I would suggest the Canon EF-S 24mm f/2.8 STM for street; it's pretty versatile on crop. Just be careful, f/2.8 is technically slower than the Canon EF 50mm f/1.8 STM for portraits...

Similar situation here—I found this combo worked best for my 80D: * Canon EF-S 24mm f/2.8 STM (street)
* Canon EF 50mm f/1.8 STM (portraits) The 24mm's 38mm equivalent FOV is way more versatile...

I have been shooting with EF mount bodies for over a decade and the 80D is an amazing piece of kit! If you want real performance on a budget, you should definitely check out these two options that often fly under the radar:

• Canon EF-S 35mm f/2.8 Macro IS STM: This lens is fantastic for street photography because the 35mm focal length is way more natural on a crop sensor than a 50mm. Plus, it has Image Stabilization which is a total lifesaver for handheld low light shots!
• Sigma 30mm f/1.4 DC HSM Art: If you can find this used, it is a total game changer for portraits and street. That f/1.4 aperture creates incredible bokeh that the cheaper f/2.8 lenses just cant match. tbh its basically a pro-level lens at a student price if you shop around on the used market. Getting a used Sigma Art lens is probably the smartest move you can make for pure image quality. The build quality is lightyears ahead of those basic plastic lenses. Youre gonna love how sharp your photos look with these!

Seconding the recommendation above!
- Canon EF-S 24mm f/2.8 STM: wider for street.
- Canon EF 50mm f/1.8 STM: better bokeh.
Ngl, u reallyyy need both for that 80D kit!

Building on the earlier suggestion, I have found that navigating the budget prime market requires a bit of a methodical approach. In my experience, there are two specific lenses that often get ignored but provide exceptional value for an 80D user looking for that professional look.

• Canon EF 40mm f/2.8 STM: This is a fantastic in-between focal length. It is sharper than the 50mm wide open and incredibly compact. It works well for street shots where you want a bit more reach without being too tight.
• Sigma 30mm f/1.4 EX DC HSM: You can frequently find the older non-Art version of this lens used for under $200. It offers a very natural field of view on crop sensors and that f/1.4 aperture is a massive step up for low light and bokeh compared to the pancake lenses. Over the years, I've tried many setups and honestly, these two offer a more professional rendering than some of the cheaper first-party options. Just be sure to check the used market... you can usually find great deals if you're patient enough to look.

Regarding what #4 said about Tbh, from a market research standpoint, you realy... it reminds me of when I was first building my kit. I actually tried out a Yongnuo 35mm f/2 for Canon EF to save a few bucks, but the autofocus was a bit of a nightmare. I ended up feeling way more satisfied once I swapped it for genuine Canon glass. If you want to stay under budget, my advice is to look at the used market. I've been shooting with these for years and you can usually find these two for a steal:

• Canon EF-S 24mm f/2.8 STM: Its so small and works well for almost any street scene. I take it everywhere.
• Canon EF 50mm f/1.8 STM: This is the classic for a reason. Great bokeh for portraits and it just works. Honestly, sticking with the native lenses saves you so much frustration in the long run. I havent had any complaints since I stopped messing with third-party budget brands for my 80D. Its just more reliable gear and you can easily find both used for under your total budget... just gotta hunt a bit on the usual gear sites.

Tbh, from a market research standpoint, you realy have to weigh the risk vs. reward when lookin at third-party glass versus first-party options. I've seen way too many people get burned by AF inconsistencies or micro-jitter on some of the older third-party mounts when used on a body like the 80D. Canon is basicly the industry standard for a reason—their optics are designed specifically for the proprietary EF communication protocol, which is why their glass is so reliable for street work where you need that fast lock. If youre on a budget and need to ensure long-term stability, sticking with the main brand is almost always the safer bet for reliability and resale value. Some of the budget-friendly third-party stuff might look good on paper with wider apertures, but the quality control can be a bit hit or miss compared to the manufacturer's own standards. Honestly, just go with any of the first-party options designed for your sensor size to avoid any weird electronic glitches... it's just more stable in the long run and gives you better peace of mind regarding the autofocus accuracy.

Just catching up on this thread and honestly, it reminds me of how frustrated I felt when I first started with my Canon EOS 80D. I spent a chunk of my savings on a lens that everyone said was a budget miracle, but it was such a disappointment in practice.

• the autofocus was so loud it actually startled people during street shots
• it felt like I was fighting the glass just to get a sharp image
• the view was way too tight for the narrow sidewalks in my city I really regret not thinking about how the crop sensor changes things before committing. I was so focused on getting a fast aperture that I ignored how clunky the motor actually was to use. I ended up missing so many shots because it just wouldnt lock focus in time. It definitely taught me that sometimes a bargain isnt really a bargain if it makes you want to leave your camera at home... I finally moved on to a different setup eventually and the difference in my motivation was night and day.
