Amongst the various Canon telephoto lenses what do you reckon are the current best options for use with a 1V? Mostly looking to use for grabbed landscape shots (things you see whilst driving around with the camera slung in the back), hiking short to medium distances and secondary uses a little of everything one would use such a lens for (motorsports, wildlife, aircraft). Mixture of colour slide and B&W film. Will also be a mixture of handheld and monopod, big fan of monopods. It occurs to me that for a film shooter, looking for a deal on the 70-200 F2.8 L IS USM II is still the king. However they seem to be about twice the price here of the same lens in its F4 incarnation. The 100-400 options seem very popular but they are f5.6 and one could do the same with the 70-200 F2.8 and a 2x teleconverter (and of course benefit from the F2.8 when not using the converter). Only looking at secondhand, so many of these lenses available in mint to near mint condition it seems crazy to pay new retail prices. Purchase price for me is more of a question of retained value and usability than the raw number. Decisions, decisions. Would be interested to hear of your experiences on film EOS cameras.
