I purchased the Sony A6000 with the kit lens and the 55-210 lens for travel as opposed to taking my Canon 5DMK2 along with my collection of L series f2.8 lenses. Give the size, it takes great photos but I'm looking to purchase a 18-200mm lens so I don't have to switch between the 16-50mm and the 55-210. There are 2 manufactures which offer the 10-200mm - Sony and Tamron. One of the features I really like with the Tamron is the fact the lens never changes in length whereas the Sony will almost double in length from focal length to the other - 55 to 200mm. What is everyone's opinions of the Tamron vs the Sony lens? I am leaning towards the Sony simply to avoid any firmware compatibility with the A6000 body. I realize Tamron offers a 7 year warranty but not interested in playing the warranty game sending the lens in for repairs/firmware, etc. Thoughts / Advice?
