CPN on CANON 7D MK II

Mt Spokane Photography said:
The thing I find interesting is the date of the shots, which supports my theory that Canon was building 7D MK II's as early as last spring in order to have a big supply, and perhaps to allow shifting of production to the next DSLR model.

I've seen production numbers in the range of 30,000 a month quoted by Canon when the 7D came out, and having 200,000 ready to ship to dealers in Mid October means starting in April more or less. That could mean that the next DSLR is likely now in production for deliveries in March 2015.

"Thorsten was given two days in July to photograph the five-week old white lion cubs for Canon ahead of the photokina show (where the EOS 7D Mark II DSLR was officially launched) in September. His 30-minute late-evening sessions would have been sufficient for a portrait shoot or perhaps ample for a product shot, but when your subjects are supercharged bundles of fangs and claws, there is never enough time.

Thanks you , Sir, Dear Teacher Mr. Mt Spokane Photography.
you are right on the target :l
Canon is a super smart company to do like you said = Make a lot of Money to sale the New Product, and have a early production,/ FIELD TEST = to make the minimum mistake of New products, when on the MARKET FOR SALE.

"That could mean that the next DSLR is likely now in production for deliveries in March 2015." = Dear Teacher, I hope that Canon 3D with 36 MP will come during Spring 2015----And My money will be support Canon co. again like this time , my new toy 7D MK II.
Have a great weekend, Sir.

Some questions about autofocus speed

fishprof said:
I’ve been lurking here for quite a while and have been learning a great deal from these discussions. I have a few questions about autofocus speed and the relative importance of the lens versus the camera body. I shoot a 7D and I’m primarily using one of two lenses – a Canon 300mm f/4 L with or without a Canon 1.4X TC III or a Sigma 150 mm f/2.8 macro with or without a Sigma 1.4X TC. I shoot mostly wildlife, primarily birds, and macro, especially butterflies, dragonflies, and other smallish nature subjects. I shoot about 50% hand-held, about 50% monopod mounted and I almost always use the central autofocus spot on static subjects. My vision is not very good so I rely almost exclusively on the camera’s ability to autofocus my subject quickly and accurately.

Nothing wrong with relying on camera's AF. That is what it is for! And when shooting 10fps there is no way to rely on the eye to judge focus.


1. I have a sense (but no real measurements) that the addition of the TC to either lens slightly slows autofocus compared to the “naked” lens. Under identical shot conditions and lens/camera settings, is there a reason to expect that addition of the TC would slow autofocus lock? Maybe it is just my imagination?

Yes it does, Neuro has given you the math.


2. I’m thinking about upgrading to a 7DII next year. Will the new and improved autofocus system in the 7DII make a difference in improving the speed of autofocus acquisition with my current lenses? In other words, given identical shot conditions and camera/lens setting, will the 7DII be faster to autofocus than the 7D or is speed going to be limited by the lens system I have in use?

Faster maybe. How much faster? Very little. But overall it will be much better focusing device: Tracking, spread out better focus points etc.

3. I have heard it said that the image stabilization (IS) system actually slows down autofocus lock. One suggestion I have heard (or read somewhere) is to turn off IS when shooting birds-in-flight to allow the camera to lock focus more quickly. Is there any truth to this?

Don't think so. But even if it was, it would be so little that it does not matter.
All are unscientific personal thoughts. :)


Thanks for your help.

Roger Cicala cracks open 7D II!

dufflover said:
Def agree that the toughest and prone forms of weather damage are ones that no sealing can really protect like internal condensation from swinging temps.

actually......

I just installed three Panasonic cameras.... they have a heater to keep the inside warm on those cold winter days and they have a mini dehumidifier to keep condensation under control.....

But I certainly would not bring one of them on a photo shoot :)

Another EF 100-400 f/4.5-5.6L IS II Mention

jdramirez said:
mrsfotografie said:
70-300L killer? I'll happily trade that in if the 100-400L II will fit in my travel bag!

Wishfull thinking...

I understood the 70-300 was optically better than the original 100-400... and didn't have as much of a dust issue... so I could see why one would sacrifice the 100mm reach... but if the mkii 100-400 is optically better than the 70-300L, I'm not sure what benefits the 70-300 has... maybe price... and technically a larger zoom ratio.

I think price is going to be a given sadly for my wallet. And I hate to mention this to some of the real gearheads but price is very important to how well a lens sells and shouldn't be written off. As for anything else it depends what you want to use it for. That 70-300 range is going to suit some sports shooters for example much better than 100-400 because it improves the amount of "near-side" (for want of a better term) action you can capture.

