70 -300 DO help

Have just bought the lens after much soul searching. I don't know what I'm doing wrong but when I press the shutter half way the camera beeps about 16 times before doing a double beep then the shot is taken by which time whatever I wanted to take has gone elsewhere.
I have set the camera to TV & even P but no difference, it's not on bulb.
Can you please help out an idiot????

Your camera timer mode is set on.

Turn it off. Select Single Shot, or Continuous shot

Thank you, thank you, thank you! I don't know how that happened but you were right. Stress inhibits my thinking and I'm still stressed from buying the lens. I really appreciate your quick response, you've made my day.

It's okay, we all do it sometimes

It's just great knowing there are people here who are willing to help.

I'm surprised this didn't turn into yet another opportunity for people to bash this fine lens...

agreed. it's not soo baddd =)

It's worse when you are at singapore airport and it starts beeping, then speeding up and the cops come towards you until it stops with just a click...
Or at a wedding and you have the beep off so you press the button and WTF my camera is locked up

Heck I've wanted one I think it seems like a really nice discrete telephoto for flowers and such which i shoot stopped down to f/8-f/11.....

Great range, very good IS, good IQ, works with a Kenko 1.4 TC, not white.

I didn't realize you could use a teleconverter on this lens.

Oaktree - does this then become f/5.6-f/8 with use of the TC?

The time I used it the most was an Obama rally. I was about 400-500 ft from the stage so I had the DO on my 1.6 cropped XTi at 300mm with the Kenko 1.4 TC = 672 mm! With the Kenko TC as is (no taping of pins), the AF still worked with no problem with the lens "wide open" >> f/8. I read somewhere that AF does not work with the Canon 1.4 TC.

Even though I still had to crop the shots, I got many decent shots.

FYI: Even though I liked the features of the DO lens, I finally sold it because I couldn't stand its zoom creep and crappy-sticky zooming mechanism.

Imagine my dismay when all my shots kept coming out underexposed for flash at my gramma's 90th birthday, and the trigger on my grip acting funny. The grip issue I realized quickly...

The FEC being under-exposed by 1 1/3 stops I forgot to check... I had been shooting something in E-TTL a couple days before and forgot to reset the FEC.

A LOT of post-processing to correct the problems... and a lot of ruined shots.

It happens.
