Main trade-off
Tamron 35-150mm F2-2.8 for Sony E
35 mm may still be too tight for a group. 1165 g stays on the camera even during nearby photos.
Head-to-head
Choose 35-150 when switching between nearby portraits and a farther subject would interrupt the event. Choose 70-180 G2 when a normal zoom already covers nearby scenes and a shorter dedicated telephoto fits the bag. The 35-150 weighs 1165 g. A 540 g 28-75 G2 plus the 855 g 70-180 G2 totals 1395 g before accessories, but that two-lens kit also covers 28 mm and 180 mm. The single lens is not an equivalent range replacement.
Before you choose
The 35-150 is 310 g heavier than the 70-180 G2 alone. Add a 540 g 28-75 G2 to the latter, however, and the two lenses total 1395 g, which is 230 g more than the 35-150. That is a useful comparison for an event where both lenses would genuinely be carried. It is not equivalent coverage: the pair adds 28-35 mm and 150-180 mm. Accessories, camera and support are excluded. Choose the one-lens route only if the missing endpoints do not create another purchase or swap.
What this is based on
Event bag plus nearby/far coverage crossed with exact three-lens masses and unequal range boundary. 540+855=1395, 1395-1165=230. No equal-performance claim.
Main trade-off
35 mm may still be too tight for a group. 1165 g stays on the camera even during nearby photos.
Main trade-off
70 mm is too tight for many nearby scenes, so the normal lens and a safe place to swap may still be needed.

Tamron 35-150 vs 70-180 G2 for events and a two-lens family kit. Compare interrupted lens changes, complete bag weight and close-detail work.
Observed buyer discussions compare a 35-150 one-lens event approach with adding a 70-180 to an existing normal zoom. These exact Sony E offers share bright portrait coverage but solve different kit-organization problems.
Winner by situation
35-150 covers more of that sequence while mounted.
70-180 adds a dedicated longer, stabilized range.
70-180 has the stronger wide close-up setup.
The specific 28-75 plus 70-180 pair covers both endpoints, with extra mass and a swap.
What matters in practice
The 35-150 is 310 g heavier than the 70-180 G2 alone. Add a 540 g 28-75 G2 to the latter, however, and the two lenses total 1395 g, which is 230 g more than the 35-150. That is a useful comparison for an event where both lenses would genuinely be carried. It is not equivalent coverage: the pair adds 28-35 mm and 150-180 mm. Accessories, camera and support are excluded. Choose the one-lens route only if the missing endpoints do not create another purchase or swap.

A nearby portrait can turn into a farther candid before there is a convenient place to put down a bag. The 35-150 covers that transition while staying mounted. The 70-180 starts at 70 mm, so a nearby group can require the normal lens again. If the event offers predictable pauses and the normal zoom is already owned, the two-lens route becomes easier to justify. Neither range excuses leaving a child unattended or changing equipment in an unsafe position. The advantage is fewer equipment transitions, not guaranteed missed-shot prevention.
One-camera event plus interrupted access to a bag crossed with 35 versus 70 mm starting range and two-lens ownership. No invented time saving or safety guarantee.
The 70-180 G2 reaches 1:2.6 at 70 mm with about 12 cm front clearance. The 35-150’s endpoint ratios are substantially lower. A photographer who also records small decorations or handmade products can get a useful close-detail job from the telephoto already in the two-lens kit. It remains a wide-end setup and needs light access and sufficient depth of field. The 35-150’s broader portrait range should not be described as replacing every task the separate lenses can perform.
Event portraits plus occasional craft/detail work crossed with exact close-up ratios and Tamron front-clearance qualification. No dedicated macro or optical-quality equivalence.
Tamron, AFA058S700
Move between 35 mm portraits and 150 mm framing without a lens change.

Tamron, AFA065S700
Add a shorter stabilized telephoto to a normal zoom already owned.
Meaningful differences
| What changes | Tamron 35-150mm F2-2.8 for Sony E | Tamron 70-180mm F2.8 G2 for Sony E | Why it matters |
|---|---|---|---|
| Nearby-to-far sequence | 35-150 mm F2-2.8. | 70-180 mm F2.8. | 35-150 can avoid a normal-to-telephoto swap, while 70-180 reaches farther. |
| Lens mass and filters | 1165 g, 82 mm thread. | 855 g, 67 mm thread. | The dedicated telephoto is lighter alone. A complete two-lens bag is a different comparison. |
| Example complete lens set | One 35-150: 1165 g. | 28-75 G2 plus 70-180 G2: 540 + 855 = 1395 g. | The single lens saves 230 g against this specific pair but has narrower total coverage. |
| Occasional detail | 1:5.7 wide, 1:5.9 tele. | 1:2.6 wide with about 12 cm front clearance. | The dedicated telephoto has a stronger wide close-up ratio despite starting at 70 mm. |
What you give up
Recommendation switch
Choose Tamron 35-150mm F2-2.8 for Sony E. The one-lens range removes that equipment transition.
Choose Tamron 70-180mm F2.8 G2 for Sony E. The separate telephoto preserves useful endpoints and close-up capability.
What matters in practice
The heavier single lens can make the total event bag lighter, but it gives up both the wider normal view and the longer telephoto endpoint of a two-lens kit.
