Prime or zoom.

[RTX 3070 I7 11800h]

Hello, I need help deciding if a sigma 18-35 would be more beneficial then having a 35mm f1.4 and 20 f1.4 The only selling factor so far of the primes is less distortion amongst other things. What do you recommend? Also is there a huge difference in 1.4 and 1.8?

Use case? System?

 

If stills, distortion is correctable easily. I don't know if the same can be said for video.

 

f/1.4 to 1.8 optically is like a half or 2/3 stop. So not massive. But in design it is a bigger challenge to make a good 1.4, so pricing tends to differ significantly between them.

In terms of picture quality, prime lenses are better. F1.4 and F1.8 is <1 stop, so not much difference.

But you have a lens already that covers this focal range. Are you in need of the extra light?

One other big difference between the 18-35 and the primes you listed is full frame support. The 18-35 is a asp-c lens, so it will look like a circle on a full frame camera.

 

Is this for handheld video? If so, Id try to get a lens with IS if your body doesn't have ibis. Really lets you get much better hand held shots without a full rig. I can get pretty good handheld with no rig with IS on my camera.

yes. a 15-45 is f5 at 35mm which is way to dark and even at 18 which is f3.5? or f4? Also image quality is better on the 18-35 I recall from watching videos

Nope tripod use for alot of my video (80%)

and when I go handheld its for a short period of time. And I can handhold a 22mm f2.0 which is super light with barely and jitters that I can fix with warp stabilizer.

Canon m50 is not full frame

What ISO are you running at during video? 

 

The 18-35 is a better lens, but you probably won't notice the difference in most uses quality wise. Id focus on learning more than getting better gear.

IS in the body normally looks much better than stabilizers in post, and saves you time.

ISO varies and I will keep my eyes off products I have a huge problem ;-;

The m50 is a pretty good camera, better than what I did a lot of learning on(7d) and can make some good results. Id stop focusing on gear, and start focusing on what you make make with it, like story and composition. And the other parts of film making, like planning and coordination.

Primes also tend to have an advantage in weight, sharpness (for the price), and have faster apertures, which allows flexibility in the lighting conditions you can shoot. 
 

However, carrying additional lenses to cover what a desired Zoom would do can negate the weight savings of Primes. And in daylight, you seldom require fast apertures anyway.

so basically they have benefits to both.

Very much so. There are definitely some very sharp zooms out there as well, but those tend to cost a fair bit. 
 

It’s pretty much just a matter of picking the best tool for the job, your personal preferences, and your credit card limit.

Okay.
