Hi @RobinD It's really not a nice construction. I'll never trust such a 3d printed part. Not with one or two expensive lenses. You wrote that you are using this part since 5 years... how many dives in salt water ?

Thanks David for your point of view... I don't agree all what you say but I (trying to) understand it. I'm a hobby photographe and happy with that. I allways avoided to make some photographics workshop.... why... I don't want to heard from the teacher.. You must do that or that. In all cases this workshop will have some influence on me. I've my feeling... my approach of what I want to obtain... I'm not trying to copy what the other made... I want to make photo I like... no photo for the others. If some others like it fine ;) The only "workshop" was a masterclass of Alex last year. I paided to learn some technics It was interesting.. I'm using some technics now...

Good explanation of the situation. It's the same for me.

Very good. ❤️❤️ I'm in the renew of my computers... my new RAID is connected on my PC.. BUT the plan is to build a new "server" under Windows 11 (I know I know... but it's not the subject of this topic... ;) ) I'm not alone at home others are using my "server"... but a very important point is that the Server and the backup (for you the 2 NAS) need to be on 2 separated "location"... in case of flooding, fire or intruders. In the past I made the backups automaticly on HDs connected on my PC... I'll make the same again in the futur ( my PC is in reality a server case with a lot of HDD and SSD ;) ) Before I worked with tape.. but todays it's to slow.. and HDD are so cheap.

In the past I had much more bad shoots... but since I have the R5... the bad shoots decreased a lot.

My old RAID 6 + spare was exactly 16 years old when I shut it down. Yes 16 years. Not a single HD failure, A dedicated RAID controller (Adaptec) All based on a MS 2003 server... The only problem I had was when I shut years ago the server down during holiday ... when I came back the Motherboard was dead... I bought a new one and that's it. RAID <> Backup RAID is only there to reduce the chance to need a restore of the backup HD... ;) And you know Backups... I make 1...2 ... each month after that ... it ends to 1 backup / year 🤣 ( fyi I work in IT) To days you have On-line storage in the cloud for realy sheap..(MS office 365 as example.. ) 1TB / user if you buy the familly you will have a lot of storage and more for lees as 10 € a month

HDD are cheap --> why should I spend a lot of time to delete the bad, sorry not very good photos ? During the diving trip I spent 1, 2 or 3 hours to delete the out of focus etc pictures. maximum 5% I guess. I make every 2 or 3 days backups on 2 external SDD the number of pictures / day are beetween 200 and 400 sometime 500. When I'm back home make a copy of the folder (year/month/day) with the Raw and the LR xmp. A Sync on LR at home and I can work on the new pictures on the big screen. I have since more than 15 year a RAID 6 , with 7 HDD and one spare.. but I ran out of space (not only because the photos) I made every months some backups on separated hdd. Now I use only a RAID 5 with 3 HDD +/- 30 TB and I shut down the old server with the raid contoler and the 8 disks. I have enough old HDD with a lot of backups of my pictures... comming back from 6 diving days in Ustica... 12 dives --> 80 GB and 1900 photo.. 🤣

For sure. I have booth on a flip.... but for me the MFO-1 is realy a good lens. As I allready wrote the focus stay near and don't go on the background. and that make the difference beetween fighting to take photo from a small goby and only take a photo from a small goby.

Hi Alex Thanks for the explanation I'm using the Canon RF100 and YES a lot of time i was frustrated having a to big magnification. Did you have some indication of the price?

I move from the screen to the inon 45° viewfinder one year ago. For wideangle it s not necessary in my opinion... but for macro I can imagine shoot without the viewfinder now. Isotta housing with Canon R5

and no Canon 🥴

A smile of a woman help... for sure. 😜

Thanks That is the next step... in the pool ;)

I hope you enjoy reading the building process of my new snoot. One point I find that the position of the lens, the lenght of the tube and other details are very important. 5 mm change a lot but It seems that the actual setup is good now.

I allready build some test parts to put on the top of the snoot to change the focus, size and the shape of the light. I'm not happy of the first test I need to make some more experimentation. The idea also to made a add-on with a diaphragme in it. to change the size of the spot light. All this part will be stackable But for the moment I need to test the main part of the snoot under water to be sure that it is correctly sealed and to show the result of the light output.

Hi The project is one step futher. I sealed the lens and glass with silicon. After that I glued the pieces together with epoxy and cover it with epoxy to ensure that no water is going in the snoot. I screwed the 2 part together.. there is an O-Ring. That is the result. As you ca see there are no reflexion the circle is clean

Sorry "If you want the STL feel free to ask me"

Hi Alex What will be the job of the MFO-2 ? Hugues

I'll follow this subject then i'm looking for a fisheyes solution for my R5.

Hi I build 1 or 2 years ago this connector The target of this item is to bring the FO cable near of the arm without a large amount of cable and avoid to break it if it is catched in someting Easy to remove And the small black part is allways protecting the cell of the Retra The FO is going into the arm.. clean On the top coming out and go in the big floating arm and again comes out near of the housing where the FO is attach with my selfmade connector All this pieces are printed with TPU If want want the stl feel free to ask me. Hugues

I have only one catalog it work really good. And that on a more than 0 years "old" PC under windows 10 with 32 GB RAM. 18.6 GB for all the pictures I took over the years 164720 pictures I agree with you it is a great feature of LR to be able searching ALL my picture in one step... and that very fast.

It's not totaly false. 20 TB or more for less as 400 € I looked on my drive. over the last years I used "only" 800 GB in 1 year... I shoot a lot and for the moment didn't delete more than 5 % of the raw Why? Disk space is sheap I can probably delete more than 50 % and why not 80 % of the picture but it take time and i don't have time for that.

Hi @Muellema Ok I understand... sometimes you got the "wrong" item... in this case :( In France we say "a monday car" if you have with a new car a lonnnnggggg list of problems... you got a "monday strobe" I realy hope that the 2 Max II I will receive are "good" items. But I agree if you have a lot of problem Retra should replace your strobe

I found you are realy negativ against the Retra strobes.. why ???

Thank you for the explanation. In the past I shooted with a canon G5x... I founded some limits. Ok it is now an old model That is why I moved for a R5 Main point no delay clic --> photo that change my life but you are absolutly right.. heavy, big etc... not very time the best choice. Perhaps in the futur I ll show a smaller solution to replace my "old one" R5.
