  • Are you saying, f2.8, 1/50 sec, ISO 100 gives the same exposure as f4, 1/50, ISO 200 at the same focal length? What do you mean no film, no exposure? Exposure has not thing to do with film or ...
  • I do not have specific test to tell but I do not  do focus and recompose technique unless the object is not on grid. Even in that case, I try the closet point and recompose. Which means, I hardly ...
  • I am curious why do you think this is a bokeh test.  Is it because the the DoF from the focus point in the center will not cover the branches a the edge?   If that is the case, it would be good to ...
  • Replied in Sony colors
    I am not sure you meant which one makes it worse. More signal on the sensor should mean less noise in the image overall. I do not think ISO directly indicates exposure. I could not find the ...
  • Replied in Sony colors
    Why doesn't increasing light onto the sensor produce less noise in the image (unless specially look at the shadow or dark area)?  In addition, should this be compared at the same out put size ...
  • The effect that most photographers experience of increasing ISO in this case will appear to increasing noise as stated.  But that does not mean that the pointed definition is wrong. It still holds ...
  • Ah, that is a good point. It is an interesting area in Canon's system. Canon currently do excellent job in this line of lenses so far. I still do think on the luxurious line, Sigma is stepping up ...
  • I have read some reviews about this trigger. A few things stand out for me about the trigger. - One mentioned the lock mechanism to the flash show is too small and the reviewer mentioned he needed ...
  • Sigma appears to have found their success formula lately. If they can capitalize this quickly (I do not know how hard or they even have capacity to ramp up new lines of lenses) then they can take ...
  • Doesn't IS or a tripod allow slower shutter speeds to gather more light without causing motion blur due to unsteady hand as well? The F2.8 gives more light but at the expense of DoF trade off?
  • Replied in +1
    Yes, for all of the above.
  • I do not think that what the previous answer was trying to say. The following is an excerpt from the http://www.josephjamesphotography.com/equivalence/#equivalentsettings that I think explains ...
  • For the second point, the f2.8 will also have more shallow DoF than at F4 at the same time (assume else is the same).  If that can be tolerated (i.e. it is not contracting to the first point) then ...
  • Replied in 50 1.2 L II ?
    I can't tell for sure. But I think it is real. It should not be an easy mistake and left in the video in my opinion.
  • A good question.  I would like to know this too. I can understand development priority for PD over CD in the early models but I am not sure that should be an excuse for the later model. This is ...
  • Yes, perhaps you are looking for something that pushes you to the next level and you have not found that yet.  All of the sudden, everything is less satisfaction to you. I agreed with those two ...
  • I am not sure that this will help you or not but I actually like your style. Those pictures are good in my opinion and I would say they are better than mine :-) Perhaps, you are going through ...
  • Replied in I'm in.
    I have been waiting to hear 24mm / 1.4 Art. When?
  • Replied in 24mm Prime
    These are good prime lenses or certain but to really makes a good match with EOS-M then I think it should be EF-M class of lenses.  The EF-M 15mm F1.4 would be nice.
  • Replied in M2 assessment
    +1. I am not sure this is possible with EF-M lenses or not but it would be nice to have an ability to do manual focus on the camera body (via one of the dials) instead of on the lens's. It is ...
