The 5D3 was designed as an all-round camera.....
The 7D2 was designed to fit a niche......

What do you think?

Third Party Manufacturers / Re: Co-worker dumps $5k on Nikon

People here talk about not knowing anyone that buys Nikon and how Nikon is always making a loss and how Nikon cameras don't rate as well as Canon on Amazon, etc ...

Co-worker is planning their holiday and wanted the best camera to take on holiday and went with a D810 plus lenses.

My input into the buying decision? Didn't know that she was shopping until she mentioned what she'd bought.

Do they shoot sports? No
Do they shoot birds? No
What photographs will he take? Typical tourist pics.

When asked why she wanted the Nikon D810 her answer was simple: "I just want the best IQ."

No, I'm not making it up.

(Reposted because someone decided to be pedantic, so I've corrected for their pedantry.)

So what..... given the constraints, it sounds like they made a good choice.

Carbon fibre is very delicate.... NOT!!!!!
Carbon fibre is brittle in the cold.... NOT!!!!!

We launch communications satellites with carbon fibre dishes.... Space gets very cold and very hot, yet somehow they survive.

People ride the tour de France on carbon fibre bicycles.... yet somehow they survive.....

I have a carbon fibre canoe paddle that has survived four years of hard use....far more stress than ANY tripod is going to see, yet somehow it has survived.....

Apologies for the picture... I had to take it with an iPad because there are black and there are light elements in the photo.... I could not use my canon because it doesn't have enough DR.

Yes exactly! that's one of the options I am considering as those small backpacks can flatten itself. It could also be used for other stuff once in a while. The thing is that it would be harder and longer to get the gear inside and the tripod wouldn't fit.
Have you ever tried using those bags for photography equipment?
Not since this morning :)

if ML was fully endorsed by Canon, a much higher percentage of Canon owners would probably install it on their Canon cameras.

I for one would never put unsupported third-party firmware on any electronic device. Especially not, when I am told by the manufacturer that it voids warranty on the product. And I also do not open iPhones oder disassemble Canon cameras physically. I am not Roger Cicala .. I would not get it back together and working again.   ;D

And I guess the majority of Canon users handles it the same way.

Personally, I laugh at "no serviceable parts inside" stickers.... and yes, I have opened cameras and iPhones and replaced parts.... but then, that's part of what I do for a living and there are microscopes and surface mount soldering stations in the lab :)

Since you mentioned MEC backpacks...

They have a couple of small daypacks that don't have any stays and are quite light that you can stuff into your real pack... That way, when travelling with everything, all fits into the main pack. when just bringing the camera gear, take out the daypack, load in the desired gear, and away you go..... and don't forget an ultralite drybag in case of rain....

This is the guy who made a video to claim that Panasonic and Olympus "cheat you" by labeling their f/2.8 lenses as f/2.8 lenses.

The Panasonic FZ200 has f/2.8 24-600mm printed on the side of the barrel, that's a lie.
If the last lens element isn't 215mm across, it isn't 600F2.8......

I think going to a dual system is very restricting :)

Mostly, I shoot Canon... but for the Kayak there is nothing in Canon land that comes close to the ruggedness of the Olympus "Tough" series of p/s cameras. Despite the improved weather sealing of the 7D2, it does not have underwater modes :) ... and for use on a kite or a drone, it is very hard to beat a GoPro.

To my way of thinking, it is the task that dictates the equipment choices, not brand loyalty.

I disagree with this, just based on my practical experience with both the 7D and 5D III.  ...

There are still issues with dark current. Hot pixels still exist in modern cameras. I cannot speak for the 7D II,

First, this is supposed to be a thread about the 7D Mark II and what a game changer it is.  You are talking about problems with older cameras.  On page 7 you posted an image of the Orion nebula made with a 5DIII, 600 f/4, an hour of exposure, and many flats, darks, bias.  You got a little of the faint nebula dust around M42.  Nice image.  BUT..

I am attaching an image made with the 7D2, 300 f/2.8, no flats, no darks, no bias, and only 27.5 minutes of exposure (plus a few short exposures down to 2seconds for the core of M42).  That is 27 61 second exposures at ISO 1600.  Simple tracking with an Astrotrac, and no guiding.  Simple processing: raw conversion in photoshop with lens profile, and photoshop reads the hot/dead/stuck pixel list and does not include them in the raw conversion.  Then simple align the images, and sigma clip average.  Then stretch with curves in photoshop.    There are NO issues with hot/stuck/dead pixels in the final image.  There is no problem with amp glow or non uniformity of the background.  The pink glow in the lower left is the emission from IC 342 where the Horsehead nebula is.

