Since Nikon came up with AF-S, VR, D300, and D3, Canon's technology advantages are diminishing. Nikon still have an edge in flash photography. Will Canon come up with something else? Who knows? But we'll see more people talk about leaving to Nikon.

 

As long as neither one has obvious advantage over the other, competitions help the price low, quality high. It benefits consumers.

They are about the same price. How do you compare these 2 softwares? What are

the advantages and disadvantages of each one?

Nikon doesn't have the facility to manufactur FX sensors, not even DX sensors. Nikon probably design the chip and have some fabs manufactur for them.

Canon 30D is 1 year younger than Nikon D200. 30D tends to have better/improved technology.

 

Canon 30D has 8MP, while Nikon D200 has 10MP. 30D tends to have less noise. Square of the 25% density difference is 62.5% noise advantage.

 

Plus many other reasons. Switching between system simply based on 30D and 200D noise isn't quite reasonable.

First, please drop our emotion on our investment and don't trash Nikon or

Canon. They should work hard and compete hard for us because we are supporting

them financially. Don't be a slave to either company and to pay them.

 

Could you list the advantages and disadvantages of each flash system?

Ellis, don't be a smart ass.

 

Peter is looking for something as clean as D3. D300 is not the level yet. You know nothing about D3 and D300. Nikon is not going to make D300 perform the same as D3, noise-wise.

DX sensor is 23.7mm x 15.6mm or 369.72sq-mm

FX sensor is 36mm x 24mm or 864sq-mm

12MP FX has the same density as 5.1MP DX sensor

 

If Nikon D40 uses the same workmanship as D3, we will have a very low noise 6MP DX camera at the price of $2,500, half the price of D3. Since you don't buy it, Nikon drops the idea and makes a cheap D40.

I always thought that 50% crop is like a zoom-out while 200% crop is like a zoom-in. I guess I need to drink more beer.

Do you think "Ken Papai - Marin County, Calif" is correct? I doubt it.

"Canon Pro Services' single requirement: at least 51% of one's income must be derived from photography."

 

I have been a Canon Pro in the summer before I went to college. I used my father's Canon P&S to take a picture of a girl. My buddy gave me $1 for that picture. That is the only income I had in that summer.

10D is 6MP and is a 2003 product. 40D is 10MP and is a 2007 product. All manufacturers have huge improvement on high ISO noise control. I suspect that the ISO setting is only a upper limit of sensor signal amplification you assign. In bright environment, cameras don't need to pump up the signal so that the noise is avoid. In older design, I guess the circuitry pumps up the signal regardlessly and increases the shutter speed, decreases the aperture, ... Plus sensor signals are digitized earlier to avoid signal noise generation during signal propagation, I guess.

 

Yes, newer cameras are way better in noise control. Nikon claims its D3 can achieve 256,000 ISO with very little noise. Many photos prove that claim.

Cont'd

 

I don't know how ISO circuitry works inside a digital camera. If it is like an amplifier where its amplification depends on the volume control, then the noise depends on how much volume control we need. The lower the volume, the less noise.

 

In a bright suuny day, even in high ISO settings, internal circuitry (volume control) is only lightly turned on. That is why there is no noise (grain). In low light environment, internal circuitry push the signal from the sensor higher and create noise.

 

For low ISO settings, internal circuitry gain is limited. That is why there is almost no noise (grain) even in under-exposed cases.

 

These are just my guess. Correct me if I am wrong.

Cont'd.

 

That was why I post question if all new cameras can handle high ISO grain or the camera automatically force a lower ISO (not likely) or I should call the police that I lost the grains I had before.

I mistakenly kept ISO-1600 setting from previous shootings and was using 18-135 f/4-5.6 zoom plus SB-800. Then I took ouple of bright indoor with flash on and apexture priority at maximum.

 

The pictures came out very good, no difference from low ISO settings. That made me wonder where the grains went to?

I mistakenly set my D40X camera to ISO 1600 under a bright environment. Will

the photo come out more grainy than ISO 100 or ISO 200?

 

Under a bright sunny day, will ISO 100 photo come out better than ISO 200?

Harry, you really try to start a war. Most people on this EOS board are pro-Canon, although may not anti-Nikon.

 

First, I believe you were in Auto mode all the time. You didn't switch to manual mode. Second, Nikon lost a lot of professionals in sport photography because of their slow AF system, while Canon has USM AF system. Nikon new AF-S is as fast as USM. I guess your lens is an old stock.

Dawn, Nikon "compatible" flash is very cost effective but may not work all the time. I learn my lesson well.

What is the difference?

A 100mm lens in 35mm format will be 150mm in Nikon APS-C format, with the same

aperture. What about the DOF? Does it also has 1.5X factor?

I thought KEH is a reliable used gear dealer. Thanks for the info.

It seems that the next high-end Canon is a full-frame 21MP. The next high-end

Nikon is a full-time 12MP with amazing clean high ISO image. And Nikon's

flagship APS-C camera remains 12MP with very very little high ISO noise.

 

From a Canon user point of view, which approach is more practical or more

useable?

PuppyFace, "at 12.8MP my 5D is already taken my L optics to the limits of their resolution"

 

Depends on you f-number. When you are using f/1.2 or f/1.4, EF-L lenses should work fine with EOS-1Ds Mark III, which is 21MP. But if you are using f/32 or f/64 etc, your photo is limited by the glass not the MP of the sensor.

The D40/D40x series are real GEMS. D40X even beat Fuji's S3-Pro in dynamic range, as someone told me some time ago. I am sure Nikon has some advanced technology applies to its new products: D3 and D300.

And what do you mean: DR is the same at low ISO and at High ISO?

What is DR?
