I'm a novice. What's the problem with the Canon 7D lens?

It only started for 7 days this year. This machine has a very high cost performance. I will answer your questions separately.

1. In non-Quan Huafu SLR, 7D is considered high-end. This machine is great for beginners. Don't worry about stopping production or new models. Because beginners start with cameras, it is important to learn skills and accumulate experience, and equipment is secondary. Besides, 7D is already high-end for beginners.

I bought the lens of 15-85. Because 7D is an APS-C frame, multiplied by the focal length factor of 1.6, the focal length of this lens is 24- 136. The lens with this focal length can shoot a wide angle, so the effect of shooting scenery is much more realistic than the dog head of 18-200. Resulting in image quality degradation. Although it is known as the best in the world, if you want to study photography in depth, it is still recommended not to start. 15-85, you can also shoot at a macro, but the effect is not as good as that of a professional macro lens. I suggest you familiarize yourself with the basic knowledge of photography before developing into macro lens. A good macro lens is still not cheap.

3. I also bought two heads, and the other one is dedicated to portrait shooting, 50mm 1.4. The kind of person you want is clear and the background is vague. This head is definitely enough. Of course, if you want something cheaper, the cost performance of 50mm 1.8 is also very good.

I don't know much about other brands of lenses, but if the economy allows, I should still use original lenses.

Invincible rabbit is the nickname of 5D II, the machine of Quan Huafu. There is no point in copying and pasting. If you want to know about Quan Huafu and non-Quan Huafu, you can go to Baidu Encyclopedia. If you don't understand, you can ask me at any time. Invincible rabbit's light fuselage 15600, don't consider it.

About the last person you mentioned, the background is blurred, which involves the concept of depth of field. Small depth of field can also get the desired effect. What affects the depth of field? A. lens aperture: the larger the aperture, the smaller the depth of field; The smaller the aperture, the greater the depth of field. B. lens focal length: the longer the lens focal length, the smaller the depth of field; The shorter the focal length, the greater the depth of field; C. shooting distance: the farther the distance, the greater the depth of field; The closer the distance, the smaller the depth of field.

PS。 If you are interested in photography, you can buy a DSLR digital SLR Bible. This book is not bad for the introductory stage.

Finally, I wish you good luck in filming ~