Your aperture is 150mm diameter/ mine at 107 mm diameter,  square the ratio, so you collected twice the light  per second from the subject and more than twice the exposure time, so 4 times the light.  Yet I show much fainter nebulae using much simpler methods.  THAT is why the 7D2 is a game changer. 

Again, please see my description of simplified methods for night photography here:
Flats, darks, and bias frames are no longer needed.

I find both of your pictures inspiring... but I must say that I am very impressed with the results Roger gets from a far simpler method... If I ever get a clear night here I have to go try this out!

Yes, it could happen..... but it is very unlikely. Buy a camera for what it can do, not what you hope it someday might be able to do.
I fully agree that one should buy a camera for what it will do for you today. That is why I said the criticism for lack of 4K video is justified given the market situation. I might be mistaken but I don't think video functions have ever been added with firmware updates.

Anyway, I am interested in knowing if there is an actual hardware limitation preventing 4K on the 7D-II or is it something that perhaps the ML team might be able to overcome. Is 4K video with DPAF a completely unrealistic prospect given the technology at hand? ???

If you look at, what the guys from Magic Lantern have done with Canon firmware, then it's reasonable to say that Canon is holding back basic video features(peaking, zebras etc).

As for 4k it gets a lot more tricky. The main problem is the writespeed and the encoding. I think that I saw somewhere that the 7d MkII can archive speeds around 100mbs, which is a not very much, when you are talking 4k.
I think the day Canon announces 4K video in the DSLR lineup is the day they will also announce that the new camera is using cFast cards to store it on...It's one thing to be able to process a 4K stream, but if you can't put it anywhere, what's the use of it?

That said, the latest GoPro has 4K at 30fps... but it is heavily compressed.

I am going to need a tracking mount. Any recommendations? Not top of the line stuff, already spent way over budget on equipment this year. In fact the cheapest product that is proficient enough.

Yeah I agree.  It depends on the weight of the rig, does it need to fit in a backpack or something you will use from home only or can transport in a car?  Are you going to shoot deep space objects or wide star fields?

Cheap solutions can give you hours of frustration and not deliver what you expect.

This is about the minimum you can get away with.....

Why do so many people including reviewers seem to pretend the 70D doesn't exist or is really really new by always comparing it against the 7D just to make it look that much newer and better?

(for the record I really like my 70D - it's just this almost goggles view to compare it with the 5yr old model instead and then say it's new ...)

Because it's even stupider when you say that the 7D2 is 2 percent better and try to justify that 2% as a ground breaking innovative game changing paradigm shift that completely changes photography as we know it.

I have shot for many years with a 60D... identical IQ to the 7D... A friend got the 70D and you could barely tell any difference. I have a 7D2 and it is hard to see any difference over the 60D until you go to high ISO. The AF system is an order of magnitude better, but you have to pixel peek and still won't see any significant difference in IQ for normal use.

As digital cameras mature, you will see less and less difference in IQ between revisions... everyone is approaching a wall.

Canon is losing quite a few landscape photographers these days, because there is stiff competition to fill all the broad and niche landscape needs. I still use Canon for landscapes because I like their system and I have no complaints with my process. I can still see vast majorities of people wanting to get into landscapes who are not even considering Canon because of lower MP and less DR. I personally stitch and bracket all of my shots (never missed a shot), so I have not much to gain by leaving Canon, but others certainly see the need.

Respectfully disagree, Johan.  Canon isn't really losing folks to mirrorless nearly as much as they are losing folks to Sony sensors -- people are 'switching to mirrorless' just to get their hands on what they think will get them better IQ.

Consider:  one of the Sony a7 bodies with an adaptor is probably the cheapest way to get a "better" sensor for FF work without having to flip all your glass.  Landscapers are the ones willing to give this a try first, as they need AF far less than most photographers and LV can get them by.

But we continue to hear of everyone leaving Canon for a host of reasons, principally due to the sensors, and secondarily due to their avoiding any significant commitment to mirrorless.

Canon will eventually commit large dollars to mirrorless and make a proper go of it -- with APS-C, not FF.  (I don't see a 4th mount happening.  But they'll pony up an EVF, offer DPAF, and (please) offer a greater variety of small, native EF-M lenses and people will buy it.

The big wild card is when.  I've heard a thousand forum-dwelling photography enthusiasts that claim that Canon is falling so far behind and that everyone is leaving them, but I haven't seen a speck of sales data that shows that Sony / Fuji / etc. are converting large numbers of DSLR users from them.  If that starts to happen, Canon will deploy more competitive products in that segment.

- A
But it's true.....

Everyone has left canon..... Yet somehow they are still number one in sales.....

Nobody likes the 7d2, yet it is a hot seller.....
Perhaps Internet wisdom is flawed.....
