The price is right for 1D2s now however, if you can get a good one. Absent the little problem that for the money, today it is a POS. You're free to have that opinion. I won't trade it for a Nikon half frame. Larger sensors are better than smaller... That holds true for two sensors of the same technology generation. It doesn't even come close to valid for any sensor from 2004 compared to what Nikon uses today. The D7100 runs circles around anything that existed in 2004. Here is a chart, automatically generated from data collected by Bill Claff: http://home.comcast.net/~NikonD70/Ch...%20Mark%20II,D 710 0,D 4 The bottom line on the chart is your 1DII. The middle line is a Nikon D7100. The top line is a Nikon D4. The difference between a D7100 and a D4 is exactly that "larger sensors are better than smaller". Same basic technology. To get the most from that chart, click on "Ideal_FX" and on "Ideal_DX" to see exactly what the difference between a cropped sensor and a full frame sensor is, absent the technology generation gap. The D7100 is closer to "perfect" than the D4, though not by much. The 1DII is a long long ways... The 1DII is old, and "POS" describes well how 10 year old sensor technology compares to the current technology. Stick with a Canon camera if you have many lenses, but don't kid yourself about the image quality your Canon can't produce. And while we've been talking about comparing to a Nikon, if it is compared to a Pentax or Sony the results are very similar. As said: You're free to have that opinion. I stand by mine. I like Canon files better and a larger sensor give the lenses more real estate to resolve on. Opinions are wonderful, but they do have to be based on facts, and yours are not. You might well like the Canon files better, but not because they contain higher quality images. They don't. A larger sensor can provide better resolution, but in this case it does not. The Canon 1DII has a sensor that is 28.7mm wide. It produces images that are 3,504 pixels across. That is 3504 / 28.7 / 2 line pairs per millimeter, which is the maximum resolution of that senosr: *61.0 lp/mm*. The Nikon D7100 has just about the highest resolution of any camera, regardless of sensor size, currently available. It has a 23.5mm wide sensor that produces images 6000 pixels across. 6000 / 23.5 / 2 = *127.7* *lp/mm*, or just a little more than two times the resolution of the Canon 1DII. Just in case you wonder, the D800 and D810 are only about 102.5 lp/mm, the Nikon D4 is 68.5 lp/mm. The D3300 and D5300 are the same as the D7100. Literally every entry level cropped sensor camera that Nikon currently sells has better resolution (less noise, and higher dynamic range too) than you old 1DII. Sheesh, even Canon's current cameras are better than that one! You just don't wanna get it! The larger the sensor the more of the lens area of confusion can get utilized and thus it contribute more information that can extracted from the final files. That said: The M is an excellent data-back to the fisheye that I use since I want to have a rectangular image. And that image gets 18 MP. What is "the lens area of confusion"??? If you are referencing the Circle of Confusion, you are wrong. But I was... And I think that you might be a part of it! Look up "Airy Disk" and see how that relates to pixel pitch. Same thing. The "CoC" just is determined by a threshold instead of a curve. Pixel pitch and lp/mm are directly related... How could they not. But "The larger the sensor the more of the lens area of confusion can get utilized and thus it contribute more information that can extracted from the final files." The 1DII has no advantages, other than the fact that you already own it. Oddly though, you could sell it and buy a vastly better camera and have money left over! The 1D2 just came into the discussion as a little something to compare the D7200, and maybe the D7300 to... The 1D2s don't fetch much on the markets these days. Lots of wandering discussion, but none of it is accepting the simple fact that the D7100 has a sensor that resolves far more detail than that old 1DII can. And with better dynamic range too. You don't seem to have realized that it isn't sensor size, it's pixel pitch that counts. -- Floyd L. Davidson http://www.apaflo.com/ Ukpeagvik (Barrow, Alaska) |

For a given specific lp/mm value, say the 102.5 lp/mm of the D800, the resolution will not be different if the sensor is smaller or larger. What that would change is the total number of pixels that can be on the sensor. A smaller sensor with a larger lp/mm value, if all other things are equal (same technology for the sensors) will have greater resolving power. However, since the physical diameter of each sensor well is necessarily smaller to get the higher pixel pitch, the dynamic range will be lower. An interesting example of how that knowledge can be used is to compare the size and pixel pitch of the D7100 to the D810, and from that predict what the next full frame sensor from Nikon to replace the D810 will be. (This doesn't apply to a D5 replacing the D4S, because that is targeting a smaller pixel count to maintain a higher frame rate.) The current 128 lp/mm on a D7100 size sensor, if manufactured at full frame size, would be a 60MP sensor. I would expect that relatively soon after the D5 is announced Nikon will announce a body with at least 60 MP to replace the D810. -- Floyd L.

