8 versus 6

mercphoto

With all the talk about the rumored Canon 20D, just exactly how much extra does 8.2 megapixels buy you over 6.3 megapixels? How noticeable is the difference?

Depends on the size of the sensor (and knowing Canon...it'll be good)...it'll probably be worth it seeing as though they'll add many features...

hardly much difference, but at 16x20 some will notice a difference. at anything smaller, you'll not notice any difference.

Would be interesting to see an image from Canon's current 8.2MP SLR to a 10D, using the same lens, etc. to see the diff. I kinda expected the jump to 8 might not be all that big.

I've noticed 6.3MP seems great for sports, but maybe a touch lacking for serious portraits. Is this why Canon market's their full-frame 11MP SLR as a portrait camera, and seems to have more sports/action features in their 8.2MP camera?

I agree 100%.

Sometimes when you squish too many photosites on a sensor things get noisy and yucky, you never know.

A few things for sure..

The 20d will be black, have the digic II processor, a faster burst, a larger buffer that flushes faster.

For myself, I usually dont shoot rapidly moving subjects so the added features of the 20D would be mostly wasted on me.

I think you would be hard pressed to see a quality difference between a 300d landscape photo and the same shot captured with a 20D.

One of the real differences I notice between the 1DMkll and the 10D, is the significantly lower color noise at ISO 800 and 1600 in the 1DMkll's 8.2 Mp verses the 10D's 6.2. I think the current 10D probably produces better images with 6.2 Mp than most of the 8Mp digicams - because of the lower noise threshold due to the larger pixel size on the APS sensor of the 10D.

Rather than increasing the number of megapixels, I am more interested in whether they stay with the 1.6 Mag factor APS sized sensor, or shift to the 1.3 Mag factor of the current 1D sized sensor. Now that would really make a difference!

I have held off buying an 8Mp digicam at the present time - I keep hoping Canon will build a nice range finder style camera with the 10D's APS sensor - to me, that could be a dynamite little camera. Hint, hint Canon


This is an addendum: There is a multi-page review of the new Canon 20D here

http://www.dpreview.com/news/0408/04081909canon_eos20d.asp

Canon has kept the APS sized sensor, but increased the number of pixels to 8.2Mp.
One interesting feature is an built in B&W mode complete with color filters for B&W of Yellow, Orange, Red, and Green. Now that is interesting.

It also has a new AF system, AND a "Precision Matte" focusing screen which is supposed to make manual focusing easier and more accurate.

And the built in flash is also ETTL-II, just like the electronic flash exposure 1DMKll uses - tho the 1DMkll does not have a built in flash like the 20D.

There is also a new SPeedlite 580EX that takes the sensor size into effect for calculating lens focal length and width of flash beam needed.


Also two new EF-S lenses aimed at the 20D which will accomodate EF-S lenses
first a 17-85mm f4.5-5.6 IS USM - Image Stabilised EF-S lens?? list$599

second 10-22mm f3.5-f4.5 USM list $799


Here is a link to Canon's display of image files from the 20D

This should keep the boards busy speculating for a while

I don't think
I don't think you'll see much of a difference in the photo unless your printing really big or your croping a lot. In those two cases I think you would notice a difference.
I got wind of some kind of B&W mode on the 20D also. Thats sounds interesting.
