There have been some people who have been wineing about some pattern noise issue with the 20D...and suggesting that the 10D is better..and has either the same amount of noise or even less, and even go as far as to suggest that the 10D's images look better! Well, this prompted me to do a little test of my own:
Let me provide you with a little background as to what I did. I used a 20D, and a 10D for this test. The 10D is loaded with the latest firmware, the 20D was purchased less than 2 months ago. Both were set on "K" white ballance which both were set to 3000 K. The Parameters on BOTH cameras were set the same which were:
¬*Contrast, = -2, while Sharpness, Saturation, and Colour Tone were set to the middle.
I used a 50mm f1.4 and the same Lexar 512 80x CF card, the shots were both taken on my Gitzo tripod with the identical mounting plates used on both cameras. I used a modeling light from one of my strobes to provide the main light. The second light in the room was from a very dim 40 watt bulb that didn't even record a reading on my light meter.
¬*¬*I set the light off to the side to provide highlights and shadows on my two EOS 1n Film bodies. I used each camera's auto focus to lock on the same point which was the camera on the left's EOS 1n white mark..and then I set both cameras to 3200iso and steadied the camera before taking the shot. Both cameras were exposed at the same exposure settings which were 1/125th @ f4.5 (in 1/3 f-stops).
¬*¬*Both were set to Large fine jpeg.
I renamed the images and saved them as tif files in Photoshop CS...and didn't make ANY adjustments to the images whatsoever. then, I got creative,... I screen capped the pictures side by side on my desktop and converted that screen cap to a jpeg and saved it as a 12 level jpg and then uploaded to my site..
¬*Here it is:
¬*As you can see, the 20D image is a little larger than the 10D image. You can also see that the noise level is much more noticable in the 10D compared to the 20D...and just look at that latitude... again, both cameras were set the same!
¬*¬*The back wall is this ugly wood paneling which has horizontal finnish lines in it already.. so, look in other areas...both sharp and soft areas of the pictures..
¬*¬*Which image do you think my publishers like to have me submit for editorial use??
