:EDIT: BTW: Nice Colors on those HIghspeed-Shots. TBH the first clip filmed on a chronos (which i have seen at least) where i realy like the colors and find them realistic. Did you do any fancy Editing Magic on that or is it just straight out of camera? :EDIT:
Hi Nikon1,

I used the Fujian Prime lens from the store and a Back-Bone Computar 1/2″ 8-48mm F1.2 6X Zoom C-Mount Lens. It produces that vignetting if it is zoomed out.
Hadn't enough space between action and camera so that i couldn't zoom in to see no vignetting...

Until now I have not found a solution to get rid of that problem :(
Ok, now that makes sense. I was wondering, if the 12,5-75mm Standard-Lens would vignett so badly on the Chronos...
But if that is just a 1/2" Lens, than this makes much more sense.
The only thing i know of, that would be realy wide and also "affordable" @230€ is this lens:
https://www.amazon.com/Azure-Photonics-AZURE-0614MLM-C-Mount-Megapixel/dp/B00OBMUSUK/ref=cm_cr_arp_d_product_top?ie=UTF8
Amazon and B&H are the only places i have found it yet for sale.
But i dont know if B&H ships their stuff to Germany.
Have never seen one sold used.
Should cover 1" completely while not beeing Fisheye.
I donīt have this Lens Yet, but that will be one of the next Lenses to get for my Nikon1 J5.
Or maybe try a Wide-Angle-Converter (Like 0,8x or 0,6x) and combine it with the 12,5-75.

Hi Nikon1,

I used the Fujian Prime lens from the store and a Back-Bone Computar 1/2″ 8-48mm F1.2 6X Zoom C-Mount Lens. It produces that vignetting if it is fully zoomed.
Hadn't enough space between action and camera so that i couldn't zoom in to see no vignetting...

Until now I have not found a solution to get rid of that problem :(
I did just remember that i had a 0,5x Wide-Angle-Converter lying around. i just tried it, and it would work great with the 12,5-75mm and the Chronos.
Pictuers attached to that post. Also pictures of the Converter itself.

Shot on the Nikon J5. The Red Frame Shows the Chronos-Sensor-Size.
Both Shot @ 12.5mm. The one With Converter is unfortunately out of focus by a little bit.
I dont think, that this will give you a real 6mm Focal length, but it makes the Lens quite a bit wider, while almost not vignetting.
For 16:9 it should be no problem at all.
.
Since i dont use it and since it would also most likely be not worth the effort to trying to sell that thing, i can offer to send it to you for free if you like it.

Pictures of Lens with vs Without Converter.
:EDIT: Sorry, seems my internet connection is too slow to upload the images of the Lens. :EDIT:

Quick RAW DNG test. Shot at 1500 fps. Edited in Lightroom for basic adjustments and added cropmarks in NLE.

I'm going to be at the Toronto Maker Festival this year so I have been compacting my demos for travel. I build a mini-ribbon speaker and it does some seriously weird stuff when over driven. The video shows both real time and Chrono-vision.

Nice! I'm planning to do similar shots but could not be bothered to set them up yet. Also those insects are fast!
