  • For a given framing: Same dof for same f-number whatever the focal length The background blur depends on the opening diameter (the ratio focal/f-number) Thus a 100mm f2.8 lens will give the same ...
  • Replied in same dof
    I would not say so. For the same framing, you have the same dof but more background blur for close subjects. For far subjects, the dof is shallower with long focal lens. For a given framing, the ...
  • High Iso performance has nothing or little to do with pixel size but rather sensor size. This is the total light hitting the sensor which is important, so a bigger sensor will collect more light ...
  • I agree that this is only true when dof is an issue. What I really miss in the new cameras is the "old" panorama function which helps shooting hand held panos... Now we just have the sweeping pano ...
  • Hi, Nice results ! Though, sooner or later, this technic will be useless because diffraction forces the same limitation on both pictures... With the long focal, you have to stop down for equal dof ...
  • I fully agree with you, no need to lock exposure contrary to what is usually said. Though, not sure softwares behave as expected. I had a real doubt with Hugin because it said it could stitch ...
  • Replied in Fuji 's fault
    Thanks, I was very lazy I admit.... Maybe they wanted to force to use their flash system (but we are still waiting...). Anyway, they should provide a FW update for this, it is not normal that Fuji ...
  • Replied in Fuji 's fault
    You can go to the nissin i40 site and have a look at the asterix (2 for Fuji !).... It could be fixed by Fuji but Fuji did nothing so far....
  • Replied in Upgrade to fx?
    Not worth... Looking at dxomarks, it is really behind current FF annd I would even say the D7000 is preferable.
  • Due to diffraction. Diffraction affects all lenses identically, expensive or not No. Maybe FX lens because diffraction is less visible at f16. But it has shallower dof so in fact there is no real ...
  • Equivalence answers to all these questions, doesn't it ? So I don't understand the interest of this post, unless you did not understand equivalence. Total light hitting the sensor is what matters, ...
  • Replied in Fuji 's fault
    There are limitations with the nissin i40 and this is clearly Fuji's fault because they did not fix this in a firmware update. With other camera makers, these limitations do not exist. There is a ...
  • An airy disk diamètre can have 2-3 pixels before diffraction limits resolution (see cambridgeiincolor article about diffraction). Furthermore, the sensor must have more resolution because of the ...
  • Your opinion... 100% disagree. You can sell a camera if it has high rates in the reviews. Agree that going beyond the diffraction limit would be nonsense.
  • They are improving resolution as well as the Iso performance . The problem in your post is that you consider as a prooven fact that a smaller megapixel count would make better Iso performance. ...
  • Replied in f0.5 limitation
    Without context, this is true. For a given lens, a larger sensor collects more light..The fov is not the same (we could say that it "collects" more fov) but the sentence is true. Secondly, you omit ...
  • Maybe it is time to grow up, don't you think so ? This kind of illustration has nothing to do in this forum, we can respect each other. I am not sure the term hilarious you use as welle as the ...
  • 100% agree !  This is what I said,  raw converters try to minimize this issue. To have a fair comparison,  you have to sharpen a bit with adobe. This is really difficult to compare raw converters ...
  • Not well but better I would say. The issue still remains. You can often reduce a problem with pp but then you introduce other problems. Nothing is free. So in your opinion the x-trans is perfect ...
  • Good to know you see no issue in the mushy foliage that we see in the posted pictures pp with rawtherapee ! You have an extreme position in the sense that you want the x-trans to have ONLY ...
