Camera Labs

Hi Guys, I plan to get the 40D at some point, but would like to walk around with 1 lens if possible and the Tamron 18-200 looks purdy good. However during last week, when I was shooting with 30D and a Tamron and Sigma lens, after a day of shooting with Sigma, the camera didn't recognize the lens anymore and I got it a Err message of death (99).

Is this a rather common thing? Are we forced to use Canon lenses only, to avoid the derided Err 99?

Nikon makes a great 18-200, but Canon does not. And there is not a single lens in Canon that goes from around 18 to over 85mm.

Is there an after market company that's superior to Tamron and Sigma that I've missed.?

Lastly, am I the only one who thinks Tamron makes a superior product to Sigma? The sigma lens that I have initially had to be sent back for repair under warranty and of course then I had the problem of 30D not recognizing it.

Thanks for the comment guys... S

Hi SHIVA, quick answer to your first question: I believe error 99 means the contacts between the lens and body are dirty... (or faulty)

thank you very much... S

When Klaus Schroiff did his test of the latest Tamron here, he came out with quite a positive view of this 18-250mm. BUT this one has no IS! So if you want IS plus super-zoom on the Canon you're still stuck with the Sigma 18-200mm OS that has quite some flaws! See Klaus' test here for comparison.
