When Nikon releases their 16MP D95 and Canon releases the 18MP 60D, would it be possible to stop all the insanity over megapixels?
Getting real tired of the debate.
Alternatively, maybe we could create a special Megapixel War thread and let the two sides fight to the death.
I shot film for most of my life. If you used Tri-X you got some grain. If you pushed it to 1600 you got more grain. If it bothered you, you went to a larger format. It seems like people want to push their digital cameras to 6400 and think they shouldn't get noise. I'm just so incredibly amazed at the quality of the shots that come out of my 7D that I can't figure out what the issues are.
My issues on the 18MP APS-C camera are: 1. The sensor has out resolved the bset of the prime lens. 2.Diffraction limited at f6.7. 3.Noise at higher ISO (400 nad UP)is even worst than 40D. 4.Built in noise reduction further reduced the sharpness og the picture. 5. Dynamic range is 1 stop less than the 40D.
If you are happy with your 7D. That is great. I have been waiting for a replacement for my 20D for a long time. When the 50D come out, It is disappointing. Then comes the 7D. It is better than the 50D but It is 18MP. So I gave up and brought a used 40D with only 7K shutter activation.
sounds like the result of you clicking a shutter button is to view at 100% then do nothing with the image.
1. a higher resolution will continue to extract more detail out of any lens. the lens determines the max magnification between sensor size and final image size. This tired reason has been way proven even on photozone when they moved some of their tests from 8Mp sensors to 15Mp cropped sensors if you want empirical data.
2. only if the result of your photo taking is pixel peeping - diffraction and the appearance of it, depends on your sensor to final image magnification - pixel level diffraction isn't a big deal that alot make it out to be.
3. image noise is less on the 7D .. there is a difference.
4. only if you shoot JPG.
5. not at equiv print sizes. DxO mark has them as equal on per pixel and 7D obviously better with matched image sizes.
two ways of looking at this ..
more resolution does not mean that you can increase the magnification of image size to final output size. more resolution means you have smaller graduations and less digital artifacts. you also have more pixels that you can afford to lose to NR at higher ISO's and still achieve a baseline Mp's that a lower Mp sensor could not resolve at even at base ISO.
the more Mp's arguments you raised are all too common, and usually revolve around people that think the be all and end all is to stare at a monitor with the image nailed at 100% magnification.