Canon 7D Mark 2 Rolling Review

Chosenbydestiny said:
Supposedly some say ISO 16,000 is usable on the 7D2, I've tried 70D and don't think it can go anywhere near that for usable files. I guess we'll see when more people actually have the 7D2 that use it for real world and rely less on reviews.

Welcome to the real world of Implied Performance.

I thought my car should go 200 MPH, the speedometer goes that far :)

Canon typically rates sensors for in-camera jpeg images with lots of NR. For most people, who print or view them on their smart phone, they look great.

Just like a D800, if you start viewing at 100%, you see noise and lost detail.

I had predicted that the sensor performance might reach ISO 1100 or even 1200 as rated by DXO. I was a little high, but its in that ballpark. That's actually pretty good for a APS-C sensor, and even ISO 1600 images can have lots of detail without too much noise. My old 7D could do ISO 800 before things broke up quickly. Part of the consideration is to see the slope of the noise curve. If its gradual, than pushing the ISO up will not degrade images as quickly. That's one thing I like about my 5D MK III, I can push the ISO way up without the image being totally hosed.

Sony patent discloses groundbreaking per pixel exposure sensor! - sonyalpharumor

jrista said:
Mt Spokane Photography said:
Patents for doing the per pixel exposure averaging have been around for many years. They refer to a patent from 2000, for example.


The novel thing about this patent is that it calculates blur due to the likely possibility of motion at the long exposure, and try to compensate for it. Sensors have progressed to the point where they can be better controlled at many FPS, so its a step towards actually being able to make something practical.

I'd still be skeptical about it being a practical thing to manufacturer, even if it can be done in a lab.


+1. Totally agree...not a new concept, many sensors out there today already do HDR in a single frame with either multiple exposures or other various tricks. This particular patent seems to trade spatial resolution for higher dynamic range.


Personally, I thought that Aptina's multi-bucket pixel concept was a better means of gathering more light than is normally possible for each and every pixel. Aptina's papers describe the use of multi-bucket to compensate for motion blur, but the additional charge buckets could also be used to flush charge from the pixel to subsequent buckets for longer, higher DR exposures, without the loss in spatial resolution.

I missed that one. I think that there are lots of possible ways to increase DR, usually they bring a downside with them. That does not mean that they are bad, but it may limit a product to being best for certain uses rather than trying to cover everything.

Lens Image Circle Diameter

You vary the exit angle of the lens assembly to make a larger image circle and can move the lens further away from the focal plane. However, Canon EF lenses all focus a exact distance from the flange of the lens to the sensor. You will see lenses inset varying amounts as part of the compromise of distance / exit angle. Look into the rear of your lenses, the distance to the glass often varies. And, on some designs, that rear element is part of a focus group, and it moves at the same time different elements are moving to compensate and adjust things like exit angle.

Optical lens design is the stuff of PHD's and many years of experience. There is no formula to design a lens, its trial and error. Obviously, you can start with a existing design and tweak it, but in the end, its still ray tracing. This used to be done on paper, tracing light rays as they travel thru a lens, then making a adjustment, and tracing again, maybe thousands of times.

Now computers do this, but since the variables are almost infinite, discovering a new optical formula that is better than existing ones, and does not cost a fortune to make is extremely difficult. That's why Canon and others patent a optical design or formula when they discover one that shows promise.


I'm not a optical designer, but have subcontracted lens design for my project to another company, and watched the process over the two years it took to complete. They did the ray tracing manually on paper, because it was a relatively simple lens. The Chief designer had a PHD, but had to consult with other experts frequently to get the job done. The final product managed to exceed requirements, which amazed everyone involved, since industry experts told us that what we wanted couldn't be done. It was also very expensive, there were many dozens of the lenses in each of our products.

Great Video on Polaris Off Road Course!

Whatever you do, don't watch this video! Be warned... if you do watch it, you'll likely be tempted to spend some serious cash on a new Polaris! Or on new video equipment and drones! Or both! (What I want to see is the 'making of' video on both how they built the course and how many runs they had to make repeatedly in order to practice/learn the course and then to get all the amazing shots on camera! There are some incredible pans and camera angles presented here! This video shows what being really good with a camera drone(s) can do!

USGP 2014!

