EOS Bodies - For Stills / Re: Backup body for extreme environment
« on: January 31, 2015, 11:15:56 PM »
hi everyone, I'm going to be living and working in Antarctica soon and I'm looking for a good backup body to take with me. My main body is a 7D mark I which I love and has pretty much everything I need.

I have used my 7D Mark I in nearly every extreme circumstance there is:

Temps at -14°F through 102°F (-26°C - 39°C)
Howling wind at over 60mph
Rain
Sleet
Snow
Hail
Fog (w/ sealed lenses)


I've dropped it a few times, even. I haven't actually used it literally in a hurricane, and I haven't used it at -50 near the north pole shooting Aurora (yet. :P) I've got over 100,000 exposures on it at this point. Personally, I think most cameras these days can handle the extremes pretty well, if they are properly sealed. I'm not really sure how much the various different "levels" of sealing matter...I know some brands tout better sealing than others, but my 7D doesn't have top of the line sealing, and it's still pounding away, a dedicated workhorse.


I would be looking to use the camera for a range of uses across various environments (at sea, Falklands, peninsula, mainland continent, icebergs, low-light, astro, birds etc.) and would ideally need to be weather sealed and cold weather tolerant (-55 Celsius).
I'm going to be down there for 18 months so although my main body will be used most, it is a long time and all gear breaks, there is obviously nowhere to get it fixed/replaced should I need to.

The ONE thing you might have trouble with is shutter actuation and battery life at -55°C. My 7D gets fairly sluggish and sticktion-prone at -25°C. I haven't noticed that yet with my 5D III, which has been used in similar cold. Batteries also get pretty sluggish in the cold. Weather sealing wise, I think you'll be fine, but you might want to see what the pros who shoot penguins and such at the Falklands do about that. Some mirrorless cameras with electronic shutters wouldn't have the shutter problem, but the battery problem, that's likely fairly universal.

EOS Bodies / Re: Where is the EOS 5D Mark IV? [CR2]

And we all know that Canon doesn't design products that internally could be seen to compete.

Well explain the 5D MkII that killed the $7,000 1Ds MkIII for all but a very few purchasers, or the 70D that must have had a big impact on 7D sales.


Well, I don't know what Canon's thinking has been. However if we look at the camera lines since the 1Ds III. Canon merged the split 1D line into a single line with the 1D X. They released a single 5D III that seemed to fill a different, and higher, position and price bracket than the 5D II. They released the 6D. They are now apparently releasing the 5Ds and 5D IV as a split line, again fitting into what appears to be that higher position in Canon's pro-grade lineup.


The 70D came so long after the 7D, with the 7D II not all that far behind. Perhaps Canon simply did not care about the ancient 7D classic at that point?


Perhaps their intention all along was to kill off the 1Ds and replace it with the 5Ds. Companies like Canon always have big, long-term plans.

Has anyone considered that the DSLR market may simply have become saturated? Every market has a saturation point, where a majority of potential buyers already has one of whatever it is being offered (ILCs in this case). Canon wants their users to turn around and buy a new DSLR every 2-3 years (for high end stuff), and based on their release cycle, every 1-2 years for the low end stuff.


Economies, despite "recoveries", are still tight for most middle class workers, and have always been tight for lower class workers/the unemployed/welfare. That lowers the saturation cap, and reduces "replacement/upgrade" demand. I don't think people want to or even can replace their cameras every couple of years. There is also a threshold of quality...ILCs are pretty high quality these days, in terms of build...materials, ergonomics, fit and finish, feel, etc. I think people are less likely to replace a great device as often as a cheaper one.


I can totally see P&S sales being stolen by smartphones and other mobile devices with cameras. I can even see some of the Rebel-level sales being stolen as well, although not nearly as much. It seems more likely that the ILC market (at large, not just Canon) is reaching or has reached a saturation point. It's already a global market, unlike smartphones which still have expansion potential in newer economies like China and India (where there are potentially billions of customers), so I don't know if there is a lot of room for expansion. The market will probably settle, find some kind of equilibrium with new buyers from new people (young families, new photographers, etc.), replacement buyers looking for an upgrade or to replace a broken camera, etc.


