Canon EOS 5D Lens Reviews

Canon lens reviews for Canon digital SLR cameras with full frame sensors.
The Canon EOS 1Ds Mk1 - Mk3 and the Canon EOS 5D.

Until Nikon introduced the D3, Canon were unique among digital SLR camera makers in several ways. They used CMOS sensors, where most imaging sensors are CCD, and they made cameras with more than one size of sensor. Nikon are following Canon there too, using CMOS sensors in new cameras like the D300. Most of Canon’s digital SLR cameras, like the Digital Rebel / 350D and the 10D/20D/30D, use a similar APS-C size to other manufacturers - but the Canon EOS 1D Mk II and III use a slightly larger APS-H size sensor and the Canon EOS 1Ds, 1Ds Mk2, Mk3 and the Canon EOS 5D use full 35mm film sized chips. As a result, I intend to test all Canon and Canon fit, lenses with the two main formats - . Edge performance and vignetting - darkening in the corners - aren’t such a big deal with the smaller sensor but are very important with the full 35mm size sensors. So results for the same lens can be very different. Unfortunately there does seem to be a downside to bigger sensors. The problem seems to be extreme levels of vignetting and low levels of sharpness at wide apertures with the very wide angle lenses these cameras encourage you to use again. So is there a problem?