Valvebounce said:
Hi V8.
More great shots.
Things like this always remind me of that line in Crocodile Dundee, "that's not a knife"

It was definitely a Crocodile Dundee moment ;D LOL. Actually, the bloke in one of the images (sitting next to the woman with the British flag) was flashing his big zoom, and his jaw hit the floor when this other guy sat in front of him with that monster lens.

Roo said:
I'm sure he got some great shots of the grid girls ;D

That's exactly what I would have used such a lens for. I like the way you think ;D

As for the parade cars, last year the car Jenson was in couldn't make it up Turn 1 and broke down. He had to hitch a ride with another driver ;D

Tripod

NancyP said:
Feisol CT3372 or 3472 (three or four sections, respectively), no-center-column "systematic" equivalent. You can get the center columns as accessories, as well as video bowls, etc. The 3472 is 4.5 pounds with retractable steel long spikes (4.0 pounds without the spikes), and the largest section diameter is 1.5 inches, maximum height without column is 68" (taller than I am, I never use it fully extended). It's bulky, with a very broad spider, but it will handle just about anything - it is a burly piece of kit. I would suggest this one for the larger Big Whites, rather than the smaller (2.1 pounds, leg diameter 1.1", 59" tall) and much more portable CT3342 or 3442. I have both the 3472 and 3442, the 3472 is used for telephoto work, the 3442 is used for landscapes and for macros.

+1 on Feisol. I've had the CT3372 for over a year and am very happy with it. It's used with a 600 F4 MKII routinely. Good value for dollar, reliable, quality.

2015 & 5DIV? Experts: what can be expected of a probable 5DIV in high iso IQ?

jrista said:
pedro said:
Thank you jrista for this detailled explanation! Will we ever come as close to such a great high ISO IQ as Sony demonstrates it, at the same or a similar price tag by Canon? I kinda doubt that, I guess they will ask another premium for that same thing... Sometimes I am pondering about purchasing a Sony A7s for the lowlight pics and keep with the 5D3 for the rest...


I don't know what to expect from Canon. A lot of people seem to be intrigued by small improvements here and there. The 7D II brings some big improvements to the AF system, which is wonderful...and I hope the iTR technology filters down to the rest of Canon's pro line (including the 6D). Beyond AF systems, though...Canon really likes to trickle out improvements, as slowly as possible, and at as high a cost as possible.


I certainly hope that come 2015, they will be releasing something fundamentally impressive with a layered sensor and low read noise, for a reasonable cost. What I expect is that Canon will release something that impresses a lot of people with a layered sensor, and high read noise. So long as Canon keeps using their off-die ADC units, I don't think we will see any improvement on the read noise front, and I think if Canon does that, it will diminish the benefits of having a layered sensor (i.e. they will have much of the same problems that Foveon has...which again boils down to high noise in the red channel and high read noise.)

I hope you are not holding your breath on that.

I would venture to guess, you might have taken a look at metabones and an A7 to complement your Canon lenses ....truth be told; I have as well, but there are painful compromises to be made.

Canon uses a Sony sensor in the GX7 but insists on using old tech in the Full frame sensors for now... If the last 2-3 higher end Canon body releases are any indicators, there will be definite improvements in high ISO performance, but DR is not something the Canon Geriatric board is considering as a priority (at least in their public statements).

I quote from the DPReview interview of Mr Maeda after the release of the 7Dii: Where he skirts the issue of DR in Canon sensors whether because he considers it un-important, or some other reason... I get the impression, DR is not something Canon top brass is looking to improve upon as a priority, they feel there are other components to a good image it seems...

'DPR: One thing we know from our own testing is that Canon DSLR sensors can’t quite compete with some modern sensors from Sony in terms of dynamic range. How important to you is developing sensor technology?

Mr Maeda: We are very focused on getting the best image quality. I’m not sure what measurements you’re looking at but when it comes to dynamic range for example we consider image quality as a whole, from low to high ISO sensitivities and on balance we consider our sensors to be the best.

My ideal camera is one that can take a picture in any environment from complete darkness to the brightest sunshine.'



Seems he is still concerned about hi-ISO performance ala 5dii, 1Dx, 5diii, 6d etc than other parameters like Base ISO noise, or DR in general. With those professed priorities (like overall IQ in general): I am not holding my breath on them delivering anything ground breaking in the DR area... While I enjoy using my 5diii, I would not mind getting a 5d IV or 1dxs when it ships, if it competes well with Sony sensors... I love my Canon lenses. I would love them even more if Canon stuck the 810 sensor in a 5D type body.
