  1. I think once you place that set up in a housing you have a higher risk of overheating On land it will do fine especially if you lift the screen Sent from my SM-A505FN using Tapatalk
  2. If you buy a type 1 you can then buy the type 2 ring and vice versa Typically ikelite housing have type 1 Just measure the thread distance from the glass type 2 is practically flat or 1mm in type 1 is deeper Sent from my SM-A505FN using Tapatalk
  3. I think this is very useful on land but not so much underwater as the screen will lay flat and the housing already has space for disk and batteries so not worth invalidating the warranty
  4. Mobile phones have killed compact cameras together with GoPro. Today there are very few cameras that work as the old canon used to do. With my wife old Canon S95 some wet lenses and two strobes my wife could take wide angle and then super macro Today all compact cameras are either advanced sensors or super zoom so there is a need for a port system as result housing if they exist are aluminium or in any case much more expensive The wet lens paradigm has shifted to micro four thirds currently the only system that can go ahead with a single port but obviously much more expensive than Canon used to do. The sad story is that there is no money to be made so Canon has left it to Meikon and similar to deal with and is not really bothering with the cameras anymore after all underwater imaging was never a priority it was easy to make up a polycarbonate housing and this gave access to functionality but now there are simply no cameras fitting the recipe
  5. Possibly but that's a special topic I would say Sent from my SM-A505FN using Tapatalk
  6. I decided to do a full write up as I see a lot of confusion on this subject. https://interceptor121.com/2019/09/14/which-macro-lens-to-pick-for-your-gh5-or-micro-four-third/ The same logic obviously apply to full frame but the lens examples would be different
  7. This thread inspired me to write a post https://interceptor121.com/2019/09/14/which-macro-lens-to-pick-for-your-gh5-or-micro-four-third/
  8. As far as I recall from Nauticam the CMC-1 or no diopter can bring more magnification to the 30mm as the minimum working distance of the lens is shorter than the CMC-1 on its own. I would like to run some tests to confirm but generally nauticam is correct and they do field test The 30mm minimum working distance is 10.5cm - length of the lens 6.35 cm - 2cm to focal point on the camera this lens focusses at 2 cm from the port so the benefit of the cmc-1 would be really minimal to none In terms of depth of field once you reach the same level of magnification there are no difference on focal length so 30-45-60 are all the same once you get to the same size subject in the frame
  9. I also wanted to add the fact that while the best focal length is 45mm both the Panasonic 30 and Olympus 60 are sharper than the leica 45 despite lower cost so you can buy both lenses For portrait a zoom lens 14-42mm works fine if working distance is a problem you get a diopter So the priority list for me has been Olympus 60 Panasonic 14-42 for video And there have been some rare occasions where the 30mm would have been useful as the 14-42 covers that focal length fine and you can add a diopter To date I have not bought it If you start with a 30mm you will need the 60 the moment you go to a super macro destination and if you get the 45 port you will need the 65 or 20 extension however the 45 does not work with the 14-42 If you start from the 14-42 you get the 35 port than 30 extension for the 60 and 17 for the 30mm Sent from my SM-A505FN using Tapatalk
  10. There is no lens not vignetting with the LX10 because the lens becomes longer when you zoom in so there is a gap to the port. The performance also depends on the housing you use and the distance between thread and glass Sent from my SM-A505FN using Tapatalk
  11. The CMC-2 on the 60mm provides no magnification as the camera working distance does not improve materially The 60mm needs the cmc-1 and then captures an area of 9mm width The cmc-2 on other lenses does not provide the same magnification of the 60mm but is definitely much easier to use especially for video Even with the 12-50 I would go for the cmc-1 if a macro lens is not required Regarding the 30mm it is good for larger subject but makes it very hard to isolate them so not good for small things on sand rocks Sent from my SM-A505FN using Tapatalk
  12. Buy the Olympus 60mm as a priority The 30mm is wide for many situations and the 45mm Panasonic is slow to focus
  13. Both cameras have 1/250 sync speed The d7200 had an internal flash with auto fps mode this increases the speed to 1/320 The d500 has no internal flash so it stops at 1/250 If you see a black line it means the camera is capturing the rear shutter window Sent from my SM-A505FN using Tapatalk
  14. The GH5 and the EM1 share the same sensor however Panasonic and Olympus have made different choices in terms of construction of the camera. As result the GH5 has slightly better color and dynamic range but the EM1 has some more performance a higher ISO we are talking about small differences. In terms of video Olympus devices have always been lagging but now they are decent. When it comes to still features Olympus is better than Panasonic at focus and other features, The other factor to consider is that the Panasonic m43 work well with any lens brand, the Olympus camera prefer Olympus lens and give some side effects with Panasonic lenses. For macro you can use the Olympus 60mm for most and for wide angle the 8mm Panasonic if you use the GH5 or otherwise better the Olympus for their EM1. For video the approach is different and I prefer a 14-42MM zoom with wet lenses wide and close. You can of course use this as a platform for stills and it does better as wide angle than macro where even with a strong close up lens you cant beat the 60mm
