Which is better for low light?

The 24-70mm f/2.8 GM II. Its f/2.8 aperture lets in twice the light of the 24-105mm's f/4, so you can use faster shutter speeds or lower ISO.

Is the 24-105mm worth it over the 24-70mm?

Yes if you want more reach and stabilization for less money. Its lowest daily price since 2026-11-04 was $839.95 versus $1,799.95 for the GM II.

Which has better image quality?

The GM II. Its 20-element design with XA and Super ED glass and 11 blades gives sharper corners and smoother bokeh, especially wide open.

Do I need stabilization?

Only the 24-105mm has Optical SteadyShot. If your body has IBIS, the GM II is stabilized that way, but the 24-105mm adds lens-based stabilization on top.

Which is better for video?

The 24-105mm's built-in stabilization helps handheld video. The GM II focuses faster and more quietly, which helps for tracking shots.

Both are dust- and moisture-resistant. The GM II has a fluorine coating on the front element, which helps keep it clean in bad weather.
