Review

The Summicron S 100mm is the only large-diameter Leica S lens.
For me, among the genuine Leica S lenses, the Super Elmar S 24mm and the Summicron S 100mm were the two lenses I wanted to try.

When I acquired the 100mm, there were 24mm lenses on the market at a similar price, but I still couldn’t resist the appeal of a large aperture lens. Perhaps the timing was just right, but I found one for about the same price as the CONTAX 645 Planar 80mm, so I was determined to buy it, so I got it. The Leica Red Dot Forum says it’s 100CRON.

After the purchase process, I was shocked to see a rich person on the Leica Red Dot Forum say that the autofocus is completely destroyed, that no matter how much I adjust it, it doesn’t work, that the S Typ007 doesn’t work, but that the S3 is OK. I felt a little regretful after seeing the negative reviews, but I decided that I wouldn’t know until I tried it myself, so I took the lens with me and went outside. My worries were almost unfounded, and the results were excellent.Although materialistic correction was included, I was satisfied with the product.

Autofocus (hereinafter referred to as AF) is also fine so far, and as someone who is used to using heavy AF cameras and lenses, I don’t have much to complain about. Regarding AF, he doesn’t really agree, but he might be wrong to think that focusing is easy with the mid-sized 100mm F2. I’m glad it wasn’t released exclusively for manual focus (MF).
If Leica S doesn’t work, the adapter is expensive, but if you use the S-LENS Adapter-L (16075), you can use it with L cameras as well, making it versatile. Looking at the number of units manufactured, it doesn’t seem like there will be 500 units, so if you own a complete set, it may become expensive in the future.

Compared to Hasselblad’s HC100mm F2.2, this native lens has faster AF. However, compared to the fast focusing speed of a 35mm lens, it is clearly slow.
I experienced overfocusing several times, but if you aim at high contrast areas, there are almost no problems. You’re more likely to miss when the light is low, but it works best if you aim at a place with as much contrast as possible. In the end, it’s a matter of usage.

The minimum focusing distance is 0.7m, making it a lens that can get close for a lens with a focal length of 100mm. Hasselblad’s 100mm is only 0.9m, so this 20cm is very valuable.
It’s not labeled with APO, perhaps because in unfavorable situations a purple tinge may appear at the edge of the light, but under normal circumstances you won’t notice any color bleeding, so perhaps adding APO to the product for marketing purposes could raise the price. I would like to thank you for your kindness in releasing it as a regular Summicron.