If some disruptive new technology finds it's way into consumers hands at some point that can produce high quality images, then the ILC market would then probably slide into a long term decline. Dunno if/when that might happen, though.

If it does 8fps @ 28mp

Unlikely as it is too close in speed to the 1DX?

And we all know that Canon doesn't design products that internally could be seen to compete.

EOS-M / Re: EOS M3 24 MP Sensor?

Image quality can be objectively measured. It's been demonstrated for years that those measurements do have a bearing on IQ. (I'm not talking about DXO scores here, either...I'm talking about measurements.) Not necessarily in every single image, but that's not what we're talking about here. We are talking about the potential to produce quality images...as it is an image producing device under discussion.


Objectively speaking, the device is either more or less limited in it's ability to produce quality, on a RELATIVE SCALE of cameras currently available. Canon's high read noise puts it at the lower end of that scale.


When it comes to what image quality is dependent upon. Let's list the criteria:


Sensor
Readout System
ISP (Image Signal Processor)
AF System
Metering System
Lenses


The user is a factor, but let's exclude that for the moment. Canon lenses? Awesome. Canon metering system? Excellent. Canon AF system? Excellent. Canon ISP (DIGIC 6)? Highly competitive (NX1 may trounce everything, though. ;P). Readout system? Hmm. Sensor? Hmm.


Canon excels at everything else that affects image quality except their readout system and sensor. Therefor, it stands to reason that the sensor and readout system would be the area Canon should put their focus, no?


So what's involved in an image sensor and readout system? Electronics and signals. What do electronics and signals have in common? Noise. What can be done to improve the quality of the signal coming off the sensor? Reduce noise. What does reducing noise do? Increases tttmnbso*. Oh. Oh. Ooohh!


There isn't anything else to it. Signals and noise. That's what an image is. In an image, a reduction in image noise increases SNR. In a device, a reduction in read noise increases tttmnbso (which is the potential for the camera to produce quality).


I'm trying to keep things objective here, not subjective. With objectivity, we have a level playing field. It doesn't assume one person's perceptions or opinions are better or worse than anyone else's....it simply relies on the cold, hard, emotionless little facts. It's a device we are talking about, something that has POTENTIAL to create images of quality. That potential can be higher or lower. Sony, Toshiba, Samsung? The potential of their sensors (just sensors, readout systems are included on-die & not all of them actually have cameras) to produce high quality is high to very high on a relative scale. Canon? To date, the potential of their sensors and readout system to produce high quality is lower, on a relative scale.


Emotions and perception doesn't play a role here (or at least, shouldn't play a role.)


Well, that's all for now, folks!

I don't really need anything more than the 5DIII, but I'm going to start saving in case this has Sony-like DR.  Instead of getting a new release 2-3 years after the release, this might just be one I get quickly.

My hopes:

24-28 Mp
4k video
8fps
Sony-like DR at base ISO (no banding etc...)
$3500

That would definitely be enough to get be buying quickly.  Even with 22Mp and no 4k I'd jump on it.


If it does 8fps @ 28mp with the iTR AF/meter along with really low noise, I'd buy one. I'd pre-order one, and I never do that. That would make it an AWESOME FF action camera with an extremely good frame rate and tons of resolution that could then easily double as another AWESOME FF landscape camera with extremely good tttmnbso*. That would also mean it would compete pretty head on with the 1D X...which is why I don't see the 5D series getting a truly high frame rate AND great tttmnbso yet...

I really don't see Canon using Sony sensors. It just doesn't fit with their long established business model, nor the pride they take in their top to bottom integrated product lines. It'll be a Canon sensor.

I agree.  A couple completely unsubstantiated rumors and people are going gaga.

