    This might not be the right place for this, but the forum was super interesting.

    I’m going to Longleat zoo and am looking to rent a telephoto lense for close up of the animals. This is the lense im renting - a canon 100-400 f4.5, I currently have a 5d mk2. Is it also worth renting a 7D for the crop sensor and that little bit extra zoom? Will the f4.5 be low enough to shoot hand held at 400mm in less than perfect light with the 7d? Or should i stick with my 5D?

    Any feedback would be much appreciated.

    Hi Adam:
    You inferred correctly. I'm afraid this is not the correct place to ask this question: this is a technical support forum for Freefly product owners.

    But, in the interests of assisting another photographer, my $0.02 would be:

    1. Don't confuse a crop factor with a zoom -- the 7D only uses the central part of the imaged formed by the lens and thus makes it appear that the lens is zoomed in a bit further when it really isn't. You *might* want to experiment with a Canon ER 1.4x extender (https://www.bhphotovideo.com/explora/content/canon-extender-ef-14x-iii-extender-ef-2x-iii) -- it will give the lens more "reach" but, as I recall they cost you one f-stop.

    2. Your exposure question leaves out one factor -- what ISO setting will you use? If you raise the ISO setting far enough you should be ok with the f4.5, but you'll pay the penalty of a "noisier" image.

    You may find these fora more on-topic for your photography questions:

    Good luck with your zoo shoot.
