EOS Bodies / Re: EOS 7D Mark II Test Camera [CR1]

I wouldnt be surprised to see it priced over the 5diii.  Canon has never let us down by pricing stuff at 2 year ago pricing.  Expect them to drain your wallet as much as they can before bringing the price down.

Interresting, in Japenese forums he specs are handeld a little bit better. Price over the 5D3

In fact I wouldnt read much into it at all.  There are likely several different configurations running around.

If DR improvement is not mentioned it won't happen

This is just a quick CR1, probably leaked from a beta tester, doesn't mean much either way concerning dr/noise or af performance...

Video ‘stills burst’ mode 30/60 fps
I'm not sure what this means...are they suggesting that it will capture 30 fps in the full 21 MP RAW mode?

It means that the lv buffer is written as a hq-jpeg file as fast as possible (better quality than grabbing frames off a video). What resolution the file has depends on Canon's live view implementation, for example on the 6d it's 1816x1210 ... Magic Lantern can already save this, though only as one shot.

Many sites are now stripping the EXIF information from the images when they are uploaded to conserve space.  Considering the numbers of images posted to these sites, that small amount adds up over time.

I paid for it, but have heard nothing from them. I doubt very much that the person who stole my gear has not uploaded any photos to popular sharing sites.  Con job I think.

MKII lenses while quite good are not perfect and is what we see in the real world.  The sensor can only reveal what the lens can resolve.

Once you reach the resolution limit of the lens, the sensor will represent the image the best it can.  If the data is not there it will be soft. 

Thats not how lens resolution works - instead higher frequency detail gets dampened, like in a low pass filter. More resolution just means slightly lower contrast for microdetail. Thats unless lens aberrations convolute detail in a nonrecoverable way, but the new canon lenses show little tendency to do so.
(But even with perfect lenses we're sooner or later have to choose between lack of DOF and diffraction...)

The higher pixel density is what will out resolve the glass, even MK II glass.  Once you reach the resolution limit of the lens, the sensor will represent the image the best it can.  If the data is not there it will be soft.  22MP and MKII glass is a great match.  Pushing the pixel density higher wont improve the image.  You will likely need to add sharpening to your photos to get the same kinds of edges you would get with the 5D3 or even the 7D.

It's all theoretical until we actually see what the new sensor is!  ;)

It will only produce better IQ if the lenses improve.  Once it does arrive you will hear on these forums about how soft it is.  This will be due to lenses and not the camera.  Even with the MK II lenses, the images will be softer and the complaints will start.

I think instead of focusing on 135, they should expand into larger formats where the extra MP will be of more use.  Makes no sense for the sensors to out resolve any of the lenses currently in production.


I'm not so sure about that. Are people with an 18 MP 7D complaining about the softness of the MK II lenses? If you made a full frame sensor with the same pixel density of the 7D, you'd be around 47 MP (unless my source on that is off).

A crop from the center of a big MP sensor would look much like what 7D shooters ( and I suppose anyone with a decent 18 MP APS-C body) are shooting right now. I know there are a lot of complaints about that sensor, but none that I have heard have to do with it making high end glass look soft.

Maybe my logic is off there, but I don't think you'd be pushing it with the newer lenses.

It's been shown also that MK II lenses AF better with new bodies such as 1DX and 5DMKIII.  Combinations of new and old still AF marginally.  It is suspected that the new cameras and new lenses may have closed the loop on AF so accuracy and repeatability is much better.

All this negativity about advancement in technology!!! Why??
There WILL be a high mpix camera anyone likes it or not.
There WILL be people who will buy it as it will promise better IQ...

We should not fight this and just wait to see if it suits our needs. If it does we will buy it.

I am looking forward to it in a 1d style body... But that is ME.

If you shoot video though HTP can be a big help when the scene changes.  Though shadow noise is a problem, it's a bit less obnoxious in video as is blown out highlights.

HTP increases the DR if you shoot in JPG.  It underexposes by 1 stop of ISO, then lies about it in the metadata (that's why ISO 200 becomes the lowest setting - if you shoot at ISO 200 with HTP, the camera actually exposes at ISO 100). That 1-stop underexposure preserves a stop of highlights, the camera then applies a tone curve to boost everything but the highlights by 1 stop (meaning a stop more noise in the shadows).

If you shoot RAW, leave HTP off.  You then have latitude to preserve >1-stop of highlights, and can apply your own tone curve.

