new article: Equivalent Focal-Length, Aperture and Speed of Camera Systems - Klaus - 08-22-2016 So I'm torturing you ONCE more ;-) http://www.opticallimits.com/Reviews/986-equivalence new article: Equivalent Focal-Length, Aperture and Speed of Camera Systems - dave9t5 - 08-23-2016 Thank you. Think this should be "50mm f/2.8" ? Micro-Four-Thirds Leica DG Summilux 25mm 1.4 "50mm f/2" new article: Equivalent Focal-Length, Aperture and Speed of Camera Systems - Klaus - 08-23-2016 Right. See .. even I got confused ;-) new article: Equivalent Focal-Length, Aperture and Speed of Camera Systems - borisbg - 08-23-2016 Klaus, thank you for taking the time to write it... you could have gone to take pictures instead. I am sure some of the PZ members will pull the calculators out (like revolvers in western). new article: Equivalent Focal-Length, Aperture and Speed of Camera Systems - stoppingdown - 08-23-2016 It's a topic in which I don't feel sure... ever. But for what I read, no revolver at my side. new article: Equivalent Focal-Length, Aperture and Speed of Camera Systems - Klaus - 08-23-2016 Sure, seeing is believing. I will add some pictures later on maybe. new article: Equivalent Focal-Length, Aperture and Speed of Camera Systems - Klaus - 08-23-2016 Quote:It's a topic in which I don't feel sure... ever. But for what I read, no revolver at my side. Math is on my side. Thus my ammunition is fairly powerful ;-) However, PERSONALLY I don't care too much about this topic. I have made my peace with small format systems long ago. When carrying beasts such as a Canon EF 11-24mm f/4 USM L or Sigma 150-600mm Sports for an hour, I just know that this just isn't the place to be for me. It's fun for that single hour but then it's enough really. new article: Equivalent Focal-Length, Aperture and Speed of Camera Systems - obican - 08-23-2016 Now let's carve all what you've written into a wooden club and bash people repeatedly with it everytime they say oh FF is much better Fuji is only APS-C Hasselblad will be great because it's medium format. Jokes Image noise aside (I wasn't even joking btw), do we have evidence that with larger photosites, does a better dynamic range and color information come too? Even though the lenses are slower? I will not take DXO as evidence btw so please nobody post links (A wooden club has multiple uses, mind you). new article: Equivalent Focal-Length, Aperture and Speed of Camera Systems - stoppingdown - 08-23-2016 Quote:Math is on my side. Thus my ammunition is fairly powerful ;-) True, but this topic manages in generating confused discussions in spite of that. I think that the problem isn't math and how it's understood, but the lack of clarity, in some discussions, about all the factors that play a role - mostly the fact that to achieve the same framing you have to either change the focal length or the focal distance. Quote:However, PERSONALLY I don't care too much about this topic. I have made my peace with small format systems long ago. With the partial exception of the 150-600mm ©, which anyway is a pain to carry on (yesterday I tried it with a 7km hike for the first time...), I agree. Nevertheless the argument is important because you're aware of the trade-off and you accept it. And since it's not only a matter of FF vs APS-C, since we are also offered with smaller sensors, knowing the thing makes one to precisely pick the trade-off which is fine for him. For instance, I accept the loss of DoF with APS-C, but not going further in that direction. new article: Equivalent Focal-Length, Aperture and Speed of Camera Systems - Brightcolours - 08-23-2016 A few notes:
