Did you test also the Tamron 17-28mm? How is performabce against the Sony 16-25mm, if yes? Thanks, Wolfgang

Are you sure about the 140mm dome (I cannot find this dome as beeing compatible in the Nauticam charts)? What extension are you using? Would be great, one small domeport for both fisheye and rectilinear WA...

Domeport 180mm and Sony 16-35mm is not the perfect combination, 230mm domport, or, even better, Seacam PPO is the way to go (but this is not what CCRphoto asked for)... (Seacam wrote me that the excellent Sony 26-35mm GMII works very well with their PPO; flange distance in Seacm housing seems to be bigger compared to Nauticam, hence after doing appropriate recherches, Saga could make an adapter for Nauticam) But it may be useful still to state that it depends very much on a particular lens. Tamron 17-28mm works very well behind 180mm, even 170mm, domeport. Same with Sony 20-70mm. I can say this from my own experience, I use both lenses behind Zen DP170 with A7R5/Nauticam..

This is really a great resource to compare the different strobes. The reputation of Backscatter rised a lot on my personal scale...👍 I have a question on the circles in the test images: to wich angles of view do they correspond? Thanks, Wolfgang

Can anyone please check whether the Viltrox 2x TC is compatible with this new fisheye lens (I heared the prodrudingf element of the Viltrox TC is smaller compared to tjhe Sony TC)? Thanks, Wolfgang

PM sent... (I was out last week too, 9 days scubadiving in Kornati Islands 😊... returned just Yesterday )

I fear there is nor Kenko TC for Sony FE...

Yes

This, and other native Sony FE (zoom) fisheye lenses, look great, since they are smaller compared to the adapted Canon 8-15mm. The question to me is, however, whether they accept TCs and if yes, whether they provide acceptable IQ...

You say that this technology changes little for photography, but would it not be a hughe benefit against the blown out sunballs in WA photos?

I have never owned a MFO-1, but I am/was using adapted Canon 100mm IS macro/Sony 90mm macro/Sony 100mm macro on the Sony A7RV. Even with the adapted Canon 100mm macro AF was o.k, but a liga below the native lenses. AF is great both with Sony 90mm and Sony 100mm on this camera body, but there were several complaints that AF is slow/pumping on Sony A7RIV and downwards. AF may be even better with A7RVI and it should be on par with A7RV on the A7RC, but I did not use this camera ever... In the MFO-1 portchard (https://drive.google.com/file/d/1YcKS767I57nPedgq5vG3WVlElsp3XVLF/view) the Sony 28-60mm is not listed as compatible/tested, probably not useful for this lens (AF from the model A7RV upwards is very capable without any special diopters, however) I started by using the back LCD on my first UW camera, an Olympus EM5II (and previously the Panasonic TZ5 and Olympus EPL-7 from my wife). Upon upgrading to EM1II, I got a 45° viewfinder together with the second hand Nauticam housing. Since then I greatly enjoy using it (also now with Sony A7RV). It helps a lot in getting a slightly upwards from the bottom perspective without bending body and neck too much... I would not switch back to a plastic housing these days (e.g. like the initial Panasonic and Olympus housings of my wife, that I could use occasionally). My first alu housing (EM5II) was Nauticam (at this time very good quality (what is still the case) at a low price (unfortunately not valid any more)). Since then I use Nauticam. I presumably will not switch to Isotta or Marelux upon updating to a newer camera model, since (i) I know Nauticam as reliable and very ergonomic (I cannot say about the other brands, I never used one) and (ii) when switching to another brand I would have to deal with adapters for my other gear, i.e. (dome)ports, extensions, wetlenses, that is more expensive than just a bare housing ...

According to the Nauticam portcharts, the Sony 28-60mm behind Nauticam N100 45 flat port gives up to 0,9x magnification and working distances between 55-80mm with CMC-1, while CMC-2 gives up to 0,7x and distances of 83-135mm (https://drive.google.com/file/d/1caMOa2cyCxucdcAiI8q9UsUu1YEg9ImC/view) In addition, 28mm is probably the widest what one would want behind a flat port. (I use Sony 28-60mm behind WACP-C, but never used it behind a flat port and/or with diopters, so what I say is theoretical)...

Here is the assortment of different camera types that Sony offers, it seems pretty logical to me: #1.: Entry-level model class, very capable and universal: A7 Five generations exist at present, from original to mark 5 (A7V) #2.: Highest resolution and IQ, totally photocentric, not so good for video and fast action/sports: A7R At present in its sixth generation (A7RVI, which made a leap towards video and action, but still not the best for this purpose) #3.: High end allround model, high IQ for photo, fast action (e.g. birding) and good for video: A1 At present in its second generation (A1II) #4.: Specialized model series for fast action/sports: A9 Currently in its third generation, A9III, that has even global shutter (=zero rolling shutter and no limit to flash sync. speed) #5.: Compact series: A7C and A7CR Providing similar features as #1 (A7CII) and #2 (A7CR) in a compact camera body In addition they offer different types of camera bodies that are designed for videographers...
