  1. I've just sold on my final CF-equipped camera body and so have some CF cards left over - these are Compact Flash CF not CFExpress. If they are of use to you, let me know. I'm happy to send them on for the cost of mailing. They are: 2x Lexar Professional 800x 64GB UDMA7 2x SanDisk Extreme 60MB/S 16GB UDMA I also have available the excellent Lexar Professional Workflow HR1 tower which holds 4 cards reader in slots. I have the CF and SD card modules available which fit in it. See separate post below.
  2. Hey Chip You don't find having the Catalog (as opposed to the actual images) on an external SSD slows things down a bit? I tried this system - which seems ok - but after watching Scott Kelby's video I figured having the Catalog on my Mac Studio's internal SSD was a better way to go. It does seem slightly faster. But your point of being able to pick up the external SSD and work completely away from a main desktop, is good. Do you know the overall speed of your external SSD drive? I did find upgrading the USB-C cable to a 20GB/s capable one made quite a difference when plugged into USB3.2 port. It's now my SSD enclosure which seems to be the speed limiting factor and I'm looking to upgrade it. Naively I thought you just slapped a SSD into a housing, plugged in the right fitting cable and away you go! Advice from makar0n and Rich opened may eyes to whole new world of extra speed, complexity - and cost. Who knew? Well, clearly not me.
  3. My guess is that with a 9mm on an APS-C sensor at f11, almost everything is going to be in focus if you set the focussing spot slightly back from infinity.
  4. You've made Oskar a happy man.....🤣 Congrats, @Landvogt1893, get some great pics with them!
  5. Super images, Chris!
  6. Hey Ben! Great to have you with us. A warm welcome.
  7. Is a 20cm close focusing distance the ideal across all domeports? If so, that's a pretty useful rule of thumb.
  8. You should have this: Bottom right hand corner: "Unread Activity" and "Mark site Read"? Tim
  9. Errr, that’s odd. I’m using an iPad and I can see Mark as Read at the bottom on the Critter ID thread. What device are you using?
  10. Interceptor121 85 Posted yesterday at 01:09 PM · IP I think this kind of solution is expensive and not effective In many cases poor performance is due to lenses focussing too far requiring domes too large or even more common incorrect calculations of the position of the dome I have not had an issue with edges moving from MFT to full frame the key is to choose the right lens Quote TimG 390 Posted yesterday at 01:47 PM · IP I've got no personal experience of the S&S but I seem to remember a number of folks using them and being happy with the results especially, if I recall right, using lenses like the Nikkor F 16-35 and Z 14-30. Good though you've had no issues. Good choice on those lenses! Quote Phil Rudin 69 Posted 1 hour ago · IP I agree with 121 that proper port size and extension length are required for best corner results and of course full frame suffers more than sub full frame given the same F/number. However I have done a number of tests using like equipment, example Tamron 17-28mm and Sony FE 16-35mm PZ in 180mm dome with and without the S&S conversion lens and the S&S always bests the native lens by at least one stop. I have also used the S&S lens on fixed lenses like Zeiss Batis 18mm with similar results. I also agree with 121 bout minimum focus the Sony 16-35 PZ minimum is 24cm, Tamron 17-28 is 19cm and the Sigma 17mm F/4 has a minimum focus of 12cm. For wide rectilinear I would chose the Sigma 17mm over the other two even without the S&S because of the close focus. It is outstanding in a 180mm port but I have also used it in a 140mm port because it can focus closer than most fisheye lenses. To get a one stop increase for $600.00ish is the question and it appears that several have found this worth the cost especially if the alternative is an expensive water contact lens. The second issue is if you are on team rectilinear or on team fisheye. Many would rather just go fisheye to reduce corner issues. Image is the Sigma 17mm F/4 in the 140mm dome port at F/11 with the port glass touching the pool light glass, A/V light. Quote
  11. Hey mandab! Welcome to Waterpixels. Excellent to have you with us. I can quite understand that move to Oz......
  12. With the news that the S&S correction lens may be staging a come back, @Phil Rudin suggested we start a thread for it. Good idea, Phil!
  13. Guys - I've set up a thread for this now......
  14. HI awe. Welcome to Waterpixels! We hope you really like this new forum.
  15. I've got no personal experience of the S&S but I seem to remember a number of folks using them and being happy with the results especially, if I recall right, using lenses like the Nikkor F 16-35 and Z 14-30. Good though you've had no issues. Good choice on those lenses!
  16. Divers24.com reports a fire, this time in the Red Sea, on the Sea Legends. Keep an eye on those lithium batteries, people!
  17. Edge sharpness with wide-angle lenses underwater can be an issue especially for users of full-frame sensor camera bodies. One solution to increasing edge sharpness, which has worked for some photographers, has been the Sea&Sea correction lens which came in 77mm and 82mm diameter options. But this lens disappeared from sale a little while ago. Waterpixels member @Ido has been in contact with Sea&Sea and has been told that the company plan to make the lens available again later in the year. So if you have been hunting around for the Sea&Sea correction lens and have given up hope, all is not lost...... hopefully!
  18. Thanks for posting that, Ido. Good to know. I'm sure there are a few folks who would be inserted to know when the lens becomes available again.
  19. The March/April edition of the excellent Underwater Photography magazine is now available http://www.uwpmag.com/
  20. Yep, as Barmaglot says, don’t! It’s unusual for an u/w image to look seriously fisheyed - unlike a topside shot. You use the FE to get close but also to provide wide at the same time. I think it’d be pretty rare that you’d want to lose that.
  21. Hey Simon Excellent to have you with us. Welcome! I'm sure you will see lots of familiar name short from Wetpixel.
  22. Hey John Great to have you with us. Welcome to Waterpixels! We hope you really enjoy the site. Tim
  23. I had the same thought. Macro lenses are ideal in conditions of poor visibility. You are usually shooting something only inches from the port so viz is, generally, not an issue. This arrowcrab was shot in awful conditions using a 105mm lens
  24. I would not have thought so. Great for over/unders!
  25. Chris is right on the issue of which carrier you use. Often using a low-cost airline is not, err, low cost. So many add-ons. We've had really good experiences with Air France, KLM and Emirates. Yeah, they cost more but when you start adding in the add-on charges that low-cost carriers raise, the different shrinks rapidly and allowances for baggage increase.
