EOS Bodies / Re: More Images of the Canon EOS 7D Mark II
« on: September 13, 2014, 08:23:15 PM »
Just small incremental upgrades.  Not much to show for all the years of development if you ask me.  I'll skip the mark II, thank you.

Since I skipped the 30D, 40D, 50D, 60D and 7D, this looks like a huge upgrade to me over the 20D I shot with (very successfully) all day today.

I'm shooting with a 60D and it looks like a huge upgrade :)

My biggest question is, should I get a 70D or a 7DII?  Some advantages for each.  I'll wait for the announcement and first tests on the sensor of the 7DII before I make a decision.

Interestingly, I was considering between 70D & 6D versus 7DII & 5DIII.  I like my 20D and 5D because they basically have the same user interface.  But, for what I use it for, the 6D would actually probably be better than the 5DIII (WiFi would help at times, GPS would certainly help to keep the clock accurate, the low-light focusing point is probably more useful for me than the 5DIII's advanced super-fast focusing).  So my wife basically told me to suck it up and get the 7DII and 6D, and just learn to handle the UI differences.  Still thinking about that, but she probably has a point.
At the moment, we don't have a clue if Canon has addressed the noise problem or not.... I give it 50/50 odds. Rumours say a new sensor, yet at the same size as the 70D. It is possible that the 70D sensor was the first "kick at the cat" for an APS-C sensor with finer lithography and that the 7D2 builds on that sensor and adds in cleaner A/D... It would certainly make sense, but it is just a guess... We should find out in a week or so.

EOS Bodies / Re: A Surprise Cinema EOS Announcement for Photokina? [CR1]
« on: September 13, 2014, 08:09:22 PM »
I am fairly certain that there won't be a big Cinema EOS Announcement for Photokina.
IBC is going on right now(where Sony announced the FS7) and it is really the most likely to place for such an announcement.
The FS7 is interesting movie from Sony. If I had already invested in a F5/F55, then I would feel slightly pissed.
Nothing stops them from announcing it in two different places.....

I'm probably going to get one just for the AF system. Any other improvements are gravy :)

EOS Bodies / Re: Digic 7 Development
« on: September 13, 2014, 11:10:43 AM »
This new processor is the key to high MP cameras.  Doubling the resolution will require 1.414 times the processing power.  The current Digic 6 will drop the 1Dx to 8FPS.  The Digic 7 is going to be a dual Digic 6 in one package which will allow 4x the processing power for high MP, high frame rate bodies.

Canon normally has 4 versions of their Digic Processors, the + version for the high end bodies.  I thought that the upcoming 7D will be the first to use the Digic 6+.  Why would they put a Digic 6 meant for low end DSLR's in a 1DX?  When the successor comes along, it will have two Digic 6+ processors, which will be appearing in cameras starting with the 7D MK II.

Do you have some facts?  Reference?.  Test Results? 

I'm not sure what to think of the comments, and your information about the make up of the Digic 7.

Canon uses ARM processors that are custom packaged for them and giving a Digic number.  Nikon, Sony, ...everyone does the same thing.

The issue is to get processing power with a low power usage.  This means that the fastest processors may not be used due to power consumption.
A lot depends on the architecture. You typically need computing power for short bursts, so a common trick is to use variable clock rates and to shut off cores under periods of low need. With the slower clock the devices use less power, and shutting down cores does the same. For example, perhaps the various cameras with dual digic processors normally run on one chip and only enable the second when you press the shutter....

Exactly, but not all ARM devices have the same power efficiency.  As new more efficient devices appear, they will be the candidates.

The Cortex versions seem to be the low power champions currently, but reducing the current 28nm process can reduce power / performance.

I notices a announcement that a new snapdragon processor will use the ARM Cortex A7's.  Its a lot like digic, it uses ARM processors plus more custom processors and firmware to accomplish a specialized task.  I'm not sure how the power usage compares with a DSLR, but I expect it consumes a lot of power.

agreed!
I would suspect that it is lower power for some tasks and higher power for others. What the net effect is would be anyone's guess, but since it is developed for cell phones, my bet would be lower in power overall.

I don't know what the video/still ratios are on smartphones, but I suspect that the video demands are far higher than on a DSLR... after all, video runs all the time, even when taking a still picture. I don't know, I/m just guessing.

EOS Bodies - For Stills / Re: Post your 'Noise by Ten' results
« on: September 13, 2014, 10:59:52 AM »
Thanks for killing what could have been an interesting thread to post items that could increase knowledge and understanding, and which, also, could have been a way to keep DRones and trolls from posting in topics that are far far away from needing overly lengthy elaborations.

