Pros: A lot

Cons: Little

Opinion: I don't want to argue at all, but to call this "a decent kit lens.... with a decidedly economical construction" makes me believe that another lens was used... Or the specimen used by Giorgio_Via must be heavily defective/damaged. I have had and have many lenses for both micro 4/3 and FF, but this zoom has a very high overall quality. My specimen has a qualitative yield, even at full opening, which always amazes me.

Pros: I don't know

Cons: I don't own this lens

Opinion: Small consideration without controversy, I can't understand how a person can say that this lens almost sucks in the face of so many other more than positive judgments. Evidently, either on one side or the other, there are those who shoot. Good thing I only trust my opinion! Often some judgments only serve to feed mental. I will never be able to evaluate the performance of a lens from a technical point of view, I generally look at the photo if I like it or not. Mistake?

Pros: good focal range, good sharpness, excellent for both blur and depth of field. Lightweight for hiking and opening

Cons: Awkward flare, certainly not pro construction in the movement of the zoom ring and for the dancing barrel

Opinion: Decent kit lens, although marked PRO does not excel compared to other lenses of the brand. The construction is decidedly cheap, compared to other micro 4/3 lenses such as Panasonic Leica for example. It honestly does its job and, if you find it in kit, it is a good all-rounder. Not to buy if you want an optics to improve. Definitely bad in the flare, forget backlight with sun or lights in the room. The zoom ring (perhaps my sample) is not smooth in scrolling but, above all, the barrel wobbles a bit at full travel. The blur is good and the depth of field is good. I follow my opinion, I emphasize, my opinion, after reading the comments that have followed mine. I have owned and used the lens and I have compared it with other lenses I have had and used, from Fuji to Olympus to Leica. Maybe my judgment is very severe but it must be when a lens is sold as PRO. When I hold a lens made largely of plastic in my hand, I think it is, for the price and for the brand, an unacceptable solution if I want to call it PRO. If I keep the zoom at maximum length and the barrel moves, I do it with all the zoom lenses I've had, Sony Zeiss, Panasonic Leica, I can't accept it, I repeat, for the brand and for the cost and for the PRO definition. The flare is present, too present, maybe in certain photographs it is irrelevant, I think it should be said though. Finally, as far as kit lens goes, as a matter of fact, my OM-1 was purchased in kit form with the 12-40mm f/2.8 PRO II.

Pros: Exceptional construction, ring to switch from automatic to manual focus, top sharpness!, very bright

Cons: personally I can't find any, maybe slightly big for me who has an OM-D EM-10 Mark IV

Opinion: It's a really gorgeous lens, and I honestly wonder how I didn't buy it sooner. The optical quality is excellent: the image is extremely sharp at all focal lengths, with a truly professional rendering. As far as I'm concerned, it's the best lens I've tried to date. The bokeh effect is soft, pleasant and very pleasant, ideal for portraits and isolated subjects. I would like to point out that I also made a direct and in-depth comparison with the Leica 12-35mm f/2.8, a very popular lens, but in the end I decided to choose OM System M.Zuiko 12-40mm f/2.8 PRO II, for the overall performance. Highly recommended for those looking for a versatile and high quality lens.

Pros: It's a pro lens in every sense

Cons: But please.....

Opinion: A beautiful professional lens comparable and perhaps superior to the best zooms of the most famous brands, and a pleasure to use it on om1/2 system, sharp at any aperture, beautiful contrast, light, patch construction, tropicalized, some say that it is an optical project of a few years ago, adding only the tropicalization, zuiko has always made important lenses destined to last over time, so I don't get attached to this chatter.... Looking at the prints, you realize what this lens is capable of! Good light to all!
