F0.95 Lens For A Canon T4i?

CuriousPR

Hello, everyone.  This is literally my first post on here.  I’m a veritable newbie, have a Canon T4i, am preparing to shoot a short film, and am wondering what the lowest f-stop I can get for a lens that would fit my Canon would be.

I saw the film  “Upstream Color”, thought it was absolutely beautifully-shot, and read that it was filmed on a Panasonic GH2 w/a lens that was f0.95 (!).  I looked online and found a “7artisans 35mm f0.95”, and a “Meike 35mm f0.95, but I don’t know if those lenses can fit a Canon T4i.

Can they?  Does anyone know of any f0.95 lens(es) that can fit or be adapted to fit on my Canon T4i?

Thanks very much in advance for all the responses.

Cheers!  🙂

Neither of those brands of lenses would work with your camera.  There would need to be something capable of using an EF (or EF-S) mount.

The fastest aperture being sold by Canon today is f/1.2 (EF 50mm f/1.2 L and EF 85mm f/1.2 L).   You can potentially rent the Canon EF 50mm f/1.0, but do know that it would produce very soft images.

The fastest lens I have used is the 50mm f/1.2L.  When mounted to my EOS C70 via the 0.71x adapter, it will gather light as an f/0.9 lens (though for depth-of-field, it still remains an f/1.2).

Finally, do note that depending upon the distance to your subjects, capturing in such wide apertures can lead to extremely narrow depth-of-field.   The EF lenses I mention above also do not have any IS in them which could futher the challenges for video.

" Does anyone know of any f0.95 lens(es) that can fit or be adapted to fit on my Canon T4i?"

 

No and I suspect there never will be a sub f1 lens for any Rebel. The f-stop number is the ratio of the focal length of the lens to the size of the aperture. The size of the hole in the diaphragm will need to be larger than the diameter of the objective lens. What this means as you go sub f1 and start approaching f0, physics works against you until it becomes an impossibility. Long way around but Ricky is correct in the fact the lens would have serious problems with aberrations and distortion. Along with an extremely shallow DOF which would make focusing very difficult.

All this is just to advise you the stick with a lens in the f1.4 or f1.8 aperture range and to you will be much more successful and happy.

You made my day. 😊 It is an interesting topic and I just glossed over it in layman terms but hopefully got the main most point across.

Since the help I received from you and “re-eos” (Ricky), I’ve decided to pay another visit to a local camera store nearby and ask them some more questions - this time armed with a slight bit more knowledge thanks to the information you guys provided.

Does it look like this particular lens would fit my Canon t4i?

In the “Compatible Mountings” section, it says “Canon EF” and the t4i has an EF mount, no?

Yes, it would be compatible with your camera (EF mount).  However, two things:

  • Best to purchase equipment from reputable dealers.  Amazon is not the best place to get electronics.
  • The Rokinon 35mm f/1.4 lens is a manual focus only lens (no auto focus).