444
We would need some better lenses for that.  500 and 600 mk II would need some upgrading.  You will find your shots also get softer.  Not because of the camera but because you are pushing the limits of the lens too far.

when I here 40mp as a wildlife shoooter   I here  croping into my shot by 60% and still have'n something to work with !  bring it on

445
The only purpose a larger MP camera will serve is to provide either smaller pixels or to allow for deeper cropping when necessary.  Size and print enlargement are irrelevant unless you plan on printing full frame shots as wall murals.

That being said, there could also be other benefits such as better AF system, less noise at high ISO and better highlights.  Could we see a 16 bit DR with this one?  We'll see.

Based on pixel density alone, most will never have a need and all will never want to have to store such large images forever.

EOS Bodies - For Stills / Re: Overly Hot Hotspots On 5Dmk3
« on: March 25, 2013, 03:13:30 PM »
Have you tried HTP (Highlight Tone Priority)?  On the 5DIII this works with stills or video. Compresses the DR a bit for just such an occasion.

BTW, the 5DIII has excellent DR.  14 bit compared to 12 bit on earlier models.  For video, wide DR will usually get you into trouble when you start editing your clips and compressing for DVDs.  HTP will get you closer to that compressed DR needed for video work.

Hello all! This may have been addressed before so forgive me, but I'm just curious to see if anyone is noticing this on their 5Dmk3's.

I understand the 5Dmk3 doesn't have the best dynamic range, but does anyone else find hotspots to be overly hot? As an example, I was camera op on a short film the other day, and both the DP and I agreed to move to the 5Dmk2 simply because some of the things (i.e. lamps, televisions) were so drastically hot and were overexposed, where on the 5Dmk2 they were near evenly lit.

Also, I was walking around the park with a friend who had a 7D, and after comparing shots the shadows were much, much harsher on the 5Dmk3 at the same exact ISO, aperture, and shutter speed as well the whites being much hotter.

Now don't get me wrong, I love my 5D and have been blown away with it at times when I'm able to control the exposure of the subject, but I'm not really understanding why everything is so blown out at times. Is this a user error, camera error, or not an error at all and just how the camera handles?

Thanks, and I appreciate any responses.

It can be useful but does have an impact on drive mode frame rates.  I can see where it might be more useful with video than with stills.  If you do try it for a wedding, be mindful of blowing out highlights.  especially if you are used to shooting with it on all the time.  :)  It may/will increase your dynamic range.


Wow! I've always shot with HTP on. I guess I just assumed it was better for weddings to have it since the bride is (almost) always wearing white. Very interesting. I might have to try shooting next week's wedding with it off for a change.

Another 3000.00 out of pocket. :(

7DII having more pro features. ?

Such as ?

Tack Sharp is maybe not what you really meant.  You can sharpen edges to fool the eye and make it "appear" sharper on the edges.  Probably what you meant is getting the highest resolving power to reveal finer details.  This is more about the quality of the lens for a particular purpose rather than specifically about cameras.  Most modern cameras are capable of resolving fine details.  Full frame more so (and also able to reveal the faults of a fine lens).

There are sites that test and review the resolving power of optics.  If you are looking for the finest detail then you need to be selective on lens choices and even then compare multiple copies of the same lens as there are differences and some of the differences are striking.  Always good to check.

Also there are other factors to consider too.  While a lens may test at a high resolving ability, if it suffers from chromatic aberration it's going to be difficult to achieve what you want as eliminating the CA will also eliminate some of the color that reveals the finest detail.

Here is a good site that lets you compare various lenses to see which ones resolve more detail and which ones suffer from CA and how much.

So, a friend and I have been on this quest to shoot a photo like we have seen online countless times or in video training etc.  Its where you take a picture of a person and even when you zoom into it at 200% the clarity of the image and sharpness is just off the charts.

We have tried everything to replicate this level of sharpness and just cant.  Locked off on tripods, cable release, etc. Its just not working.

Are we expecting too much out of our gear?  We are both rocking Canon APS-C (7D, 60D) with good glass 100mm F2, 50 1.4, Zeiss 35mm F2, 25-105 F4.  It just feels like we are missing something somewhere because our expectations are to take pictures like scott kelby or joel grimes or someone where the sharpness even zoomed in is amazing without a bunch of post processing.

HELP!

Better yet, rent a 60Da to see if it suits what you need.  Lots of other issues crop up as a result of removing the filter.

Sorry if this sounds obvious, but are you applying decent output sharpening when you are finished editing the photo? The AA filter on Canon is strong and sharpening is required for enhancement of the details.

There is another option. If it is critical to the OP can have the AA filter removed. I have contemplated getting a used 20D and trying it just to before destroying any new camera I have but have never gotten around to it. I doubt I ever will.
