Which Tamron lens is gonna be the best all-rounder for my Sony a7IV for a trip to Japan? I'm leaving in like 9 days and I just realized my 24-70 GM is way too heavy for walking 20k steps a day in Tokyo and Kyoto. I've been a prime shooter for years so I'm used to the quality but I need something light and versatile for this trip. I'm looking at the 28-75mm f2.8 G2 because of that constant aperture but then I saw the 28-200mm f2.8-5.6 and now I'm second guessing everything. Is the 28-200 actually sharp enough for the a7IV or is it gonna look soft? I usually do street photography and some landscape stuff so having that extra reach would be killer for compressed city shots but I'm worried about losing that f2.8 at the long end for night shots. My budget is capped at like $900 max since I spent way too much on flights and hotels. Should I stick with the faster G2 or go for the crazy range of the superzoom? I need to order this tonight so it gets here in time to test it before I fly out...

Grab the Tamron 28-200mm f/2.8-5.6 Di III RXD! The MTF data is insane for the price:
- amazing center sharpness
- super light weight
- great focal range Youll save tons of cash!

Like someone mentioned, that superzoom seems tempting, but I was honestly disappointed with the Tamron 28-200mm f/2.8-5.6 Di III RXD after trying it for a week. Its just not as good as expected on a 33MP sensor like yours. The edge sharpness falls off a cliff at the long end, and shooting at f/5.6 in those narrow Tokyo alleys at night is a recipe for noisy, unusable files. Since youre coming from primes, the lack of character in the image is gonna bug you. Id definitely go with the Tamron 28-75mm f/2.8 Di III VXD G2 instead. Its significantly better for:
- Low light consistency across the whole zoom range
- Much faster linear motor focusing for street stuff
- Closer minimum focus distance for food shots The extra reach of the 200mm sounds cool, but the G2 is just in a different league for image quality. Dont sacrifice your a7IVs potential for a convenience lens that feels soft...

To add to the point above: i would really suggest sticking with the Tamron 28-75mm f/2.8 Di III VXD G2 for a trip like this. Since you are coming from a background of shooting with primes, you might find the image quality of a superzoom a bit disappointing once you get the files home on a big monitor. Testing it the second it arrives is a must to ensure there are no manufacturing defects like decentering before you fly out. There are a few things you might want to consider before you pull the trigger:
- Night shooting: Tokyo at night is incredible, but those slow apertures at the long end of the Tamron 28-200mm f/2.8-5.6 Di III RXD will force your ISO way up, which can really muddy the details.
- Reliability: The G2 build quality is a bit more refined for daily abuse in crowded train stations and unexpected rain.
- Sharpness: Since you use an a7IV, you will definitely notice if the corners are soft on those wide landscape shots. That extra reach sounds tempting for the city compression, but honestly, it might be safer to just crop in a little bit if you need to. The a7IV sensor has enough megapixels to handle it easily. Losing that f2.8 light gathering when you're walking through the shrines at dusk would be a huge risk... better to be safe than sorry with your once-in-a-lifetime photos. Dont forget to pack extra batteries since the a7IV eats them up when you're using the screen a lot. Have a safe flight!
