![]() ![]() For the price, it’s a wonderful portrait shooter and is capable of very sharp photos from about f/2.8 and higher. For most general daytime shooting, I would recommend this lens in a heartbeat. We expected this going into the review but still wanted to see what could be done using such a cheap lens, especially in the context of astrophotography. Performance and Image QualityĪs Canon’s cheapest prime lens, the EF 50mm f/1.8 STM is not Canon’s sharpest lens. It’s a simple photographic tool that fits its affordable price point. Other than the stepper motor focusing and the increase in aperture blades, there’s nothing particularly new or revolutionary about the 50mm STM. This is a barebones, budget friendly 50mm. It features a 49mm filter thread and a bayonet for the accessory ES-68 lens hood. ![]() The lens does not feature any kind of distance scale to indicate focus position. The lens does not feature internal focusing and instead uses a dated rack focus that moves all of the lens elements forward and backward when focusing. #Nifty fifty lens manualThe lens is focus-by-wire but feels very fast and linear, making manual focusing very easy and autofocus very quick. The lens features a simple AF/MF switch to flip between autofocus and manual focus modes. The lens uses Canon’s new STM stepper motor focusing system which is much quieter and faster than the old gear drive focusing system (but still not quite as silent as Canon’s USM ultrasonic motor focusing). The 7-bladed aperture will produce 14-pointed star bursts on point light sources when stopped down to a high f/number.įocusing with the Canon EF 50mm f/1.8 STM The lens does feature an updated aperture diaphragm with 7 curved blades that should keep out of focus highlights (bokeh) looking round at intermediate apertures (which is more desirable than the pentagon-shaped bokeh that the old lens produces). There is no mention of the use of any aspherical elements, so this seems to be a re-hash of their older design. The optical design seems very similar with 6 elements in 5 groups. The lens barrel is all plastic which keeps the lens very lightweight but still gives it a high quality feel. The new EF 50mm f/1.8 STM features a metallic mount, much preferable over the older plastic mount. This latest iteration of the lens is much improved in mechanical quality over its predecessor, the EF 50mm f/1.8 II. It’s a focal length that requires a little more care to use effectively, and I think that’s the reason that a 50mm is so often recommended as a must-have lens for any serious photographer’s kit.Ĭomparing the Canon EF 50mm f/1.8 STM with the EF 50mm f/1.8 II It’s narrow enough to force you to compose but wide enough to still use it practically for capturing a scene. I really like the 50mm focal length for “everyday” photography. ![]() It’s a very small and lightweight lens, making for a comfortable walk around kit with a standard field of view. The Canon EF 50mm f/1.8 STM is compatible with all Canon EOS DSLRs with the EF and EF-S mount.