The Canon 1D2 also produces 18 raw in buffer but @ 8 fps. The 1D2 was introduced in 2004... Keep them coming Nikon! Humor at it's worst! The Canon 1DII also cost $6000 when it came out, and was the top of Canon's pro line of DSLR's. It had 8MP and would shoot at 8 fps, with an ISO range of 100-1600. Nikon of course introduced the D2X in the same year, at a cost of only $5000. With 12 MP and also at 8 fps. But while it had more pixels the ISO range was only 100-800. The memory buffer would hold 17 of those larger RAW files, compared to the Canon 1DII holding 20 smaller files. Looks like Canon maybe was barely ahead of Nikon in 2004. In 2015 Canon hasn't moved much in a decade, and Nikon took off like a rocket! The latest Canon crop frame camera, the 7DII ranks overall at number 108 on the DXOMARK list. The current entry level bottom end from Nikon, a D3300, ranks 32! And the top Nikon APC-S, the D7100 is at 23, so we can expect the D7200 to almost certainly be at or very near the top 20 will Canon can't make the top 100. Because no doubt Nikon, unlike Canon, has indeed been able to "keep them coming". Well... My 1D2 wont be replaced by some Nikon halfframe! ;-) I read DxO too, but not the ranking but graphs and numbers... Everyone has different needs for a camera. Not everyone has need for the best camera. You'll do fine with your 1D2, and Grandma's family album won't be any worse because of it. The EOS M is what I have in me bag... The price is right for 1D2s now however, if you can get a good one. Absent the little problem that for the money, today it is a POS. You're free to have that opinion. I won't trade it for a Nikon half frame. Larger sensors are better than smaller... That holds true for two sensors of the same technology generation. It doesn't even come close to valid for any sensor from 2004 compared to what Nikon uses today. The D7100 runs circles around anything that existed in 2004. Here is a chart, automatically generated from data collected by Bill Claff: http://home.comcast.net/~NikonD70/Ch...S%201D%20Mark% 20I I,D 710 0,D 4 The bottom line on the chart is your 1DII. The middle line is a Nikon D7100. The top line is a Nikon D4. The difference between a D7100 and a D4 is exactly that "larger sensors are better than smaller". Same basic technology. To get the most from that chart, click on "Ideal_FX" and on "Ideal_DX" to see exactly what the difference between a cropped sensor and a full frame sensor is, absent the technology generation gap. The D7100 is closer to "perfect" than the D4, though not by much. The 1DII is a long long ways... The 1DII is old, and "POS" describes well how 10 year old sensor technology compares to the current technology. Stick with a Canon camera if you have many lenses, but don't kid yourself about the image quality your Canon can't produce. And while we've been talking about comparing to a Nikon, if it is compared to a Pentax or Sony the results are very similar. As said: You're free to have that opinion. I stand by mine. I like Canon files better and a larger sensor give the lenses more real estate to resolve on. Opinions are wonderful, but they do have to be based on facts, and yours are not. You might well like the Canon files better, but not because they contain higher quality images. They don't. A larger sensor can provide better resolution, but in this case it does not. The Canon 1DII has a sensor that is 28.7mm wide. It produces images that are 3,504 pixels across. That is 3504 / 28.7 / 2 line pairs per millimeter, which is the maximum resolution of that senosr: *61.0 lp/mm*. The Nikon D7100 has just about the highest resolution of any camera, regardless of sensor size, currently available. It has a 23.5mm wide sensor that produces images 6000 pixels across. 6000 / 23.5 / 2 = *127.7* *lp/mm*, or just a little more than two times the resolution of the Canon 1DII. Just in case you wonder, the D800 and D810 are only about 102.5 lp/mm, the Nikon D4 is 68.5 lp/mm. The D3300 and D5300 are the same as the D7100. Literally every entry level cropped sensor camera that Nikon currently sells has better resolution (less noise, and higher dynamic range too) than you old 1DII. Sheesh, even Canon's current cameras are better than that one! You just don't wanna get it! The larger the sensor the more of the lens area of confusion can get utilized and thus it contribute more information that can extracted from the final files. That