Looking to buy a lens for my T4i. These are the two that I am considering. Tamron 18-270mm F/3.5-6.3 DI-II VC PZD Piezo Drive Ultrasonic Motor Aspherical (IF) AF Zoom and the Tamron SP AF70-300mm f/4-5.6 Di VC Ultra Silent Drive (USD) Telephoto Zoom.
My biggest concern is the weight of the 70-300. It wouldn't be my walk around lens. I just need more zoom than I have now, which is the EF-S 18-135mm IS STM.
Would I miss that extra zoom on the heavier lens? IQ about the same? Anything else I need to consider?
Any input on these two lenses would be greatly appreciated.
