  • In my experience, although they are graceful and appear to be slow-moving creatures, you actually do not have very long at all to react when they surface and/or breach. They pop up in all sorts of ...
  • In other words, "wireless tethering" (complete with LiveView) to a tablet ... great for product photography. It might be time for me to retire my K10D ... :-D
  • That's what happens when a photographer like Russ (a.k.a. "Kiron Kid") shows what the lenses are capable of (in the right hands) -- though "a few years ago" is probably over 5 years now. The 105mm ...
  • Have you checked by looking into the front of the lens (as if you were taking a selfie) to see if the aperture stops down at all? Set the shutter speed to 1 or 2 seconds and watch what happens. It ...
  • I haven't done a head-to-head of the 28-105 and 28-90 lenses. My 28-90 is M42 screwmount, which makes me less inclined to do frequent lens changes with that in the rotation. I have compared the ...
  • I own a copy of the Series 1 28-105 (Cosina built) lens but seldom use it, which doesn't make much sense because it's a decent performer. Significant lateral CA (green and purple fringes) at wide ...
  • Yes, if you buy the PK/A version (as opposed to the PK one, which doesn't have the electrical contacts visible in the pix on the KEH page that Ron linked for you) and the lens you use with it is ...
  • Darren -- I love looking at astro shots, and these look great. Never done it, so I don't know any of the challenges or special techniques, but I'm surprised you used the Bokina for it. I find my ...
  • Do -- provided the aperture blades move freely when you operate the stop-down lever, and provided when you hold it up to a light you can see the glass is clear of fungus. Any cloudiness, or white ...
  • Welcome to the wonderful world of the Kiron 105mm macro ... I have the Lester A Dine kit but without the actual camera body, and the ring flash has a Nikon module. Fires perfectly in auto mode ...
  • Sorry, I have no advice that you haven't already been given. I stopped using Flickr years ago, it seemed to get harder and harder to use.
  • I now see 16 albums, up from yesterday's count of 5 (but this is still not "most of them" if you have a total of 35.)
  • How many is "many"? I can see 5 of your albums when I click the link in your signature line then click "Albums" in the Flickr menu bar. Attached is a screen grab of what I see ... if you have other ...
  • ... and want a low-cost way to try out macro shooting, I recommend the Vivitar 2x Macro Focussing Teleconverter. It comes in both PK mount (the version I had) and PK/A mount (the version I have ...
  • A small scratch that you can barely see in good light? Forget about it. Read this post by Richard Cicala (read it all.) http://www.lensrentals.com/blog/2011/08/the-apocalypse-of-lens-dust
  • Scroll down to the bottom of the linked page -- it's free.
  • I understand your longing for a way to use Zuiko glass, I've never used it but have friends who swear by their Olympus gear (and the results they get back up their glowing words.) Could be there is ...
  • I hadn't used my A 35-105 for quite a while, but all the negative comments didn't match the way I remembered this lens so I took it out for a spin. Here's a link to a gallery on Picasa-web ... I ...
  • Same with mine. I have built a prototype "manual controller" that lets me dial in the duration of flash. One of these days, maybe, I'll actually finish that and turn it into something I can use!
  • Wow ... that's almost criminal. We've got almost the same gear -- mine is the Lester Dine edition of this lens, and the K10D. What a great combination for macro shooting (especially with the ring ...
