Yes, that is interesting for sure. They aren't fullsize, but hey, it's also 4 stops... Looks very okay to me!

I've noticed something strange

in the canonrumors front page, on the right, there's a panel where you'll find the forum threads with the latest forum messages
http://www.canonrumors.com/

except the negative threads don't appear
for example this one: http://www.canonrumors.com/forum/index.php?topic=5828.0

I'm pretty sure there's a perfectly sensible explanation for this... I'd love to hear it...

Click to expand...

That section of the CR homepage is populated by threads with recent activity. But...it's delayed by an hour or so from the actual activity on the forum. That snarky negative post you just read (or posted, as the case may be) on the forum will make it to the front page, eventually. You can see this easily in that those home page links point to posts that are several posts (or pages) back from the most recent post in very active threads.

As I've stated before, another conspiracy theory dashed on the cold, hard rocks of reality.

As for threads being deleted, mods do that sometimes, but much more often I've noticed that similar threads are just merged together, so one or more seem to disappear but they really haven't.

very reasonable explanation, thanks

Dont fiddle with the options until you know what they do - take the settings out of the bos, except to change to RAW.

The only other function to change will be the AF - I suggest turning on the expanion point (all points round) as this will help the AF on moving objects.

Here is a link to the beta version for CS5 from Adobe.

http://labs.adobe.com/downloads/cameraraw6-7.html

I just installed it.

Apr 24, 2012

Right, difficult to tell now that link is closed, but it was described as a version II model, and I'm guessing that the 52+ bids nearing the close are an indication that such was in fact the case.

If you've already spent all that on the Mk3... why go for 4th best? The 2.8IS II is by far the better choice over that soft marshmallow of the Siggy...

Canon has listed this as one of the fixes in the new firmware version, glad to hear it works right now!

with that in mind, my question is: Has anyone thought of making an adapter for canon lenses so we can use it on nikon bodies?

Click to expand...

This is exactly why there are currently a lot of dual brand shooters. The Nikon D800 has tempted a lot of us.

absolutely! taking to account the 14MP difference, a lot of people predicted it will not be capable to handle high ISO and noise but to my point of view 5d3s' edge is not as big as a lot expected. From what I saw the only big difference is on the video capabilities(high ISO) which for most of us didicated to STILLs is neglegible.
At this point I'm looking at all sides wether to get the 5d3 or d800. Swicthing? NO! i'll keep my 50d and my glasses if ever I decide to get nikon as I don't want to loose a couple hundred bucks on selling my stuff.

Pieces Of E · Apr 24, 2012

I thought the whole idea of buying expensive electronic items like 5D III's would be to get it brand new with the USA warranty card, etc....but I guess if you have the cash to expend,,then buy off craigslist or beach camera or man in the street.
Oh, and mister student, maybe you should buy an old manual film slr and LEARN the craft you are portaying as here before buying a 5D III(then you'll still have plenty of beer money left over to enjoy after classes)

Anybody has tried the new Tokina for FF model AT-X 107 AF DX NH Fisheye on the 5D MIII ??

Here it is: http://www.thkphoto.com/tokina/products/atx/atx107afdxnhfisheye/

I find no pictures in Pixel Peeper..

http://www.pixel-peeper.com/adv/?lens=1089&camera=1113&perpage=12&focal_min=none&focal_max=none&aperture_min=none&aperture_max=none&iso_min=none&iso_max=none&exp_min=none&exp_max=none&res=3

Maybe you have some photos to show of this new product? I think it may be a serious contender to the Canon EF 8-18 f/4L.

Renato · Apr 24, 2012

Thanks, keep us posted of your findings.

or they will just post a link to the techradar test with a big question mark ?

and ask how two DxO test can have different results.

http://www.canonrumors.com/forum/index.php?topic=5868.0

Click to expand...

none of the techradar results make much sense at all

Click to expand...

Why don't TechRadar's results make sense?

The one thing I walk away from those graphs with is the fact that Canon is obviously doing something pretty nasty during the in-body JPG conversion to have that large a discrepancy in the results.

Maybe it's because I want to believe those results, but they just feel more feasible. Especially with the D4 having higher scores then the 800.

because the DR improvements go flat on the low end to a degree that nobody else has found to be true and the relative differences between cameras don't remotely match what others have found

and, if you take shots, and play around with them, the relative performance between cameras still doesn't match what they got

kbmelb · Apr 24, 2012

My mkII and mkIII histograms for identical shots are almost identical. I have also noticed with this test mkIII's AWB is also more accurate. But I guess that is to be expected.

In post with all things were equal the MkII looked a little brighter in center and the histogram of the mkII was slightly more spread to the right, but spiked similarly, which I'm likening to dynamic range since the mkII filled in blacks and pushed whites more (see below). Both files were raw imported to Aperture so no lens corrections were on in either.

While I was there I pushed the shadow levels and brightness to the limits and noticed the 5DIII has substantially more DR and much better noise control. Both these are ISO 400 and pushed equally. I'm impressed. the mkIII may not be the 800 in DR but I'm happy.

Disregard the fact the files say they are both from mkIII, that is the way I cropped them in the same PS file together.

