All round lens needed for 400D?

The latest super-zooms aren't that bad. Check out reviews over at www.photozone.de for more information. And this guy swares by the Sigma 18-200mm OS http://www.pbase.com/lightrules/lenstests

The Tamron 18-250mm is the best optically and is really rather good. However 250mm f/6.3 will need a fair amount of light to get sharp shots. The alternative is the Sigma 18-200mm OS which isn't quite as sharp, if you look at the photozone review, it kind of oscialtes from sharp to soft through the zoom range. However it does have OS and when I tried one out at a shop i was very impressed. Being able to go straight from 18 to 200mm in one turn is quite impressive and i was getting nice sharp images at 200mm 1/60th of a second which i was rather impressed with! The build quality of the sigma is also very good :)

A good alternative would be canons two new IS lenses, the 18-55mm IS and 55-200mm IS. They are both optically very good. They are also quite cheap, but the build quality is questionable...

p.s. I brought a Tamron 17-50mm F2.8....

Yup. None of the super-zooms, for want of a better term, have particularly good image quality and you're sacrificing f stops for the ease of only having one lens. You're trying to turn a dSLR, which purposefully has changeable lenses, into a point and shoot, which has one that does everything.


This is a silly argument, because part of the convenience of an SLR is being able to travel light with one lens if you want to. Why neuter the ability of the SLR to compete with the compact?

Got to agree these super zooms definately have a place in the SLR lens line up I can see them being really usefull on a back packing holiday or trecking when you've got everything you need to survive for a week strapped to you back the last thing you want is a few Extra Kg's of camera lenses.

I have a friend who has the sigma 18-200 OS and he has got some brilliant results, obviously it doesn't match up to a Canon L series but it is better than I expected and easily on a par with the bridge cameras I have used.

Don't think I'd ever have one as my only lens but I could see times when I would use one. Personally I have a Sigma 17-70 attached to my Camera as a walkabout lens and will probably get a 70-200 or 70-300 to give me a bit more reach.
 
Its i deal as a scout lens for my kind of photography were i usually take more than just one trip to a place. i can run round and take loads of photos with the scout lens and then go back later knowing what shots i want to do and concentrate on them.
 
I have a Sigma 18-200mm OS - it feels good and the OS works well. It's particularly great for walking around London shooting things randomly without having to change lens - you can shoot things at eye level or zoom in on architecture

f6.3 is a pain, but for the price its great
