There are two types of Sigma 15-6mm lenses. What is the difference between the C version and the S version, and the price difference is so big?

Sigma 15-6C version or S version, which is more suitable for shooting scenery?

Sigma's telephoto 15-6 lens has two versions, one is version C and the other is version S ..

version c is aimed at ordinary users, and the lens is slightly lighter. The lens structure and workmanship are different from those of the professional version, and the price is cheaper.

S version is aimed at users with fever level, and is more inclined to be used by professional photographers. The lenses and workmanship are more professional, and the weight of the lenses is a little bigger and the price is higher.

In fact, these two shots are made for shooting birds.

is a good partner for shooting ecological and sports subjects.

Of course, telephoto lenses can also be used to shoot scenery. We often use telephoto lenses to shoot the levels of distant mountains and the details of buildings, which is also a good choice.

Of course, Sima's telephoto 15-6 can also be used to shoot scenery, but personally, if only from the perspective of shooting scenery, there is really little difference between them, at least we ordinary people can't see much difference with the naked eye.

as we all know, in general, the scenery is shot with a small aperture, but in the case of shooting with a small aperture, they are really the same. I remember when I was just playing photography, a friend who opened a photo studio said that the dog's head was also a bull's head under a small aperture. I remember that when he was shooting in the shed, 18-55 shots were his usual shot.

So, there is indeed a big gap between the two shots of Sima in shooting other aspects, but I feel that if they are only different in scenery, they are almost the same.

that's my opinion, and you are welcome to add or comment.

there is a big gap in lens positioning, lens workmanship, lens price and imaging quality.

first of all, the difference between the C version and the S version is determined by the different positioning of the lens. The 15-6C version is positioned for ordinary photographers, which is biased towards the portability of the lens. The lens and mirror body of the lens lens group are mainly lightweight, and there are few lens groups, so the mirror body work is also suitable for general environments. The 15-6S version (Sport) is aimed at professional photographers, and it is biased towards the firmness and durability of the lens. There are many lens groups, and the structure of the lens body is also splash-proof, which is resistant to the harsh environment in the field and the weight is relatively increased.

the lens structure of the p>15-6C version is 14 groups with 2 lenses, and the lens weight is 193g. The lens structure of the 15-6S version is 16 groups with 24 lenses, and the lens weight is 286g. Generally speaking, the increase of lenses in the lens group means the improvement of imaging, and the extra lenses of the 15-6S version are mostly used to make up for dispersion distortion caused by telephoto shooting, etc. After all, the S version.

From the price point of view, we can also see the difference between the two lenses. The 15-6C version is about 8, while the S version is about 1.7W, with a difference of nearly 1W, depending on your budget.

Although there is a gap in imaging, my personal opinion is not worth the difference of nearly 1W yuan. The S version of the high-precision mirror body structure and the so-called "professional" lens name both account for a lot of money. If you don't often go to the wild in such harsh environment, the 15-6C version is enough, light and cost-effective. If you are a professional photographer, then the S version is a good choice.
