Hey everyone! I finally made the jump from my smartphone to a real camera. I picked up a Canon EOS R10 a few months ago and I've been having a blast learning the ropes. I've mostly been using the kit 18-45mm lens that came in the box. While it's been great for learning the basics and taking some decent travel shots, I'm starting to hit a wall. I really struggle when I'm shooting indoors at family gatherings or trying to take photos during the blue hour when the light gets low.
I've been reading up on how to get that beautiful blurry background look for portraits, and everything points toward getting a prime lens. However, as a hobbyist on a pretty tight budget, I'm finding the lens market a bit intimidating. I know the RF-S mount is still relatively new, and while I can use full-frame RF lenses, I don't want to spend more on a lens than I did on the camera body itself!
I'm specifically looking for something under $350 that balances quality with portability. Here are a few things I'm looking for:
- Better low-light performance than my current f/4.5 kit lens.
- A focal length that is versatile enough for both street photography and portraits.
- Fast and reliable autofocus because I take a lot of photos of my dog who never sits still.
I've looked at the Canon RF 50mm f/1.8 STM because the price is amazing, but I'm worried it might feel a bit too tight on my APS-C sensor for everyday walk-around shots. I've also heard mixed things about using adapters for older EF lenses versus buying native RF glass. Are there any hidden gems from third-party manufacturers like Sigma or Meike that I should consider?
I'm really eager to step up my photography game but I want to make sure I'm making a smart investment. What do you think is the best budget-friendly prime lens for a Canon APS-C mirrorless setup right now?

Im a bit of a stickler for reliability so im curious about your dog—is he usually running around outside or mostly indoors? If hes a zoomie-type dog, autofocus speed is gonna be your biggest hurdle with budget glass. Id stick with native glass like the Canon RF 28mm f/2.8 STM for the warranty and peace of mind, but what kind of lighting are you usually working with when hes active?

Late to the party but I had this exact same dilemma when I started. I was really scared of third-party lenses like Meike because I didnt want to deal with weird focus glitches, tbh. I stuck with native glass for peace of mind. I compared two main ones before deciding:
- Canon RF 28mm f/2.8 STM: Its super tiny and the AF is basically instant. The f/2.8 is better than your kit lens, though maybe not enough for really dark rooms.
- Canon RF 35mm f/1.8 Macro IS STM: I found a refurbished one near your price range. It has stabilization which is a lifesaver. Its a 56mm equivalent, so its a great middle ground for portraits and street. Personally, I went with the 35mm because that f/1.8 really helps with low light and catching my pets!

I totally get why you are hesitant about that 50mm. On your R10, that 1.6x crop factor turns it into an 80mm equivalent, which is basically a dedicated portrait lens. If you are indoors, you will be backing into walls trying to fit people in the frame. Honestly, for your budget and needs, I would strongly recommend the Canon RF 28mm f/2.8 STM. It is a native lens, so the autofocus is going to be snappy enough to catch your dog, and because it is a pancake lens, it makes your R10 feel almost pocketable. At 28mm, you get a field of view that is roughly 45mm on your sensor, which is the sweet spot for walk-around street photography while still being useful for full-body or waist-up portraits. I generally advise against adapters when you are starting out. While EF lenses are cheap, the adapter adds bulk and can sometimes lead to slower communication between the lens and camera. For a beginner-intermediate setup, native RF glass is just more reliable. The f/2.8 aperture might not seem like a huge jump from f/4.5, but it actually lets in significantly more light and gives you a much cleaner look in those blue hour shots. Plus, the sharpness on this prime is way better than what you get from the kit zoom. It is a safe, high-quality investment that fits your budget perfectly.

I totally agree about sticking to native mounts for the best autofocus performance. Since youre budget conscious, definitely keep an eye on the Sigma 30mm f/1.4 DC DN Contemporary for Canon RF. It just launched for the R series and hits that sweet spot for street and portraits. If thats too pricey, look for a refurbished Canon RF 28mm f/2.8 STM on Canons site. Its honestly the best way to save money while keeping that native reliability.
