  1. Hey IKSLIM, had I needed to buy a new one for this update I probably would have sold you one, but Luca's kind offer is keeping both with me for now. Upon closer inspection the Apurture design version doesn't have the contacts I need camera side, so unfortunately you're out of luck unless I end up acquiring a 3rd one.
  2. I have been working with a digital logic analyzer and an Arduino nano. Via this setup I can set the aperture and move the focus to min and max so far. So the setup is For gathering data: Canon Camera + EF extension tube with AF contacts + lens, I have wired the extension tube to sample the data via a USB digital logic anlyzer. For testing my control: Arduino Nano + EF extension tube with AF contacts + lens (no body for now). So the aperture and focus max and min are working as controlled by the nano. Next step: NX camera + NX extension tube with AF contacts + Arduino Nano and
  3. Hey Luca, you've sabotaged yourself :P I'm holding out for the electronics now that I know they're coming. Even if there isn't AF working yet, at least so I can attach my chip in between without trying to machine my own holes or something. You've probably leapfrogged me by a lot on the electronic control, but if there's anything I can do to help let me know.
  4. Just need to use a Nikon to Canon adapter with it and you can use Nikon lenses. Of course some of the newer Nikons have the same annoyance as the Canon EF lenses in that aperture is controlled electronically, but if I recall correctly Nikon lenses will have the aperture closed all the way in that case while the Canon lenses are a somewhat more workable wide open in that situation. For Canon lenses you can use a trick to get the aperture you want if you also have a Canon body, what you do is to put the lens on the body, set the aperture you want with the camera on, hold down the DOF preview b
  5. Well, moving money to the smartphone department should be good for the cameras, since they've been in the same merged department since 2013 http://www.theverge.com/2013/12/13/5206560/samsung-merges-camera-and-mobile-divisions But I assume that they have also been putting the money towards phones even within the department :P
  6. Giving -200 error when I try to upload my jpeg, trying to use a lower jpeg quality to see if the smaller file size lets it upload. Hmm, no luck, says "There was a problem processing the uploaded file. -200" I have no idea what the problem is. Other files from the 5DSR also don't seem to be working. Well, just uploaded a 400mm f/2.8 shot to DeviantArt, no appreciable vignetting: http://ttbek.deviantart.com/art/Tiny-Rocket-658531277?ga_submit_new=10%253A1484922555 Hmm, now two Samsung files are having the same problem with uploading, weird, at least the first two here worked though. What
  7. Sorry for the delay, good to hear you have a solution, if you know anyone with a longer lens or a store that has one, maybe you could please test on a 600 or 800 lens. Here are the images with the 1st version NX-L attached. 5707:Canon 400mm f/2.8 IS L version one, 5708:Sigma 150-600 Sport @150mm, 5709:Sigma 150-600 Sport @600mm, 5710:Tamron 75-300 Vi DC?...mumbo jumbo the latest one @75mm, 5712:Tamron 75-300@100mm, 5713:Tamron 75-300@135mm, 5714:Tamron 75-300@200mm, 5715:Tamron 75-300mm@300mm, 5716:Canon 400mm f/5.6 L. 5722:Sigma 50mm f/1.4 Art glassless adapter, 5723:Sigma 50mm f/1.
  8. Double checked again without the lens hoods, it doesn't start suddenly but starts becoming noticeable around 150mm on my Tamron 70-300. By 300 it is clear and obvious, on the 400 f/5.6 the corners become almost completely dark. Different lens designs may make it show more or less, for example it definitely shows less on the 400 f/2.8 than on the 400 f/5.6. I'll try to post sample pics sometime later today.
  9. Hey everyone, I'm mostly quite happy with the NX-L, but it has a problem with telephotos >~100mm. I'm not sure if it is something avoidable with the design or not (probably not without using something other than glass?), but it has very strong vignetting in the corners, with my 70-300 (not really noticeable <100 but definitely there by 150), my 400 (5.6), my other 400 (2.8 and the issue is a bit less severe), my 500, and gets worse of course when used with a TC. Sharpness is actually rather good. I know I should still give you guys a more full review, we'll see how my time in the next
  10. Well... some bad news, the source I got 29mm from seems to be a typo, it seems the flange is only 20mm, which is still more than M mount, but that is very little space for the adapter. It will definitely have vignetting, lots of it ^_^. Maybe not too bad at some focal lengths though, not sure on that. When I'm back home I'll check out the protocol as best I can, no need putting in any time until I do that. Maybe the chip won't even be working, the camera shop I got it from had nothing to try it out on. The NX-Ls have arrived ^_^. Unfortunately they came through Q-post on this end, b
  11. No, the VL Eos adapter goes the other way EF lens -> adapter -> XL1 or XL2 camera I mentioned it only in regards to the XL cameras apparently using the same EF lens protocol for lens/body communication. What I'm looking to do is VL lens -> apparently non-existent adapter VL to EOS M with electrical contacts -> EOS M camera In fact, I can't find a VL adapter to any other mount, not even C-mount, probably because VL aperture is set electronically (just like EF... probably exactly like EF). . Even in this case, results will not be very good, because th
  12. Hey Luca, I have the chance to pick up an 8-120mm Canon CL VL lens (for their film/analog video cameras). From a cursory look it seems that the mount has the same pinout as EF, and at one point Canon sold an adapter to put EF lenses on these film cameras. Now, it makes no sense to try to go from these CL/VL lenses (29mm flange) to EF mount, but it seems like going to EF-M mount should be very possible and with the electrical contacts it might just work without any chips needed in between. I'm aware that the image circle is much smaller than APS-C for this lens, but with the new M5 at 24 MP
  13. No need for that in my case, Qatar has no tax on received items like this, lol.
  14. Hmm, registered is usually pretty quick, I think it will make it, fingers crossed. ^_^ And I think it end up through Fedex or DHL then as well on this side, probably Fedex.
  15. Hey Luca, I don't know, depends what kind of shipping. If Fedex handles it once it reaches here they will come to the house. If it is DHL, then probably as well, but if it is coming through the main post office they will send it back if I don't pick it up in like 2 days, so in that case it still works if it arrives before I leave, but otherwise be checking the return mail. I guess we'll just hope for the best and I'll give you an update if they arrive or before I leave if they don't.
