"You better stop it ! You are going to cause me to buy a Rokinon 14mm f/2.8 lens. "
Actually, I use the cinema version of the lens 14mm T3.1. Same lens, but with a declicked aperture, marked as T values.
"Actually, I use the cinema version ..."
Does that indicate the QC is better, too?
It might. It might not. Who knows. I've bought three of them, and all three perform better than expected for the price.
I have purchased two of them, 14mm and 85mm, and both are very sharp when you get them dialed in. Another 14mm that i bought for my videographer son is pretty sharp, too. The 85mm is almost as sharp as my EF 24-105mm f/4L IS USM. It does show a little CA at the edges of the DOF, which can be easily removed.
If it looks like the Nikon, you might as well return it.
Yup, that's the EF mount. I have a cinema version of this 14mm lens. The shots I posted earlier were made with the lens focused at the hyperfocal distance. After a little trial and error, which means about a dozen shots, I found the hyperfocal setting on my lens.
Do you see the white bar next to the "3 m" mark on the distance scale. That is the reference mark. The lens seems to be focused at a distance of 3 meters, and is using a aperture that is between f/16 and f/22. The aperture ring is what it is. Dial in whatever aperture that you want to use, or need.
So,, where did I find the hyperfocal settings? Just "above" the 3 meter mark is an "L" shaped bar, that ends with the infinity mark. The entire length of the of the "L" represents infinity focus, or hyperfocal focus. Depending upon the nature of the ambient light, your hyperfocal distance can fall anywhere along that short reference line.
As it turns out, finding the hyperfocal setting in bright sunlight is pretty simple. Just use the "foot" of the "L" shaped mark that represents infinty focus. From that setting, I can adjust the DOF by dialing in different aperture settings. Most of the time for landscape shots I can use f/5.6 with a lens this short. With my 85mm, I seem to get better results at f/8,than f/5.6.
