When we asked fine readers like yourself how you'd improve the EOS-1D Mark IV and Rebel T2i not a soul mentioned manually exposed video, but if you were personally plagued by a jittery aperture when shooting said footage with certain lenses (a bug that previously appeared in the 5D Mark II ) you'll be happy to hear Canon diligently decided to fix the issue anyhow. The 1.0.8 firmware updates for both aforementioned DSLRs are now available at our source link, but unless you've personally had a problem they may not be worth your time; Canon's changelog shows aside from fixing a few menu misspellings, the new code does absolutely nothing else.
