The 75mm Summarit M is one of the 4 lenses in Leica's "Budget" Summarit line for M mount. First of all, it doesn't look like your typical Leica lens, as the most prominent feature of this lens is the large rubber grip focus ring. Many Leica purist didn't like anything thats not metal, but the rubber grip is actually very comfortable to use and gives a good grip. The only slight downside is that focusing ring on my copy is a bit firm, should become smooth as I use it more. The build of the lens is typical Leica, doesn't feel any cheaper than other lines of Leica lenses at all. The diameter of the lens is 46mm, and its only slightly longer than the 50mm summilux pre-asph, the slenderness ratio and the weight makes it just right to hold with one hand on the camera and one hand on the focus ring when mounted on the camera. The focus throw is on the short side, but enough to focus accurately, Im not complaining as I like short focus throw.
The image come from this lens is one of the sharpest I have seen, its sharp corner to corner. In terms of sharpness, I would say this is sharper wide open at f2.5 than 50mm Summilux pre-asph at f2. Microcontrast is pretty good too, so you will get a lot of details in your shots.
Look at the detail on the Lantern, this is at f2.5
There are no visible distortion from the shot I have taken so far, no visible purple fringes that I have noticed either.
Now the important part for people who love Bokeh (and we all do). The bokeh from this lens can be smooth. creamy when you focusing on close subjects. But could be slightly harsh when your subject is at medium distances. Overall, its not too bad, If you shoot a lot of portraits and still subjects, the bokeh would be very nice. If you shoot mainly street, then you can occasionally end up with slightly harsh bokeh.

75mm focal length is a bit hard to use at first (at least for me), the reason been its so close to the 50mm frame lines (Leica M9 shows 50mm and 75mm frame lines together), one would mistaken 50mm frame lines for it in a hurry. Although its frame lines are close to 50mm, it gives a lot more compression to the photos than 50mm, so the overall look from it will be different than the 50mm. I have found it to best capture individual subjects, or a cutout of the detail if you are shooting landscape or architecture. Trying to capture the scene or surrounding environment by stepping back don't really work, as theres more compression than 50mm and 35mm. As I use it more and more, I found it more enjoyable to use, it is very different to 35mm which I use the most, unlike 50mm feels like a slight crop of the 35mm shots. After using this lens for a while, I think I have found my perfect pairing, 35mm and 75mm, there are enough difference between them yet they are not too far away from the "normal" perspective, and with both of them, one can cover both wide angle to portrait formal length.
Overall 75mm Summarit M is a great lens, great sharpness, colors, contrast, and good bokeh if you are careful. The build is excellent and I personally find the handling perfect. For a 75mm focal length, you will not regret getting this one. I know theres the more expensive and more perfect 75mm Summicron and Summilux out there, but this is close to half the price of the Summicron, unless you need perfection, I think this lens won't disappoint you.
