I've been shooting with a Canon 5dMK2 with L series lenses but bought the Sony A6000 for travel use. The Sony A6000 is the perfect setup with the 55-210mm lens but I wanted the Sony SEL18200LE to avoid lens swaps. I picked up the following 3 Sony lens today. SEL1670Z $770 SELP18105G $450 SEL18200LE $630 Now I have to make the difficult decision to pick 1 or 2 of the lens to keep. I like the size & weight of the 16-70mm f4 but not the range. I like the range of the 18-105mm f4 but not the size or weight. The 18-200LE is a great all around lens but hoping for a f4 lens vs a floating f stop. Return policy is 10 days, so I have have 10 days to make a decision. Any advice you can give me will be grateful!
