Sample shots from Sigma 19mm F2.8 on Sony NEX-7
It has been very difficult to find a decent performing wide angles lens for the NEX-7. You can use an adapter and go with a big wide lens but that isn’t ideal if you want a compact solution. The rangefinder lenses have almost all shown magenta shift on the corners on the NEX-7 such as the Voigtlander 15mm and 12mm. Even the Sony 16mm F2.8 shows magenta shift and smearing at infinity in bigger apertures.
This is why it’s delightful when Sigma comes along out of nowhere with the lens equivalent of a double barrel shotgun. The Sigma 19mm and Sigma 30mm F2.8 lenses are both excellent lenses that are compact and high performing. What they give up on aperture speed they make up for in image quality.
The Sigma 19mm does show some CA but it’s very manageable and easily mostly removed with the auto chromatic aberration correction tool in Lightroom 4. It’s strength seems to be close up performance but it also does well at infinity. The colors are magnificent. At $200, this is a must buy lens especially right now with the shortage of good E-Mount lenses.
Here are some samples on the nex7, No saturation or vibrance added, except for 1 where it’s obvious.
The color separation and just fine detail close up is easily that of a $600 lens.
