I have a Kowa 2x and it works very well with an Helios M44.
I used it with a navitar 50/0.95 and that is good too.
With a Kowa 2x, you can use some prime down to 35mm. I have the Carl zeiss 35/2.4 and it's not vignetting.
Could you please let me know where did you get the iscomorphot from ?
Thank you,