The subject has been beaten to death, the topic should be killed.
What this shows is how signals are amplified inside the camera. ISO's like 160, 320, and 640 are the base numbers. An ISO like 200 is gotten to by digitally multiplying the signal.... and to do that you are LOOSING the accuracy of your sensor.

An understanding of how your camera works is usually a good thing. Yes, the information is already available in charts on various sites, but what is wrong with experimenting with your camera to see what happens?

I'm really torn.  One group that I talk to is saying that the 70D was only a marginal upgrade over the T2i (that I currently use).  They're also saying the 7Dii is going to probably only be a marginal upgrade as well.  I bought the T2i years ago when I was first learning how to shoot.    But there's a lot of people on this forum saying the image quality would be massively improved over the T2i if I switched to the ii.   

I'm photographing mainly wildlife, about 85% of what I photograph is birds, smallish ones.  In actuality I'm only using the center focus point probably 90% of the time as well, since I'm good at getting in the range of my 400mm, and it's close enough that the center point covers most of the bird.   

May skip the ii, and maybe go to a 5diii or 6d or something, since I'm not hurting for reach in the least.

The truth is usually somewhere in the middle. You will see an improvement in image quality with the 70D, it will definitely be noticeable, but it will not be earthshaking.... but the user interface is drastically different and according to those who have gotten used to it, much better.

As far as AF goes, yes, the 70D has far better autofocus, but if you just use the center point you will miss most of the advantages. What you will see is that the AF on that center point is more accurate and of course, if you go into live view, the DPAF is a huge improvement..

As far as the 7D2, nobody knows..... until people get their hands on it, you are just hearing guesses and opinions based on rumours and startlingly devoid of facts.

And doubling the resolution SQUARES the computing demands... you need 4X the computing power.

I will be excited when it is over.
LOL, but then it's another 2 years of painful anticipation...
NO! Not two more years to wait for the 7D2!!!!

« on: September 12, 2014, 05:36:01 PM »
I really don't understand what the fuss is about....

Seems to be a love-hate relationship with Canon :-o ... I certainly have one since I bought my first film camera (eos 620) in the early 90s. Canon is smart and keeps designing their products so people shell out a lot of $$$ while still wishing for more. Plus photogs in general seem to be quick to adopt a smug, know-it-all attitude, after all you're the one having the power and pressing the BUTTON :->

What we have here is someone wants some aspect of their next camera to be better than what they have now... WHY ARE YOU PEOPLE ARGUING!!!!!

To some extend, I can understand both sides and thus can skip reading: Until I kept using Magic Lantern's dual_iso module (nearly 15ev dynamic range on the 6d) I didn't miss anything and kept bracketing. If you don't shoot higher dr scenes or are simply are used to 10ev, it's easy to perceive others as trolls. But higher dr is big news, it means less hassle with exposure and more freedom for shooting scenes that were out of scope of photography some years ago.

To be ot: Personally, the rgb metering is the most interesting news to me - it also means better exposure = more of the dr used = less noise. Strangely, this innovation seems lost in the thread.
I still don't understand the arguing.....

Take Jrista as an example..... he wants more DR and less noise in his images.... The thing is, we all do. If the 7D2 came out with 20 stops of DR and almost no noise, would anyone refuse to buy it because Canon made it too good? Of course not.... but we would expect even more from the next model out. We always want more, and if the other guy already has it, that just makes the desire stronger.... So why are people arguing? Shouldn't the reaction be "me too" and then the great debate ends?

PowerShot / Re: SX-60 coming at Photokina!
« on: September 12, 2014, 04:30:51 PM »
.
I'm guessing that 2000mm is with digital. I'd be surprised if optical zoom went beyond 1200mm.

Either way, I'm probably going to get one. Looks like lots of fun, and the images I've seen are more than adequate for what it is. What will my old S95 say?

The SX-50 already has a 4X digital zoom for "4800mm"....

One of the more interesting rumours is:

The Powershot SX60 HS IS will be the replacement to the popular SX50 HS model and may come with the new DIGIC 6 processor, a 15MP sensor and a 20-2000mm focal length capability 100x zoom lens.

PowerShot / SX-60 coming at Photokina!
« on: September 12, 2014, 11:35:53 AM »
The latest rumour is that the SX-60 is coming to photokina.

The SX-50 works surprisingly well.... but what changes will come on the SX-60? A larger zoom range is a given... I have heard rumours of 60X and 100X... but does anyone know what the specs are supposed to be?

DPAF would be a killer addition, but I doubt we will see it. Wifi? Megapixels? anything?????
