I purchased a Sigma 20-40mm 2.8 about 4 years ago, cost me around $300 AU. This is tack sharp and a great portrait lens on my K-3, will be an awesome UWA on a FF unit!

I bought a sigma 17-35mm f2.8-4.0. Im looking forward to using it on a full frame. Right now it works quite well as a wide to normal. I even bought a 82-77mm step down ring to not have to buy a filter size. No vignetting on crop.

Seeing the new 15 30 2.8 of tamron debunk the mythical 14 28 nikon image quality, I hope the new UWA Pentax follow the same directions.

Eager to try the 15mm 3.5 K in the future FF
