Excerpt: First off, I was very excited when I purchased this lens. My photography instructor advised me against buying this, but I did not listen. I did get some really cool shots with it. However, the auto focus was really horrible. It could never seem to lock in and focus on anything, and when it did it was very finicky (sp) and took forever to find a focus.
Cons: Breakable and cheap, Cannot focus, Difficult to Clean, Poorly made, Slow Focus, Weak Casing
Excerpt: I thought a fast prime lens for [$] was a great deal, but I am disappointed. Poor build quality, images not sharp. Worst thing is that the plastic mount is bad, my A-65 consistently did not recognize the lens. I am returning the lens.
Summary: This lens is ok, but a bit of a money waste, its really useless with the set zoom of 50mm, its not close enough in some cases and its too close in other cases.. if it had atleast a zoom of 18-50mm with f/1.8 then it would be well worth the money. plus the lens it self looks unprofessional and cheesy looking..
Pros: its nice that its a 1.8..
Cons: 50mm set is not great, and 1.8 is not low enough
Summary: Habe mir das Objektiv Mitte 2012 gekauft, an einer Alpha 580 und an einer Alpha 200 betrieben und war bis gestern mehr als zufrieden ... gestochen scharfe Bilder auch im Dämmerlicht ... unglaublich schöne Farbtiefe ... super schneller Autofokus ... der manuelle Fokus ist nicht so leicht handhabbar, aber sei es drum ... nur dann das, was bei mir leider in den letzten zwei Jahren nun schon zum dritten mal passiert ist: Die Autofokusmechanik hat sich varabschiedet ...
