This past Monday I picked up the new Canon 40mm EF f/2.8 STM Lens which is the smallest lens from Canon. When I first heard about this lens, I didn’t plan on buying it because the specifications on it were nothing I really needed due to my current lens armory. The 40mm isn’t a focus length I need as I already have a 35mm L and a 50mm f/1.8 both of which have a much wider aperture. When it comes to primes, no one would buy such a short focal with a f/2.8. Aside from its small size, there’s nothing impressive about it especially since it cost twice as much as the Canon 50mm EF f/1.8 which is the general same focus range, a much wider aperture, and slightly larger.
With the two side by side, the size isn’t really that much of a difference, but I can say the build quality is rather nice compared to the plastic-y 50mm. The 50mm is know to have a loud plastic gear wind when auto focusing, but the 40mm is pretty loud with its electronic AF. Also on the topic of AF, the 40mm is pretty slow even though the new MF designed for video is rather nice. This lens was designed for video use, but the features only work with one camera and most videographers would use MF anyways and probably stick with a lens with IS (image stabilization).
After having it sit around for a couple days, I had to take it out for a test run and see how it performs. Coincidentally, a couple of my friends mentioned there was a local car gathering at an old location and stopped by to try of the lens. There was a surprising amount of people there because it looked like this meet was dying for the past several months. This set was shot at night with no tripod and only the 40mm lens.
After the meet, I went to Studio Diner with a couple friend for some late night food.