And the idea that Canon does not produce competitive sensors is rubbish.  Yes, the Sony sensors have better DR at low ISO.  If that's your number one priority, then go for those Sonys or Nikons that use the same sensors.  By many user accounts, the sensor in the new 7DII is producing excellent results in every other area but low ISO DR.  The Canon sensors are slightly better at higher than 800 ISOs - and, in my opinion, produce more pleasing color and contrast - especially skin tone color. 

I think the basic problem with Canon and mirrorless is that those seeking mirrorless have many other choices - and have probably already bought a competitors model.  I know I have (Olympus).


It's not that Canon does not produce competitive sensors. Never has been...at least, that's not been my perspective.


The notion is that Canon cameras do not produce as competitive IMAGE QUALITY. There is a difference. Their cameras are great in most respects. Their use of off-die high frequency ADC units decimates the quality that their sensors are capable of. That's the problem. But Canon cameras are plenty good, their action capabilities are often unparalleled, and their lenses are top notch.

..person and one  in a micro minority looking at the specs.

I need...

Excellent DR and low ISO performance. Will be using it for Landscape/Portrait and Macro work.

I do NOT need..

Video capability-4K or 444K
High ISO
WiFi
GPS
Very high frame rate

All I care about is a still camera with so far unseen still image quality in 35 mm format  for the work I mentioned above.

I  will buy it even if it breaks me. Will work many more extra shifts but will enjoy it immensely.

Thanks Canon


Aye, I don't need much for a landscape camera. Would probably make for a nice macro camera as well, true true. All I care about is getting the best RAW image quality possible. Resolution certainly plays into that, but noise does as well. At 50mp+ they are certainly not going to have any problems on the resolution front. That leaves noise...and I REALLY hope they worked their asses off on the noise front.

Can we just say "Voldemort" instead? Thats seems a lot easier and means exactly the same thing


"Voldemort" implies unmitigated, unfettered evil....threfor, they don't mean the same thing. :P

...so that leaves read noise. If they don't do something about that, then it doesn't matter how much Canon improves color purity or how much they limit high ISO settings...they still won't stand a chance against the D810 or any of the MFD cameras using Sony's 50mp MF sensor.

Lol.  The 5Ds won't stand a chance against MFD cameras...with their industry-wide annual sales of less than 10,000 units?  Ummmm...sure.  Or maybe you meant 'won't stand a chance' of getting a higher DxOMark Score, and about that you're correct.  But so what?


"Won't stand a chance " in terms of image quality. God, the amount of excessive qualification required here is unbelievable. Time to go back to my astrophotography forums where people are smart enough to get the implications without it all having to be spelled out.  ::)

The number of morons attacking this camera for not having higher frame rates, 4K, or higher ISO is pretty amusing.

This is the camera for the rest of us who have felt ignored by Canon in its rush to Video. Studio and Landscape artist have been staring at the Nikon 8xx and the Sony A7r with sad eyes as they went out to shoot with their Canons. My concern is price. I might consider this but Weight and size is impacting my older arms. For this reason I am likley to go to the A7II and the soon to be announced A7rII or A9.

For those of you complaining wait for the 5DmIV -- that will have higher frame rates, really high ISO, 4K, at around 24mp (my guess). I think that one will have a SONY/Canon sensor that Nikon will not get.


Absolutely. This is (hopefully, pending tttmnbso* results) the camera I've been waiting for to become my Canon landscape camera.

But, this has explicitly been stated as a low ISO performance camera...

Where?  It hasn't even been announced yet!


In the rumor itself. Also implied by the "s" in the camera model name.


Quote
...and with all the articles from Nikon wedding photographers talking about the ability to shoot without flash (which is often a critical thing for wedding photographers, as flash can be disruptive to ceremony and whatnot), low noise in general is a bonus for a camera like this.

Low noise, yes, but do you know how many base ISO shots I generally take at weddings?  Almost none.  Most are ISO 800 and up, and that's where losing a stop to stronger filtering in the CFA will be a huge loss of performance.


Well, I guess it's a darn good thing you already have Canon cameras that perform great at high ISO then.  ::)
