Pros: 120 euros of amazing goodness

Cons: nothing really

Opinion: Bought it to replace a m4/3 Panaleica DG 25 f1.4 that I did not really bond with . Hesitated between this and a Sigma 30 f1.4 , or a Oly 20 mm f1.4 , but the price second hand was the decisive factor . 25 mm can do 30 with a little crop, can't do 20 mm though but the Oly is too expensive. I had never paid particular attention to this lens, I was prisoner of reviews that put it down as cheap and flat , how mistaken I was . First the size : nearly perfect for me . Build quality ok nothing to complain . Output : nice coulours, not as saturated as the Leica series, but for me an advantage in low light . Sharpness already excellent at f1.7, f2 does not bring a significant improvement ( as opposed to Oly 17 mm f1.8 for example ) , f2.8 and beyond excellent . This is a lens you can happily shoot wide open , most important for me as I intend to use it on street night shots , along with my 45 f1.2 . AF no problem , even in low light . Comparison tests : this humble Lumix is as good at f1.8 as my old Panaleica 4/3 D 25 mm , which tells volumes because my old 4/3 Leica is really good , better than the m4/3 version ( I keep it for portraits ) . As good as my Panaleica 12-60 f2.8-4 at 25 mm f3.5 but not better. Both Leica lenses are a bit more contrasty though , nothing important . Some purple fringing in high contrast situation , I don't really care . Very happy with my purchase .

Pros: Sharp, lightweight

Cons: I don't see any

Opinion: I've had it for almost three years and I can say it's a great lens. I don't understand those who complain because they are "plastic"... but precisely for this reason it is light (even if in metal it would not weigh twice as much). I use it on a G6 and it gives me beautiful, sharp, perfect colors. It's just a shame that the price continues to increase, to date it already costs almost 20% more. True, everything increases: we want PEACE or goals (or air conditioners)...

Pros: Lightweight, economical, more than decent optical performance, uniformity across the entire frame

Cons: Muted colors, lack of button to switch from autofocus to manual, bulk, no tropicalization

Opinion: Lens that costs little and is fine, a great purchase if we balance price and performance. The AF works very well in daylight conditions, sometimes it struggles when you insist on wanting to shoot at night: that's why switching to manual focus with a special button would be very convenient, instead you have to do it from the camera's menu. Quite contrasted, however, it returns soft colors that are sometimes too muted. Sometimes it gives the impression of being a bit soft, but then you realize that this is not entirely the case. It is appreciated for the uniformity between the center and the edges of the frame even when the aperture is wider. A lens that I bought some time ago, but that only recently I decided to try seriously, finding it better than how I perceived it at the beginning. Recommended for those who want to travel light, but it is not as compact as other fixed lenses on this format. Definitely a "best buy" even if there is better around: it still allows you to work well with little expense.

Pros: One of the most economical autofocus lenses in the micro four-thirds lens landscape with this aperture

Cons: I don't know in relation to the price

Opinion: Those who land in the micro four-thirds world cannot help but own this little gem, light, with a large aperture, relatively sharp, but above all with an almost ridiculous price given its characteristics and its image quality. With an equivalent focal length of 50 mm it gives portraits with pleasant blur and with a completely respectable sharpness, it comes with a lens hood, which is not exactly taken for granted in the micro four-thirds world (see Olympus equivalents). Given its price, I really don't know how to find fault with it and I can only recommend it to anyone who owns this system.

Pros: Cheap, all in all well built. Silent Af

Cons: Open focus shift between f2 and f5.6 with peak at f4

Opinion: Affixed to the lumix 20 after a few tests I kept the lumix 20. In the resolution of small details (conferring them on the same subject on equal terms) I found it clearly inferior to the pancake. I think it depends on the focus shift that makes this lens from f2 to f5.6. At f4 you can quite notice the drop in sharpness. I used it on pana g80
