Small, great optics, great price

Great low-profile lens. AF/MF switch is nice to have, and the adjustable/assignable ring is a nice bonus on such a small and inexpensive lens. Have been using this mostly for landscapes but it does have decent bokeh when focused on closer objects. Sharp images and decent speed on autofocusing. Great speed in shipping from Crutchfield as always.

Pancake Deluxe

I bought the RF 28 2.8 STM, hoping it would make a nice lightweight walk around lens for my EOS R7. Indeed it's great: contrasty and sharp edge to edge wide open. It gets sightly sharper when stopped down, with optimal sharpness by F5.6. This pancake lens is so light it feels like I forgot to mount a lens-protrudes slightly more than a body cap. With APS-C cameras you can disable the lens profile in Lightroom and it still looks great (it's wider with profile disabled). I also tried it on my R6 MK II and while very good, the lens profile should be enabled to counter corner vignette. I estimate the uncorrected image is 25-26 mm but the profile crops the image to 28mm to nix the most of the vignette, brightens and stretches the corners and flattens the barreling. The result being, on full frame, corners are a little soft at F2.8 but sharp by F5.6. Compared with my RF 35 1.8 Macro IS STM, the 35mm is a level better along the periphery at F2.8 but, of course, is larger and more expensive. Wish Canon made a normal bayonet hood rather than the pricey filter-like screw in lens shade. All in all a perfect snapshot lens for the R7 and R10 and a decent lens for full frame if you don't mind computational corrections in PP.

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.

Our Listening Kit

To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. It’s available for a nominal rental fee, and includes a $25 Crutchfield merchandise credit.
