best quallity ,full framecanon dslr choice ?

[Macadameane]

People aren't constantly developing software for DIGIC processors. Desktop computers are pushed to be faster because people are constantly developing applications to push limits.

Can a camera processor be faster yearly? Sure it can. Does it need to be? No. I love my 8 fps on my 7D, but there is more than processor speed that I care about. If canon is trying to release pro cameras constantly, it will hurt them. How many people on this forum alone are still carrying a 5D classic, a 40D, or even an older Rebel. They still get the job done! Desktop computers don't always have this luxury. As technologies improve, if you want newer software, you must upgrade. Whereas with a camera, you can still take great photos even with an "outdated" camera.

So while we wouldn't expect the 5dmkiii to double it's frame rate from a mechanical point of view - necessarily, it could very easily process the data from the sensor twice as fast!

That seems consistent. The 5DII processes data twice as fast as the original 5D, and while the frame rate only went up by 0.9 fps, the 5DII sensor produces 60% more image data per frame.

it isn't a stretch to ask for a full frame camera to do 8fps with current technology.

I should think not, since Nikon's D3s offers 9 fps from a FF sensor (albeit one with only 12 megapixels).

But knowing a DSLR is essentially a computer why do we have such outrageous prices for used models? A used 5dmkii (or any used camera for that matter) selling for almost what a new one sells for is a crime imo. As someone above me said, you wouldn't buy a 2008 model computer for todays prices.

True - but that 2008 model computer might have some trouble running the current OS and software, whereas a 2008 dSLR can still take good pictures.

"True - but that 2008 model computer might have some trouble running the current OS and software, whereas a 2008 dSLR can still take good pictures."

I build my home computers and the last time I threw one together was 2009. I bought a very good processor and top of the line video card and RAM. It runs like a raped aped still today and there isn't any software on the market it can't handle flawlessly, but I couldn't sell it today nearly what I paid for it.

I don't point that out to rebut your statement so much as I do to bolster my position that 'old' cameras fetching a premium are overpriced - but for perhaps a good reason. I think it is precisely because Canon (and Nikon) do not come out with new models every few months that keeps the prices of their older products high.

Could they produce a camera every 6 months with 1/4 more processing speed and thus larger sensors with faster shutters? Yes, I believe they can. Can the market support it? No I don't think so. Camera buyers are far fewer in number than home computer buyers (some homes have 2-3 computers) so it wouldn't make sense for them to introduce a bunch of new upgrades so often.

So they wait 2-3 years and introduce an upgrade that is not up to the potential of the processors abilities according to Moore's law. For instance the next 5dmkiii could realistically have a 30mp sensor (conservatively, according to Moore's law) and a 10fps shutter mechanism but will it? I doubt it. I guess that's my main point: they could double their sensors abilities every 2 years but instead we have incremental improvements across a series of levels of camera bodies and be charged a premuim for the increase.

I'm not trying to be argumentative; nor am I trying to say I hate Canon and their products. To the contrary. I Just don't think we are getting the true potential of the DSLR product.

i just bought canon 5d mark ll today $2499 and it"s brand new,
when i check the battery info i saw shutter count: 400
shouldn"t be 0 or is not bigh deal?
is it possible after shooting alot , bring the shutter count to the minimum? (with new firmware)?
thanks for any response.

If you're seeing that under Battery Info, that just indicates the shutter count for that charge on the battery. It returns to zero when you charge the battery. I'm not sure why it didn't start at zero - sounds odd (and $2499 is a bargain today) - did you buy from a reputable dealer?

The actual shutter count (as recorded by the camera and read out using software like EOSInfo) cannot be reset (or if it can, I have no idea how, but the idea is that it's like the odometer on your car...).

I Just don't think we are getting the true potential of the DSLR product.

Medium frame cameras take photos with 16 bits of tonal range (just 2 bits more than FF and APSC cameras), at a rate of barely more than 1 per second, and sell at tens of times more than FF and APSC cameras. So, the true potential of a camera, could be to take better photos, not faster and with more pixels.

Could they produce a camera every 6 months with 1/4 more processing speed and thus larger sensors with faster shutters?

