Hello, this is my first post here so forgive me if i am posting in the wrong spot.
I am currently looking to buy a fisheye for my Panasonic HC-X920 and have two options between wich i cant decide. Any help/recommendation is appreciated.
Because i am on a tight budget (80€ max) there are only two viable options that o found so far (ill attach pictures).
Number 1: a Baby Deathlense Opteka clone 43mm for 50€ from Aliexpress.

Number 2: a USED Raynox MX-3000 from a local website for used offers for 80€

I cant really estimate how good each of these lenses will work on my Panasonic HC-X920. The filter size on the Pana is 49 mm so 6mm wider than the Opteka clone. And the mx-3000 is wider than the filter on the Pana (58mm).
My fear with the Opteka Clone is that it will have too much vignetting because its smaller than the filter on the X920.
For the MX-3000 i cant really estimate how good itll work on my cam because i didnt find a lot about it online. Is it comparable to similar sized Opteka clones?
Any Help/Tips/Recommendations are appreciated.
