Canon 7D with sigma 150mm problem

matt_xyz · #11 (**permalink**) 12-05-2010, 04:05 PM

I used to get an error 99 message occasionally on my old 30D indicating that the connection between the lens and camera was playing up, but only when I used an external flashgun. So it does seem as though a flash can cause strange problems on occasions.

I hope you like your 7D Graham

Thanks Matt, I'm sure I will. Thanks to Roger I already know the AF is far superior to the 40D and that's the main reason I've bought one.
Now I'm considering a new lens. I'm undecided between another 400mm F5.6, or go the whole hog and get a 300mm F2.8.
Min you if my health doesn't improve it'll be a long time before I can use anything much.

Well I have tried the 40D and the 7D with the Sigma 150 and flash today and not had any problems at all.

I'm also happy with the results I got from the 7D with the Sigma today. Guess as Graham said I must have been a bit rusty with the Sigma as it's a while since I used it and I was possibly trying for shots that weren't really on.

I'm convinced it is the flash that causes the problems with the 7D although as I said no problems at all today. I will post some of the shots in the Gallery later and also reply to your e-mail Graham

Got your reply, thanks Roger.

Glad it's working OK, and your happier with the results. No doubt when they're loaded they'll be up to your usual high standard.

Thanks Graham, I think I was a little to keen to say the 7D wasn't as good as the 40D for macro. To be honest the photos I took today with the 7D were better than with the 40D.

I think it was a combination of me trying to get near impossible shots, being a little out of practice with the macro and also a little bit of doubting my own ability to take a good macro shot with the 7D. Anyway after today my confidence in the camera and my own ability to get the best out of it has been restored.

Got my 7D today.Only had a chance to use it in our garden but already I'm impressed with the quality of the rear screen.It's visibility even in bright sunlight really surprised me.

Not many shots yet, but here's one of the first:

Nice one Graham, I'm sure you won't be disappointed with the 7D.

Been out with the 7D and 150mm all day and it's behaved perfectly even using the flash every time.

That's good news. It must have been something simple like a poor contact on the flash hot shoe perhaps.
