    Why not compare equivalent focal lengths? It seems odd to me to use the same physical focal length (35mm) and then crop the A7rIII result.
  • Replied in Not really
    I really only want to help inform people, and I'd encourage those with pixel-shift cameras to try it out, sure. The basic message is that any movement causes artifacts. Certainly one nice thing ...
  • Replied in Not really
    I don't think I was overstating anything--my qualifications for using pixel-shift were pretty clear and that cloning is an extra step for movement artifacts that occur. Maybe that's easy or not, ...
  • I agree, SFD is really more like an HDR+ mode. Auto bracketing and image averaging with one button. It does improve detail, and in my testing there are also huge gains in noise and dynamic range. ...
  • I for one would love to see recent smartphone comparison images on the studio tool. Smartphone cameras like on the Pixel 2 can be powerful photography tools, so it seems silly to ignore them as a...

  • Just to note, the DP Merrill cameras all have pretty different color renderings if that matters to you. See this link: ...

  • Replied in Merrill Clouds
    Merrill clouds might be the main reason I keep my DP3M :-)
  • I have an A7rII right now and have shot the DP2M, DP3M (currently own), DP2Q, and SD Q with 30/1.4. The A7rII sensor is pretty spectacular and out-resolves all of the Sigma cameras in my tests. On ...
  • Unfortunately, you have to use the electronic shutter with these adapters on the X1D, which can be a big problem when used indoors or with moving subjects. Nice idea, but pretty limiting.

  • Thanks! You can find more of my photography on my flickr: Here's the middle JPG straight out of camera:

  • I think pixel-shift is likely to be just as time-intensive to use as proper stitching technique, and probably even more so. With pixel-shift, you will have movement artifacts anywhere in the frame ...
  • I found this new blog post to be very informative about the L16: I think this type of camera has a ...
  • Fun comparison, thanks! I agree, I love sunstars and the DP3M with its 7 straight blades makes beautiful sharp 14-point stars and they are well defined at quite wide apertures. Here's one example ...
  • Replied in Light L16
    Looks like some impressive improvements. I was really intrigued by the previous post comparing the L16 to a Canon 5D IV and Fuji XT2: This ...
