Using the great Sigma 30mm F1.4 for 6 years now, I was wishing for something a little sharper with less CA wide. Then I tried out this new Viltrox and it blew me away in every way. Only drawbacks in my eyes are size and AF performance (I hope for an update). Right now I'm conflicted about keeping it and selling my Sigma 30mm F1.4 or buying the Sigma 23mm F1.4 instead, completing my Sigma prime Quartet. As the 30mm is to narrow for my liking anyways and the 23mm is quite expensive here in Germany (550€) the Viltrox could be the perfect replacement for those two lenses. On the other hand the poor AF-performance outside of the middle of the frame of the Viltrox as well as the size and weight of this lens are quite annoying - the AF with the 30mm is right 99% of the time in every part of the frame and there is an appeal to its smaller and lighter form factor... What would you guys recommend? P.S.: I got the Viltrox with a huge discount for 425€.
@ferraz916 I did not realise that there was a new update. I just downloaded it and tried it quickly and the AF performance is hugely improved, at least on the level of the sigma. I returned the sigma and kept the Viltrox and I'm very happy with my decision! :)
I thought the same until I bought it and it is not as bad as people thought it would be...the 75mm though is another story...that one is heavy but for a specialize occasion.
