I had reservations about buying this non genuine accessory but at the price it was worth a shot, however, I am very satisfied with this lenshood and it is quite sturdily constructed. I would recommend it.
When I first received this I though it would be too deep, and that there would be a "vignette" effect to the shots taken with it in place. Not so, because, unlike other lens hoods, it does not screw on to the end of the lens but, rather, has a bayonette fitting which attaches a little way down the lens, thus shortening its effective depth. It takes a little patience to fit (I found that one side would attach, but the other slide over the mount) but, when on properly it really looks quite good and works well. The quality of the plastic and the fitting is good and the only reason I did not give it a 5-star rating is because of the trouble I had (and this is probably only my clumsiness) getting the bayonette mount to go on evenly to both sides. Recommendable, nonetheless.
