Hello

[JCW]

This is my first post, hope it works ok. I need some advice from folks who know about these things regarding choice of zoom lens. I have a Canon 400D with a Canon 90-300mm and a Tamron 18-250mm but am thinking seriously about acquiring a zoom with image stabilisation. The 2 I have in mind (and in budget) are the Tamron 18-275mm and the Sigma 18-250mm.
Does anyone have any advice or recommendations on which might be the better choice?

Hi JCW and welcome to the forum

I havent used either of those lenses but if you use the search facility, it may bring some info, if not, post a thread in the Talk Equipment section, that should get better attention for you

Happy shooting

Welcome to the forum. I am afraid that I don't have either of those lenses.
But I can say that I really rate Image Stabilisation at the longer focal lengths. I have the 400d, and the Canon 75-300 IS. The difference with IS off is amazing.

Welcome

My advice would be to get the Canon 18-200 IS. It is the best lens of the type you're after, plus it has one big advantage over rivals, as I'll explain.

The appeal of superzooms is obvious and they really do a pretty good job IMHO, all things considered. But they do have their drawbacks and in particular they all suffer from CA (chromatic aberration), vignetting (or peripheral illumination - darkened corners of the image) and distortion (straight lines at the edges appear curved).

Canon has a unqiue suite of applications in its DPP software which fixes all this with a set of custom corrections, and this really elevates the performance of some lenses to a level that would be impossible any other way, at any price. Especially the 18-200. You have this software free with your camera, but it will need upgrading to the latest version to get the full range of benefits. You can do that here http://web.canon.jp/imaging/dcp/firm-e/pssx1is/index.html

There's a good review of the 18-200 lens here, and a demo of DPP corrections at work
http://www.dpreview.com/lensreviews/canon_18-200_3p5-5p6_is_c16/page3.asp DPP only works with Canon lenses, and you have to shoot Raw to use it, but that's a small price to pay for the major boost in image quality that it gives you.
