We have a confession to make. Our reviewer is used to higher end DA and even premium DA* and Limited level glass. As such, it could be very easy to dismiss this Plastic Fantastic as sub-par from a build quality stand point.

I bought a K-3 simply because Nikon and Canon have never heard of "rain." all of the lenses I have with the K-3 are WR, weather resistant, so I decided that I really should have a couple of decent prime lenses that i could use, weather permitting.

Works perfectly on my Sony A7R II, in full frame mode, with adapter of course. This is a fullframe lens, and it's the best 35mm I've ever encountered, period. The photos produced are razor sharp from corner to corner, even wide open. I'm the most picky pixel-peeper, and I'm gushing with joy.

I wanted a prime lens for general shooting. I was a little worried that it wouldn't be as versatile as I needed, but after taking it along with 4 other lenses on a photo-heavy week long tour of Ireland, this was perhaps my used lens (if not, a close second).
