Picked up my new 70-300 F4-5.6 L IS USM (and 7D this Thursday).
One issue (or may not be?) is the Focus Ring.
Mine has some minor play and you can hear this play, but its slight.
Obviousy I would like to know if this is normal [If it is normal, I would be happy to accept it as it's not bad to live with] but need to know if anything is wrong?
So any owners please respond and describe how yours is [feels and sounds - as much detail as possible please]
Description of issue below:-
a] If say, you try very gently to move the focus ring up and down [vertically] around the shaft of the lens or
b] slightly wiggle the focus ring to and fro, holding it with thumb and index finger [around the length of the shaft] you can see a tiny amount of movement and hear the play. Were only talking a very small amount but you can hear it [a sort of fairly faint tuck tuck/ ever so quiet clunking noise at each end of the play].
The ring actually rotates very smoothly once in motion, it only has a slight wisper sound [LIke well greased bearings] as it rotates [So that sounds fine].
This sort of play seems a bit like steering wheel slap but the very start of a problem - obviously much much quieter. Its as though the ring is a fraction too big for the shaft.
You can also see the tinyiest amount of movement if you pull and push the ring [extremely gently] from one end of the lens to the other.
Maybe to put it in perspective, it's noticable because of the comparison with the Zoom ring, which has NO PLAY whatsoever; and is super smooth, but just the perfect amount of resistance [LIke you feel it is running on zero tolerance ball bearings packed in grease - all you hear is a sort of whisper of greased perfectly machined bearings]
I guess I'd know I had a problem if say other owners said my focus ring looks, sounds and feels like the zoom ring does [assuming your zoom rins was perfect like mine]
Otherwise pretty pleased with it so far - focuses pretty quickly and even in low light- does OK.
