Canon Tele Lenses Views
EF 1200mm 5.6L USM. Okay, so these gigantic and insanely expensive telephoto lenses arene’t popular as such, but always feature prominently in Canon ’s lens advertising. Canon will gladly custom-build one for you, given a prepaid order. I think they run for roughly the cost of a luxury automobile. Frankly if you need this sort of focal length you ’re better off with the 600mm 4L IS USM and a 2x teleconverter, though admittedly you.’ll need an EOS 1V, 1D, 1Ds or 3 to autofocus with it.
Canon make telephoto zooms which fall mostly into two basic categories - very cheap slow lenses with mediocre optical quality and very expensive fast lenses with fabulous optical quality. There are few intermediate choices, though the 70-300 4.5-5.6 IS USM is one to consider. Canon have also never built any affordable long EF telephoto prime lenses - all EF telephoto primes longer than 135mm are L series lenses.
Nearly all large telephoto L series lenses have barrels constructed from solid metal and painted off-white, rather than black plastic or black-painted metal. Canon say they do this since white surfaces absorb less heat than black when used out in the sun, and fluorite crystal lens elements are sensitive to heat - they can expand and contract, altering their optical properties. Of course, the fact that a white-painted Canon lens stands out in the crowd is probably part of the reason as well. Look at any major sports event and yout’ll see rows of hefty white lenses. Though to confuse matters Nikon have also begun to sell some lenses in optional white paint.
The mark II and III versions of Canon ’s teleconverter or Extenders also have weatherproofing. None of Canon ’s more affordable lenses or cameras have weather sealing. Note also that weather-resistant zoom lenses do not have sealed glass ends - you need to put a filter on these lenses to seal out the far (non camera) end.
