Waiting for the maximum of the Perseids 2021 meteor shower it's a good time to ask which lens is best for capturing the Perseids with just one camera.

I have Sony A7R3

Samyang 8mm f2.8

Samyang 12mm f2

Samyang 24mm f1.4

Samyang 85mm f1.4

Nikkor 14mm f2.8

My guess would be Samyang 24mm f1.4 stopped down a bit to f2

See Figure 3 here: Meteor Photography which uses the stellar magnitude distribution of the Perseids to show the relative numbers of meteors recorded as a function of focal length and aperture. Tops are 24 and 35 mm at f/1.4. So, given your lenses, I would choose the 24 mm and use it wide open, because if you stop down to f/2 you'll miss about half the meteors.

For more interesting meteors with deep sky objects, I would choose the 85 mm f/1.4 and make images like Figure 5b on the above web page.

I plan, if the weather holds--not looking good, I'll do the following:

R5 + 105 f/1.4 on Fornax Lighttrack, 4K HDR 30 fps video

6d2 + 105 f/1.4 on astrotrac, 2K HD 30 fps video

90d + 35 mm f1.4 on astrotrac

6d2 + 35 mm f/1.4 on iOptron skytracker doing land + sky mosaic

7d2 + 24 mm f/1.4 on iOptron skytracker pro

7d + 15 mm f/2.8 timelapse

Wow, that's quit a nice line-up you've got there. Fingers crossed that the weather will turn out in your favour. Thanks for the answer btw, much appreciated.
