2010年4月18日 · <p>I'm confused, I'm reading about crop factor and the difference between a full frame sensor and APS - C sensor. Does a CMOS sensor have any relation to APS - C sensor? <br> I presume the APS - C sensor pertains to the Lens and APS - C sensor pertains to pixels.<br> I'm trying to understand the technical aspect of photography</p>

2011年12月10日 · (but my sensor "sees" like it's an 1,120mm!)</p> <p>To be sure, there are many reasons besides sensor size to buy full-frame sensor cameras. They often are the flagships of their line, and as such, get the more advanced features long before they filter down to the cheaper cameras.</p> <p>The bottom line is, both sensor sizes can take great photos.

2003年12月20日 · lifespan of the digital Sensor or CMOS in the case of the Canon . 300D? Do these sensors ever wear out or rendered ineffective after . so many shots. I have shot 1400 pictures in less than two months. I have printed only 50 or so. Most of my shooting has been geared . to learning photography and its techniques. Thank you in advance for all replies.

2011年12月10日 · <p>CMOS is a sensor type not a size/format. Your 400D has a "crop factor" of 1.6X as compared to a full frame sensor. For example, a 50mm lens on a 400D will give you the same field of view as an 80mm (50mm x 1.6) lens on full frame camera.</p>

2004年10月13日 · Some alternative explanations for instances of apparent sensor damage may be that anti-reflective coatings on the near-IR exclusion filter were burned (or perhaps a plastic IR exclusion filter was melted); that the glue that is found in some CCD and CMOS packages was melted; that other electronics near the sensor were destroyed through ...

2007年3月15日 · The Super CCD has a bit more of pixel per pixel definition than 10MP CCD/CMOS (just like the old nikon 6,1MP sensor had a bit more pixel per pixel definition . than the new 10MP sensor) But have to be downsampled a bit to get the same very . sharp result of the Foveon. This one has the best dynamic range, this is

2006年9月28日 · digital sensor. I recently had my first fried sensor... it worked fine one moment and the . next -- just signal noise on screen. The official manufacturer verdict is the sensor is . unrecoverable and in need of replacement.</p> <p>I notice it's difficult to find published MTBF rates for sensors. Although it is possible

2009年9月6日 · <p>Sensor damage is possible but unlikely since most sensors have overload protection. The roundish gray spots could be lens flare from the sun outside the field of view. You could take some shots against a blank white wall to see if the artifacts are still there. Another possibility is there is dust on the sensor or on the back of the lens.

2014年12月24日 · Some lenses employ a circular gradient filter to overcome vignetting, which would apply to camera movements too. Some cameras, such as digital Leica cameras, make a correction in firmware based on a table of lense characteristics. There's no reason a MF digital back, particularly a CMOS sensor, could not do the same.

2016年3月23日 · <p>From my understanding "light" and "light, while under power" make a difference.<br> To spot dust on a sensor: take pictures at f 16 (or smaller) and check if different ones reveal dust i.e. black spots) in the same place.
