    Hello all,

    Well after a bit of research and some advice from the Club i decided to buy myself the 70-200mm F/4 L Non-IS (due to mother-in-law taking our Christmas presents back and giving us the cash (plus £100 from me :) ).
    The reason i didnt go for the f/2.8 is price and weight. And the reason Non-IS over the IS version is because now i can afford a 1.4x converter and plethera of filters.

    Anyway the Club suggested that the IS is cancelled out by the ISO handling of the 40D and i thought i would put this to test.
    I sat on my sofa in dim light (closed all curtains bar 1 behind the subject, and put a lamp on next to it) and took a photo from about 5 metres away.
    All handheld
    Here are my results.

    I hope it helps someone make a decision on which 70-200mm to buy.

    Super - you got one. Looks like good results there as well - you can clearly see the camera shake in the first 3. It's looking nice and sharp by ISO 800. Better to have a sharp but noisy photo than a blurred by noise-free one.

    ISO 800 looks perfectly respectable as well.

    All you need to do now is remember to up the ISO when you are taking pics!! I always try for at least 1/200th when using my 70-200 and if I run out of aperture I'll start bumping up the ISO (though my 1D does this for me and I think your 40D can as well??).

    The 40D does 'auto-ISO but it's either 400 or 800 only. Not sure if the safety shift helps there?

    I set it to Auto ISO and generally indoors sets itself to 800, which doesnt look bad at all.

    And yes, i got one which will now finally complete my set of lenses, and wont need to buy another one (famous last words).

    I got it for teh Guildford trip and the march in a couple of weeks.

    Usefull, with IS (and a still subject) you could have got that shot solid at ISO200 or so. Thanks!

    Yeah, but in the OP, its not worth it for another £250-£300.
