Excerpt: Bought this today from a local store for £35. possibly overpaid slightly looking at ebay prices. It was an impulse purchase, so I didn't know what to expect. I took a few shots while on the school run and ran the RAW's thru CS6 when I got home.
Excerpt: I was surprised by the very good optical performance of this cheap manual focus lens, which I suspect is a stripped version of its autofocus F and FA 80-200mm siblings. In fact, the optical formula of all three lenses is identical (11 elements, 7 groups, 8 blade aperture).
Excerpt: I had no need to buy this, but when an eBay auction came up offering the FA 35-80mm f4-5.6, the FA 100-300 f4.7-5.8, and this lens together, curiosity got the better of me, and £43 including postage later I was the proud owner of all three. I apportioned this total to give the indicated price.
Pros: Light, sharp, good colour and contrast, across the full zoom range
Cons: Slow, narrow zoom range, and there are better (though maybe not as cheap as this!)
Excerpt: One of the first lenses I purchased when I was looking to play around with cheap. lower-end glass. I only paid a combined $35 (the seller also had it's littler brother, the 35-80) + shipping, and was pleasantly surprised when I received both lenses in almost new condition, complete with papers.
Pros: quick auto-focus, sharp enough, good color redering
Cons: physically unattractive, not fun for manual focus, not good for use with a CPL
Summary: I have this lens but was considering buying the current 55-300 Pentax offers to get more zoom for wildlife photography. While this lens is sharp with little artifact, the current crop of Pentax lenses were horrid.
