I just bought my first SLR Camera. I bought a Canon Rebel XSi ESO450. (I think). I didn't get the lens that came with the kit. Ididn't like the idea of changing lens all the time....maybe I justdon't know what the "norm" is. But, I want to buy a good aroundlens.
Ihave a camera now that has a great zoom (X10) so I'm use to zoomingout a lot. Would I want to buy a Tamron Di II Af 18-250 F/3.5-6.3or a Canon Ef-S 17-85 1:4-5.6 IS ? I have no idea if either will fitmy camera. I need all the help I can get. Thanks, Lady Bug.
You bought a camera body costing about 500 without a lens because you don't know what sort of lens you want... well, I wouldn't do it that way....
If you don't like the idea of changing lenses and want a good all-in-one, general-purpose long range zoom the Tamron 18-250 is a very good choice. Yes, it comes in a Canon fit - you have to specify that when you buy it..
Thanks, I appreciate you answering my question. Lady bug..
Lenses for SLRs tend not to be quite as good when they have a very wide zoom range..
So one with a shorter range, like 1785 will usually take better photos than, say, an 18250 lens. But you might feel the compromise is worth it..
A good all-round shorter zoom is the Sigma 1770, which has a handy 'macro' ability (not true macro but you can focus very close)..
Sigma make an 18200 zoom with 'OS', which is an image stabiliser. I think this is an important feature on a long zoom. 18200 is equivalent to 29320mm on the camera you've bought (look up 'crop factor' if you don't know why this is), so you'll need to be steady handed or have a stabiliser (or preferably both) when zoomed to the telephoto end of the zoom..
The Canon lens you mentioned is good too, and to be honest, the kit lens would also have been a good starter lens..
Again, if you buy a non-Canon brand lens, make sure you buy the Canon version..

Please remember that any lens represents a set of commercial compromises, and some of the things that are compromised in the wide range do-it-all zooms are....
Size. It'll be relatively big and heavy, and not great to carry around or hold up for pictures, especially those with upright framing. Indeed, you may find it hard to use without a tripod..
Image quality. Whilst the sharpness could be adequate around the middle of the range, it may not be great at the ends. There is also likely to be some distortion at full wide and tele f-lengths, which will show up when straight lines are near the edges of shots (buildings)..
Low light performance not good. Because of their considerable f-length range these lenses tend not to have wide maximum apertures. This can be a big problem in low light, or with action shooting. The problems are worse the longer the tele setting you try to use..
Would I buy a lens like that?.
Well, no. I wouldn't..
I would split the range of f-lengths I required across a minimum of two separate zoom lenses, and put up with the hassles of swapping lenses when needed. However, I would put my NEXT money down on a second camera body, not a third lens.Regards,Baz..
I recently went to the PMA Convention and had the opportunity to have a play with the Tamron 18-250 on a 400D - I was *stunned* at how small it was. I too thought that a zoom with that focal range would be pretty cumbersome but it wasn't at all. I had a woman breathing down my neck waiting to have a turn so I didn't get too much time to really test it but it exceeded my expectations in the time I did have with it. I only headed over to look at it as I had asked a pro photographer who had been doing a series of lectures which lens he would choose if he went travelling and had to choose one lens (trite question, I know) - he told me the Tamron hands down..
Good luck with your lens choice - don't make a choice lightly, research as much as you can and think about what's important to you. Barrie was dead right in the things he gave you to think about earlier and you really do need to think about what is right for you..

Thank you for your acknowledgement..
In my turn I am happy to acknowledge that I haven't handled the Tamron lens you mentioned. It sounds like quite an exception to ALL the usual rules, so I will keep my eyes and ears open....
.... just in case I need to modify the opinions I express..
Thanks again for your up to date information.Regards,Baz..
You can find a review of the Tamron 18-250 (for Canon mount) here:.
(this is a good site with a lot of useful lens reviews on it)..
They are quite impressed with this lens:.
'The results may not touch the sky but the new AF 18-250mm delivers a very solid performance for most of the range. Unsurprisingly the weak spot is at 250mm @ f/6.3 - stopping down to f/8 is a good idea here. Nonetheless the resolution characteristic is fairly amazing regarding the extreme zoom range.'.
'All-in-all the Tamron is a decent allround/travel zoom lens. Just be a bit careful regarding it's rather slow max. aperture at the long end. Unless you've a DSLR with built-in image stabilizer (Sony, Pentax) you'll often find yourself choosing ISO 400 although this isn't really a problem with the low-noise Canon DSLRs so far.'.

Be sure to click through the links provided at the end of each article. For instance, at the bottom of the "Prime vs Zoom Lenses - Which are Best?" page, there are links at the bottom to topics such as "Prime Lenses - an Introduction" and "DSLR Lenses - An Introduction.".
The site link was posted earlier in this forum by natureman, and it has lots of great information for beginners...
The Tamron does seem to be a nice lens but the image stablilzation in the Sigma would have swayed me to it. Not that I have the choice of using a Tamron with my Sigma DSLR, but the 18-200mm DC OS lens is quite a value. The fact that these super zooms are not the greatest low-light capable lenses adds to the benefit of having one with image stablization.My humble photo gallery: http://ntotrr.smugmug.com.
