Resolution Chart Comparison

Shots here are of our new 'version two' resolution chart which provides for measurement of resolution up to 4000 LPH (Lines Per Picture Height). A value of 20 equates to 2000 lines per picture height. For each camera the relevant prime lens was used. The chart is shot at a full range of apertures and the sharpest image selected. Studio light, cameras set to aperture priority (optimum aperture selected), image parameters default. Exposure compensation +0.7 EV to +1.3 EV (depending on the camera).

Measurable findings (three measurements taken for each camera):

Camera Measurement
Absolute
resolution
Extinction
resolution
Canon EOS 400D Horizontal LPH 2200  2300 
Vertical LPH 1800  2300 
Nikon D80 Horizontal LPH 2200  2300 
Vertical LPH 1800  2300 
Sony Alpha DSLR-A100 Horizontal LPH 2200  2900 
Vertical LPH 1800  2800 
Canon EOS 350D Horizontal LPH 1850  2100 
Vertical LPH 1650  2100 

* Moire is visible
+ Chart maximum
LPH Lines per Picture Height (to allow for different aspect ratios the measurement is the same for horizontal and vertical)
Absolute res. Point at which all lines of a resolution bar are still visible and defined, beyond this resolution loss of detail occurs (below Nyquist frequency).
Extinction res. Detail beyond camera's definition (becomes aliased)

If you've read our D80 review then you'll not be that surprised to see these results, exactly the same 'absolute resolution' as the Nikon D80 and Sony DSLR-A100. The only significant difference being that Sony's image processing continues detail beyond the 2300 LPH extinction point produced by the other two ten megapixel cameras. More 'detail' (texture is probably a more accurate description) is available from RAW.

The Canon 400D remains a very good first dSLR, with a balance of automatic, semi-automatic and manual controls to progress through as your creative photography skills improve.
I think it's very important for every Digital Photo Camera!

I think all of the camera makers (Canon, Nikon, Sony, etc.) have been doing the same thing… just making minor, poor, or inconsequential upgrades to their cameras. I think they all got caught blindsided by the smart phone market.

I want to know if kiss digital 400D can be used to shoot videos and movies. Can it also be used to shoot on long hours?
