Expensive and heavy but my favourite lens.

Excellent for narrow DOF work, paired up with my 500D and I have a take anywhere compact set up.

Supremely wide on the 5D though not the sharpest lens but still very capable.

My most used lens.

I have the non-IS version, bought before the IS version came out. I don’t feel any major need to upgrade to the IS version, though if I were buying again I’d consider it. It is without doubt the sharpest lens I own.
