Canon EOS-1D X Technical Report

[Loswr]

I'm surprised that the X-sync speed has dropped to 1/250 sec, when the 1Ds Mark III and 1D Mark IV sync speed is 1/300. For a machine that can do 12fps I'd have thought it would be 1/300 or even higher. That extra speed can be handy before having to switch to HSS.

1DsIII is 1/250 s. The 1DIV is 1/300 s - the small sensor means a shorter distance for the curtains to traverse, so they can cross faster, allowing a higher sync speed for APS-H.

I thought there were mutliple blades for this - vertical blinds open-shut wheather full frame / APS-H. Maybe they just use electronic shutter these days (depends on video shutter speed capabilty)

No, there are still a pair of curtains (titanium, I think). The point is that with APS-H the curtains don't have to move as far to cross the sensor, compared to FF. So, assuming Canon drives the 1-series (1D and 1Ds versions) curtains with their best motor, and the curtains move at the same speed, the shorter distance with APS-H means a faster sync speed can be achieved.

You know when this thing comes out you won't be able to get on anywhere. I placed an order for two and had to notify my Canon Pro rep to ensure I get them on release.

It's doubtful we'll see anything Raw or otherwise until a couple of weeks before release. The thing is way off ready imo.

I have never seen an anouncement of this sort so far ahead in advance. They might just have their %^&t together. Esp for the olypmics coming up. If anything I think it would be the D4 users that should be most concerned. Canon seams pretty penis sure of their product and themselves atm. Never seen that before.

@ neuroanatomist - About the shutter mechanism, I think you probably know more than me. Do they use the classic shutter with live view? I remember my old olypmus C8080WZ used to do 1/1000s with a decent flash (but low) output. Loved my 350D when I first got it. Got heaps of great shots with that. I screwed up the IR coversion of that when a few screws rusted after all the slat water splashes it copped.

Live View uses an electronic first curtain. In fact, Live View and silent shooting mode (if available, actually it's the default on xxxD bodies in Live View) gives better vibration reduction than mirror lockup alone.

CCD sensors can be flushed much faster than CMOS, and thus can have both 'curtains' as electronic.

Dude, glad you know more than me! I was wondering about the electon flush between exposures. I have avoided live view landscape shooting for this. So, electrons are flushed before exposure for live view stuff too. Good news to me! Thanks mate

 

[5D Freak]

I guess there still is a disadvanage of sensor heat with live view. Still try and avoid it I guess. Live view focusing for astro only on first exposure. I generally through away that one anyway.

 

[distant.star]

The cymbal isn't real either!!

Gee, this drum roll has been going on for some time now. When does the cymbal crash?

 

[5D Freak]

it still sucks, then D4.

Boo hoo to you. You can have the D4. Bit of double kick bass drums........Hope you have the lenses to suit. My old man is a Nikon man. Wish he had a Nikkor 14-24 that I can use on my 5DII for astro. Cymbals please.... Might have to buy that for him for doing my tiling at my home. 300 buckarooni adaptor.....Boom (Outro bass kick). Sweeeeet

I import products by sea frequently and it takes 5 days to get here. [snip] [shipping the 1Dx] would take under two weeks.

From where do you regularly import products by sea? Unless you have a private fleet of bluewater hydrofoils, five days is wildly unrealistic for bringing containers to the US from Asia.

The great circle distance from Tokyo to San Francisco is ~5500 miles. To make that trip in five days, you'd need to average about 46 MPH. Container ships typically cruise at 25 knots, which is a little less than 29 mph. I'd be fascinated if you can show me a container ship that can make anywhere near 46 mph.

It takes about eight days to go from Tokyo to San Francisco at 25 knots, so your other estimate--two weeks door to door--seems much more reasonable. However, many container ships have begun to cut speeds to 12 knots for the fuel savings:

Maybe I misunderstood your initial post, but the idea that 1DXes will cross the Pacific in five days is silly. It's just as silly, in fact, as another poster's speculation that those cameras have already begun a three-month crossing.

Banque Populaire - a 130ft sailing trimeran just completed the around the world 'Jules Verne' record in 45 days which has lifting foils akin to hydrofoils. Fastest long distance ocean going vessel - faster than any military vessel (even though they're powered by nukes) given the same conditions. Average speed for the journey was close the 30knots. The biggest threat on the ocean for these craft are UFO's - unidentified floating objects. Floating containers that fall overboard - happens all to often. Lucky it did strike one loaded with 1DXes or even 5DII's (I'd cry to see that!)

 

[5D Freak]

Wow- just read that this boat also holds the 24hr record - 907 miles (not kms) averaging 37.79knots!

Jason, welcome to the forum, nice first post. :

Depends what it is you're importing. If it's something like laptops, they're already well on their way before the orders get placed. Hence the five days delivery can be feasible. Sony knows they'll sell 1000 Vaios next week from a single shipment to San Francisco, they just don't know exactly who is the end-buyer this time - so they send them before they go obsolete!

Anyway, given the noise and fuss about the new pro Canons I'd guess they'd be worth sending by air freight.

>> Canon has posted a technical report about the Canon EOS-1D X at their Canon Museum. It’s a good quick reference for the camera.

So how long does it take to ship to the UK then.... cos that's where all the 1Dxfiles are headed ;D ;D ;D

A list of accepted focussing screens is given, but the Ec-S high-precision one is not among them.

If it has been desupported, that would be a real step backwards. Users of fast manual-focus lenses in particular would have a problem; with back-button autofocus set, you'd need to hold the AF button down to get focus confirmation. Users of lenses via unchipped adaptors would be in real trouble.

Hmmm... "The EOS-1D X supports the Ec-A, B, D, H, I, and L focusing screens."

Still, I wouldn't panic quite yet - the technical report lists only 6 screens, but the Canon CPN spec page states, Focusing Screen: Interchangeable (12 types, optional). Standard Focusing Screen Ec-CV. So, I suspect the 1D X will take the Ec-S, or Canon will come out with a 1D X-compatible equivalent.

Any update on this subject?
