There are several types of Leica 35 1 4 lenses

There are three types of M series in terms of optical design.

The first generation began production in 1961 and was produced until around 1989. The optical design has not changed much, and the best should be the later German version. The most collectible is the first generation of steel nozzle version. But the optical quality is not comparable to that of the contemporaries of summicron

The second version, the aspherical version, had two aspherical lenses, but was discontinued because Leica found that the bokeh imaging was defective after its release. Collectibles.

The third is the ASPH version, known as the "New Nine Jades". The apex of optical qualities. This year's latest version of the 35 simply changes the rear lens to a floating lens to improve the close-up capability.

There are 3 generations of the Summilux 35 in M-mount.

The first generation, which was produced in 1961, was available without glasses for the M2 and glasses for the M3. 7 tablets in 5 groups.

The first generation of ASPH. was produced in 1990, aspherical lenses were introduced. 9 tablets in 5 groups. The production is small, and the quality of the second-hand market is extremely high.

The second-generation ASPH. was produced in 1994 and is still in production today, one aspherical lens less than the previous generation, 9 elements in 5 groups.

R-port summilux 35 one, 10 tablets in 9 groups. Judging from the sample of foreign **, the effect of transferring to DSLR is very good.

I don't know how many models there are, but the Leica M3 can be paired with which, it doesn't matter.

The Leica 35 is a rangefinder lens, Canon does not have a 35 rangefinder design (Canon had a 35 rangefinder head in the 60s), and currently only has a 35 SLR design lens.

The biggest difference is bokeh and distortion.

The biggest difference between the rangefinder lens and the SLR lens is the flange distance, usually the flange distance of the rangefinder is about 1 2 of the SLR, which means that the lens adapted to the rangefinder camera can be closer to the focal plane, and the luminous flux can be greater (Volenda's 35 has done it, and most of the lenses of the rangefinder camera are symmetrical design, and the 35mm focal length is actually a small wide angle, and the advantage of the counter design is that the imaging distortion is very small or even zero distortion, while the lens of the SLR camera is mostly a reverse telescope design, which has a negative impact on the luminous flux, Distortion is not as well controlled as the sideshaft, which is an inherent limitation in the design structure. Therefore, the rangefinder lens has a natural advantage in distortion and out-of-focus, and the comparison of the same brand and the same period of the rangefinder and SLR lenses often wins in the out-of-focus (you can see the imaging comparison of the Zeiss ZM series rangefinder lenses and ZK ZE SLR lenses in production, which is clear at a glance).

The other difference is the style between the brands, Leica is naturally the color and imaging characteristics of Leica, and Canon is definitely Canon's color and style, which is the tonality of big brands and does not overlap with each other.

The Lycra is better in terms of clarity and resolution, and the Canon has the unique artistic effect of its own lens, depending on what you are after.

Of course, 5d3 should be chosen, and why?

1. Leica is a consumer-grade card machine, aside from **, it is equivalent to an ordinary card machine of Sony. What is 5d3? 5D3 is a full-frame professional DSLR.

2. Leica's non-replaceable lens, 5D3 has a strong red circle lens mass match. SLR, playing with the lens.

3. This Leica is actually very clearly positioned. It is a spare machine for photographers who have 5 brothers or even 1 brother to do specific things on some specific occasions and at specific times, which is what we often call Xiao Kuailing.

So? If it's your first computer, I don't recommend it, you're not suitable for it;

If you've been using 5D for years and feel the need to add a small and fast machine, then this Leica is for you.

The Leica is the god of the Beidou Taishan class in the camera.

Aristocracy in the camera.

The Queen of England used Leica.

**Expensive is related to rarity and positioning high-end brand effect.

As for how it works.

Holding the machine well will not produce good results.

There is only one possibility.

That is, there is a huge horizontal upside or you are not familiar with the machine.
