  • I find it's best to think in terms of an acceptable circle of confusion and go from there. I use these apps, which also include diffraction in the calculation: http://www.georgedouvos.com/
  • Hi Manzur, All I can think of is that the tolerances on the body and/or the adapter cause the release pin on the body to jam in the little slot in the adapter. So pushing the lens release button ...
  • Hi Manzur, This is the first I've heard of an early batch with lens release issues. I've had no problem with releasing the lenses so far, just the Steelsring. I purchased my GFX 50S in October ...
  • Hi Phil, The Steelsring GFX-EF adapter I have (others may be different) assembles tightly to the GFX – tighter than the GF lenses. But that alone wouldn't have been enough to 'lock' the adapter so ...
  • I have a Steelsring EF adapter and used it on my GFX 50S with some of my Canon L lenses and a Sigma. Mixed results. The adapter hasn't been reliable. Sometimes it'll enable focus, sometimes not. ...
  • I was hoping for a T/S announcement with the GFX 100 but it didn't happen. We didn't even get an updated lens roadmap. I think Fuji is missing a significant* market here, especially now with the ...
  • I expect they are currently deciding which 3 (three) T/S lenses to show on the map! OK, I can dream. But maybe just one. Please?
  • The GFX 50S strap lugs were a major discussion point when the camera was introduced. You might want to search for comments. The metal clips click into place over the lugs and aren’t easily ...
  • Replied in Stepping down
    Jim, I have been a member of this forum for the past 18 months or so, since purchasing a GFX 50S. The forum has been an invaluable resource, both before and since the purchase, and specifically ...
  • Replied in Fuji GFX 50r
    Average or minimum? Link should be: https://blog.kasson.com/the-last-word/fujifilm-profiles-for-the-gfx-50s/
  • Replied in Results
    Thanks for the comparisons. If I hadn't used TrueDOF-Pro I think my gut would have been close to Erik's. But some choices were made on what objects to include in the "best sharpness" DOF – like ...
  • Replied in A game
    May I use TrueDOF-Pro? If so, I'd choose as follows: It will be interesting to compare the George Douvos app results to the Jim Kasson app results. Speaking of which, TrueDOF-Pro only provides for ...
  • Jim, George Douvos' approach is also interesting – provides a bit more control than a regular DOF app. Uses formats but not pixel pitch: http://www.georgedouvos.com/truedof-pro-overview.html He's ...
  • Two things of note: 1. The photographer has a slight smile on his face. 2. The 100S vertical grip still looks more like a display stand than a grippy grip.
  • The lens was also reviewed here: https://jonasraskphotography.com/2018/11/30/mitakon-65mm-f-1-4-for-gfx-review/
  • Replied in Obsolescence
    I used to have a 540i with six speed manual transmission, because I was trying to get maximum enjoyment in a luxury 4-seater. Turns out the synchromesh couldn’t be rushed and the steering required ...
  • Not sure what the parallel for rubber is in the camera world, but I can relate to the chunking problem. I’ve been involved in track testing street cars for one of the major brands, usually ...
  • I think those are good examples – but why don’t we see more of them? I like the idea of more practical system-level comparisons. With image quality getting so good, and a wide range of cameras able ...
  • See this: https://www.dpreview.com/forums/post/62287380
  • There's more layering with the American flag over the face, and possibly another view further out past the woman in the train. Then there's the connection between the phone in the Believe in the ...
