I’ve been wanting to find an economy wide angle lens for Star trails….this one just might fit the bill. Thanks for the review!

Pretty cool lens 👍nice upload ☺

Can you use this lens on a 35mm film camera?

Nice review of that new IRIS. 15mm? That is good wide angle. I like the focus lock and infinity click. Coma and Vignetting is what keeps me out these lenses. I do however own 3 Rokinon lenses though!

How about wide open at f/2.4? Too much coma? Nice review.

Thanks. The coma is more apparent at f/2.4 though not massively so

I think you should stop looking at yourself on your cameras screen and look into the lens instead as it's rude to look away from the viewers while talking. BTW, this vid is now 3 years old and there quite a few other ultrawide angle lenses out there, and some are definitely better than the Irix...The Samyang XP 14mm f2.4 for example, which is only bested in aperture but not sharpness by the huge, heavy and stupidly expensive Sigma 14mm f1.8. The best budget 14mm f2.8 lens right now is the Chinse made Pergear, which got a fairly glowing review from lens reviewer Christopher Frost.

Your comments gave me the biggest laugh I've ever had reading comments 🤣 Thankyou so much for giving me such a giggle. I shown it to a number of people and they laughed too. 😄👍
