14mm lenses are for the insane, or those who would like their images to look that way.

An impressive ultra wide-angle prime, the EF 14mm f/2.8L II USM is a Canon L-series lens well-suited for landscape, nature, and interior photography applications. Overall, this new lens performs so much better than the older 14mm L that it eliminates the need for correction in DxO. Cela permet d'éviter le flou en employant une vitesse d'obturation plus rapide. C'est un défaut de projection qui se traduit par un assombrissement des angles ou du centre de l'image.
For instance, Nikon uses a clumsy fake leather sock on their 14mm f/2.8, and a crappy plastic fall-off cap on their newest 14-24mm, neither of which is very good.This new 14/2.8 II lens uses an excellent snap-on plastic cap. Appareils testés: Nikon D7000 ou Canon 7D.
It locks onto the lens, and won't fall off unless you squeeze both opposing tabs towards each other at once. This new 14mm L II is still soft in the far corners, and greatly improved throughout most of the image over the previous The published MTF is excellent, far sharper in the corners than my original Canon 14mm f/2.8. (Since the digital nerds who spend too much time looking too closely at image files incentives Canon to bring the 14mm's performance up to levels which look OK on a 13MP camera, it looks super on film with just an 8xloupe. As expected, there's visible falloff at f/2.8, slight falloff at f/4, and none at f/5.6 and smaller.I'm greatly exaggerating this by shooting a white field; this is only visible with real images at f/2.8, and even then it's not annoying.
Nothing is said if the published graphs are monochromatic, polychromatic, or integrated over white light, so they mean very little for comparison to real samples of lenses. The only gotcha with the new cap is that it doesn't completely seal out dust, and because the insides are hard plastic, this cap will chafe the outer barrel of the 14mm lens with use.

This cap only goes on two ways. Alle Rechte vorbehalten.If you find this It's about the same as Of course these MTFs are dreams, which mean they are calculated, not measured from real lenses. It's invisible at normal and far distances, and has minor barrel distortion up close. This is a real flaw in the 14mm, and something I would consider very carefully.All this considered, and also considering that the the fixed 14mm costs almost double the price of the We know who we are. Don't lose sleep over any of this.You can use screw-in 82mm filters with the 16-35mm, but you can't with the 14mm. Un résultat de 0 est l'option idéale.