said: The M is an excellent data-back to the fisheye that I use since I want to have a rectangular image. And that image gets 18 MP. What is "the lens area of confusion"??? If you are referencing the Circle of Confusion, you are wrong. But I was... And I think that you might be a part of it! Look up "Airy Disk" and see how that relates to pixel pitch. Same thing. The "CoC" just is determined by a threshold instead of a curve. Pixel pitch and lp/mm are directly related... How could they not. But "The larger the sensor the more of the lens area of confusion can get utilized and thus it contribute more information that can extracted from the final files." The 1DII has no advantages, other than the fact that you already own it. Oddly though, you could sell it and buy a vastly better camera and have money left over! The 1D2 just came into the discussion as a little something to compare the D7200, and maybe the D7300 to... The 1D2s don't fetch much on the markets these days. Lots of wandering discussion, but none of it is accepting the simple fact that the D7100 has a sensor that resolves far more detail than that old 1DII can. And with better dynamic range too. You don't seem to have realized that it isn't sensor size, it's pixel pitch that counts. I think that I have given you an answer to that... Lot's of snow? You have demonstrated that you don't know the significance the terms you are using. Buzz words... Again, resolution is measured in lp/mm. A higher number is better resolution. The actual total size of the sensor is not significant. The pixel pitch is the measurement that relates to the size of the Airy Disk. For a given specific lp/mm value, say the 102.5 lp/mm of the D800, the resolution will not be different if the sensor is smaller or larger. What that would change is the total number of pixels that can be on the sensor. A smaller sensor with a larger lp/mm value, if all other things are equal (same technology for the sensors) will have greater resolving power. However, since the physical diameter of each sensor well is necessarily smaller to get the higher pixel pitch, the dynamic range will be lower. Smaller pixels makes more noise... Big news! An interesting example of how that knowledge can be used is to compare the size and pixel pitch of the D7100 to the D810, and from that predict what the next full frame sensor from Nikon to replace the D810 will be. (This doesn't apply to a D5 replacing the D4S, because that is targeting a smaller pixel count to maintain a higher frame rate.) The current 128 lp/mm on a D7100 size sensor, if manufactured at full frame size, would be a 60MP sensor. I would expect that relatively soon after the D5 is announced Nikon will announce a body with at least 60 MP to replace the D810. The size does matter. I'm not talking about what's resolved per mm or inch but how much information a license can resolve to file. Not the same thing. So now you want to change the subject and talk about something else? That is what this entire exchange has been about since you decided to talk about it with nonsense. How much information is resolved is measured by in lp/mm. What "license" do you mean? Apparently lot's and lot's of snow! Another odd subject that you probably know nothing at all about. -- Floyd L. Davidson http://www.apaflo.com/ Ukpeagvik (Barrow, Alaska) |

Not license but lense! Lenses do not resolve information to a file. Regardless of that, the measure of lens resolving power is line pairs per unit of length, or lp/mm for example. http://dictionary.reference.com/browse/resolving+power Or today "Modulation Transfer Function" is often used, but that is just a conversion to a different way to describe the same thing, which is spatial frequency response. Here's another good reference, http://www.normankoren.com/Tutorials/MTF.html Look down the page a ways for this statement: MTF is the spatial frequency response of an imaging system or a component; it is the contrast at a given spatial frequency relative to low frequencies. Spatial frequency is typically measured in cycles or line pairs per millimeter (lp/mm), which is analogous to cycles per second (Hertz) in audio systems. Lp/mm is most appropriate for film cameras, where formats are relatively fixed (i.e., 35mm full frame = 24x36mm), but cycles/pixel (c/p) or line widths per picture height (LW/PH) may be more appropriate for digital cameras, which have a wide variety of sensor sizes.
