Pros: very cheap, much value for the money, well built, surprisingly good image quality, usable wide open, good low light usability, good portrait lens, simple firmway update
Cons: first firmware versions had problems with exposure (at least with Nikon F mount), there is practically only one real weak point: the autofocus is something like a pain in the ass, you should prepare a coffee while waiting... maybe even not precise enough, but that did not yet happen very often to me, otherwise no real problems especially if the price is considered
Opinion: I bought that lens on the second hand market for 100 Euro, which is practically nothing... As far as I know it is an old Canon lens produced under doubtful conditions by a former make-to-order manufacturer of the great companies. The first firmware versions seem to be outdated, so it is important to upgrade. Which is easily possible by an usb port at the lens. You don't even need an extra dock device. After that necessary step the exposure works acceptably well. The results are astonishing good, especially for the prices and if you consider the fact, that the lens has been constructed by Canon in the Ninties. I think Gorbachev was still in office then...
The following opinions have been automatically translated with Google Translate.
Pros:Price, Sharpness, Slow but Precise Focus, Bokeh.
Cons:Autofocus slowness, flare
Opinion:After a short time from the purchase to almost every photo presents a very obvious and large whiteish halo in the center of the photos. I don't know if it's due to a flare or something inside the lens. Taken away from this, the sharpness is really impressive for what it costs. I recommend it to the amateur who wants to approach the portrait, but I advise the professional
Opinion:For what it costs, especially used, it is difficult to ask for more. Not bad for those who are fledgling and have no professional expectations. The focus is really poor, in conditions the low light I switched to manual mode. It produces some chromatic aberration, but nothing particularly disturbing. Once you make a habit of faults, a lens that is so bright can be useful.
Pros:Good clarity, inexpensive, pretty accurate maf
Cons:Maf slow
Opinion:I say that I used it a little, I had to do it because the autofocus has been locked a few times on infinite, so even in a manual, making focus impossible in both cases. RnThe maf is accurate without Micro-regulation in the room however is slow and with little effort to hook up. I have found the sharpness all the time open but I can not compare it to the original because I have never tried it. After a while again and after about a hundred shots my specimen was unreliable with my canon 7d.
Opinion:Good optical performance even at TA. rnMessa slow fire, inaccurate, hard to keep up and I also doubts on the reliability of this. rnAvuto gift, because I was no longer willing to buy, the price attractive, but I do not know what it's worth this used, but for sure very little. so for those who buy a best buy used, if only to try the focal ...
