Suffers from a lack of sharpness

Summary: As a landscape photographer, sharpness is irreplaceable. I am always on the look-out for a light lens that suits my backpacking and hiking needs - and this lens is not it! Realistically, I knew this lens would not perform like a prime lens or $1500 zoom lens. However, it is incredibly soft and that is a deal breaker for me. In comparing with my Nikon 16-85 and 70-300 on my Nikon D7100, images were notably softer across all focal lengths.
Summary: I bought this lens for my Nikon SLR and was very disappointed. The lens did not fit the camera correctly (I would get f-- for the f-stop) so no picture could be taken. I called Sigma and they said the only way to fix it was to ship the lens back to Sigma. They did not find anything wrong with the lens so they asked me to ship my camera to them to calibrate the camera to the lens. I was not happy because 1. shouldn't it already be calibrated if it is for a Nikon camera 2.
Summary: I'm not sure if the lens that I got was just defective or representative of the product as a whole. I will say that this lens is in the process of being returned and replaced with another brand. It was nice to think that one lens would answer all of my needs but there is a reason to go with a DSLR and that is the ability to change lenses for varying circumstances.
Summary: I purchased this lens to attach to a Nikon D-60 SLR camera. It was to be used in my many excursions with a travel/exchange group. This year we went to Turkey. At first I was satisfied with the lens but it commenced to give me camera errors that read sort of," Lens not fully attached to camera". To correct I locked the lens and tightened. This happened approximately 15-20 times in an eighteen day period. Also, the lens developed numerous spots.
Summary: After my Sigma broke, I got a Tamron version with similar specs but at cheaper price and for better value. In all honesty, the 18-200mm has an issue of introducing noise, and the locking mechanism is very rigid so you are likely to get it jammed. The barrel often requires a small nudge to get it to move. If I had to rate this product in comparison to the better value Tamron version, I would rate 4/10.
Summary: I thought that the other lenses that weren't Canon were of the same quality. Talked to many fotographers and all agreed. But NOT!! I get a much sharper picture with my original canon that with this Sigma lens. So... I am still using my old one and only when I have to zoom in far away I use the sigma. Bummer!
Summary: Normalerweise arbeite ich mit dem Sigma 17-70mm und einem alten Tokina 80-400. Das 18-200 sollte ein "Immerdrauf" sein, vor allem für das Filmen mit meiner Canon 550D. Positiv zu bemerken ist, das sich Zoom und Schärfering schön weich drehen lassen. Der Stabilisator arbeitet einwandfrei, der Autofokus ist mir zu ungenau, ich habe bei meinen Testbildern und Test-Filmclips immer manuell fokussiert.
Summary: Das Sigma ist bei mir an einer Canon 60D befestigt und fristet(e) sein Dasein nachts in einer Discothek. Das Einsatzgebiet sind 70% Bildaufnahmen, 30% Videoaufnahmen. Fotografiert wird im Prinzip bei ISO 800 / f3,5 mit Blitz. PRO: Pro an der Linse ist das Verhalten bei Videoaufnahmen. Gut, die Kamera dreht auf ISO 3200 hoch, ist aber für den Anwendungsfall ausreichend. Hier spielt das Objektiv den Brennweitenbereich sehr schön aus.
