What lenses would you buy coming from Olympus OM-D E-M5?

I had a Canon T2i, and then moved to an Olympus OM-D E-M5 in 2012. When I had the Canon I mostly used the kit lens, and then bought the Sigma 30mm F1.4 and loved it. Money issues came up, and I'm trying to buy cheaper to have the most money I can get. Right now I feel like every penny counts, and I'm unsure on what I would do.

I just sold my OM-D E-M5 even though I really loved it. The main reason I sold it was because the lenses I want are pretty expensive. I came across a very good deal on a Canon SL1 with the 18-55mm STM, 55-250mm II, and 50mm F1.8 lenses and memory cards. I bought all that for less than what I sold the OM-D E-M5 kit. I consider myself a casual shooter, and just like to take random shots of what I want to remember. I've noticed though that I preferred wide angle, not very wide but around 24mm equivalent to full frame.

I've only had the Canon SL1 for one day, and I've already noticed how IBIS really helped me in keeping ISO low. It's very hard for me to have a sharp image at 1/25, but that's probably due to having the 50mm with no IS. On the OM-D I was able to shoot around 1/2.

I'm now debating on what I should do, and have thought about the following options and I feel like all of them are completely different:

1) Sell the 55-250mm and Canon 50mm F1.8 to help fund the Sigma 30mm.

2) Sell the 18-55mm STM, 55-250mm and 50mm and buy a constant aperture lens like the SIgma 17-50mm.

I'm not sure about wanting to sell the 18-55mm STM lens though as I've been reading many good comments about it in this forum. It would also allow me to have extra money to pay off my school.

Are there any fast wide primes that are cheap that are recommended among Canon users?

I like the idea of having a small camera, and I'm curious about the Canon 40mm. Would it be redundant to buy it if I have the SIgma 30mm? Which one has is better the 40mm or the 50mm F1.8? I know these questions is subjective, and only the shooter can answer these questions. I'm just wondering what others would do.

Here are some pictures I've taken to show what I shoot:

Okay. I'll try to help you.

Think about what you want to do. You have such a variety of images that are mostly wide angle, that I don't think you'll benefit from keeping your telephoto. Sell the 18-55 also to cover your new lens purchase. Both of the zoom lenses you own aren't really that good, which is why they don't have a good resale value. I would recommend that if you need to be money conscious, you get the 17-40 f/4L and that will upgrade your wide angle coverage, and be something you can continue to use when you upgrade to full frame like the 6D. You don't need IS at those focal lengths, just learn good hand holding technique.
