  • One thing that seems to have been missed in this discussion is the highly useful flexibility of full-time live view (not just "locking up the mirror" on a traditional mirror-based DSLR), but as a...
  • In today's most current digital cameras, there are actually several filters that are "sandwiched" together, to become called - collectively speaking - the camera "sensor" array. Stacked filters,...
  • Indeed. The quartz / fused-silica glass panel that replaces the camera's surgically-removed "hot mirror" filter is much more resilient, and just about impossible to scratch or damage. It is, in...
  • These images are wonderful. Great work, there!
  • I can answer that for you. The reason it matters to have the ability to store custom white balance for IR exposures, is because the RGB allocation matrix in a non-specialized ("normal") camera is...
  • Let's not forget the older, "legacy lenses", from the film era. Sure, they are manually-focusing, but ... because many of them were designed for the full-frame image circle (instead of the smaller,...
  • Hey, there. Somehow, I missed this post asking for suggestions. Not sure if you already made a choice by now, but if not, here are the absolute essentials: Traditional, mirror-based / optical...
  • Your wish is my command. See the new test photos, with associated data.
  • Why would a person such as myself, who us committed to objective exploration and knowledge gathering ever have any use for being offended? If one should get offended at someone who is more...
  • Replied in Is it f/2?
    You're right. But since this lens has proven itself to be tack-sharp even for non-macro focusing all the way up to infinity, then f/2 DOES have its uses, just as it would in any other lens....
  • Back from testing this macro lens some some, per requests. :-) Here are the results! "Dogbane Beetle" (6 to 8 millimeters body length. He is tiny!) - Lens mounted on Panasonic Lumix G3 - micro 4/3...
  • By the way, I have learned from experience that since digital sensors are MUCH more sensitive to IR radiation, as compared to UV-A (and the fact that many modern lenses introduce additional UV-A...
  • Wfektar, I am most certainly going to test it under more diverse shooting conditions, aperture settings, lighting variations, and even wavelength bandwidths (since I shoot it with a full-spectrum...
  • Richard, Thanks so much! Yes, I was worried. Like any other "stab in the dark", when you deal with older, well used pieces ("legacy lenses", as they call them). But, I trusted the particular...
  • Neil! Thanks for the reply! Funny, I have a good friend, with the same identical name as you. For a second, I thought you were him ... but then, I saw that you hail from Australia. Anyway, I often...
  • Getting back to all of you, now that I have had the lens, and have been able to extensively take it through its paces. Yes, this 55mm 1:1 macro lens DOES turn out to be of a genuine f/2.0 aperture...
