Reviews and Problems with Sigma 18-200mm F3.5-6.3 DC
Showing 1-10 of 19
Auto focus not great in lower light
19 November 2012
Summary: I purchased an "As New" offering which may have been part of the problem. This could have been a loser lens in the Sigma lottery that was returned. I will say it arrived meeting the Amazon requirements for As New. In the original packaging with warranty card, and in good physical condition. I purchased this to give me a faster lens for taking pictures of a show put on by a theater group my wife belongs to. Very quickly I ended up swapping it out to use my 18-55 kit lens.
Summary: Frankly, my testing methods were rather un-scientific however, I stand by my findings. I don't know if I got a bad instance of this lens or what but the overall image quality, in my opinion, was quite bad. I tested this on two bodies, a D40x and a brand new D5100. I tested it with and without the Optical stabilization function engaged. I tested it handheld, on and off a very sturdy tripod, in bright sun and low light.
Summary: I've just received my lens and I was a bit dissapointed that it's not a DC II as you could see in the product description. I didn't expect this considering that the product is shipped and sold by Amazon. This is the 18-200mm F3.5-6.3 DC which doesn't include OS (Optical Stabilizer Function - utilizes a built-in mechanism that compensates for camera shake) and HSM (Hyper-Sonic Motor- uses a motor driven by ultrasonic waves to provide a quiet, highspeed AF) Even when...
Summary: The sigma is a great price but I found it well worth paying extra for the optical stabilization of the Tamron pzd. This sigma is great if you do mostly tripod work but I missed many great photos since they were blurry when hand held especially inside or shutter speed less than 1/60.
Summary: Ok so I got this lens due to the zoom range. Its a great range to have one lens mounted on your camera the majority of the time. That would be nice if the lens would produce decent sharp pictures. I shoot outdoors all of the time in Phoenix AZ. For those of you who are not familiar with Phoenix it is a desert here. Never a lack of sunshine no matter what the season is. With that in mind I never have my shutter speed below 1/250.
Summary: in the advertisment it is shown that this lens will work perfectly with all kinds of nikon digital cameras but when i tried it with my d60 camera the auto focus did not work , so i gave it to a friend to sell it for me , after waiting for long time i was dissapointed .
Summary: I bought this lens originally for my Rebel XT to replace the Canon 28-135 IS That I found did not offer enough wide angle with the 1.6 crop. While I was happy to get some wide angles I have grown to dislike this lens. First this has been the walk around lens for the Rebel XT and then in the last 8 months the wife's XTi. It's biggest issue is it shows serious vignetting. EVERY PICTURE with a light or sky background needs to be edited in Camera RAW to correct this.
Pros: Small size - Large Zoom Range, Zoom Lock, Hood included
Cons: Slow noisy AF, Serious vignetting, Only acceptable sharpness, Poor exterior finish
Summary: Having used the Nikon 18-55 kit lens and Nikon 55-200 lens for over 2 years decided to invest in an travel lens to save me from changing lens frequently. After reading positive reviews for this Sigma 18-200 lens decided to buy it, but after a day I am returning it as I am not happy with the quality of the photographs taken with this lens. There is no sharpness to the photos at all even in broad day light with the camera showing the subject is in focus.
