Im honestly getting so frustrated with my current setup and Im about ready to throw my camera bag out a window. Ive been using the kit 20-60mm on my S5II for a few months now and while its light it just doesnt have the reach I need for anything and the constant lens swapping is driving me crazy. I also have the 50mm 1.8 but every time I have that on I wish I had a zoom and when I have the zoom on I wish it was faster or longer. Im heading to Kyoto and Tokyo in about three weeks and I really dont want to be fumbling with caps and dust on the sensor while Im trying to enjoy the trip with my kids. I need one lens that can basically live on the body for 90% of the time.

Ive looked at a few options:

• Sigma 24-70 f2.8 Art
• Panasonic 24-105mm f4
• Sigma 28-70 f2.8 Contemporary

The Art lens seems heavy for a full day of walking and I dont know if the 24-105 is fast enough for night shots in the city. My budget is around $1300 but I could stretch it if the quality is actually worth it. I just want something sharp that doesnt feel like a compromise every time I press the shutter. I just want to focus on the photos instead of my gear for once. What is the absolute best all-around zoom for the S5II that wont make me regret switching from my old Sony setup?
