  1. Here is one I took with my A9, 100400GM and SEL20TC, also neither processing nor crop: BTW: tonight there will be a partial eclipse of the moon.Visibility info here, depending on cloud coverage.
  2. The latter. Updating on a Mac has always (at least since 2017) been a major PITA. Since I'm also on Apple hardware, I've resorted to doing it from within a Windows7 virtual machine, running inside of VMware Fusion software, with my MacBook as the host. If you have acces to a Windows system, that would definitely be the easier way to go, as you already found out yourself.
  3. If you want to overcome the limits of depth of view, you'll have to employ a technique called focus stacking. Basically taking a series of images from the same fixed position, with slight variations in the plane of best focus in between them. Then you will have to do some image processing, combining the areas of sharpness from each of the images, using specialized (and often proprietary) software. You may want to read this for more info.
  4. Just guessing: A gimbal and IBIS are two independent systems for image stabilization: while the gimbal tries to compensate for a change in orientation of the body itself (including the sensor as part of the body), an IBIS system merely shifts (and rotates) the sensor. Suppose, the body/sensor/lens unit experiences some sort of shake. If both systems (gimbal plus IBIS) were active at the same time, this would likely result in an overcompensation of the initial disturbance, since both systems don't know of each other and each "feels" to be fully responsible for the compensation. The best outcome would be for the system to take longer until stability is regained. The worst case would be an instable system where both mechanisms keep fighting indefinitely against each others corrections. In certain cases (body and lens from same supplier), two systems (OSS and IBIS) may actually complement each other's corrections, when body and lens are specified to be compatible with each other. In that case, the compensation work would be split between the two systems, with one system doing the shifting type of compensation and the other system taking care of the rotational compensation. There are six degrees of freedom, which might want to be compensated after all. I strongly doubt, that a Sony IBIS would be compatible with any non-Sony gimbal in that way. Suggested further reading.

    Same as with the butterfly pic.Besides, the depth of view does get quite shallow, at 800mm and close-range.

    Butterfly

    I had actually had set up my camera for birds of prey (in flight), that's why the speed setting was this high and that's also why the camera had to crank up the ISO this high. For a sitting butterfly, this is obviously way off the optimum.

  9. On a ten-day hike through the Swiss Jura I also only took the 24-105. Although at times I would have liked more "width" or more reach, I'm perfectly happy with the results. Below is basically the same target, shot at both ends of the zoom range: It's also pretty good at "macro" applications: From my album "Jurassic Hike"
  10. I would expect some very serious problems regarding your equilibrium and your orientation is space, when wearing a headset which only shows you what the camera is pointing at. Bumping into something would be one of my least concerns, stumbling off of a cliff or being run over by a car while your camera is looking the other way would be quite a different matter. In other words: I advise against even trying. Think of all those smombies, who keep their eyes glued to their smartphones and running into all kinds of problems, even fatal ones.
  11. Interesting subject! From what I gather from this article, lighting the object from the side seems to be one key ingredient.
  12. Is this a fake or a real question, first-time poster who didn't bother to introduce him/herself? Please be aware, that the sensor of the A68 is APS-C (only). The SAM 4.5-5.6 55-300mm is probably one of the worst-performing lenses for Sony A-mounts ever tested on dxomark, coming in at the 7913th rank of all lenses ever tested, in the "sharpness" category . This spells: Any lens will most likely do better in terms of sharpness. You don't need any particular advice here. Also, wide apertures don't go along well with sharpness requirements. Maybe you'll want to consider a used full-frame camera and suitable lense for you purpose. The dxomark's databases are a good starting point to read up on the matter. Also, tell us about the budget you're willing to dedicate to your quest. This will most likely considerably limit the range of your choices.
  13. You may want to experiment with setting ISO Auto range limits (MAX, MIN), as describe here: That seems like a compromise to me between setting a fixed ISO value in manual mode, and letting ISO "float" within a narrow range.
  14. @Iansky: I like the black&white version best. More drama. The billowing steam/smoke gives you a vivid impression on how "the west" probably got conquered. Btw: if you add a little comment yourself to the images in the gallery, that gives your viewers a chance to comment right on the spot. If you are not the owner, there is no way to start a comment on a gallery pic.
