  4. Hi Elmer, Yes you will definitely need some buoyancy, how much will depend on the combined elements of your rig and how close to neutral you want the system in water. It is always interesting to see other photographers solutions. I use home made cork collars around the port and a couple of fishing net floats at the back of the housing over the viewfinder. Whether you home engineer a solution or use commercially available floats/arms you will need to experiment with quantity to find the best lift combination for your needs. Mark

  10. Hi Alex, Did this lens come from a movie camera housing or a stills camera and which housing was it designed for?.....if stills what film format? I am just fascinated to know where the adaptor originated from and how old it might be? If the design truly can be used with any lens (excluding fish eye) then it is a very interesting trial indeed!

  11. The upgrade to LR5 was for the D7100, but I had been using LR4 in 64 bit mode. However the problem did not appear until I upgraded to 5.5 in the summer, so perhaps that version needs more RAM? Anyway, I am please to say that it has gone for now! Mark
  12. OK...so I have set up the new laptop which has 12gb of RAM as opposed to 8 on the old one.....imported 800+ images from a card (shot on D7100) and there seems to be no corruption on any of them. These are the same images and the same card that previously produced the corrupt images above, so perhaps it has been a hardware or memory problem all along? However, this still does not explain why I had no problem prior to upgrading to LR5? Mark
  13. Hi Adam, D7100 and I had no problems until I upgraded to LR 5.5 or 5.6....with quite a number of other similar issues for others emerging it seems that LR may be the source of the problem after all.I have just bought another PC (in the Xmas sales!) so will upload softeware including LR 5.7 and see if the problem persists. Mark
  14. Hi Tom, Many thanks for your detailed reply. I had looked on the Adobe fourums and there are others with this issue, but of course as you say the Lightroom gurus claim it is impossible and must be a hardware isssue. I have a friend who uses Mac and he also has this issue occasionally since upgrading to LR 5.6. However, I won't be signing up to the cloud to resolve the issue, Adobe have had too much of my money already!! Mark
  15. Hi Coinee, My IT knowledge is very basic to say the least, although I am beginning to wonder if it may be my PC. I have tried importing from the cards and from various external drives in different sized batches. Sometimes in a batch of say a dozen only one or perhaps no images are affected. It is not always the same image so perhaps it is a memory problem. I upgraded to a D7100 late last year and had no problems until I upgraded to Lightroom 5.5 in the summer this year so perhaps there are changes in the software that require more memory or graphics requirements. I am in the process of looking for a new laptop so hopefully that will help. I have managed to work around the processing of the current images from my last trip by importing in small batches and eventually getting the images I want without the corruption! Too much like hard work though! Mark
  16. Hi Alex, I have tried importing from back up drives and directly from cards. Another strange feature is that if I close Lightroom and shut down the computer when I restart some images affexcted are OK and others that were previously good are now corrupt! So that makes me suspect an issue in Lightroom but of course Adobe says there is no issue.... I will try the DNG trick and I think also load Lightroom to another computer and see if that changes things. This all started after I upgraded to Lightroom 5.6 and 5.7 has arrived quite quickly which makes me wonder, but upgrading has made no difference. Mark
  17. Hi Steve, This problem appears with multiple cards and the files are not corrupted when viewed in other software. The previews initially load normally in Lightroom and look fine to begin then after a few minutes these lines begin the appear. It can be random, i.e. if I import the same group of images more than once then it will not always be the same image that becomes corrupted. It is driving me nuts as you can imagine! Mark
  18. Hi All, I have recently been suffering a problem with Lightroom 5 (now 5.7). When I import RAW files the preview have random corruptions whic appear as multi coloured lines or tearing across part of the image, generally from the bottom of the image. This was happening to random images in an import, but now seems to be affecting nearly all imported images. I have tried a number of things, repairing/reloading the software, deleting the preview caches etc. but no success. The pictures view and edit with no problem in Photoshop and Nikon View etc. Hopefully you can see the attached image. I am hoping soeone else out there has experience a similar issue and perhaps can offer a solution? Cheers, Mark
  19. Subal ND20 with D300 Conversion Kit still available and open to offers!! Mark
  20. Hi Pete, I serviced it myself a few months ago and have been diving it regularly since then. All functions work perfectly - the housing will come with a tray for the D200 and D300 so that either camera can be used. I replaced the original plastic cold shoe accessory mount on top of the housing with an aluminium one, but I still have the original which will come with the housing. Mark

  24. Try cerium oxide on a felt buffing pad with a dremel or low speed drill with frequent breaks to let the glass cool. It is a slow process but will remove scratches from a glass dome. The wall thickness of the glass is of course reduced locally at the scratch location when you finish, but any distortions will not show underwater. Mark
  25. The rumours I heard on my last visit to Lembeh were that the Rhinopias had been collected for the aquarium trade, which is very sad. In Ambon in December I saw five different individuals and the guides told me there were up to twenty throughout the bay. Ambon is the place to go at the moment.
