Canon Lenses What Does Usm Mean
Question about Canon lenses, please help?
I'm using EOS 450D, and I want to achieve a career goal for clear, professional photos. I to the store today, but the lady was not helpful enough, they used their EF 200 mm f 2.8 L USM II, told me that is a fixed lens, but what exactly is a fixed lens? I know this is the most professional but she told me that if you are taking photographs of people who should buy the EF 24-70 mm f 2.8 USM. I love the photos I took with the EF 200 mm f 2.8 L USM II, but does that mean you do not get great pictures of people? Why would not be able to take pictures of people with the target? I there was a zoom because I could zoom the picture: / I'm sorry if I'm understanding right, I'm new to this but very interested to know … I think they mainly use to take portraits of people …
When she says "fixed lens" which means it is not a zoom lens, but instead a focal length lens fixed – just an opinion and have to change positions to get a different view (instead of zoom). The 200mm f/2.8 is an excellent lens for portraits and you get great photos. However, in a smaller area of a small room, could not be able to take a step back far enough to get certain types of pictures, full-length portraits or group photos. Therefore, it is recommended to look for 24-70mm, which has a broader view and can be seen (as not have to take a step back or step closer). If you really like the 200 mm f/2.8, and have thought about how you would use it, then it is a great option. But if you have not thought about how you use it, or how often you would use it, take a moment to consider what type of photos you want to achieve, the types of places you are taking pictures, and when / where you would be using the lens. This will help you decide which lens is best for you. EDIT: You are confusing the zoom approach, apparently. A fixed focal length lens has only one point of view, and to change the point of view, you have to physically move closer or back physically. But with a goal 200mm, your opinion is very narrow, so it might not be able to take a step back far enough if you want a shot in general.

Where to purchase, I've never understood the f/1.4 f/1.8 and it is better and why and what they mean numbers and meanings as the Canon 50mm 1.8 and the difference between the Canon USM 1.4 and 1.4 are 50 mm, but what these numbers mean? USM and the AF-S, all these letters that came after the lentils?
The f / number is the aperture or lens opening. When you see one called f/1.8 lens or do you mean maximum aperture f/1.4. The higher the number the more light the lens can potentially leave the unit photo. A lens with a maximum aperture of f/1.4 can let in more light than a lens with a maximum aperture of f/1.8 or more. This does not mean necessarily a better lens, even necessary, for his style of photography. Lenses with maximum apertures are usually really cool expensive due to the increase in focal length, glass lenses must grow larger diameter to allow light to pass. For example, a 50mm lens with a maximum aperture of f/1.8 lenses have very small glass. However, a lens of 400 mm with a maximum aperture of f/1.8 lens should have a great lens for the opening wide enough to get the same amount of light to travel the length of the target much more than the much shorter 50-mm lens. Therefore Opening up the big lenses get really expensive as the focal increase. Many people do not know what they're talking to assume that higher prices for a glass means it is a better objective. But this is not true. The truth is that the major objectives to open max require glass lenses, which are expensive to make. Also, if you do not understand the concept of basic SLR opening, you really need to buy a good book or two on SLR photography and read it. If you do not understand the relationship between shutter speed, ISO, and open, then you will not maximize the use of an SLR and could be using a point and shoot camera. I recommend a book entitled "Understanding Exposure. "It is considered one of the best books to learn about how to effectively use a SLR.
