Recently I've moved from Final Cut Pro, to Adobe Premiere and now with Davinci Resolve. It's super powerful and I'm enjoying it. I just wonder, does anyone know of some intermediate to advanced tutorials or courses I can sign up for? I would love to really dive deeper (pun intended) in colour grading, dynamic KeyFrames, power windows panel, etc. I also find underwater videos quite different from land-based videos so most of the tutorials on YouTube are a bit hard to follow (land-based videos) What would I like to achieve? I would go up a few levels from basic colour grading like what I have here of some manta rays. I shoot with a Sony A7V, most of the time with slog3. Any recommendations welcomed!

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.

There are several factors: #1.: the prodruding element(s) of the Sony TC(s): the mechanical exception, i.e. TCs that work with almost any lens, are the Kenko TCs, that do not have such protruding elements. Native TCs (Sony, Canon EF, Canon RF, e.g.) have protruding elements that make it impossible to mount the TCs on most lenses, except the lenses for that the TCs have been designed for... #2.: The electronic communication of Sony TCs is often blocked by the firmware, even when the native TC fits mechanically, unless it is a lens that is approved by Sony to work with the native TCs... #3.: An exception is the arrangement Canon EF 8-15mm/Metabones V (Canon-EF to Sony FE)/Sony TC (1.4x or 2x), where the glassless adapter provides the space for the protruding element of the native TC(s) and the camera is communicating without problems with the TC/adapter/lens arrangement (It must be said, however, that this communication could potentially stop to work with any firmware update of the camera)... => It would be great in case it is possible to use the new AF fisheye lens with native Sony TCs, but it would be a very pleasant surprise for me in case it is possible (even if it is possible mechanically and electronically, there remains to be seen how the optical IQ is)...

Still no autofocus fisheye for APS-C Sony?

What makes you think you can't use the Sony TC?

A 10mm FF must be rectilinear, probably need a huge dome.

We were very happy with the image quality of the MFO-3. But we never tested the MFO-3 in combination with the 1.4 TC

Also looks like it is available for Pre-order including the dive case. Unfortunately it looks like the dive case has the same mediocre button on top, even though they made the one on the camera better. This top button has been the one reason I have looked at other housings, but never been willing to pay 20x for a housing simply for a better 'shutter' button. Hopefully the new one still works better! It is unclear from the post referenced above whether the user was just using the camera without housing to 20m (and liked the buttons) or was using it in the housing. Eagerly awaiting more underwater imagery from this camera.

If you want to measure what you really need in terms of powerbank, I would buy one of those USB-C charge monitor that inserts between power source and equipment. check the values on the screen of V, Amps, Watt when the camera is on and running. This will tell you the PD mode in place and amounts of watts needed. consider a powerbank that is able to deliver the same amount of watts (W) to its pins. Warning: between modes and phases (camera turning on, record starting), that can change. then consider the capacity of the powerbank (Wh) of the battery you need by deriving the number of mAh needed to cope with the PD mode which will set Amps and Volts to deliver the needed watts. You can also do something else: Consider the power the internal battery deliver : P = Vout x mAh = Wh Add a multiplier factor of P to the capacity (and time) you want to add up in extra to the battery Look for a powerbank of that capacity. The first method is probably more precise. The tricky thing is to think in terms of capacity (Wh) rather than fiddling with V and I as this is the principle of PD. The powerbank is doing the work to output power properly.

Some underwater shots from the Mission 1 - seems pretty good for no lights.

Obviously, I copy/pasted the wrong title to this ad. Will try to fix it.

Sold.

This is interesting... You say the Sony 2x TC will fit into the Laowa 8-15mm f/2.8 fisheye lens? In case it fits mechanically and electronically it will be very interesting to see photois made with Sony 1.4x and 2x TCs...

Hi, @Terri , As a Sony FF (a1) owner I can confirm the Canon 8-15 with either the Metabones IV or V or the Sigma MC-11 is a great option. I personally use the MC-11, but also own / use the Metabones V. For a TC I use the Kenko 1.4x attached to the 8-15 followed by the MC-11 connected to the body. In Nauticam world, this works well with the zoom gear designed for the TC. For most dives I prefer a water optic system such as the WACP-C (dry mount) or WWL-1B (wet mount) with the inexpensive Sony 28-60 lens. This gives up to a 130 degree FoV with a nice zoom range. The Canon 8-15 is what I use for those scenes that are a bit wider such as a massive wall, large view of a wreck, or inside a wreck when I do not mind a bit of the fisheye effect altering the vertical lines. Hope this helps! chip

Hi Chris, I'm based in Coffs Harbour, a fellow OM1 shooter!

As I wrote, I bet PD is completely unnecessary once you have rhe internal battery and you don't need a huge powerbank to double or triple runtime

The PCB board I linked earlier would fit with next to two 18650 batteries I believe. I say 18650 as this would leave space for a battery holder so you can pull them out and place them in a separate charger. two by 3600 mAhr 18650s would give you just about 26 Whr in capacity. Of course an off the shelf model would be simpler to hook up if you can get something close in capacity.the right size. This could be close: Cygnett powerbank It has PD so doesn't need a separate PCB it seems, does 9V 2.2A so not quite up to spec for solo running but should have plenty of capacity for you.

I remember on the LX100 I, I used to switch battery on every dive for video but more to make sure I don't run out of battery while diving.

Not much getting around it, occasionally you'll find an adapter second hand, I found one at about half price. You could wait and see on the Laowa newly announced but there maybe issues. If you have any interest in using it with the Sony 2x for an extremely flexible 180°diagonal fisheye that zooms to a 28mm lens equivalent in horizontal coverage then you need the I think the latest version as the Sony 2x nose will fit inside it. Requires a custom zoom gear printed which easy enough as designs are developed and available.

Actually you're right - I just realised that I was looking at only half of the picture: I actually have twice the size, with the other half of the housing, which is completely empty... I've tested again and if I remove the strobe trigger cable I can actually fit two 21700 batteries in there! 😆 One fits even with the cables still in place... wow I'll look into available mini powerbanks, see what exists with an interesting format, and test them with the camera when it finally arrives.

When used as it is, i.e. circular fisheye and/or 180° diagonal fisheye, it is certainly an advantage (in case optical IQ is o.k.). I see no way to use TCs, therefore still no substitute for Canon 8-15mm & adapter...

I see the Canon 8-15 with Metabones adapter is highly recommended with the Sony FF. Is this the way to go? Adapter is pricey. Thx
