I bought this lens after my stock lens (Canon 18-55mm f/3.5-5.6) broke. I have been using this lens for quite a while now and I am pretty satisfied with the images and their qualities on a 6.3Mp Canon EOS Digital Rebel. I've taken this lens to many places I have visited and it has coped up well.
The disadvantages (as per me) of this lens are:
1) Changing focal lengths is quite a hard task as the rotating barrel is not easy to rotate.
2) The AutoFocus mechanism of this lens is quite noisy. It ...

I used this lens most of the time. the most important point is the ability to zoom 18-200mm, an enormous upgrade from a kitlens, which is only 18-55. like kitlens, you can use this lens for any condition. landscape, potrait, telephoto, and even macro. of course, the image cannot be compared to specialized lenses like ultra wide or 400mm, but the versatility is what counts. and it's very light also. for around Rs15000 or so, this lens is perfect as the first lens you buy after kitlens.

I damanged by stock 18-55 lense on my cannon. Hence was looking for a replacment + some added value. This lense is great value for money. Sure its heavy, zooming in seems a bit tight, but picture quality is very good. Extra zoom is awesome if you are using it for the first time. However, in low light, you need a tripod or extra steady hands to take indoor pictures as well. Just got it yesterday so still trying to figure things out.

Opted for a 1 day delivery. for 90 bucks it was a very good ...

The Tamron AF 18-200 mm lens is an Excellent lens and compatible to my Canon 600 D.
Provides a good Zoom.
However at high Zoom, the shutter speed is very less, so the shutter remains open for a long time which might cause blurry images if the subject or the camera moves. This is normal for all Zoom lenses, not just Tamron.

So increase the ISO to 800 and above at high Zooms and set the shutter speed and Aperture accordingly to get great Pictures.

Use Tripod at High Zoom.

I owned a Fuji HS10 (30X zoom) and was delighted by the flexibility of composition i got with it.
When I moved to Nikon D5100, though I was loving the professional grade photos, I got bugged every time I had to change my lens. I was in the lookout for an all purpose lens which I can carry while traveling along with a 50mm prime.
I am more than satisfied with this lens. The little difference in clarity is negligible and cannot be distinguished with naked eye.
The DoF i get from lowest f numbe...

A great camera lens at this price.but i would like to buy a phone where i will get a discount at this Diwali like Panasonic is offering a great discount on phones as well as all electronics

PROs:
1. Build quality is good at this price.
2. Looks good with the golden ribbon.
3. Reasonably good image quality
4. Good bokeh on tele ranges.

CONs:
1. Lack of image stabilization. Images get affected at high zoom. One must remember the shutter speed to keep higher than reverse of the focal length.
2. Lens cap material does not seem to be well coated. After 2 months of use, i saw brownish rusting kind of layer on both sides of the cap.
3. In low light and high zoom situation, one have to...

The Tamaron lens 18-200 mm is an excellent partner for your camera. I leave it with the camera every time without bothering to interchange the other lenses as this one covers the range which a camera enthusiast needs. Especially it comes handy when you are traveling and can go light on the luggage.

The lens gives decent quality images and am very satisfied with it. I would recommend this lens to anyone who wants to buy a good lens and is on a budget.

I noticed that the lens had a mild fungus from within. Initially i thought its just the glare of light and I neglected. Within a few weeks of use I noticed that the fungus spread across the inner side of the lens. I called the up the service center which is the only service center in Mumbai at worli and it was pathetic just pathetic. I thought the south Indians are the most courteous lot across india but the owner of the service center failed to be that to the core. Very unhelpful Ass%^&* tha...
