Thought I would make all aware, purchased in September 23, thought it was time (December 24) to check for any firmware updates, it’s appears I’ve missed two. Using my Mac OS Sequoia 15.1.1, I mount the lens on my Mac and I carry all the instructions as described but when I copy/drop the update into the DFU it's not uploading/replacing the firmware new for old. I contact Viltrox technical UK they instructed me to contact the supplier which is Viltrox! I then explained that this isn’t a supplier issue and more a technical issue, so they instructed me to contact Viltrox.com! Very very poor technical help as it’s clear there is some incompatibility issues with OS. So be aware.Update 30/12/2024, after attempting to download 01.05 utilising my USB C from my portable hard drive and low and behold the new file copied across and updated the firmware for the lens, so ensure you use a good quality high speed data lead.So now I’ve got this sorted I would give the lens 5 stars, as it’s good quality and brilliant value for money.

I highly recommend this lens! I am using it with Nikon Zf and works great!
