Canon 70-200 f2.8 IS Mk 1

[Gidders]

I've bought one of these off ebay which arrived this morning.

The lens is is great condition but..

when I part press the shutter release there is a click which sounds link a servo as the IS motors activate (followed by a faint hum or whirr as the motors do their stuff)

I have a 24-105 IS and 70-300 IS (non L ) and while I get the motor hum, I don't notice this click.

Is this normal for the 70-200?

Mine makes a clicking noise when the IS is activated. I bought mine new about 4 years ago. Whether it is supposed to or not, I don't know.

There again I think all of my IS lenses click when IS is activated.

[john crossley]

Yeah, I've just checked and they all click when IS is activated.

just stuck mine to my ear and it does seem to click before humming... no idea why but I guess it is just the way it is with that lens. I'm sure you'll love the lens, I got one last year (changed up from the non-IS f4 version) and have been so impressed with it. Definitely one of my most used lenses.

Thanks for the reassurance guys ... now how soon does it start getting light in the morning

You should send it to Canon service! That hum can be a mallfunction of IS motor! Be very carefull!

Very early, I was out trying to get the milky way the other night, it was still light at nearly 11pm and reckon it is still starting to get light around 4 -4.30am.
