  • AF is about the same on both. As for IQ, it depends on what you're looking for. My primary use for both of these lenses is people shots, and I think they both excel at this in different ways. I ...
  • Really nice set. I especially like the colors in that first one!
  • Really nice - especially #2 and #3.
  • Replied in Maine Images
    Beautiful series of one of my all-time favorite regions. If I could, I'd get up that way every year, and I still wouldn't get tired of it. I really like your shot of The Bubbles, with the grassy ...
  • I did. No difference.
  • I tried it in another Windows computer at work today, and it gave the same result: showed up in Device Manager but not File Explorer. And neither my coworker nor I have admin privileges on our ...
  • Thanks for the explanation. That makes sense.
  • This is helpful for future practice. Thanks. So does this mean that SD cards behave different fundamentally than solid state drives in the way they save and retrieve information? I've never really ...
  • $12 for a new 64GB Lexar Pro. Easy fix. Just for fun I looked at Quicken to see how long I've had that card. Four years and a few weeks. I got my $15 worth out of it, so I can't complain. Thanks ...
  • LOL! Very well put.
  • Reformatted in the camera, no problem. Shot a few images and saved to the card just fine. Put the card in the laptop's card reader, but the card didn't show up at all - neither in the file explorer ...
  • This explanation makes the most sense to me. It is card-specific (as opposed to the card reader, USB cable, etc.), and it explains why the card can still be mountable on one device (the camera) ...
  • Not sure why I didn't think to try that before. Just did it, though, and unfortunately it didn't solve the problem.
  • Good suggestion. I'll take it to work with me on Monday and try it in a coworker's laptop. I did reboot the laptop, but no joy. At this point, the only thing I can think of is that maybe there's a ...
  • Created question thread SD card trouble
    I have my K-3 set to record images on SD1 and movies on SD2. My usual practice for downloading to my computer is to remove the SD card from the camera and place it in the laptop's SD card slot. Bu ...
  • Surprised to hear you didn't like the output of the Sigma 17-50, but everyone has their preferences I suppose. With that in mind, the combo discount you mention here sounds like a good deal. You ...
  • Replied in Sigma 17-50
    Of the ones you mention, I would go with the Sigma 17-50. I recently bought it, and so far it has lived up to its reputation. It's fast enough and sharp enough that you wouldn't need a prime in ...
  • Beautiful images! My wife and I spent a week there about 15 years ago, and it still remains the most magnificent place I've ever been. Your photos are a fun trip down memory lane for me, as they ...
  • Both of those are reasonable explanations. Then throw into the mix the news that Sigma will no longer be making K-mount lenses. Who knows?? I'm just glad I got a good deal on the 17-50 a few weeks ...
  • Well the 17-50 is easy to explain: it's a constant f/2.8 aperture, and it has Sigma's high-end glass. I've had the 17-70 for years, and I just recently purchased the 17-50. The 17-70 is nice for ...
