Lynne - Is your 24-105 the Canon 24-105 f4 L USM? If so, the Tamron 28-300 mm Di VC PZD is no comparison. You will be disappointed if you "downgrade" to this Tamron lens, which is made to a compromise specification as a "superzoom" all-in-one lens. The Canon f4L is a professional specification lens of very high quality.
If you are really stuck, I suggest the Sigma 24-105mm F4 DG OS HSM. It will match the IQ of the Canon f4L as a 'walkabout" lens.

Take my advice. I'm not using it.
