Some items like your keys or wallet you just take everywhere you go because you just never know. For anyone with an EOS R series camera, add the RF50mm F1.8 STM lens to that list. As part of the EOS R System, it’s nice and compact thanks to its RF mount so you can shoot – and get a great shot – anywhere and anytime. Size isn’t all though. As a fixed focal length lens, it lets you be creative with composition and can be used for a wide range of scenes from snapshots to portraits, landscapes to low-light situations and more. Those images will stand out, too, just like you intend whether on social media, or when sharing or printing, thanks to impressive optical features like a PMo aspherical lens to suppress aberrations, Super Spectra coating to reduce flaring and ghosting, and a large f/1.8 aperture for low-light shooting and beautiful bokeh. Pick it up and use it one time and you’ll see for yourself, and you won’t be able to leave the house without it.

Photographing Artwork and Paintings

Use this lens with the R7 camera in photographing artwork inside and outside. The clarity is excellent, and the aperture of 1.8 is outstanding. Even in very dark environments, the images are bright.

Sharp Inexpensive Prime

Bought my first entry level "real" camera (R100) on a whim during a Black Friday sale with two kit zoom lenses. After getting a chance to use it a bit, and really enjoying it taking it on vacation, I decided to try a few different lenses. This was the first additional lens I bought and first prime lens. So far I am really enjoying it. It really make the image quality step up from the basic kit lenses. I bought this as a refurbished unit right from Canon, so it made it even cheaper. The only thing that surprised me was how noticeably loud the auto focus is. Don't really notice it outdoors, but indoor in low light it does hunt around for focus a lot. It is loud enough to pic up on the microphone when recording video. I can feel the motor moving back and forth if I have it on and just walk through my house. I've had to override and focus manually a lot too. I do also find the 50mm focal length on a crop sensor camera a little too narrow to be the go to, all around length, especially indoors. I also bough a used 30mm prime from a 3rd party company, which is roughly about the 50mm full frame equivalent on a APS-C. That's what I leave on the camera as a default to get a quick pic around my house. I do like the 50mm better for walking around hiking though. It is also very compact to through in a travel bag.

Outstanding Lens

Quality Glass in a small package, technology came a long way. The new RF lenses are amazing; you don't have to buy L to get quality images anymore and I mean Quality. This lens is like having 2 in one, it captures a bit closer in the frame compared to the L and better at close ups also. From around F3 things get super sharper.
