Did you ever wonder what a Canon 5D Mark II looks like inside?

Probably you did, and you already got an idea of it from our previous article.

Now you can see the final part of the work, entirely performed in one working day by Patrick Tong (amazing, isn’t it?).

For an alternative way to use cine lenses that does NOT require modifying your beloved camera (thus avoiding the high risk of damaging it), check our comments below about the new Carl Zeiss cine lenses.



Obviously this surgical intervention requires the competence and skill of a professional.

After the modification the camera accepts 35mm PL mount cine lenses, but since the mirror is removed the only way to shoot still pictures is in Live View mode.

As we pointed out in our previous article, Patrick made an important comment: only 85mm/100mm/135mm cine lenses will work properly on the modified 5D Mark II, because the sensor is 36mm x 24mm (larger than the frame size used on cinematography cameras which use PL mount lens). Of course you can use any other PL mount lens too, but you will probably get some vignetting.

Unless you already have many cine lenses ready to use, you probably don’t want your camera to “suffer” this surgery, right? We understand. In such case the following information might be VERY interesting for you.


There is another solution to use cine lenses on your 5D Mark II or any other Canon DSLR with Full HD capabilities that does NOT require any modification to your camera: to use the new CP.2 cine lenses by Carl Zeiss.

It is a safe and very high quality option which has already been adopted by many filmmakers who make serious use of the 5D Mark II and other DSLRs with movie/video capabilities.

Lenses with interchangeable mount

From Carl Zeiss website: “The Compact Prime CP.2 lenses are the latest members of the ZEISS family of lenses for digital and film cameras. This second generation of the Compact Prime lenses now delivers even greater flexibility by introducing interchangeable mounts that allow the lenses to be used with a wide range of cameras from traditional cine to HDSLR systems.”

A very important note: “All Compact Prime CP.2 lenses cover the full-frame image format (24 x 36 mm), ANSI Super 35 and Normal 35 image format, except the CP.2 18mm/T3.6.”

For more technical information, please check the manufacturer’s website.
