Are you aware that the lens aperture reported in the camera when using RS lenses is not accurate? The difference is greatest at the smallest aperture. For this reason I only use RS lenses in M exposure mode on Nikons. Clueless about use on Sony.

Nothing bothers me it is just very obvious when reviewing images in Lightroom and moving through them quickly in the 'filmstrip" or using arrow keys when they are taken with a stationary camera such as my salmon shoots in streams.

I can confirm that the Canon 8-15mm lens has focus breathing with concurrent change in angle of view.

We will just have to wait until the specs come out. Given its compatibility with many models it will likely be the same size as 4 AA batteries which does not suggest a super high capacity. Hopefully will at least equal 8 AAs. But upgrades will be possible.

Thanks. I am fairly nerdy with my pix - under the influence of my academic background.

4000 miles from the motherlode so grabbed a favorite from my website. 130° EMWL used to get this close up of a collector urchin, a common species in Hawaii but a challenge to get a decent shot of (ie., showing multiple details such as pedicellaria, tube feet, and spines). Taken off Waikiki where I made a pit stop en route to Palau.

EMWL - extended macro wide lens

Way more advanced than my video level. As well even posting v low rez versions takes many minutes even for a 30 sec vid. My net is very very slow for uploading.

OK figured out how to do the quote! Posting on facebok et al. even more important! Preaching to the choir if here.

Yes but it needs to wait until a get home. Meanwhile one can can look at pix in my techniques gallery. https://www.salmonography.com/Salmonid-Topic/Photography-techniques/ Many of these pix were previously posted on Wetpixel. The irony is that the internet is about an order of magnitude faster here (at sister's). Is there a way to post videos here? I know almost NOTHING about video. I used LR to edit and post the vids on my website via the LR smugmug app. All the recent ones there are done with my ipad that I have along to use with my Retras.

These time series images are priceless - having the dates on them especially. I think it is going to take a lot more of these to convince some politicians as well as the body politic.

I have used VEMCO acoustic tags in my past research. My guess is that the camera trap is triggered when a tagged fish swims by. BTW VEMCO had a diver-held receiver so one could visually confirm the tag was still in the live fish cf. in the stomach of a predator!! In my case I used stainless staples to suture the incision (where the tag was put in). The staple reflected a dive light rather nicely when we relocated the tagged fish while scuba diving.

I used the reflector on a single Retra (previous pro model) for most of my 105 shots from Palau in Feb 2023. Compared to many of the pix posted here I used slower shutter speeds to bring out more background. Because I am 4000 miles from the motherlode - I only have my website as reference. Many shots here https://www.salmonography.com/Marine-and-Freshwater-Biology/Palauan-fish-portraits/ There are some flashless shots as well as wide angle shots when I used a dome diffuser in this gallery. One can see a shadow in most of the reflector shots. One shadow looks more natural to me. The tiny circle with i in it will get you to the exif data.
