Software & Accessories / Re: Camera bag for camping
« on: August 27, 2014, 06:18:04 PM »
you are much better off using a proper backpack and putting your camera gear in it. or strap a small camera back to your backpack. you will not have a good time trying to pack weight in a camera bag. i just put my lenses in their soft cases in the lid of my gregory pack, and hang my camera in a dry-sack (brooks bag) off a shoulder strap, or on a capture clip if its dry out.

you arent going to get a hiking backpack on as carryon

+1

Get a real pack... a true backpacking pack.... No camera gear pack will ever be half as comfortable. If you start hanging sleeping bags, tents, sleeping pads off of your camera backpack you are introducing yourself into a walking hell.... the stuff will be unbalanced and will sway with every step. You will tire yourself out fighting with your load.

Get a monopod that you can use as a hiking pole... you will appreciate it for balance and it saves the knees when going down steep grades / rockhopping.....

Look at lightweight camping gear and leave all the crap gadgets at home... An awful lot of what people carry is useless... you would not believe the kitchen gadgets I have seen abandoned on trails :) All you need for cooking is a small stove (I have an MSR Whisperlite), a small pot (1.5L titanium), a plastic cup, a spoon, a pair of chopsticks, and your swiss army knife... And dehydrate your food! Makes it lighter and easier to cook and burns less fuel... Get a lightweight tent/thermarest/down bag and 1 spare change of quick dry clothes and you are ready to go. If your pack weighs 10 kilos (before camera gear), you have too much stuff.

My favourite pack is still my Coastal Mountains backpack, still going strong after 25 years of use, a Lowepro holster bag for the camera/lens, and a betashell for the second lens.

Lenses / Re: Which lens to take on bike trip?
« on: August 27, 2014, 02:56:41 PM »
I will go on a bicycle trip through Florida starting on October 5th until December 18th. Since I will be very weight limited during this time I have to think about the gear I want to take along. So far it is:

7D without battery grip
15-85mm
40 pancake

Now the question is, if I should take another longer lens with me. This would either be the 70-200 4.0 non IS or the 100 L macro. They are about the same size and weight so it comes down to the subjects. From your standpoint, would opt for 100mm more on the long end or for macro capabilities.
I do not want to take both because of size and weight concerns. I really like to shoot macro pics but might miss some shots of birds and alligators if I don't take the tele.  :-\


Any tips for must see place are also welcome. I will start and end in Miami and plan to go to the Everglades first and after that to Key West.
what about the 70-200 and an extension tube?

Yes, I plan to get this camera. I hesitate to pre-order. I am most likely to give the business to my local camera shop, since I end up being honest and reporting big-ticket no-sales-tax items on my state income tax. (I don't bother with the small fry). I am expecting that the 7D2 will be a significant enough upgrade from the 60D to be worthwhile for a birding camera - increased frame rate, clearly better AF than the 7Dclassic (light-years better than the 60D and 6D for birding purposes), mildly improved sensor.
+1
but I will probably pre-order through my local camera shop......

Definitely an indication of pent-up demand..... I wonder how many will purchase one?

I thought the same thing, but when scrolling through all the pages, there are really only a handful of characters making the majority of all of this noise.  But I do think that the existence of hundreds of 7DII posts that have popped up here over the last year might be a good indication of pent up demand.

To answer your question:  I'll likely be an early adopter.
Same for me...
I was sorely tempted when to 70D came out... but sat on it in the hopes of an even better AF system on a successor to the 7D.... As long as they don't make it worse than the 70D (and that just isn't going to happen) I intend to get one too.... perhaps I should start up a poll :)

With all the hype on the forum about the 7D2, the question is asked.... "Are you going to get one"?

Who is serious about the camera and who is just kicking tires or wondering about Canon's possible plans for the future?

The CR guy is laughing all the way to the bank  ;)

The CR forum page on my monitor does not have any advertisement.  :P

Otherwise, yes, 48 pages of comments for the 7D2 rumor is quite something. Is this perhaps the most discussed rumor on CR forum ever? :) Shows many folks have high hopes on the new (rumored) sensor technology....

I believe that a lot of pros are more impressed with a camera that does the job with no surprises than the latest whiz-bang feature....

And if you look at Canon, an awful lot of new technology and features get introduced in Rebels and P/S cameras so the masses can "debug" them before it goes to pro or semi-pro level cameras.... and when they eventually make their way to the pro level cameras they are solid.

Yeah Canon may eventually add 4k. That just shows Canon is no longer an innovator, just a  follower.
Sometimes when you are following someone and they go off a cliff, it's a good thing that you had time to stop.....

Most buyers will be looking for integrated imaging devices, not specialized stills or video cameras.

Indeed.  That explains why everyone has one of these:



I cringe when I see those. It is a tool that does nothing well and usually leaves a mess behind....

and that means the split pixels it does not improve the file quality.

That's not what he was getting at. He's saying (I believe) they already have a finer process, and citing DPAF as proof, even though they currently are using it for something other than IQ.

Well, to be fair, he is still speculating about the 70D being made with a 180nm process. The 70D has only a few extra gates to handle the ability to read the two separate photodiodes in each pixel separately, as well as to bin them for a full pixel read. There isn't even a 10% increase in pixel FWC...if they had moved to 180nm, that means the border of wiring and transistors around each pixel would shrink by 320nm each side. That would lead to an increase in photodiode area of nearly 43%. Even assuming the independent read and binning logic takes up more space, I would still have expected more than a 9% increase in FWC if the 70D had moved to a 180nm process.
If they had done DPAF on the 500nM process, I would have expected the FWC to have dropped... yet, as you point out, it has slightly gone up...

of course, all this is speculation..... I have no inside information and am just guessing at a possible scenario....

Yes!
With the available space on the die, I believe that there is not enough space to build the circuitry required for DPAF for the 70D using the 500nM process...

Why is a cooperation like Canon not making a new sensor fabrication?

A new CMOS production line worth at least twenty million dollars. Without enough motivation, a old school cooperation is very unlikely to spend this kind of money on things like that. Therefore, the company decided to work the engineers' buds off to push the limit for the old 500nm sensor because it is cheaper.

The best reason that I can think of as to why they are not buying a new CMOS production line is because with the downturn in P/S camera sales, production capacity is opening up on their existing production line for small sensors, which is a finer line than that used for FF and APS-C (Non DPAF) sensors.

The second point to make is that the complexity of circuitry required to make a DPAF 70D sensor is beyond that which can be fabricated on the 500nM line... therefore, it must be fabricated on something else and that means the existing fabrication line for P/S sensors.... This means that they are now in the process of switching over to a finer line and when that is done, they can shut down the 500nM line and save money..... because it costs more to keep 2 lines running than 1 line.

Concerning heat dissipation, why not a Peltier unit affixed to the sensor assembly?

Extremely power hungry, you have to get the heat out somewhere (often a finned heat sink with a fan), very expensive.

For example:


http://www.atik-cameras.com/products/info/atik-4000

A peltier device adds heat to the system. It moves heat from one location to the other, and that takes energy. In a closed system, like a sealed camera, that's bad! You will just make things hotter. In most devices that use them there is either a big heat sink on the outside of the unit, or a fan to blow air across the peltier device to get rid of the excess heat... I suppose you could use the bottom of the camera as the heat sink and then use a metal tripod to help conduct it away, but most of the time that isn't an option.... and as mentioned above, you would drain the battery very fast.
