I'm searching for a zoom lens in a range from about 20/30 - 70/90mm for my 5DIII. I like primes better and don't want to spend much on a zoom lens. I have no problem with manual focus or adapted lenses. I'm not a pixel peeper so the lens does't have to be ultra sharp when I look at the pictures at 100%. Important are nice colors, not too much CA (it should be removable with LR4/PS6) and the bokeh shouldn't be distracting.
If there is no lens that measures up to my expectations I'll probably end up with the Tamron 24-70. Oh god why. Again a 1000€ lens.
Have a nice day
