Leica 28–70mm vs Sigma 28–70mm – Is the Leica Worth the Price?
In this video, I compare the Leica Vario-Elmarit-SL 28–70mm f/2.8 ASPH with the Sigma 28–70mm f/2.8 DG DN Contemporary. Both lenses cover the same focal range and aperture, but the question is:
Does the Leica really justify its much higher price tag?
Or is the Sigma the smarter choice if you’re on a budget?
I go through build quality, handling, image quality, autofocus performance, and overall shooting experience to help you decide which lens is the right fit for your photography.
If you’re a Leica SL user or considering the L-Mount system, this comparison will give you practical insights before making your choice.
