Afternoon,
If I were to purchase a brand new lens from Canon/Sigma/Tamron, etc., and found it to be front/rear focusing, would sending it back to the manufacturer for recalibration be covered by the warranty????
Thanks

The same applies to lenses as every other item purchased from a retailer - if not of the quality described, it should be replaced and no questions asked if new. On the other hand, if in warranty and over a reasonable age - say 28 days - it is up to the seller to get a faulty item repaired at no cost to the purchaser.
