A versatile all-around lens, the Summicron-M 50mm f/2 from Leica is a normal-length prime featuring a fast f/2 maximum aperture to benefit working in low-light as well as offering greater control over depth of field. A six elements, four groups optical design provides even brightness and sharpness across the image frame, and also helps to virtually eliminate distortion for clean, natural rendering. Beyond its optical performance, the lens is also compact for everyday use, its manual focus design permits working with subjects as close as 2.3', and it has a built-in expandable lens hood to prevent lens flare and ghosting.

Q: 5. I am debating to buy either old or new version of this Leica Summicron 28mm lens. The price is about $1000 difference. Can anyone tell me if it is worth to buy the new version?

A: Excellent question. Here's my take I owned the most recent prior version of this lens (the version you're referring to as heavily discounted). I was always very satisfied with that lens. However, when this newest version was announced earlier this year, I took a flyer and sold that lens, anticipating eventually buying this new version. My motivation was based on Leica's statements that they had redesigned the optics for a flatter image more attuned to digital sensors. I own a first generation M Monochrom and recently wanted to do some landscape and ruins shooting, so I purchased this new version of the 28mm Summicron. I have not been disappointed and in fact I have been even more satisfied with this newest 28mm Summicron than the prior version, which as noted I felt was very good. I know this is much more info than you were looking for but when buying a $4K lens it's important to take lots of factors into consideration. The most important factor I think is will this new lens (or any lens) produce the kinds of images you want to take. I do a lot of landscape shots (and LOTS of trees) and the improvement in edge to edge sharpness from f2.8 on up was worth the expense to me. Even at f2, this lens is great but the difference between the two lenses is not particularly noticeable. By f4, watch out! Hope this helps.
