There is a term that many older people use "You get what you pay for", and in this case it's true especially when using this lens with the Nex-7. There is a lot of purple fringing or axial chromatic aberration. This happens when the colours don't meet up in the same plane. This isn't something that happens with cheap lenses, the more known brands have this too. Nowadays this isn't something to worry about because it is easily removed in LR, you just have to be on the lookout for it in your images. However I had to remove the CA from a lot of the images on this outing because the weather wasn't all that good, the sky being rather grey so that a lot of edges had a light background. This is when CA might be visible especially when photographing leaves etc against a lighter sky.
It's not the sharpest lens I have but they do sharpen up nicely in post processing and even with these low res images you can see what I mean. There isn't a lot of sharpening done but you have apply some to all images. Focusing on the Nex-7 was quite quick, but then the Nex-7 isn't the fastest focusing camera on the planet. You can't compare it to the Olympus OM-D of Panasonic G5 for instance but it's fast enough for me with my subjects. It isn't the quietest lens when focusing either, not having a micro motor inside but you don't notice the noise after a while. You just get used to it like everything else. Well I did anyway. There is not a lot of hunting going on and it locked focus at the first attempt with 99% of my shots.
I tend to see my world through a zoom lens, which is why I have a lot of problems using wide angle lenses so most of the images I took were at the longer end of the zoom. I did however try to get some at the shorter end because I wanted to test all focal lengths of the lens. I do like prime lenses, they do in my mind, have better image quality (especially when it comes to low priced zoom lenses) but I just hate changing lenses. If I'm going out with primes I have at least 2 cameras with me, one with a relatively short focal length and one with a 100 or 135 lens attached.
