Pros: Sharpness - Good Bokeh - Compactness and lightness - Working AF tracking

Cons: AF Slowness

Opinion: I've only had this lens for a few days, but I've used it a lot because it's addictive... Combined with an Olympus PEN E-P7 the result is very compact, camera body and lens fit in a sweatpants pocket. The lens is very defined already at full aperture, soft and mellow bokeh, with a good progression of planes. The AF is slow, but absolutely acceptable, noisy, for me it is not a problem since I use it only in photography, AF tracking WORKS, even with face/eye recognition. Minimum focusing distance of 20 cm, I also like it for ambient portraits and close-ups, I have to test it well in landscape and street, but the premises are excellent. From the point of view of construction it is less plasticky than I expected, bayonet and barrel are made of metal, Made in Japan. Recommended purchase, a must buy faithful to the M4/3 philosophy.

Pros: Size, lightness, versatility.

Cons: Speed ad. Addiction to always having it with you

Opinion: It is about the same size as a cap or adapter ring. Very sharp, it doesn't have a beautiful blur but that's what you expect from a 1.7. Low price. In the camera bodies the small size makes them compact. They fit in the pocket of the jacket or even the trousers if it has large pockets. Must have. The 20mm teaches you how to photograph. A step back x the reportage of the 17th. One ahead for the first portrait of the 25th.

Pros: Compact-sharp-bright

Cons: AF in video

Opinion: In my opinion, it's not good for videos. In manual focus yes, but in auto focus absolutely. Very slow and inaccurate. For photos it doesn't go AFC. In single-player mode it works well although slightly slow. I tested it on Panasonic GX80 E yes Olympus OMD EM10 Mark 4 Honestly there are no differences: It's fine on both bodies. Very sharp, bright and has a perfect focal length for street but you can also take portraits. Then the compactness on small bodies is the top.

Pros: All

Cons: Autofocus a little slower

Opinion: I own it together with the Summilux 25/1,4. They can coexist. The 20 has on its side the practicality: mounted on a GX9 is discreet and extremely portable. The difference in brightness is irrelevant in practical use and the "yield", the person responsible for the sleepless nights of the amateur photographer, is excellent in both I also have an excellent G9 machine that can certainly not be defined pocket and on this the summilux goes perfectly. The above when I want to play HC Bresson on duty... for everything else there is the Panaleica 12-60 zoom. I dare say that the choice of objectives rather than technical is philosophical. Returning to the 20mm I recommend the 'purchase. In the used car it is at prices that are too close to the price of the new: I would not pay even one euro more than the current 200, including any expenses. However, to be on the side of those who sell, it seems that they go away even more than 250 euros ... What can I say, happy with them...

Pros: Compact, really good image quality, great all-rounder for reportage

Cons: Autofocus not at its best, chromatic aberrations in backlight

Opinion: I had the first version that I resold when I bought the 25 1.2 olympus, but I discovered that in many situations I missed it, such as outings with two lenses only or reportage with only one fixed. I happened to have an opportunity for 160 euros I took the II version, the af has not improved and the aberrations are always the same, but the merits are all confirmed, I also recommend it as the only fixed for reportage to be coupled to the zoom, even in Ta has a very good yield. My judgment applies only to photography as I do not make videos and I can not tell you if it is indicated.
