I am literally panicking because my trip to Japan is in three weeks and I still havent figured out my lens situation for my new a7IV. I spent so much on the body that I need to stay under like $900 for the glass and I really want to stick with Tamron since they seem like the best value right now. I am stuck between the 28-75mm f2.8 G2 and the 28-200mm f2.8-5.6 and I keep switching back and forth every single hour. The 28-75 is obviously sharper and better for those low light street shots at night in Tokyo but then I think about being at a temple and needing that extra reach of the 200mm.

I looked at the 35-150 too but honestly it looks way too heavy to carry for 10 miles a day and it is way out of my budget anyway. My main concern is if the 28-200 is actually good enough or if I am gonna regret not having that constant f2.8 when the sun goes down. Most of my photos will be landscape and street stuff. I dont want to be that person constantly swapping lenses in a crowd because I will probably drop something or get dust on the sensor.

• Tamron 28-75mm f2.8 G2 (pros: sharp, fast, light)
• Tamron 28-200mm (pros: range, versatile)

Is the image quality gap really that big on a 33mp sensor like the a7IV? I am worried the 28-200 will be too soft...
