Micro 4:3 "Very" Wide Angle Rectilinear Lenses

[VidThreeNorth]

For a long time I was looking at wide angle lenses that went beyond 12mm on Micro 4:3 cameras. I bought the SLR Magic 8mm F4.0 lens and so far, I could not even complete proper testing because it arrived misadjusted for infinity focus.

Although testing still has not been completed, I can already see that its performance is not adequate for 4K video work or general still photography.

I eventually did complete the test at:]
"SLR Magic 8mm f/4.0 rectilinear lens for Micro 4:3 mount"

I have not done much research since I got that lens, but there are two products that appear to more worthwhile purchases, and I think both are reasonably well established. So I am linking a couple of videos of reviews for people looking into these products. Consider these as "starting points" if you are looking into them.

"Voigtlander Nocton 10.5mm f0.95"

I have not really looked for test articles. The reason is that I felt it was priced outside my range. So if you check around thoroughly, there is actually a chance that there is more good information "out there" that I missed.

Here is a lens test and review from ePhotozine.com:

The following is a sample video made on a GH4:

Olympus' 9-18 zoom isn't bad. It's relatively sharp and you have the flexibility of having a zoom lens. The wide primes that are rectilinear, like the Laowa, tend to be pricey.

I have a slight extra problem using the Yi=M1 for UHD video work. The high amount of sensor cropping makes it more critical than other cameras. Otherwise, yes, the 9-18 would be nice. . . .
