sale price.
EDIT: Incidentally... when I view the Blitz web page in Firefox, I see the following:
This Canon EOS 5D Mark IV DSLR Camera with Canon Log and Accessory Kit from B&H includes a full-frame DSLR with a gamma setting that helps filmmakers record with an expanded dynamic range. It is bundled with a spare battery, a memory card, and a protective camera bag. Blitz website referring to B&H? Weird!
I don't see that text at all when viewing the page with Chrome or IE.
But in all three browsers it appears much or all the rest of the page design was copied directly from B&H.
Also I notice there are absolutely no buyer reviews for any of the 5DIV listings at the Blitz website. For comparison, at the B&H Photo website the 5DIV (body only) has 1244 buyer reviews, while the version with C Log has 196 reviews. At Amazon Direct there are 833 and at Adorama there are 771 buyer reviews (for 5DIV body only in both cases... I just didn't check the version with C-log at those sites).
