  • Zero, as it was on the K100D right away. I find it highly useful for checking the camera's basic functions (especially battery life and remaining exposures) when switching on the camera when it's ...
  • You are correct in that the K-bayonet was designed for film/full frame, and that with a CMOS/CCD it is more logic to use an EVF than stay to the mirror. Still I don't feel I am missing anything ...
  • I think it's best to assuming you got good copies to start with. If you get unexpected bad results you may start doubting. Open aperture is most critical, so if these are really too bad you may ...
  • If you are on a budget of $100 or so: a used K100D (super is better) may be obtained at the price level of your old-era objectives, and there is nothing wrong with it if you are happy with 6 MP ...
  • 'daylight' is a broad term, and its color temperature varies with the time of the day, in the sun, in the shadow, when clousy, etc. I would say AWB is safer, but may go wrong occasionally as well.
  • Although I cannot see the full resolution it all looks rather sharp corner-to-corner and I don't see any CA, or does the camera correct for that ?
  • Replied in Acropolis
    It is also impressive for a typical viewer. As others indicate: the 'focus' fo this picture is twofold. Did you also go down the stairs somewhat and direct the camera more skywards ? Then you ...
  • don't. If it has a M42 screw you can buy an adapter to K-mount, that might be more expensive than the lens. You will have to use it fully manual, which is not easy or convenient for a zoom lens. ...
  • I made some 15k pictures with the (older) Sigma as standard lens, no real complaints, except for 17 mm/2.8. So you better forget about 2.8 and an advantage in that. With the Sigma you can get ...
  • compare to the (older) Sigma 17-70 2.8-4.5 17 mm - 22 mm = F2.8 23 mm - 34 mm = F3.5 35 mm - 64 mm = F4.0 65 mm - 70 mm = F4.5 roughly half a stop difference
  • Could you tell us how the maximum f-stop changes with the focal length ? It is 3.5 at 16 mm, 5.6 at 85 mm, but what is it e.g. 24, 45, 70 mm ? You can see it in the camera indication, assuming that ...
  • Maybe, but I would think the angular distance between stars is constant, and lens distortion will be minimal, and not relevant if the stars do not move over the sensor. Maybe the O-GPS unit only ...
  • Replied in DA16-85
    For comparison with Sigma: 85mm/5.6 means 15.2 mm lens diameter. 70/4 means 17.5 mm lens diameter, and for the older version 70/4.5 means 15.6 mm lens diameter. So the difference at 70 mm might be ...
  • Replied in DA16-85
    I'm also curious. Online I only find it for pre-order, so probably nobody has one yet.
  • Ok, now it is clear, thank you. Maybe it is also interesting for the other readers to mention your exposure time, whether you used O-GPS1 (I understand so from the Bulgarian text), ISO setting. ...
  • Good catch, congratulations. Did it go left-right or right-left ? I thought I had caught a few, but at closer examination they were satellites, such as in your 2nd picture. Still I caught one once, ...
  • Very nice, but I would expect star trails at 30 seconds exposure. And it's many stars for 3 seconds, or did you use some trick (stitch images, use tracker) ? How did you focus ?
  • Same comment from here: nowhere it becomes clear that you offer photographic services and what they are. Some pictures at the opening page are overprocessed, others not. For the time-lapse movies: ...
  • I can understand the auto-wb was off, but then still it should be possible to set a reasonable WB during post-processing the RAW-file. Like others said: if you look critical, the illumination is ...
  • Looks perfect, good central sharpness, nice bokeh, no purple fringing. What aperture did you use ?
