  • Some thoughts: I don't mind the more central cropping since the clouds, to me, are a point of attention. But, in my rendering (below) I tried a "different" rule of thirds. I think the canopy, not ...
  • We print mainly for art display in our home. It's just a different thing, to select a tiny fraction of your photos-- the best of the best --for everyday display and for everyone who comes to visit. ...
  • At 12 mm (24 mm full-frame equivalent), 20 secs (actually, 21) IS the rule of 500. I have used multiple shots to compose star trails (stacking), or into time-lapse movies that show developing star ...
  • Replied in Not really
    You mean the 12-50 is not very good, I think. But, yes, good qualification. I was coming from the 12-50 and that specifically felt like a transformation. I don't mean to dispute other lens's being ...
  • Pretty sure this is incorrect. The key parameter is WHAT PROPORTION OF THE SENSOR is covered with a certain angular span. So, at a given focal length, you need to multiply the full-frame limit by ...
  • Chortle. Thanks for the laughs! I've seen robot shots of big game with wide-angle lenses--great--but not anything I want my own body to accomplish.
  • Replied in Not really
    Just a contrary point of view: In my estimation, what you say is not correct. You can, for example, just check the comparison I did under "light and sunny conditions" in my post above; link to ...
  • Here's my "translation" of transformational: Does it make a subjectively obvious change in the way you perform or experience photography? Obviously this depends on the person answering: Does the ...
  • Replied in Nice ..
    Pretty sure this was from Little Tubu camp in Botswana. We were there just a few weeks after it opened. Tiny, but really wonderful. Our whole trip (Zambia, Botswana) was just great. Here's one ...
  • Replied in Thanks
    LOL! That's pretty much exactly what I had in mind! Here's an aftermath. (Never managed to catch the crucial action, per se.)
  • I think I can see what you might like about this pic (action, bright red ball), but I actually preferred your other shots--well, at least the bear fight and the panda. The bear fight had more ...
  • One thought on focusing... I have only done a few star shots, but I have not had any trouble focusing. Instead of using BRIGHT stars, I used DIM ones. I found that out-of-focus dim stars just do ...
  • These are pretty fabulous! Great to see them. Thanks. One "niggle": I think the last is pushing the red channel to the max, losing texture. Here's what the exposure meter sees (luminance), and it's ...
  • Well, totally convincing on the sharpness issue. Also convincing that you have to think a fair amount about depth of field. I wonder what you think about lightening up some of your subjects, like ...
  • Long FL stabilization is most critical to me. Those once-in-a-lifetime safari shots are what I'm after. E-M5 with monopod was quite good, but still occasionally fell short. Seeing genuine 4 stops ...
  • Good point. The in-camera chips are indeed (I imagine) optimized to do the operations they need most quickly. However, (1) Typical modern PCs have quite huge processing capabilities, which don't need ...
  • Just a few comments: On our last safari, I took two bodies (2 x E-M5) and ALL my lenses at the time: 75-300, 12-50, 40-150, 20, 9-18. I did not regret it for a minute. Everything had its uses. I ...
  • Nothing helpful, here, but sympathy all around. I like starting with the built-in Olympus look, so the Viewer works well for that. Slowness is a bit of a pain, but since I only use it for ...
  • Hmm. It looks like a deeper depth of field than my 12-40. I'm surprised. But, I take your point Sorry, no. I'll see if I can find out. We live in Berkeley, CA.
  • Dang, can't go wrong! Took my 12-40 out, and this is what I got, at 40 mm. (MF tweaking necessary.) Too thin a depth of field?
