Pros and Cons
Canon EF 50mm f/1.8 II

Pros:

• Slightly better center sharpness (but this could be just my copies).
• Extends after focusing on close objects, but can be retracted when dismounted with the focus ring.
• Cheaper (in some markets)
• Lighter.

Cons:

• Bad corner sharpness at all apertures.
• Bad center sharpness, when shot wide open.
• Clearly visible aperture blade shapes at narrower apertures.
• Plastic mount.
• External focusing: Extends when focusing on close objects.
• Loud AF motor.
• Slow and sometimes inaccurate auto focus.

Canon EF 50mm f/1.8 STM
Pros:

• Much improved corner sharpness. Usable, even wide open.
• Overall improved sharpness when shot wide open.
• Better controlled chromatic aberrations, although still noticeable.
• Faster and more accurate auto focus.
• 7 aperture blades and new aperture blade design lead to nearly rounded bokeh lights, even at narrower apertures.
• Auto focus more silent.
• All-time manual focus override after half-pressing shutter.
• Lower minimum focusing distance: 0.35m instead of 0.45m.
• Metal mount.
• Thread for lens hood. Compatible lens hood ES-68 available. Lens hood with release button.
• Non-plastic feel.
• Overall better build quality.
• New lens cap design works better with lens hoods.
• Broader focus ring.
• Still very light and is a small lens that can stay in your bag.

Cons:

• Center sharpness and contrast not as good as the old EF 50mm II.
• External focusing: Extends when focusing on close objects. Cannot be manually retracted without power.
• Although the STM auto focus motor is more silent, it’s not as silent as you would expect it to be.
• Slightly more expensive in some markets.
• Notorious Canon issue: Lens hood sold separately and overpriced.

Saludos!

Y como si esto fuera poco ........ En este caso no se hizo la luz, ya que no hay ni como comparar un 1,4 con uno 1,8

Tenes razón Hacfoto, pero le consulté a mi bolsillo y me dijo que no, al menos por ahora.... Esa es unica la razón por la que no se hizo la luz...
