Canon Lenses Specifications
digital SLR sensor crop factor question?
Canon EOS 400D (Rebel XTi) has a 1.6x crop factor. kit lens is 18-55mm. my question: Is 18-55mm equivalent to 35 mm (18-55) X1.6 = 28.8-88mm equivalent to 35 mm. Also for the lenses in general, given the focal length equivalent specifications in 35 mm? The first question has two options. a simple "yes" did not answer my question
If somehow you can mount the kit lens (18-55mm) in a full frame 35mm camera (which is not possible for the EF-S), the focal length is 18-55mm. When you put the 18-55mm lens on a 400D. Have the same effect that an adaptation of 28-88mm lens on a full frame camera of 35 mm. All Canon EF and EF-S 35-mm focal length are classified using standard.

Nikon Vs Canon telephoto telephoto
The telephoto lens has been a great asset for photographers in recent years. In fact photography easier and more interesting. This can be attributed to how the target was built. The lens focal length photography is the star feature. The other is the optical center, which remains outside the building physics. Then there's viewpoint telephoto. This angle is the same as the one created by a lens focal length Regular even indicated. The arrangement is such, the objective is entirely in the focal plane and optical center.
The telephoto lens has always been a favorite of photographers since its launch. His ability to see distant objects has always tended photographers applause. This advantage has been identified by businesses in recent years with their own version of the telephoto lens. Two of them are Canon and Nikon, have launched the following Canon Nikon telephoto and telephoto. This is not a compromise blatant rip cheap modifications here and there, but in good faith with the objective their own strengths and advantages.
Canon telephoto Nikon Telephoto erase the need to approach the object. The same theme is to make them look closer to the photographer. It is a coincidence that the two sides. Both of them were made by their respective societies to pay attention to a particular detail of the object. The question can also be isolated from background embarrassing. This makes the precise details. That the Canon telephoto or telephoto Nikon, head and shoulders photos always come out well. There may be more accurate than through them.
These two objectives high shutter speed and film speed. Enlarge beautiful. Subsequently, the effect of camera shake is amplified if. Due these images at high shutter speeds that come through these lenses are clearly innate. These attributes may vary Nikon and Canon telephoto telephoto but the variations are too small and insignificant. Image stabilization also provides satisfactory. Openness is another feature provided by the telephoto Canon and Nikon and telephoto lens.
The above points have rarely faced these objectives against each other. Most important functions are them. There are slight variations that can be felt when the lenses are used to.

Need help finding my ideal digital SLR camera!?
I want a camera with the following specifications: – 6.10 Megapixel – High ISO, low noise – Image Stabilization – Live View LCD – High Dynamic Range – 3:02 aspect ratio – consistent with the objectives macro (preferably, but not required) – system for removing dust – 5-point autofocus – video capture – I have no Canon idea where to start looking for a camera that meets all these specifications, but if you could give me either a website that can help or a real camera, you know, it would be greatly appreciated!
Look here for the cameras with their specifications and see how they fit them. This http://www.dxomark.com/index.php/eng/DxOMark-Sensor depends on camera model (low noise = less expensive) – High ISO, low noise this depends on the purpose, all part of the lens design – image stabilization is not necessary if you use your SLR Digital as such. The attempt to hold a camera with two books with his arm outstretched just wondering blur caused by camera movement – As Live View LCD you can see this link, most devices are very similar in design – high dynamic range digital SLR Olympus All but 4/3rds and other devices have this aspect of the aspect ratio of 3:02-All systems are available DSLR macro lenses compatible with macro lenses (preferred but not required) DSLR dust have new ventilation systems Disposal fairly standard system, some systems have 51-point autofocus – autofocus system 5 Point Something is a remnant of P & S cameras (like live view) and is not necessary and difficult to use compared to actual capacity video camera Canon video is one of the two systems used by professionals – Canon This function has limited options for both, I am surprised we did not find the exact Canon is their responsibility.
