Resolution Chart Comparison

Shots here are of the PIMA/ISO 12233 standard resolution test chart (more of which are available in our comparison database). This resolution chart allows us to measure the actual performance of the lens and sensor system. It measures the ability of the camera to resolve lines at gradually higher resolutions and enables us to provide a definitive value for comparison purposes. Values on the chart are 1/100th lines per picture height. So a value of 15 equates to 1500 lines per picture height. For each camera the relevant 50 mm prime lens was used. The chart is shot at a full range of apertures and the sharpest image selected.

Studio light, cameras set to auto, all settings factory default. Aperture selected for optimum sharpness. Exposure compensation +0.7 EV to +1.3 EV.

Measurable findings (three measurements taken for each camera):

Camera Measurement
Canon EOS 350D Horiz LPH 1850  + 2000 
Vert LPH 1650  + 2000 
Canon EOS 20D Horiz LPH 1850  + 2000 
Vert LPH 1650  + 2000 
Olympus E-300 Horiz LPH * 1800  * 1950 
Vert LPH * 1650  * 1950 
Canon EOS 300D Horiz LPH 1600  1900 
Vert LPH 1450  1850 

* 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)
5° Diagonal Lines set at 5° diagonal
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)
n/a Not Available (above the capability of the test chart)
n/v Not Visible (not visible on test results)

No surprises here the EOS 350D delivered exactly the same resolution as the EOS 20D, with one exception, it manages to produce a little more detail near to extinction in the vertical direction. As we mentioned earlier in the review this makes it identical in resolution to the Olympus E-300 and a step up from the EOS 300D. Although it's not a big enough difference for me to recommend anyone to go from the 300D to the 350D on megapixels alone.

Canon EOS Rebel line of DSLR cameras are the best for those wanting to get into more advanced photography. The main reason for this is that they allow full manual controls and the interchangeable lenses. These allow you to change so much of how the cameras functions in different lighting situations.The EOS Rebel T5 is a fast camera, has a huge bright 3.0-inch LCD monitor and exceptional autofocus with a 9-point AF system.One can take beautiful pictures automatically.

Bought this version (Rebel XT) for about $350 two years ago, refurbished. Still works well and has a good image quality.
