Here is a 100% crop at the corner. no MFO-1 With the MFO-1

Since there is so little posted pictures taken with an MFO-1, I thought I would share my experience. Here is the short story Canon R7 with RF100mm, 1/250 f18 iso 320 on all shots. All pictures unprocessed. without MFO-1 with MFO similar distance with MFO moved back to get similar size of subject compared to shot with no MFO-1 without MFO-1 100% crop with MFO-1 100% crop Now the long story. My main reason for buying the MFO-1 was to help focus hunting issues I was having when shooting fast moving fish like wrasses and in particular, flasher wrasse. I was very excited to find some flashers on my first dive with the MFO-1. I spent 30 minutes shooting them and did not see any noticeable improvement in focusing with the MFO-1. Many times I would preset a focus distance and when the flasher swam into focus, I would half depress the trigger and the camera would immediately go out of focus and hunt back and forth, just like it did without the MFO-1. I have had this problem ever since I got this camera a couple of years ago and even sent the camera back to Canon for repair but they did not find any issues.. The camera is awesome once it locks focus and works great on slow moving subjects. I was so disappointed I did not plan to use it again on my trip. After a couple of days, I thought it would be interesting to test the enhanced image quality the MFO-1 is suppose to provide. This is where something interesting happened. I started the dive with the MFO-1 attached to my flat port. When I took it off to shoot without it, I was shocked to see lots of air bubbles escape! Was I shooting through air on my first dive with the MFO-1? I did several shots with and without the MFO-1 to test image quality (picture above) then kept it on, excited to try shooting a wrasse without any air bubbles. No flashers but when shooting other wrasse, the same focus hunting problem occurred. I am not sure if my camera is causing the problem. I plan to send it back again to Canon again. So take my results with a grain of salt. Anyone want to buy an MFO-1 that was used for only on two dives? And just to show you I do know how to use a camera, this shot below was taken from my first dive with the MFO-1, maybe through an air pocket?

Maybe I am not understanding you but I was at the checkout screen where it asked for credit card info.

When I went to the check out screen, I did not see any tax. I live in the United States. Am I missing something? It seems to be a big improvement over the previous version. First the maxi and now this in such a short time. I have been waiting forever for the successor to the Inon Z-330!

Thanks for all the feedback! Since my housing is over 1.5 years old and has been on 15 dive trips, I decided I should remove the handles to check the condition of the screws. All screws came out easily and I did not see any corrosion. I forgot when I initially assembled my housing, I coated each screw with Ultra Tef-Gel, which prevents corrosion and seizing. It sure does work! I reapplied The Ultra Tef-Gel on the screws and now feel confident keeping the handles in place for maybe 2 years.

I know what the ideal thing to do is but I wanted to know what others actually do. I travel with both my handles on my Nauticam housing assembled. I never take them off. I know I should remove them after every trip and clean them but I worry about stripping the screws as they are so tiny. And also, I may be lazy:) What do others here do?

I can get through the day without ever worrying about changing the batteries but I heard from someone the power of the strobe may less with “old” batteries. I do notice on my Inon Z330, I am using them more on full power than I used to. Maybe it is my strobe and not the battery.

I have AA batteries that are rated at 2700 mAh. On my Powerex charger, it states all my batteries are around 2500 mAh. When do people replace their batteries?

After losing my vacuum cap twice, I have tethered it to my housing and never had a problem since. With both my DSLR and now mirrorless housing, I have been able so get vacuum by sucking air out my mouth. It sucks but it works!

Thanks to kallebumba, I made a handle strap and it was very easy! I felt the limited contact against the back of my hand would make it difficult to shoot one handed so I added part of an old camcorder strap and it seemed to provide more support. Now I just need to test it out underwater!

My trusty Xtar 18650 charger, after years of use, died. I was wondering charger people are using.

Moved over from Wetpixel. Switched from Canon 7D mark 2 to an R7 mainly for better auto focus which I now find is better at times but worst in certain situations.
