While a 35mm focal length on an APS-C camera gives a wider view than a 50mm focal length... NEITHER is a "wide angle lens" on APS-C.

When used on a Canon APS-C camera (1.6X lens factor)....

... 50mm lens is a short telephoto (a nice "portrait" length with angle of view similar to 80mm on full frame or a 35mm film camera).

... 35mm lens is a very short telephoto or "slightly long" normal lens (equiv. to approx. 56mm on full frame/35mm film camera).

If the original poster's ONLY lens is a 50mm, I'd suggest something a little wider... such as 28mm or 24mm lens. There just isn't all that much difference between 35mm and 50mm lenses.

If the original poster specifically wants a "normal" lens, then the most ideal on Canon APS-C camera would be a 31.25mm lens... but no one makes one. The Sigma 30mm f/1.4 comes pretty close, but is a rather heavy lens. The Canon EF 28mm f/1.8 gives very close to the same angle of view on APS-C, acts as a "slightly wide" normal, costs about the same as the Sigma, but weighs about 1/3 less and is slightly more compact. Or, a super compact, ultra light weight, low cost option is the Canon EF-S 24mm f/2.8 STM "Pancake" lens.

While I agree the difference between a 50mm angle of view and a 35mm angle of view is not huge, the value of one over the other, as in almost all things photographic, depends on what you shoot. I find I rarely use my Canon 50mm f/1.8 STM on my Canon 7D Mark II because the focal length is too long for my general use.The prime I use most is my Canon 35mm f/2 IS USM, which is just wide enough for my purposes and has IS to boot. It sits on my camera around 50% of the time, the 50mm 5% of the time, and the rest of the time by various slow and fast zooms.

Well yes and no.... Not so sure that is how it works, but I will agree, it is definitely a 10-18mm even on a APS-C camera, now angle of view......

Pros are it is a great lens.
Cons are that it works like a 56mm lens on your camera.
If you want the near 35mm view then get a 24mm lens. FF will work just fine.

Good morning Bill I don’t know if this was mentioned you could look at the Canon 24-105mm f4 L lens ver1 for under $500.00 it’s a great lens I own one it’s wide on the short end and on the long end it’s a medium zoom it’s my walk a round lens on my Canon 7D. Remember it uses the center part of the lens it’s very sharp to.

Cutting to the chase, get an 18-135 lens. Will cover 90% of your photo situations. My one note song again!

Canon Crop Sensor cameras like your Canon T6i can use both EF-S lenses or the Full Frame EF lenses. However, should you decide in the future to buy a Canon Full Frame Camera, the EF-S lenses won't work. And the EF-S you purchased for your T6i will have to all be replaced. I have a Canon T5i and aside from the kit lens that came with it, a EF-S 18-55mm. I'm trying my best to buy all EF lenses for it, so when and if I add a Canon Full Frame camera to my arsenal I won't have to buy new lenses. This isn't easy for me to do, because EF lenses are more expensive than the EF-S lenses. Some would say buy Tamron or Sigma equivalent lenses. I do not agree that they are as good as Canon lenses. Canon is not expensive for no good reason. The glass in Canon lenses are superb!!!!! "That's my story and I'm sticking to it regardless to what anyone else has to say about it." Superb I tell You! Superb!
