Just upload couple more sample picture to see how sharpness of the len.

Great lens, and perfect for zone focusing and street photography. Easy to use, sharp, love the size for travel, I have been using Leica for 25 years and this lens is the best 28mm lens I have ever used and it is on my list of favorite Leica lenses and works beautifully on the Leica ME 240

This is the platonic ideal of a 28mm lens. It is tiny, built like a tank, and now slightly more attainable at retail with this Made In Portugal version.

28 is the focal length for photographers who are immersed in their scenes. During Covid times, this focal length may not be as, um, practical, but it's not a 24! Get in there! The huge depth of field makes zone-focusing a breeze (at f/16-22 you don't really need to focus at all!) and the discreet form-factor begs for an improvisational, playful, and soulful style of photography. More impulsive than intellectual; more Dionysian than Apollonian. People like to talk about modern aspherical Leica glass as being 'too clinical' or something. To that I say: just because it's technically, mechanically, and optically perfect in almost every way, doesn't mean it doesn't have character or soul. That's where you come in, dummy!

This all sounds great, and it really is. But then you consider your M camera with its .72x viewfinder. And you wear glasses and sometimes even the 35mm framelines are a stretch for you... Well, there's a few things you need, if you're like me. There are a few solutions.
If money is no concern: get an M camera with .58x VF magnification. There's the Bessa R4A or R4M. Leica M6's and MP's were also occasionally made with wide angle viewfinders. They will cost you.
A more democratic solution: Buy a plastic Leica Brightline optical hotshoe viewfinder on eBay for ~$200. Glasses wearers can get a 24mm one, like I did, which also has 32mm framelines, so you can compose shots comfortably. Otherwise a 28 will do.

In closing, I think for a lot of people, this may be the only lens you ever need. Journalists, street photographers, or hobbyists who use photography as personal diary need not look much further. At the end of the day, when the dust has settled, it's just a beautiful arrangement of glass for light to pass through.

I took this lens on a few trips and it never left my M7. I love my 50 summicron but this is just the perfect lens for being on the road. It's tiny. When the hood is removed, my M7 + this lens can easily fit in a coat pocket. With the hood there is very little finder blockage at 0.72. Without the hood there is no finder blockage at all. The glass is absurdly sharp and has beautiful rendering.

At 2.8, there if sufficient background separation. You don't get crazy bokeh or anything since it's 28mm but the separation is exceptional. I considered upgrading to the Summicron for the extra stop of light, I decided against it after trying it out. It's twice the size and twice the price, i can handhold at 1/15th just fine with this lens and i don't feel I need the extra stop very often. This is a wonderful lens.

I am using this lens with film--I cant comment on how it goes with digital cameras. Very sharp, consistent lens at all apertures and across the field of view. Quite smooth continuum between in-focus and OOF areas--if youre obsessed with bokeh this might not be the lens you want, though its there on a relatively subtle level. I dont generally splurge on Leica lenses but I do think this one is significantly better than any cheaper options at this focal length. The attached was taken on TMax 100 on a gloomy day with the aperture wide open.

The lens itself is very nice and appears to work well. I am having some photos taken with it developed tomorrow. One complaint: the zipper on the case is defective; it does not zip completely.

I love the small size and superb sharpness of this lens. I usually carry it with the lens hood removed, with just a filter and the metal lens cap that comes with it. Great for street shooting, it is very discreet and the depth of field makes it easy to get accurate focus. With the excellent noise suppression in the M240, M246 and M10, you don't miss the smaller f2.8 f stop compared to the much more expensive Summicron or Summilux.
