cheap/budget low aperature lenses?

requirments:
- focal length (ideally bellow 20mm)
- ideally around f2 or less?

the lens can be zoom or just a set range.
Its mostly for film purposes for low light condition.
I just need something that can fit a canon mount.

I have a 50mm f1.8 and sigma 17-70 f2.8-4. My 50mm is pretty good but not ideal on a crop body (T3i). 17-70 f2.8 is still doesn't produce enough exposure.


I know there has to be some cheaper/budget kind of lenses out there that can fit the canon body?
I would assume some older style lenses? I just don't know where to start looking and for what.

any recommendations would be great!

Sigma 20 f/1.8

I love mine. They're around $500 used, probably less. They also make a 24 and 28 f/1.8

Price range? Cheap is $100 to some and $500 to others. There are no zoom lenses that fast, most stop at f/2.8.

Sorry I should have specified that.

Around $200-$250 or ideally less.

This is something that I don't need but it would be helpful to have. Even If its a 20 year old lense but works that will be fine with me


Sigma 20 f/1.8 is still something I'll look into. Thanks!

What Tanker said. a fast, wide prime is not all that "cheap"

35mm f/2

50mm f/1.4

50mm f/1.8

85mm f/1.8

100mm f/2

That's about it really for relatively affordable fast glass, at least from the Canon side of the house. I'm not that knowledgeable on 3rd party primes.

I understand, I've seen the prices.

I just figured there are some brands out there with some older lenses that perhaps will suite my needs

20 f/1.8 sounds like a perfect match. It's a wonderful lens. Save up and get one. You WILL like it

Generally, fast primes get real expensive, once they start getting below~30mm. You might be able to find an old MF lens, but f/2 or faster for 20mm or wider is not going to fit your budget. Sorry to say, but even a 25-30 year old MF lens with those specs will probably top your budget.

Below 20mm less than f2 and less than $250? You have no options.

I'm curious, what are you taking of wide angles that needs such low DoF and high shutter speed?

Automotive videos during evening or night.
2.8 still is a bit underexposed at night.
2 or 1.8 should be perfect just like my 50mm is.

I'm going to do a bit of searching around or just look at the 20mm

what's your ISO set at?...may be easier to just bump that up...there's also a samyang 14mm f2.8...but that's also going to be about double your budget
