I was a fan of Tamron 18-200mm lenses for my Canon Rebel 5ti camera. for good all-purpose lenses that would save me from constantly changing lenses. Well, alas, this proves - you get what you pay for. I've been in photography for almost a decade. Every photo I took was absolutely BLURRED. From a practice session of several hundred photos, I couldn't get a clear, sharp shot. What a disappointment. You can literally see the glass lenses inside physically move as you try to adjust focus. NOT worth the money, time or frustration. Stick to brands.
