![]() ![]() One of the things that really burned me about my nifty-fifty and EF 50 1.4 USM was heavy coma at larger apertures, rendering streetlights as blazing comets. Canon's Super Spectra Coating (SSC) update appears to be doing its job. On the other hand, wide open it's prone to flaring when a bright light is in the frame but almost flare-proof by F2.8. I wasn't inclined to use the CA sliders once even in high contrast situations. Periphery lights exhibit bloom and coma but improve as stopped down.Ĭhromatic aberration (CA) is nearly nonexistent with this lens. Ship at Dock | EOS 5D MKII & EF 50 1.8 STM at F2.0 | Coma is well controlled center frame even at F2.0. So although the optical formula is the same as the prior nifty-fifty, Canon's quality control went up a notch with this lens (or I got a good one!). My old nifty-fifty wasn't usable wide open and didn't get decent until F2.8. On full frame, optimal sharpness across the frame falls between F5.6 and F8. Corners improve considerably by F2.8 and light falloff is gone by F4. On APS-C cameras-90D and Rebel-corner darkening and softness aren't noticeable since nearly half the image circle is cropped out. Wide open my sample is sharp center frame, sharper than old my nifty-fifty and EF 50 1.4 USM, but soft and dark (light falloff) in the periphery-perfect for dreamy portraits but not so great for landscapes and night skies. The EF 50 1.8 STM has the same optical design as the prior nifty-fifty, but with improved lens coatings and close focus ability. It also uses an odd filter size, 49mm, rather than 52 or 58mm common to most small Canon lenses.Ĭanon EF 50 1.8 STM | Photo courtesy Canon Inc. Although construction has improved, this is still a bare bones design: no image stabilization (IS) and lacking both distance scale and DOF markings. Improvements include metal mount, sturdier barrel and AF/MF switch, larger focus ring, grippy matte finish and stepping motor (STM). The EF 50 1.8 STM is slightly smaller and heavier than the prior model, the EF 50 1.8 II, aka nifty-fifty, but with significantly better build quality. It does not fit non-Canon cameras such as Pentax, Nikon, Fuji, etc. ![]() It will also work on EOS R and M series mirrorless cameras with a mount adapter. The EF 50 1.8 STM lens works on all Canon EOS DSLR cameras, both full frame and APS-C (1.6X), such as the EOS 6D and Rebel S元. Nu'uanu Valley | EOS 6D and EF 50 1.8 STM at F4.5 Here are my thoughts on Canon's humble EF 50 1.8 STM after a couple years of shooting. Plus, the smooth bokeh of a fast prime helps make portrait subjects pop. The fast aperture of a 50mm prime results in a bright viewfinder, another desirable trait for dim conditions. Zooms, in contrast, tend to have slow variable apertures and are heavy and bulky. Why buy a prime-single focal length lens-when most zooms include 50mm? Even the slowest 50mm primes feature apertures of F1.8 to 2.0, fast enough to shoot without flash in candle light, and yet are among the smallest lens designs.
