UWA : Irix vs. Samyang vs. Takumar

[CarbonR]

First tests with all these lenses :



(no focus error for the Takumar : it was dirty in liveview too)



Considering these results (that confirm previous tests of Samyang vs. Takumar), I would say that if you are searching for the :
- best compromise all included and cheapest lens : Samyang 14/2.8
- best 14-15mm : Irix 15/2.4 (more constant than Samyang)
- best with unlimited budget : Irix 11 (widest) + 15 (brighter, filters)
- widest lens : Irix 11/4 validated for me
- best on Spotmatic : Takumar 15/3.5 (only lens available on M42)
- UWA with filter thread : Irix 15/2.4 (95mm filters)
- best construction quality : Takumar >> Samyang >> Irix (full metal >> plastic with smooth focusing ring >> all plastic with "plastic feeling/no feeling" focusing ring)

Note on Irix 11/4 : of course we can have better lens... but my specification sheet was to have the widest rectilinear lens in M42/K/EF mount for lets say, under 700 EUR.
The distorsion of the Laowa 15/4 is a no-go for me (if I have to process each picture, I can also take a fish-eye lens...)
The Laowa 12/2.8 zero-D is too expensive
Canon lenses are too expensive
Samyang XP lenses (10/3.5 and 14/2.4) are too expensive

Crazy but they all seem good to me.

That's why I prefer fields test done according to my pratice, rather than only relying on internet-test or persons that only have certitudes about lenses that they never touched
As I have the two Irix, I'll keep them some months to see what to do with them. Otherwise the Samyang would be the right choice for me.

BTW, the 15/2.4 will return to seller : its hood is not aligned with sensor, making shades in the images, and its chip says it is a 11/4 lens...
