Crop factor explained at its best. Thank you
I didn't like the crop factor explanation too much. Sorry! Needs more illustrations, I think.
BTW, I already know what crop factor is. but if I didn't, I would feel this article is incomplete.
CROP FACTOR
Techniques Glossary CROP FACTOR
Describes how much an imaging sensor has been cropped in relation to its full-frame equivalent. It always describes how many times larger the full-frame is in relation to the cropped sensor.
Just remember the crop factor in your lens buying adventure. A wide-angle lens will behave like a normal lens when used on a camera with crop factor.
The crop factor would mean that the digital image would be more tightly cropped. If we change lenses to compensate, we also change focal length, on which the rule of thumb depends.
CROP FACTOR SENSORS AND LENS PERFORMANCE
The crop factor, FOV and perspective rules follow each camera through it's entire range of photographic capabilities from wide angle to telephoto. If you want the equivalent of 24mm on a 1.
Crop Factor
(also:
Focal Length Multiplier
35mm Equivalent)
Not to be confused with "Crop" of a picture, these terms are exclusively used in the context of relating focal length to field of view (FOV), ...
The crop factor isn't a major issue for most users, but it does have important consequences for some.
While the crop factor of APS-C cameras effectively narrows the angle of view of long-focus (telephoto) lenses, making it easier to take close-up images of distant objects, wide-angle lenses suffer a reduction in their angle of view by the same factor.
6X Crop Factor
The one thing that sold me on the D700 was the fact that its full-frame sensor made it 2EV(Exposure Values) faster than my D300 and that's something very important when you shoot with natural light in very low-light situation as I do a ...
Understanding the crop factor.
Imagine putting the same focal-length lens on eight different kinds of cameras. Position each camera in the exact same place, at the same height, aimed at exactly the same spot.
24 megapixel APS CMOS sensor, same crop factor as NIkon D300s / Nikon D7000; 6000 pixels x 4000 pixels. This is a lot of megapixels, and it is not clear if most users will need this many megapixels.
Focal Length Multiplier and Crop Factor
Whether a camera lens is seen as wide-angle or tele is dependent on its Angle of View (AoV); for a particular image size AoV is dependent on focal length.
Lepp does not understand what the crop factor is. Since the sensor of an APS-C camera is 23 x 15 mm in size, ...
Geeky aside - camera body crop factors
The landscape shots above were taken with a Canon 30D digital SLR with an APS-C image sensor about 22mm wide.
03 if it's a DSLR crop factor of 1.6 then the CoC should be 0.02. Therefore DSLR full frame / film at a focal length of 24 at f13 the hfd should be around 1.75 meters. A DSLR crop factor of 1.6 should be around 2.6 meters.
On a digital camera that has a crop factor, a fast 50mm lens will often perform quite nicely in basketball from courtside and a fast 200mm is ideal from the stands.
In DSLR cameras it is important to know about the crop factor. Since the sensor in the cameras is smaller than a 35 mm film frame you need to consider the crop factor. In cameras using the APS-C sensor this factor is 1.5x or 1.6x.
6 crop factor is actually an effective 640mm lens. Just remember, air shows are usually several hours in duration, and longer lenses can get quite heavy.
Also know as crop factor. It affects the range of the lens by effectively "magnifying" the image making zoom lenses seem to have a greater range and reducing the angle of view on wide angle lenses. Most modern DSLR have a 1.6 crop factor.
CONCLUSION: if we want to compare cameras with different sensor sizes (crop factor C) but with lenses to obtain an equivalent Field of View, it is not sufficient to use the equivalent focal length (f2=f1/C), ...
However, the small sensors are a minus (1.3x crop factor). That's why I turned to the Nikon D700. Though smaller in size, the D700 is quite aggressive and produces relatively cleaner photographs at ISO 4000.
We've already talked about the low noise & wide-angle capability of the D3, but it can also shoot in DX mode (with or without a DX lens) to provide that sometimes helpful "crop factor". But what is the image quality like?
For my Canon EOS 350D with its crop factor of 1.6x, the 10-20mm gives an effective focal length of 16-32mm.
6x crop factor (ie: a smaller than full frame sensor) then you would not get the same view of the scene - you'd get less. The view you would see on your 1.
for 35mm film photography, before VR technology- says that one can shoot, safely, with shutter speeds around the reciprocal of the focal length of the lens mounted; for 50mm, 1/50 sec; 105mm at 1/125 sec; etc. For digital photography the crop factor ...
Focal Length Multiplier For a D-SLR that uses an imaging sensor smaller than 35mm film frame, the ratio of the diagonal of the camera's imaging sensor in comparison to the diagonal of a 35mm frame is the crop factor.
There's a heavy crop factor too which is one reason to frame your subject with the LCD monitor on these models whenever practical. The EVF's on the other hand generally show all the information that is normally visible on the camera's monitor.
