Which is better for wedding photography?

Both, usually together. The Sony covers group shots and the room at 24-70mm; the Tamron covers tight portraits and ceremony reach at 70-180mm. If you can buy only one, the Sony's range is more versatile for a single-lens day.

Is the Sony worth the extra money?

If you want one fast standard zoom with the best autofocus, close focus and sealing, yes. If you mainly need telephoto reach, the Tamron delivers f/2.8 at 70-180mm for $999.00 at Adorama as of November 4, 2026, versus $1,829.99 at eBay for the Sony.

Which has better stabilization?

The Tamron has built-in VC; the Sony has none and relies on the camera's in-body stabilization. On a stabilized Sony body the gap narrows, but the Tamron still helps at long focal lengths.

Can I use the Tamron on a Nikon camera?

Yes, a Nikon Z version exists. The Sony FE 24-70mm GM II is Sony E-mount only.

Which is better for portraits?

The Tamron, for its 70-180mm f/2.8 range and compression. The Sony works for environmental portraits at 50-70mm but cannot reach 135-180mm.

Which is easier to carry all day?

The Sony at 695 g is lighter and shorter. The Tamron is about 855 g and extends further, so it balances less well on small bodies.
