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 .

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
Pros:cheap, lightweight, fast af, very sharp, very robust
Cons:bulky in the sense of voluminous
Opinion:bought several years ago, I use it very rarely. is the classic plastic 50ino with amazing optical qualities and a low price. it is very light, all plastic except the attachment and the lenses. it is small but I would have preferred it more tapered like the 45mm 1.8 oly. as it is the shape seems to me cumbersome for the optics that is ... but so much so I keep it like this. Decent macro features, blurry good quality. if you like the focal length I can only recommend it as it costs little and does not miss a shot. the evaluation for me must be done between this 25mm 1.7 and the 20mm 1.7. the difference is made by the preference on the focal length and the fact that the 20mm is pancake therefore even smaller. the price is quite similar between the two. the choice is yours
Pros:Good yield and blurry, low price, smooth focus ring
Cons:For the price nothing, perhaps it is a bit bulky compared to the other fixed M4/3 of similar opening
Opinion:It was my first fixed, which I then sold to take the 20mm 1.7. It has a really pleasant yield, good AF and good sharpness, although certainly not at the level of 20mm. It shows some chromatic aberrations that are well corrected by Panasonic bodies and post-production programs. It suffers a bit of focus shift that penalizes the sharpness at intermediate apertures, which however remains always good: test aside, in practice you will never see it. Overall, absolutely, it does not excel in anything but in relation to the price it is a bargain.
Cons:the af is a bit of a dancer in difficult conditions, but then tranqui that hooks it up to you! XD have patience
Opinion:it's a very sharp lens even at 1.7.. to have a higher resolution there is only sigma art. Closed to f 2 does not explain the resolution and the af is very good. The focus ring is also fluid and prof, bayonet is made of metal and therefore good, the best light is obviously that example of fuji 23f2 which is slim and harms the dignity than that of nikons. The blurry is soft and pleasant. The pasty colors obviously beautiful combined with an olympus. go like a train!!
