  • Yes, oil spots!! That's what they appeared to be as they were streaked/smeared. Very odd. I haven't seen such spotting on any other camera I own.
  • I meant to mention, that on the work order, it said: "Sensor is filthy. Needs serious cleaning.":-)
  • Just checking back in here. After almost a full 8 weeks, my SDQ has returned from Japan in tip-top shape, at no charge. Needless to say, I will be sticking to not touching the internal filter ever ...
  • I thought you might all find this interesting (amusing?). I got a VM from Sigma in NY regarding my sensor cleaning. It turns out that it needs to be sent to Sigma Japan for further assessment, ...
  • True. I tried it myself with Kolari’s hot mirror filter and the blue cast is quite noticeable.
  • Well, to be clear, each swab swipe was after a test shot with and/or without internal IR filter. It just got progressively worse. Sending it to Sigma today. I am still shocked that my powerful ...
  • Thanks, Tom. I am in the USA. Ugh. Most definitely a job for Sigma. I have already put in a repair order. (I just hope the sensor isn't damaged.) Needless to say, I won't be removing the internal ...
  • Oh dear, oh dear, oh dear... I have been manually cleaning my Sony's for years with no issue. This is my first time cleaning a Foveon. I used microfiber APS-C (16mm) swabs with VSGO's sensor ...
  • Thanks, dmmcoy and danski0224. I have similar. I ordered APS-C-sized swabs as I only have FF on hand. I am familiar with the single-side swipe technique. So I am comfortable with doing it this ...
  • Created discussion thread Manual Sensor Cleaning for Foveon
    Specifically on a Sigma SD Quattro... In the process of swapping the internal SDQ filter for IR tests, despite my best efforts at dry blowing (via Giotto Rocket) before every re-seat, it appears ...
  • Thanks to all who helped me out here. After much testing, I have decided to keep my IR and Foveon love separate-mostly to do with workflow and results. I'd like to think I gave it the old college ...
  • Yes. The 590nm filter I have is a red filter. But I don't know if it is also passing IR. OK. So if I use the image above called "Raw Channel R". But once in grayscale (and it already is exported in ...
  • OK, xpat. Thanks for your help! Making progress, I think... Amazingly, my Sigma 17-70 arrived today just two days after ordering from Japan on eBay (WHOOT!). So at least now I can take pictures ...
  • Thanks @danski0224. This AM I used a Nikon O-56 on my full spectrum-converted A7RII. I decided to try setting the WB as used on the Sony (3100K) on my SDQ (and same filter) in both STD and T&O ...
  • Created discussion thread Question about iOS Panoramas
    I was wondering if anyone knew why the stock iOS Camera Panorama mode doesn’t capture a full (rectilinear) 360 shot. While there are third party apps that do it, the stitching isn’t as good. I ...
  • Thanks. I wasn't aware of the T&O mode! Luckily, mine shipped with 1.13 firmware. So I was all set there. I shot in T&O and it looks more red now: But using any other filter (again 470nm, 590nm, or ...
  • Oh dear, oh dear. I am obviously missing a step here... Got my brand, spanking new SD Quattro yesterday. The good news is that in terms of color, while using an external hot mirror filter (Kolari) ...
  • Thanks, JohnK. That lens list is relevant to me as I am eyeing an SD Quattro bundled with Sigma 30mm f/1.4 DC DN (which appears to be near extinct on its own in SA mount). And that list says this ...
  • Thanks, expatUSA. Thanks for providing such a thorough response to my queries. This post should be a stickie! I AM looking for the Kodak Aerochrome look. Despite many tips and tutorials (and ...
  • Thanks very much, Col. I have been looking for such a forum on and off for years. So this is great! I have applied and look forward to participating.
