The Panasonic 16-35mm F4 Lens Focuses Crazy Fast Now

The Panasonic 16-35mm f4 lens review has been updated to reflect recent changes.

For a while, the Panasonic 16-35mm f4 Lumix S Pro was one of the L Mount’s fastest focusing lenses. Then that changed with the introduction of a few primes. But with the recent Leica SL2s firmware update, we’re updating our 16-35mm f4 review. The lens is even faster than it was before, and we’re not honestly surprised by this. Technically, it means that this lens is an absolute cheetah when autofocusing. In practice, that’s indeed true. Also true is the fact that people don’t really need super-fast autofocusing motors when using wide-angle lenses. It matters a lot more with telephoto lenses.

The Big City Lens: The Panasonic 16-35mm F4 PRO Review

The Panasonic 16-35mm f4 PRO is very nice, but it’s not outdoing Sigma’s 14-24mm f2.8.

When we called the Panasonic 16-35mm f4 PRO lens in for review, we were pretty excited. Panasonic has done a positively stellar job of designing lenses for the L mount system. But when looking at prices, I was scratching my head. One would think the Panasonic 16-35mm f4 PRO would be the affordable wide-angle zoom amongst the lineup. But the truth is it isn’t. Sigma’s 14-24mm f2.8 is a bigger lens that lets more light hit the sensor, and it’s more affordable than the Panasonic 16-35mm f4 PRO. As I sit in my office typing that sentence, I’m still perplexed as to why. The Panasonic is an excellent lens in every single respect, but I would sooner reach for an f2.8 lens if I could. That’s also not to say that the Panasonic 16-35mm f4 PRO isn’t a great performer. In fact, it’s exceptional.

Update May 2021. We’ve made changes to this review. You can track them in bold and italics.
