Canon General / Re: A Rundown of EOS 7D Mark II Information
« on: August 15, 2014, 09:38:29 AM »
I think that the 7D MK II (with those specs) will fill the gap that the 1D MK IV left. The 7D could not fill that gap and wasn't targeted for that. But the 7D MK II will outperform the 1D MK IV and is able to fille the gap. Those that are not able to afford the 7D MKII will go for 70D or the successor of the 70D. My personal believe is that this spec game of Canon is done to take photographers to the next higher performer camera as part of sales strategy. It happened at least with me going from 550D to 7D to 5D MKIII  ;D

If they price it too high, then a lot of people that have been waiting for it will go buy a 70D instead.

Sounds like an excellent marketing strategy to me.  ;)

Regarding the 'EOS 1 build quality', that's carefully phrased.  It doesn't say '1DIV' or '1D X'.  It's technically correct to say the 5DIII has 'EOS 1 weather sealing', since Canon called it equivalent to the EOS 1N film body (but that's not up to the level of the 1D X).

So Canon only has one EOS-1 series camera in their lineup now.  If they say EOS-1 build quality it should be on "par" with the 1DX and not the 5DIII.

man, if half of that spec list comes true, and the launch price is $2k or less, I'm going to have a hard time waiting for refurbs to show up...


With the few rumored specs here this may be top of the line camera with an APS-C sensor that will target semi-pro and pro. My expectation is that the price will be in the same league as the 5D MKIII at launch.

When it was launched, though, the original 7D was exactly that, was it not? And it was $1799? Not saying it couldn't be as much as the 5d3, just that I don't think it necessarily will. I'm certainly not counting on $2k, but I'll be disappointed if it's north of $2500. Time will tell!

A couple of things that have been leaked will likely send this camera into the 4K range:

EOS 1 build quality
EOS 1DX type features

Those two bits of info are far better than the 7D ever was...

I would argue that the 7D had similar build quality and features to the 1DIII, which is what was out at the time the 7D was announced.

No I dont agree that the 7D comes close to the 1DIII in build quality.  There are fundamental differences in many areas which separate the two.  Shutter and sealing are good examples. 

Much of my cost basis is based on the fact that Canon has nothing in the EOS 1 lineup now other than the 1DX.  There is a very large gap between the 7D and 1DX.  I wouldn't be surprised if it ends up being called the 1D mark V.

Those two bits of info are far better than the 7D ever was and while it comes close to the 5D3, the EOS 1 build quality will definitely demand a premium.  Consider this in the price range of the 1DIV with an inflation adjustment.

I'm guessing 3500 to 4200 for the body and leaning toward the upper end just because Canon will start out milking us for the R&D costs up front as they always do.

Very glad they omitted the touch screen and wifi.  Both just add extra cost, run down the battery quicker, and are pretty much useless IMHO.  If you need wifi, get an eye-fi card.

I still see this thing retailing at about 4-5K and will likely be bundled and offered first with a brand new 2800.00 lens.

There goes the price point then.  Early on everyone was expecting about a 2000.00 price point but lately with the talk of 1Dx type features and now the removal of Wifi, this body will likely be in 4000.00 range and Knowing Canon, I really expect it to be closer to 5000 or 6000.

Like another person pointed out, this will likely force a lot of people back down to the 70D.

No doubt however, this one will be an excellent model and look forward to depleting my account and any hope of getting that new Dodge Hellcat.

And the REALLY bad news is that it will probably come bundled only with the new 7D replacement for preorders.  So we are looking at an initial kit purchase of close to 7000.00!!!

Good God!  2800.00?  Must have added more Gold and Fluorite.  It's probably overpriced even at 1400.00

Third Party Manufacturers / Re: DXO uh-oh?
« on: August 06, 2014, 12:11:07 AM »
As DXO has given a near perfect score to the D810, they may have painted themselves into a corner. Their proprietary scale doesn't give DXO much room to heap hyperbolic praise on the next Nikon release.

http://nikonrumors.com/2014/07/24/nikon-d810-sensor-new-dxomark-leader.aspx/

This really isn't a surprise. DxO and Nikon are inseparably joined at the hip. Plus, all this really means, particularly the new 14.8 stops Print DR number, is that Nikon is cooking their RAW files EVEN MORE. Nikon/Sony's biggest "cheat" is the fact that they clip to black point, instead of offsetting to black point. Nikon cameras just throw away a lot of low-level signal information. The Sony Exmor sensor gives them more room to do that, for sure, but they are still throwing away information.

Canon, on the other hand, does not clip, they offset. So ALL the noise in the deep shadows of Canon's signal is still there (it's always there, in every sensor). Canon could probably achieve better results by using a more significant offset...and at times, as they have improved their sensor tech and increased their bit depth, they have changed their bias offset. It used to be 128 to 256 back in the 10-bit days, it was 512 to 1024 in the 12 bit days. I think it's 1024 or 2048 with 14-bit cameras.

The kicker is that RAW editors don't have to honor Canon's bias offset. The entire RAW signal is stored in Canon's files, and the offset is calibrated with a border of masked pixels. Who knows if editors like Lightroom, or DXO, or Aperture actually adhere to Canon's recommended offset. Even if they do, there is still negative signal information that can be pulled up, and the full noise signal is there. With Nikon RAW images...all that negative (deep noise) signal is simply discarded.

