Afternoon all, I'm looking to purchase the Tamron 24-70 f2.8 vc, to use on my canon 70d. Read lots of reviews & watched lots of YouTube videos and it seems to be a good one. Can't justify canon price as much as I would like to (brand snob). Has anyone had any experience of this lens? Using it almost solely for portraits. Seems quality issues is the only let down, therefore will probably get from somewhere like Jessops just in case I need to take it back. Any help would be greatly appreciated.
