Must have for a C70
This was part of a FREE giveaway when I purchased my C70 and man am I glad I got it. I have YEARS of EF-L glass at my studio and this makes it all worth keeping around.

A total game-changer.
A total game-changer. It definitely brings back the field of view and works wonderfully on the RED Komodo. You do have to be careful about making sure some older vintage lenses with protruding back elements will clear and not contact/rub the element. Fantastic design, light transmission, and minimal degradation of image.

Essential kit for the C70
This speed booster is an essential piece of my C70 kit. The $600 price point allows me to bridge to the RF mount while utilizing all my EF glass. PLUS it knocks my 2.8 down to a 1.8! My only know with this booster is...why is it NOT compatible with the R5/R6? Slam dunk if that were the case. In spite of that I am so happy with this adapter...totally worth every penny!

Works great on RED Komodo
Kind of pricey for what it is, but works great on RED Komodo. Love that it makes a full frame lens it?s true focal length on crop sensor like c70 or Komodo, but it also acts as a barrier to stop dust from reaching the sensor when changing lenses.

Excellent customer service along with products
Beyond the product itself, I have been delighted with every purchase I've made on this website due to the excellent customer service I receive. I have been a customer of Adorama now for over 8 years and cannot express how pleased I am with the professionalism of your staff in-store and on support chat. Excellent job!
As for the product, it is no surprise that Canon has engineered such a high quality product. I'm extremely happy with the performance of the adapter/mount, my EF lenses perform brilliantly on the Canon C70.

Pricey but well worth it!
As someone who uses a C200 and EF glass, this is a life saver and has helped me out in low light settings on my C70. I was nervous that the autofocus wouldn't be as efficient but I was proven wrong when using Canon Lens. When I would another brand lens however there seemed to be some lag but nothing I couldn't fix by changing some settings.
Overall well worth the buy. If you currently use EF lens and don't want to make the jump just yet to the new mount with lens, this will save you some cash!
