The focal length of nifty fifty lenses translates to 80mm when attached to an APS-C camera such as the Canon 1200D. There are few croaked fifty dollars, while they are quite popular among amateur photographers, since cropped cameras can act as budget portrait and creative lenses. This lens makes the perfect gift to those relative newcomers to photography who would benefit from learning about the joys of a prime lens with a fast aperture.

It’s not too dissimilar to having a vintage 50mm lens, albeit with autofocus and without the weight of a metal shell.

We use Imatest SFR (spatial frequency response) charts and analysis software to plot lens resolution at the center of the image frame, corners and mid-point distances, across the range of aperture settings and, with zoom lenses, at four different focal lengths. Very important: During focusing to infinity, when the focusing ring is fully extended (with a slight overshoot beyond the 'infinity' mark itself), the mirror of full-frame cameras such as the Canon EOS 5D clings to the rear lens or the rear lens barrel.

Si je comprend bien le calcul de ratio, si je monte ce yongnuo 35mm sur mon sony a6000, ça revient à en faire un 50mm, donc, inutile si j’ai déjà le 50mm de la même marque? All this despite the fact that there are no problems with Canon's own fifty-kopeck piece (and with other lenses as well).

Not everyone will notice this feature and it does not particularly interfere with comfortable work with the lens.
