    I had some of these from their original pre-production, was and is an amazing product but had a little niggle with the magnets, it’s nice to see they have rectified this and the production ones are better than ever. Cannot recommend these enough. Awesome product and customer service.

    The only step-up ring anyone will ever need. I have one for each of my wide-angle lenses. Thank you ALTER!
