  1. Graag gedaan. My German is also not that good, but I think the Traumflieger site is a great resource. Off course it is nice to have the options (although then there are even more options to choose before the dive). the technique with the star button is also possible on my camera and is 'back button focus' in most english articles. You could set this setting to your C mode so it doesnt bother your sister as much.... If the exif is not transferred, then the Tamron electronics might not be entirely the same as the kenko. If the camera is adjusting the exposure then it is just a little annoying, if the camera just acts like it is not there then it might not be usable. If the camera locks up with some combinations you really would like to use, it is probably wise to look for a different one. If I reread your first post, the 1,4 converter does not lock up, that is the 2 converter you already own (and the same type as my 1,4). If we lived closer (my Hasselt is the one near Zwolle, not the one in Belgium) or dived in Zeeland at the same time you were welcome to try mine out, but that wont happen in the next week when you need to make your decision. PS: I dont think Magic Lanter will help with communication issues between lens and teleconverter.
  2. PS; if you read German (or dont mind google translate), an interesting test of converters is found on http://www.traumflieger.de/objektivtest/open_test/telekonverter/overview.php
  3. If you need a teleconverter on all your lenses, would you not be better off shooting with a crop camera ? My Kenko teleplus 1,4 converter has exactly the same type number as the tamron telconverter you are mentioning, so there might be something in it that they are the same. At my camera (canon70D) the displayed f stop does take the converter to account. Also in the exif, the focal length is adapted. I think it is odd that the info is displayed and adjusted in my camera and not in yours. when I use it with my f2.8 USM 100mm macro (not the L lens), I have to take care to avoid using microfocus adjust. for some reason, the camera will lock up (or just not release the shutter) if I use this combination (100mm, teleconverter + microadjust). If it is working, it is reasonably fast. If you would use a teleconverter and a diopter together, you need a good focus light, or be probably better off prefocussing at 1:1 and shooting when the image is sharp in the viewfinder. The canon teleconverters are really only aimed at the longer lenses, and wont work with wide angle and macro lenses (although they would match up nicely with your 70-200mm )
  4. And keep in mind that he lens is still not a ff lens. Verzonden vanaf mijn iPhone met Tapatalk
  5. Have a look at the trick used in this thread to zoom a fatter lens than usually is possible. "Sigma 17-70mm F2.8-4 DC Macro OS HSM", which Ikelite port? https://r.tapatalk.com/shareLink?url=http://wetpixel.com/forums/index.php?/topic/39932-%22Sigma-17-70mm-F2%2E8-4-DC-Macro-OS-HSM%22%2C-which-Ikelite-port%3F&share_tid=39932&share_fid=58055&share_type=t Verzonden vanaf mijn iPhone met Tapatalk
  6. Does the 50mm 1.4 focus really close? Most seem to favour a macro lens in the 50mm or 100mm range. 24 mm is not that wide although I liked it when I used film. Do you use a full frame or aps sensor? As for the port, if you want any wide angle benefit you'll want a dome port. Ikelites 4 locks port system is limited for 'fat' lenses, the new port system is larger. That is probably why some lenses are not listed. Verzonden vanaf mijn iPhone met Tapatalk
  7. If Andreas needs another reference, I can give a positive one too on the clamps I bought from him. Verzonden vanaf mijn iPad met Tapatalk
  8. Sometimes stuff breaks. Get a bit of bungee for a few $$ and repair it... I dont really see the problem...For unbreakable, move to spring straps....
  9. PS I don't quite understand the negative space or swirl explanation. The subject say 20cm would be larger then just the anemone fish say 10cm. So to have that at 1:1 you would have to have a sensor of 20cm. (Instead of 10 cm ) Verzonden vanaf mijn iPhone met Tapatalk
  10. You could also read the rules as 'any shot with a macro lens capable of 1:1'. Competition I entered had 1:3 or greater as definition, but I'm sure that is not actually enforced. I think the approach of 1:10. - 1:1 as macro and beyond that as super macro would be a quite logical approach. I don't think a strict enforcement is really necessary.

  11. I'm confused. The specs of the air filled diffuser that is almost clear say -1 EV. The specs of a milky water filled one day minus 2/3 EV. Someone's specs must be off. Verzonden vanaf mijn iPhone met Tapatalk

    Is it safe?

    I've bought stuff from here, via eBay or directly. Never had a bad experience. There is a also a thread with feedback on buyers and sellers. That lists the odd bad experience. For larger stuff, PayPal gives a bit insurance. My first digital housing I got second hand and used an escrow service. Verzonden vanaf mijn iPhone met Tapatalk
  13. look like words to me :-) maybe include a picture or video ?
  14. if shipping to the US is the problem, you could try Kevin at Aquaphot in the UK. He has repaired Ikelite stuff for me a few times.
  15. I read your post more as an instruction. I would say if there are only two wires connected it would be what you want. Could there be some interference in the circuitry, maybe best to totally bypass it. My Ikelite circuitry broke when there was a small flood in a strobe. Kevin from aquaphot bypassed it.

  18. Its a special gemeente (council), so yes.... and now, you're right on the mission. A nice joke on this is the underwater photographer who says on his deathbed 'dont sell all my uw gear for the price i told you it costs' Vinkeveen is allright as a freshwater dive, but Zeeland is really nice, and it is not always raining here like in Manchester (my wife is british and lived there). If you ever feel the need (maybe when its warmer again), give me a PM....
  19. thanks Tim, i remember you offering the 3inch stick arm. I had a holiday in the states and i picked up the remainder there. its not that the old ones didnt work, but ive become a bit frustrated with the "grinding". I bought an extra long clamp for my focus light as well, so the mission is now complete... are you diving in the Netherlands as well ? Gerard
  20. Yep, TimG is spot-on, just bought twice (actually, it was the 3th time). when I started i had a 1,25 inch ikelite ball system that was very heavy (with an older strobe i also had their pipe system). Then i changed to a cheap (even not so cheap) version of the 1 inch ball arms. These were from i-das. the clamps are so sharp, that the paint / anodisation on the ball heads has stripped clear. Also the orings on the balls dont last very long. I now changed to ulcs (but with original oring-less strobe connections and a cheaper ball on the strobe from onderwaterhuis.nl. Havent got that new arm system wet, but i'm sure it is better.
  21. The linked video seems to be gone? Verzonden vanaf mijn iPhone met Tapatalk
  22. Just to add to the confusion, the 70d and later dslr from canon have dual pixel autofocus with tracking, also during video recording. Verzonden vanaf mijn iPhone met Tapatalk
  23. Ps. Lighting wide angle scenes at a distance is quite difficult with the ds51. It is better suited for cfwa. Verzonden vanaf mijn iPhone met Tapatalk
