Summary: This lens is advertised as a Pentax "DA" lens, when in fact it is a "DA-L" lens: plastic attachment and parts vs. stainless steel as well as no quickshift focus and no lens hood. This amounts to false advertising for a cheaper quality lens sold as a higher quality counterpart. Buyer beware.
Summary: I was greatly anticipating trying this lens after all the stellar reviews. However, my lens was awful. I'm not knocking Pentax because my other lens is fantastic; I just received a bad one. When looking through the viewfinder, there was like a gray gauze across the entire lens and it was very dark.
Summary: First of all I am a retired professional photographer who has made a living from selling my photos for many decades, I'm not a Pentax basher or a Nikon or Canon lover, I assure you. I have owned and used many brands.
