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.
Cons:For some lack of AF-C and focus ring a bit 'inconvenient to use because of the very small size of the barrel
Opinion:I bought this lens, new, for only 199 euros with 4 years of FOWA warranty. Aesthetically pleasing in silver color, I find that it has an excellent sharpness and yield in relation to the price. Full opening cartoon, although for me more than a con is a pro because it gives a nice mood to the images. The aperture is a bit slower to close than other lenses so shooting at closed apertures (at TA obviously not) you feel a slight shutter delay. It has the angle of view of a 40mm on FF which, for me who do not particularly like wide angles, represents the maximum versatility: I prefer it to the 50mm that in some contexts is narrow and to the 35 that can be a little too wide. The AF on my GX80 is slower than other lenses but much faster than I expected and the lack of AF-C, for the use I make of it, does not interest me. I noticed though that it is extremely accurate, more than the 25mm 1.7 and the 45mm Olympus. Its biggest advantage, however, is the fact of being pancakes: combined with a compact body type GX80 allows you to have the camera always with you, in a small bag or in the pocket of a coat, greatly increasing the chances of devoting yourself to photography. Now I use almost only this!
Pros:A small jewel, bright, light and of the highest quality
Cons:It does not go to AFC (patience, it is not a lens for action)
Opinion:I use it on a Lumix GX9, only for photographs, I don't make videos. On the GX the focus is instantaneous in single shot. Ok, it's a bit noisy, but not making videos is not a problem. The quality is really excellent. The focal length is excellent for most situations: landscape, set portrait, street, reportage. I absolutely recommend it
Opinion:It's the only lens I've resold out of desperation. I may have been unlucky, so maybe not everyone is like that. Before taking it I had read on the net that it gave bands at high ISO, but I have never seen defects of this type. I used it on an Olympus E-M5 MKII and it was a tragedy the focus. I state that this camera has in itself a really ridiculous focus for the price it had. Since the lens has a 1.7 aperture I bought it exclusively to take family photos at home. The focus with the low lights was not the best and in any case the photos were never sharp, had some problems my specimen I think. When I sold it, a videomaker with a Panasonic took it and he also noticed that the focus was not precise, but he used it manually, so the problem was quite relative. Then I repeat, maybe it was my defective specimen. If you are in my condition I do not recommend it. If, on the other hand, you do street and use it mainly during the day and with diaphragms a little more closed than 1.7 it is an excellent lens, it has few defects, especially for what it costs. If you have to make the use that I made of it I recommend the panaleica 15mm 1.7 (if you are not short even the Olympus 25 1.8 is excellent). It is true that it costs much more, but at least the photos come as they should come and the keding is also correct. So if you want to use it as a handyman it is excellent. If you use it mainly because you need the 1.7 then better other goals.
