Since our inception as a company, we’ve modded hundreds of lenses and sold thousands more in parts and accessories to modify some of the world’s most sought-after vintage glass.  Through it all, our main objective has always been to empower end-users with knowledge and confidence to modify lenses as a DIY-friendly process.  We’ve taken great pride and joy in knowing that you could install your own follow focus gears using our SIMple Fit Aluminum Gears, convert native mounts to EF or PL using our SIM-Mount Conversion Kits, and of course, install our eye-catching front SIM-Rings and custom caps.  Making modding SIMple was, and will always be, our ethos.  And now, we’re doubling down on that commitment.


Simmod Lens will no longer offer lens modding as a service and will switch its operations to working solely on research, development, and launching to market new innovative-DIY solutions for our industry.


From the beginning, you’ve put your trust in our parts and services and helped build SIMMOD LENS to be the respected company it is today.  Now it’s time that we return that trust to you, our friends and customers, in equal measure. By focusing exclusively on DIY products and technology, we put the power and confidence of DIY into your hands as the simplest and most cost-effective way to mod your lenses.


In the coming days and months, we will transition our operations to realign and focus our resources on our new strategy.  If you currently have lenses in for service with us, we will work to get them modded and back to you as soon as we can.  


We are excited about forging this new path ahead and look forward to travelling down that road with you. If you have any questions, comments or concerns about our latest announcement, our products or anything DIY related, please feel free to drop us a line. We’d love to hear from you.



We're proud to work with some of the world's most trusted names in the industry to offer you the complete Simmodding experience.  All Approved Professional Network members use genuine Simmod Parts and are experts in the Simmodding process.  From Los Angeles to New Jersey, Western Australia, the UK, France, Greece, to the United Arab Emirates, we've got you covered.  Please contact one of our Approved Professional members below to discuss how they can help Simmod your lenses.

Video Camera Lens


SIMMOD LENS was founded in 2018 by award-winning cinematographer Ron Sim CSC with the mission of providing high-quality lens modding solutions for cine and video professionals and service providers.  Our goal was to make lens modification SIMple, affordable, and empowering for end-users to perform their own cine modding.  A lot has changed over the years.  Products have come and gone, but our mission remains the same.  We strive to provide the best possible solutions for today's cine professionals.  

We believe that a quality product offered at a fair price speaks for itself.  We don't dump money into fancy ways of convincing customers that they need to buy our products to be better at what they do.  Instead, we invest in researching and developing our ideas into better products with the thought that great products sell themselves.  

All Simmod Lens parts and accessories are designed, tested and approved at our Research and Development Centre  in Windsor, Ontario, Canada, before moving to final production at our high-precision fabrication facilities overseas.  Many of our products come with a lifetime warranty.  If something of ours breaks, we'll fix it or replace it.  It's as SIMple as that.
