In my opinion, if Lloyd's 75-300mm was the one that was damaged, I wouldn't fix it. it's not worth it. I'd reckon buying a new lens to replace it, would make more sense. the 75-300mm aint exactly the sharpest lens to begin with and pairing it with the extremely punishing 32mp APS-C sensor of the 90D will make the impurities stand out. I own this lens and have paired it with a less punishing 10mp APS-C sensor, but the impurities are still noticeable. if you want to stick with the 75-300mm, I'd recommend buying another copy to replace it, chances are, it'll cost you more to repair it than to buy a new copy. If it's your 18-135mm that's damaged, then repairing it would make more sense than to buy a new copy.
