The new A7R VI will be an exciting new camera offering for those in the Sony universe and beyond. I have seen some speculation regarding the new battery, its size and if the new camera needed it to power the extra features and speed. We have seen battery upgrades for all manufactures over the years and why not if the camera runs more efficiently and with greater speed. The A7R VI comes not only with a new battery but also a notable up grade from the BIONZ XR (A7RV) to BIONZ XR2 Processor which would have been a speed boost without the new battery. The old battery and the new one are almost identical in size 52 X 22mm for the old and 52 X 23 for the new. In the photos you will see the big difference is that the old battery has the contacts on the wide side while the new battery has them on the end. So no big change in housing size only in placement of some controls.

The latest Apollo Y (GN22) has a manual and manual pre flash setting as well as RC, TTL, M-HSS and MTL for up to 10 FPS. Also has 3000 lumens white and 1000 red, uses two 21700 or 18650 batteries with much better speed and total flashes than AA's. The Pre-flash is also being added to Apollo III and Apollo S.

This is correct, the 17mm NA N100 to MX was actually designed for WACP C and the N120 20mm for N120 ports, extensions and wet lenses like WACP 1. I have used all of the above including WACP C, WACP 1, NA 230 dome and Matty Smith 12 inch domes with a verity of lenses. For macro it is best to switch to Marelux unless your macro port can convert using extensions. Attached photos are WACP-1 on N120 adapter, WACP-C on the N100 adapter and MS 12" dome on the NA N120 to MX adapter.

For underwater photography the $2800.00US 33mp Sony A7 V is the best full frame entry level camera in the market hands down. The best verity of U/W related lenses to select from at a wide range of price points, excellent AF speed, tracking speed and much more. Being able to use both the A7 V and the A7R VI in the same housing adds to the value as your needs grow. The housing supports FlashFuel 2100 for manual flash plus extra battery power, it also supports remote shutter trigger up to about 10 meters and has two M16 and one M24 mounts for accessories like vacuum, remote monitor, external USB -C charging, external flash triggers and more. Attached a few photos of the housing and excessories. US retail $3398.00. The housing can be ordered as an A7R VI or A7 V with kit for user conversion for use with both cameras.

Regarding housings for the new Sony A7R VI Marelux has developed a user installable (one) part change that will allow the A7R VI to be fully usable in the new Sony A7 V housing. This new housing ships with the latest updates which allow you to install the FlashFuel2100 which is both a manual flash trigger and battery bank which connects to the camera via USB-C greatly extending battery life. The FF2100 allows manual flash triggering up to 20FPS. The remote shutter module can also be added for remote camera triggering up to about 10 meters away. This housing retails for $3398.00 in the US. The upside to this housing is that with one part change you can have a 66.8MP primary camera with the excellent 33mp A7 V as a backup for extended travel.

My latest update on Marelux optics is that Aquista 135D will begin shipping in July, MacroView 60 will ship in June and the new 180 degree optical viewfinder has not yet been given a release date.

10mm would normally seem like an APS-C fisheye 1.5X=15mm 1.6X=16mm fisheye. If you look for reviews of the 7artisans 10mm FF fisheye it is 185 degrees and covers the full frame, it also gets very good reviews.

Not sure how 7Artisans came up with 10mm for full frame fisheye but they already have one that is MF and 185 degrees with minimum focus of 15cm.

Like with the release of the A1 II Sony is putting four years between the high end cameras so A1 users who passed on the A1 II will not be seeing an A1 III until their cameras are quite dated. That is not necessarily a bad thing many folks are still using DSLR's like D850 and EOS 5D. Having used Sony A1 and Sony A1 II extensively I can assure you that the II is an upgrade over the I for U/W users, the question is will that difference be enough to make you want to switch. Sony A7R V users will be in the same spot of deciding if the extra AF and shutter speeds along with a verity of other improvements outweighs the cost of a new body, housing and spare batteries. Sony is the top contender in the U/W space with four great contenders the A1 I/II, A7R V/VI, A7C II/R and the often overlooked A7 V an excellent camera at 33MP.
