Which wide open lens with EOS C70?

[DuduBatumeli]

Hello everybody,

A question here about Canon C70.

I have RF lenses, such as 24-105, 16mm, 35mm, and 70-200. I have only 2 EF lenses: 24 - 105 and 24mm, 50 mm.

I need wide-open lenses. So, which best choices do you recommend on a modest, budget?

Thanks!

I am sure these all have different maximum apertures. What Aperture do you need? Is your 50mm the f/1.8 or f/1.2?

What is your specific budget?

One way to obtain extra light-gathering with your EF lenses is by use of Canon's 0.71x EF to RF adapter which works very well with the C70.  It won't change focal lengths, but it yields the same angle-of-view on the C70's Super 35 sensor as that lens would achieve on a full-frame sensor.  For light-gathering, it provides a full stop.

As an example, my EF 50mm f/1.2L with that adapter on my C70, and set to f/1.2, will gather light as if it was an f/0.9 lens.

The 0.71x adapter isn't cheap though ($600).

Also note that you'd need to weigh in other variables.  e.g. while the 0.71x adapter with 50mm f/1.2 lens is awesome at gathering light, that lens has no IS and thus the only IS you'd have without a rig (gimbal, etc.) would be to use the in-camera digital IS which can lead to issues for certain types of scenes.   If you're on a tripod doing mostly static shots, it's awesome.

Hi. The lens has f/1.8. But it is not about the aperture. I need wide-view images, landscapes, architecture, etc.

Hello,

I have the 0,71x adapter already. The lens I need is for landscapes, architecture, wide views of cities, nature, etc. So, I am in doubt, about which choice would be better: Tamron 15-30mm f/2.8 Di VC USD G2, Canon EF 11-24mm f/4L USM or Canon EF 16-35mm f/2.8l iii usm or 7artisans 12mm T2.9.

Appreciate your advise. Thank you very much beforehand

Canon EF 16-35mm f/2.8l iii usm its a L lens so it would work much better just multiply 16-35 times .71 and that would be your field of view 2.8 is faster and brighter light but the 11-24 canon f4 would be cheaper and even more wider but not sure how sharp it will be compared to the Canon EF 16-35mm f/2.8l iii usm the 16 would be about 11mm and the 11 would be about 8mm

Greetings,

Meike and Laowa both make some decent UWA & cinema series lenses.

While I always recommend canon first.  Its nice to have options.  The C70 is versatile and friendly to 3rd party glass.

S you don't want a "wide open" lens, you want a "wide angle" lens. All the advice has so far been wrong.

[DuduBatumeli]

So, in that case, which lens would you recommend?

One way to help deciding between lens choices is to rent them and see which will work best for you.
