Hands-on video from CP+ here:
Sigma 50mm F1.4 DG HSM | ART
Thanks for posting, the lens looks good but a little big too! Still, it's quite yummie
"A flower shaped hood is unnecessary on a prime lens" Who is he kidding.
Yeh, I just posted this on one of the many other Sigma 50 threads there are going and this video has been posted to.
"As is normal with internet experts who have become popular via links, clicks, likes, and linked advertising, he makes several basic errors that are just noise, this, for me, means he loses any credibility.
First, if the lens is projecting a circle then a lens hood needs to be a circle, but if we are using a rectangular section of the projection, as we do in photography, then the petal hood is correct for primes, or a rectangle.
Second, more glass equals bigger T Stop, unless your glass has exceptionally higher transmission characteristics than your comparison. Though the loss is small, the more glass light goes through the less less light comes out the right end, that doesn't mean the Sigma is not an f1.4 but his use of T stop and glass is entirely inappropriate.
He is just repeating memes he doesn't understand and using popular terms in irrelevant contexts, which kinda makes the video an annoyance to me. "