Ah, you believe that sensors are small because the microprocessors are slow. You really have to stop thinking at cameras like they are computers and microprocessors, and see that they are optical devices (limited by advances in optical and mechanical engineering) designed to count photons (that have certain spectra).

http://en.wikipedia.org/wiki/Full-frame_digital_SLR

Production costs for a full-frame sensor can exceed twenty times the costs for an APS-C sensor. Only 20 full-frame sensors will fit on an 8-inch (200 mm) silicon wafer, and yield is comparatively low because the sensor's large area makes it very vulnerable to contaminants—20 evenly distributed defects could theoretically ruin an entire wafer. Additionally, the full-frame sensor requires three separate exposures during the photolithography stage, tripling the number of masks and exposure processes.

Camera development depends on how photosite technology scales to a smaller size and a smaller readout time per bit of tonal range, and also depends on other electronics (not the microprocessor) and mechanical advances (like the shutter and autofocusing mechanism).

i bought it from west camera .after buy 5d mark ll, when i came back to home, the new battery wasn"t charge full(like other new camera) and i just charge a littele bet, ho do i see the shutter count in 5d mark ll?

The batteries do not come pre-charged. In fact, it would be bad if they did, as storing a Li-ion battery with a full charge for a long period of time (such as on a store shelf) is bad for the battery. But I would think the bettery would still not show a shutter count when you inserted it. It's possible that event though you bought it 'new', it was opened and used in the store.

You can use EOSInfo to see the shutter count.

The 5D MK II comes with a battery, did West Camera sell it separately? If it was sold separately, something sounds wrong.

The camera is able to read the serial number of the battery, and to record the number of shutter actuations between battery recharges. This is how it determines the health of a particular battery.

A battery shutter count as noted would only tell you how many shutter operations that battery has.

To use the EOS info tool, you must first install the canon software because it uses the drivers from Canon. You cannot get the information from the camera without using this or similar software.

Also be aware, if you put a memory card in a new camera without first formatting it outside the camera, it will start numbering images with whatever number was last used with the card, or, if the internal camera image number is larger, it will use that. Sometimes buyers use a card from their current camera, and see the first image from their new camera has a high number.

no, west camera didn"t sale separte battery and 5d mark ll, they sold me on the box everything together, i google searched for where will be showing shutter count in 5d mark ll, but i found thise camera and another dslr brand (1d old model) doesn"t show the shutter count.
i don"t know this is the right answer or something els

The 5D MK II will NOT show the shutter count, none of them do. However, it is recorded internally, and a software program is available free to read the shutter count. Neuro provided a link to it, it is called EOS INFO and it reads information like shutter count not otherwise available. Unforyunately, newer cameras have locked it out, but it works with the 5D MK II just fine.

Remember to install the Canon software first.

"Computers aren't the same as cameras. Comparing them is like apples and oranges."

1. I have to disagree with that statement. Essentially a digital camera IS a computer.

2. So why wouldn't it be logical to expect a camera's abilities to increase substantially every couple years? Note, I didn't say double every two years, but a substantial increase.

3. But knowing a DSLR is essentially a computer why do we have such outrageous prices for used models?

1. A digital camera *has* a computer inside, but it is not a multi-function device, like a 'desktop computer.' It's more comparable to a 'gaming' system (PS, XBox, etc.): a single-function device, which use proprietary hardware and, like cameras, get updated much less frequently.

2. Because computers are general function devices that use standardized hardware and there is a lot of competition. Another reason is that the system vendors (HP, Dell, IBM, etc.) don't have to design and build their own processors: Intel and AMD take care of that, and their head-to-head competition drives design and keeps prices down. Canon and Nikon know that you're not going to take your lenses and mount them on some start-up company's camera, so they don't have to release new cameras as often. Since they're both making lots of money, they have no reason to change. [If all lenses fit on all cameras without an adapter, and all of a sudden a new company came along and started rolling out new cameras on a faster schedule with new features, Canon and Nikon would be forced to change.]

3. Supply and demand. People can sell products (new or used) for whatever the market will bear. If no one was willing to spend that much money for a used camera or lens, the prices would be lower. It also shows the lack of homework that people do, especially when you see someone buy used equipment on places like ebay for close to or even more than a new item.