I use DeepSkyStacker and PixInsight to calibrate Canon RAW files for integration into a "stack". I use a 200-frame master bias image to subtract the bias signal from each light frame before integrating it. When the bias is removed from Canon RAW files, the dynamic range jumps by almost two stops...which puts it in the same range as Nikon files...

And still another way is to use magic lantern dual iso...which will enhance the DR of even an old canon camera...and its free.  Would not spend 3500.00 on a new body just to get more low iso DR and a few more MP.

I thought it was pretty well known now that the indicated ISO speeds on digital cameras are not consistent even from model to model from the same manufacturer. So for example ISO 100 on a 6D is actually 80, on a 5DII it is 73, and on a 5D 92.

This can be confirmed with an accurate hand held light meter. Set the meter to 100 and you get an under exposure of one third to two thirds depending on the camera you are using.

We can thank DxO for this information.

So to accurately measure that difference your really need to use the same lens.  Different lenses even if they are all F2.8 have different light transmission qualities.  The F2.8 is not an exact standard of light transmission.  For example an F2.8 prime will likely have better light transmission than an f2.8 zoom due to having less optical elements.  This difference is measurable.  The same holds for ISO measurements.  If you are not testing apples against apples then you cant really make the claim that ISO varies significantly when it could be the optics that are skewing the results.

This is particularly true when comparing different brands and sometimes models within the same brand if they have integrated optics or different sized sensors.

Lenses / Re: Soccer and Football IS Mode on 300L
« on: August 03, 2014, 10:39:27 PM »
I have great success with using IS mode 2 for Soccer and Football.  Mode 3 should work as well but there is not any benefit.  Mode 2 lets me hold focus better on the players faces.

I have taken shots extensively with and without IS enabled. As long as you use a fast shutter speed, the image will be frozen.  No difference in IQ with or without.  Note, I only use IS to allow me to hand hold and maintain a tight focus on the players faces.

Otherwise generally no need to use IS for sports.  Mode 3 wont help you hold the focus point as it activates only when the shutter is pressed.

EOS Bodies / Re: One other hoped-for feature on the 7D2
« on: July 29, 2014, 07:47:21 PM »
on the 5diii and 1dx you can program the set button to activate ISO on one of the wheels.  Forget auto ISO since you will ultimately get more noise than you want.  Use full manual and adjust ISO with set button and top wheel.  I've even learned to fire the shutter with my middle finger when speed is of the essence.

Software & Accessories / Re: Rain protection for 5D3 and lens
« on: July 14, 2014, 02:10:44 PM »
I have a 5D mark 3 and use it for airshows with a 70-200mm f2.8L IS II or a Tamron 150-600mm f5-6.3.

Looking for some rain protection that will cover both lenses (whatever one is attached at the time) and the body as I often have to shoot in rain and don't want the camera and lens getting soaked.

Any suggestions without breaking the bank too much?

In the past I have relied upon the "wife+umbrella" technique but wife will be missing from the next few airshows!

Cheers
Scott

I too have bought a number of rain covers...cheap and expensive.  For the 5D3 and weather sealed lenses, I now just use a towel or two.  Throw them over the lens and body and roll with it.  I've used that many times shooting soccer games.
 
If you end up being in a real gully washer, your not going to get much in the way of pictures anyway and thats the time to bag it or pop open the umbrella and wait it out.  Gotta dry it all out too before long term storage...no caps in this stage.

EOS Bodies / Re: The new APS-C Champ. (My wild guess).
« on: June 23, 2014, 10:35:10 PM »
Since most of the rumors coincide with “new” sensor technology, and significantly lower noise; My guess is that Canon has further evolved the Dual /( Multi) CMOS technology to acquire more light, while maintaining resolution???

Perhaps distributing pixels over multiple sensors, with a method of acquiring “even” light to each sensor element.   ( The only “current” manner of lowering APS-C noise is to reduce resolution/pixel-count.

Canon has a history of “field testing” new technology in lower priced cameras, hence the 70D.

I do expect that the 7D MK II will be a big improvement over the mk I. 
I do not expect more than one sensor in the camera, why would they use multiple sensors?
 
You cannot acquire more light by splitting a pixel in pieces, they gather photons according to the area, so you receive approximately the same number of photons overall.  The 70D does not acquire more light, but uses the dual pixel for phase detect autofocus.  Otherwise, its the same as other Canon sensors.
 
The split pixel technology potentially allows some other tricks like improving DR, and probably some that I'm not aware of.

Maybe dual sensors could be used, but not for what you think.  I could see a use to have multiple sensors, 1 for imaging, one for AF, one for the hybrid viewfinder (or maybe a dual pixel sensor that can perform AF and feed the hybrid viewfinder.

I would be willing to bet that the new models will just do away with the phase detect sensors that we know and have loved for all of these years.  A better full time contrast detect with higher speed AF with focus points anywhere across the sensor field.  Higher end models would be fully programmable on AF patterns.  Lower end would be fixed patterns.

We have already heard rumors of the 7D replacement having a larger "bump" on top.  How about a specialized prism that can split the image into multiple paths to multiple sensors.

It just seems to be the next logical progression from the dual pixel technology.
