  • DA* 300 f4 is good opticaly, but has micro SDM AF motor, pretty slow, no match for Nikkor AF-S In the light of the coming Pentax FF, we expect new lenses, with ring DC motor. Beyound some ...
  • F and FA 50 f 1.7 are very-very good opticaly, maybe less so the hexagons of the 6 aperture blades... F has noisy AF, if not close prefocused, but is decent fast AF wise, and look better build. FA ...
  • Flare resistance on all CaNikon 70-200 f 2.8 and f4 variants, in practice, is more like non-existent.
  • Contax AX, 1996, autofocus with moving film plane (Kyocera tech.)
  • Using this formula, FA 24-90 f 3.5-4.5 is only 64.6 mm tele, when focused at 0.5m. Lucky that for human portret, perspective distortion limit the focusing distance at ~ 1.5m, where is close to 90mm. ...
  • DA 16-45 f 4 help a bit. Some lenses show exaggerated contrast, and tend to darken the shadows way mare. DA 18-55 II ( all variants normal/WR/DA-L) are like that, way to contrasty, unnatural. FA ...
  • I have this lens, and I don't like it, because: - cold rendering, which combined with high contrast, renders very dark unnatural shadows, covering details. - is wobbly and plastiky, - not very fast AF,
  • What is si special and unparalleled ???

    OK 105 micronikkor cost more new, but has AF, and even a fast one...
    SH is more afordable, and againn pretty good AF...

    Sigma 105 cost a little...

  • Replied in what?
    You're absolutely right, is just a snapshot, and is not worthy of a true photography contest, but that doesn't change the fact that looks better then most of the other entries, except the one who ...
  • You should be glad, that your work is not mixed with all ordinary kitsch. Comparing them with your photo, all the others entries look plain stupid.
  • I see with the naked eye, dots at 1200 DPI, and I find wet 2400 DPI free of dots to the naked eye. 720 true DPI (no dithering), is a standard (Epson), and with dithering is upsampled up to 5760 DPI. ...
  • A4 @ 720 DPI = 50 MP - so-so checked, but 44x33 is not 2/3... A3 @ 720 DPI = 100 MP A2 @ 720 DPI = 200 MP A1 @ 720 DPI = 400 MP A0 @ 720 DPI = 800 MP etc...
  • You need both. You can take 645Z first, because is already available. Only downside I see, is that D-FA 645 115 mm f2.8 is missing...(or the FF645D camera...because FA 645 150 f 2.8 is dedicated ...
  • Replied in Serious Lenses
    Too commun, and stupid short on the tele side. 24-90 f 2.8 ( or even 2.4), would be way-way-way more interesting and useful. I would love some 90 f 1.7 D-FA 55 f 1.4 DC or hybrid screw-drive and ...
  • I would be tempted by a FF645 rangefinder, min. 60 MP and up. If I have to make with no SLR viewfinder, I would need something very-very serious in return... And by the way, this is Pentax SLR talk ...
  • Replied in Full frame
    Here is Pentax DSLR topic, so is targeting users of cameras with SLR optical viewfinder. I have zero interest in electronic viewfinder.
  • 20mm is way deep in the ultra-wide range, hard to correct a zoom from 20 to 80, and too beeg at f 2.8 for FF35 format. 20mm is a highly specialized lens, too specialized to be included in a ...
