Quality lens. Hope Pan expands this line!

This lens is perfect for the S9, and any body where you want a light but competent lens. It represents a new lens class that is missing from L mount. AF is fast, IQ is good. F2 is fast-ish, a happy tradeoff to keep it small. The way I shoot I don't use the extra controls on the lens, but many users will enjoy a free open button and an AF/MF switch, especially on the S9. The 144g weight plus quality of this lens makes it like a micro four thirds lens experience which is groundbreaking for full frame. On the S9 this is nearly the same footprint as my GX9 + 20mm f1.7. I don't miss a lens hood and work around it rather than be saddled with it. At this price point you might normally expect a hood, but I don't for a pancake.
This is a missing class of lens that L mount needs, particularly for lightweight bodies, travel, street, etc..., a compact line of polymer based F2 primes. Sigma offers the Contemporary line that includes F2's. It is compact but the all metal construction results in weights of 370g+ each, all of them heavier than the Pan 20-60mm kit zoom.
Panasonic's polymer is not cheap feeling and high quality, they should lean into that and expand the 40mm into a compact F2 prime line with entries like: 20mm, 24mm, 28mm, 35mm, 40mm, 50mm, 85mm all targeted into a 140g-220g range and optimized to be small, light, and useful like this 40mm.
Very pleased with my purchase.
I would recommend this to a friend!

Great lens just need a lens hood

Great to see now the lens are much lighter and easier to carry. F2 vs F1.8 not much difference, especially when the weight reduction is huge.
Just one complaint that it should come with some lens hood. Or Panasonic should sell the lens hood separately. Any 62mm lens hood works which is good.
I would recommend this to a friend!

Hi there! Thank you for the thoughtful review. We’re glad to hear the lighter design and portability have made a noticeable difference, and that the F2 performance is meeting expectations. We also appreciate your feedback about the lens hood. It’s helpful to know that including one would have added value to the overall experience, and we’re grateful you took the time to share that perspective.

Bought this lens for my S9 and couldn't be happier. It takes amazing photos in spite of being so compact. It also has relatively good autofocus although I still use manual focus when trying to really nail a specific focus point or when im shooting burst. I couldn't be happier with this lens, zero regrets.
