  • Replied in Sounds familiar
    This happened to me with the XF27mm about two years ago. Same on-screen message, and the issue was with the lens. Tested with other camera-lens combinations to verify that it was a lens issue, ...
  • The autofocus on that one can be a challenge for weddings, though. At least for the slower focusing lenses such as the 80mm 1.7.
  • I guess the 120mm macro in this case is a Tesla Cybertruck, or top line Range Rover or something. I haven't looked at direct comparisons with other formats macro, but my impression is that for ...
  • Putting a macro tube on the 110mm is like getting a trailer attachment for your Bentley to move furniture. Sure it can pull it, but why are you using a Bentley for that when a Toyota will do the ...
  • Replied in IBIS and energy
    IBIS takes energy to operate because it performs work (force*distance) on the sensor package relative to the camera body's frame of reference. Physics 101: Energy used in a reference frame = Work ...
  • No doubt IBIS is a major feature. The battery argument is invalid; just turn it off and you have a non-IBIS camera. They proved with X-S10 that they can make it small enough as well. However, the ...
  • I've been looking at it as well, and I think there is ~3 parts to this. 1) There is indeed more to lens design, especially at such wide angles. The 14mm 2.8 has a certain quality that strikes me ...
  • Umm, no. That would be true if the 14mm had to cover the same size sensor - because then it'd have a wider field of view than a 20mm and need to control light coming in at those wider angles. ...
  • Replied in Test
    If you have it, you can test it and in three hours you'll know. Maybe or maybe not you'll get the answer here in around the same time. Please do report what you find if you're able to test it; I ...
  • I haven't seen any. Bumping for interest.
  • Intel has their hands tied behind their backs with internal problems, being stuck on their 10nm node and frequent leaks of bad management and unhappy workforce. Looking at benchmark comparisons: ht ...
  • It looks impressive compared to Intel, but that's partly because Intel has been stagnant for the last decade.
  • OK I collected my thoughts now, so here goes; First of all, light gathering happens before iso/gain is applied, and is not exposure. It's a part of the recipe to create exposure, just like flour is ...
  • Replied in Confused myself
    I started to write a response to this, but after editing and rewriting three times I just ended up confusing myself. :-|
  • The lenses are the resolution bottlenecks in the corners at most apertures while in the center you can clearly see separate pixels, indicating that they could resolve much higher pixel densities ...
  • Replied in Air is a sponge
    When it gets cold it can't hold as much water, and the excess is pressed ('condensed') out of the air sponge. When it gets warmer it can hold more, and absorbs water back into itself, from mist ...
  • Replied in curves
    They're both regular and familiar shapes that we see all around us, so I doubt I'm the only one not having a greater problem predicting where a curved plane will be as soon as I'm familiar with ...
  • Assuming they release with good autofocus performance, does anyone know the Nikon lens catalogue well enough to say which might be particularly interesting for Fujifilm APS-C? Telephoto primes come ...
  • Replied in curves
    I still don't see how this is a negative in general. Sometimes I'd prefer my plane of focus to be flat and angled to the left or right, sometimes I'd prefer it to be curved away from me, sometimes ...
  • Honestly the uncertainty of WR makes me want a Pentax. But the rational side of me knows that nothing is certain, any body can have a fault or get a compromised seal over time, so I wouldn't go ...
