Comparison of the Tamron 18-250: I was just curious if anyone had compared the Tamron 18-250 to the Sigma 18-200?

hi .. had the same choice to make.. but finally went with the sigma.. 50mm shorter but i think the OS capability will eventually make the sigma a more worthwhile purchase.. I live in Singapore.. Price for the tamron is about $750 and the sigma at $840 (singapore dollars). hope this helps

I had the old Sigma EF 500 Super and was pretty happy with it. Since I found I didn't really use the extra features of the Sigma Super, I replaced it with the 430EX II when it eventually died because the 430EX II had more than enough power, speed and features for my needs as well as being a bit sturdier than the Sigma. So I would say it depends on the whether you need the extra power and range of the Sigma. BTW, the Sigma EF 500 Super did have some quirks but I'm not sure they are relevant to the newer Sigma models.

Tamron AF 200-500mm f5.0-6.3 is sharper focus at the end of 500mm. This is the most important for bird wildlife photography and lighter. The Sigma 150-500mm f/5-6.3 is a stabilizes version. A little heavy. Also a little faster focus. What it really comes to is the photographer learning the little tricks each lens has to get use to. Both lenses are very well made in craftmanship.

Hi John, I've been researching this question for longer than is sane. It's easy to overwhelm yourself if you read every single (differing) opinion, which I have. I also considered the Sigma 18-250 but it's soft sample pics disappoint me. The comparison pictures on the following link made up my mind to go for the Canon over the Tamron http://www.juzaphoto.com/eng/articles/canon_18-200_sigma18-250_tamrom18-250_18-270.htm The other things include the indecisive AF on Tamron, this would frustrate me but would cause my wife to give up using it. I am convinced with fast moving kids and finding my favourite shots through an opportunistic eye that a superzoom is the way for me. If you set out to photograph a certain thing and aren't distracted by serendipity then multiple lens' might work for you.

The tamron is supposed to be good, but if you got the money, I'd suggest buying the canon. It is spectacular. The only thing I don't like about it is that the inner barrel is plastic, though I guess this is also true for the tamron.

I agree as well with the others. I own the Tamron and love the lens. Very sharp and works great for general use but the 50 I have heard is a great lens. If you don't mind using your feet instead of a zoom you should be good starting with the prime.

I don't know about the 18-250......a wider angle and a shorter telephoto. I have the 28-300 and have never needed a wider setting. Sigma makes a great product, you will be happy.

I purchased a Canon 60D recently and also purchased a Tamron 70-300 MM along with a Canon 18-135 MM lens. The Canon 18-135 lens is terrific! I took photos of the same subject using a Canon 18-135, the Tamron 70-300, and a Sigma 18-200 mm lens on the 60D camera. At full telephoto for all 3 lens, the Canon 18-135 was sharper than the Sigma and equaled the Tamron when I cropped the image down to the same size as the longer 300mm Tamron. I don't know if these results would hold true for all Canon bodies but it sure works for the 18 megapixel 60D. As an aside, the Tamron 70-300 mm with VC optical stability is a great lens too.

Good timing on your question, because DPReview.com JUST posted their review last week on that lens:http://www.dpreview.com/lensreviews/tamron_70-200_2p8_c16/Optically it appears to be quite good. AF is slow and noisy, but for 694 bucks at Amazon you can't beat the price if budget is a concern.

I have not had a chance to compare both but this sigma is the first non canon lens I have put in my bag. Have 6 different ones and the sigma is a great value. I have not regretted it.

Its really a budget decision. Both produce sharp images and good in low light, but with the sigma your packing more focal range without having to swap lenses.

There is some comparison which saying Canon 18-135 lense is sharper than Sigma 18-200. My frinds please Post Canon 18-135 or Canon 18-200. ( If both are from Canon. which is best).

The advantages that the Tamron 17-50 has over Canon 18-55 are it is faster by one f stop, much sharper, build quality is much better. The Tamron is the clear winner & is a nice affordable upgrade. The Canon 55-250 is sharp mid to telephoto a better match with the tamron 17-55 because of the sharpness. All the lenses are for crop sensors and are fully compatible the all Canon Rebel camera bodies.

Image quality is good ...but not better than my Pentax 55-300mm and 17- 70mm Lens, changing lenses is not easy in outdoor photography....so the Sigma 18-250 is very useful.

I have the D7000, 18-105, and 55-300 and the Tamron 2x converter works very well for me on them. I also have a Nikon 80-200 and it works very well on it as well. I love it. Gave me a great increase in focal length for a minimum outlay!

I have the exact same question. Please do post your findings. I am confused too. Apparently 18-200 is supposed to have larger zoom but I want to make sure that the quality of 18-200 matches to 18-135 at the least upto 135 mm. If so i will go with 18-200 for sure.

I have a 40D and plan a Europe trip with the intention of taking one lens, with the same choice. Questions are: Image quality at either end of the range? Macro quality, build quality? The utility of an additional 50mm of the Tamron?Critical perhaps is stabilisation with Sigma. Can anyone advise?
