  • You can correct pretty much all these issues in software and it's not even noticeable.

  • The price is awesome.

  • It does not give "a 16-29mm equivalent range". That makes no sense. 16-29mm equivalent to what? Depth of field is not the same as a 16-29mm lens. A 16mm lens would have a different angle. How is...

  • These are valid concerns, but lets face it, not everyone is trying to be a professional photographer. I generally don't post high enough resolution versions of my images to where they could be used...

  • That being said in my example I mentioned the Canon 1DS, which by the way, at ISO 400 is *much, much* noisier than the Olympus E-M1 is at ISO 100.

  • I know you'll say, "But the ISO should be 400." Eeeerrrgh! Wrong. Because there is not a set difference in ISO between two cameras just because the sensor size is different. For one thing at 8x10"...

  • No, the idea of "equivalence" is a marketing ploy. Because worrying about how you can achieve the closest "equivalent" with one camera or another is not very useful considering that, really,...

  • DoF decreases slightly as resolution increases because you can see that some areas are out of focus, which appeared in focus at lower resolutions. That's a major reason why DoF equivalence is not a...

  • Easycass: The terms "crop-sensor" and "full-frame sensor" are bigoted terms that have been promulgated as an attempt to subliminally market more expensive, bulkier, heavier 135F gear to consumers...

  • Lets be honest about what this, in fact, is: a marketing ploy only. If the purpose of thinking about "equivalence" is to help you make a buying decision about what sort of camera to get, and all...

  • Simply put there is no way to create the exact same image on two different cameras with two different lenses, whether by following this article's conversion ratios or some other hair-brained...

  • Pixel density absolutely has to do with DoF. Depth of field is related to focus, which is related to the ability to distinguish points of detail in an image. If your sensor has only forty pixels,...

  • Commented on Nikon D810 Preview preview

    I'm not criticizing the D810, believe me. I think it's an awesome camera and the video quality is likely to be the best in its price range for that size of sensor. I would personally love to have...