Can't seem to update my 5D Mark iii with the Firmware Version 1.1.2. Wondering if anyone else is having this problem? I only tried by using connecting camera to computer by usb cable then going into the EOS Utility. Fimware is suppose to fix these issues below (which by the way I never had, so I'm thinking I may not need it) ..... what do you guys think??
1. Supports a new accessory, GPS receiver GP-E2.
2. Fixes a phenomenon where a pink cast may develop over the image when the shutter is completely pressed with the camera’s power turned off (by the auto power off setting).
3. Fixes a phenomenon where the camera operation stops after one shot when shooting in High Dynamic Range (HDR) mode.
4. Fixes a phenomenon where the Shooting Date/Time in the EXIF data of the image shows a later time than the actual shooting time.
5. Fixes the time zone for the Samoa Islands.
6. Corrects errors in the Finnish menu screen.

CANON ALL THE WAY. . .

http://fstoppers.com/video-canon-5dm3-5dm2-and-nikon-d800-low-light-video-test

BEST ALL ROUND camera this side of the universe. . . heck I can't see ANY 95 in the Nikon example . . . . only in the Canon.

Click to expand...

That test demonstrates that a certain N camera got Destroyed 800 times over and over!
but yeah some would argue it's *just* the low light video part..

Click to expand...

Really?
How about trying what I tried, since it's obvious the light levels are very different in the 3 videos stacked on top of each other.

Run the video twice side by side, stop one video at ISO 800 and look at the D800. Let the other video run until the 5D3 comes up to the same level of light as the D800 has in the paused video.
What do you see? You need at least a full ISO stop to get the same amount of light.
Which means the D800 is being disadvantaged in this 'test' by a whole stop at least when you get to higher ISO levels, and of course you'll have more noise etc. Makes the 'test' rather pointless.
Or it means the 5D cameras is running way lower ISOs than they claim to be running.

Also, it appears that Canon has NR on and Nikjon has NR off. So the comparison is even more pointless.
Pity they couldn't do it properly when they did it at all. As the guy says who did it, "only had the cameras for a short time". Maybe he just doesn't know how to set them up exactly the same. Menu systems can be such a drag....

Click to expand...

Yes something is going on. Either canon overstates the ISO true value or Nikon understates it. Thus although the canon has some advantage, at equivalent exposure the Nikon is at 1 to two stops brighter. Which means the canon needs to boost 2 stops to match it. So ISO 800 on Nikon is about 3200 on the 5d3 to get the same image. The real advantage of the mk3 is hard to measure then.

However the Mk 3 detail is so mushy, it does get killed for daytime shooting :|
nikon 422 hdmi out just blows it out of the water.

For what it's worth, according to the almighty DxO ISO sensitivity, for Nikon D800 and Canon 5d3, the 5d3 is closer to the norm than the D800 is...

http://www.dxomark.com/index.php/Cameras/Compare-Camera-Sensors/Compare-cameras-side-by-side/%28appareil1%29/795|0/%28brand%29/Canon/%28appareil2%29/792|0/%28brand2%29/Nikon

Cant quite figure out why it's so bright unless something wasn't quite equal.

Click to expand...

DXO mark measures still images NOT video. It is clear that setting both cameras at ISO X, the nikon is brighter meaning one of the cameras is NOT reporting the ISO sensitivity correctly. As to which one it is, one would have to take a control camera, like a 5DmkII or D3s and repeat the test. I suspect nikon goofed off and what they report as ISO800 is really much higher...which is silly of them because this makes them look worse than they actually are on these candlelight tests. It can also seriously screw with your exposure if you use an external meter.

The 5d2 was used in that test and looks similar to the 5d3 in terms of brightness but noisier... Of course if the 5d2 didn't report the ISO the same either, as you suggest may be happening in part by one, both, or all cameras, then we may never know unless we base them off of a still sample which should be pretty darn close within 1/3 of a stop. I dont know why they wouldn't use the still's ISO sensitivity levels, but i'm not an engineer or video guy so doesn't bug me either way.

The Zeiss 21mm is still f/2.8... I would like something f/2 and below if I am going with a prime (besides the 17mm TS-E).

21mm is a good focal length, but there are some places where even 16mm isn't wide enough.

Having a lab available to you to use yourself is invaluable. Community College, best value hands down.

Apr 24, 2012

I need to tap into the wealth of knowledge from the canonrumors gang.

I will be doing lots of shooting later this summer with the new 1Dx and 5D3 (hopefully) with the 400mm f/2.8 MK I lens. I expect that these cameras will easily be able to drive the autofocus on this lens.

My question is with teleconverters. I have the 1.4x II and figure that will provide excellent results. Is there any reason to think that the 1.4x III will perform noticably better than the 1.4x II with the older lens? I could see having the 1.4x II between the newest lenses and bodies not being preferable.

Thanks for any help.

hhelmbold · Apr 24, 2012

Great to hear and I figured it must have been just a typo

bp · Apr 24, 2012

I never use the camera's meter for night shoots anyway - usually just trial and error a few because the camera usually wants to bring levels up to daylight. so... no

I'm not sure if I'd want to switch to Av or Tv mode or not. Problem being is that the shutter speeds will suddenly start to drag below 1/50 or 1/60 which is pretty slow for a show to begin with.

Click to expand...

How does that work in Tv mode?

Just put it in Manual mode at, say, 1/60/f4.0 and auto iso and then there will no more adjustments needed

Well, true, just with Auto-ISO it'll quickly max out at the top of the ISO as much of the frame is dark, while the main subject(s) will still have decent lighting because of the placement of the lights, and will probably end up getting over exposed.
