By the way one consideration on housing is if there is any thought to adding a monitor as I think only aluminum housings accommodate the HDMI needed.

These plan view comparisons are really helpful for a sanity check! I handled/shot the Sony A7RVI in the Singapore airport and gave it a thought as it was a joy to hold and shoot (and FAST AF!), but the cost, weight, and bulk of lenses, ports, and housing sobered me right up!

I shot the 30 mm on two daylight dives by mistake (the hazards of assembling camera gear before coffee when jetlagged!) inside the 60mm port. Shots turned out amazingly well, although I wondered why my CMC 2 was so easy to shoot and seemingly lower mag than expected!🤯 I did not notice any creature spooking issues, but again I was unaware I was shooting the 30 until after the two morning dives when I pulled the camera for a battery swap so I wasn’t really looking for any difference. The 30 worked great on blackwater.

Davide, That is consistent with my findings—no complaints about image quality when it focused. I suspect it would be better on an OM-1 body, but not sure. The 45 on land seems decent for me—maybe a little slower than the 30 and 60–and even daytime dives the 45 wasn’t awful. On a blackwater dive it sucked. The 45 uses the same AOI port as the 30, but without manual focus capability. Evan

Chris, Thanks! The biggest issue I had initially with the 60 was getting too close as it has about 100mm min focal length. Once I got calibrated for set up it generally works ok for high contrast subjects. The biggest AF issues I had in Lembeh were 1) blackwater with the PL 45mm. The 30 mm wasn’t easy, but it focused much faster than the 45. The 45 produced some decent shots, but I missed a lot due to AF issues. 2) AF with the 60 or 45 on thin subjects—pipefish, whip coral with gobies, etc. This was amazingly frustrating as it didn’t seem what I was trying to do was that difficult. I’ll try to replicate the focus issues above water so I can compare the “gateway” EM10 to the M1. If the EM-1 mkii AF is just a little worse than the OM-1 ii I might move in that direction as I have a line on a used EM-1 ii with housing. Evan It was my first time, so I’m not sure, but I suspect so. I certainly didn’t hear any grousing about the visibility being worse than usual.

And expensive! I was surprised to see the number of people shooting Kraken monitors. Equally surprised that monitors now cost less than the 45 Nautical viewfinder.
