Aloha,

I just got my Rebel XT and have been cruising these forums for some advice on upgrading the "kit lens" that came with the camera. I prefer to get one"walk around" lens instead of a two lens kit. I was looking around and found this lens:

Canon EF 28-105mm 1:3.5-4.5 USM

Seems to be very popular and rather inexpensive ($250ish). Would this be a decent upgrade from the kit lens? My needs are most "family" stuff with soccer, trips, birthdays, etc. The kit lens doee not seem to have enough "zoom" for me. I had a point and shoot Lumix w/12x zoom which I enjoyed. I know that this will not zoom in as far but this seems to be a good balance between optical quality and zoom. Any other sugestions? I've seen some Sigma and Tamron lenses but am not sure of the optic quality.

One of the 18-200s would probably best suit your needs. Canon's cheaper lenses are not very good value as many third parties have newer and better models and these are generally also cheaper.
I have to ask though, if you only want to have one lens why did you buy an SLR?

Could you be specific as to what 18-200 lens you are referring to?

Also, as stated, I am new to DSLR. I can always get into buying more lenses later. For now, I would like to have one decent lens that I can get more familiar with the camera.

The Canon 17-85 IS lens is an excellent upgrade. After the conversion factor of 1.6x, it is the equivalent of a 27-136 mm lens on a35 mm. camera. It is worth the price. You can sell your old lens on e-bay.

My friend, you bought the wrong camera. The lens you want is a Nikon 18-200mm VR. Problem with a 28-anything lens as an all-purpose lens is that it is not wide enough on your camera. That is why the kit is 18-55, and the popular upgrade is 17-85mm. I have the 17-85mm, and it is fine. Too short for soccer, though. That's where the 18-200 would be handy. Tamron and Sigma both make an 18-200mm lens in a Canon mount, but neither have image stabilization like the Nikon. The Canon 17-85 has IS, but it is not long enough.

Oh yes, the other advantage of the Canon 17-85 is that it will get you lots of practice in fixing chromatic aberration in Photoshop! What a pain that lens is shooting high contrast--mountains, buildings, etc.!!!

Tamron 18-200mm f/3.5-6.3 XR Di II AF

Sigma 18-200mm f/3.5-6.3 DC

Nikon 18-200mm f/3.5-5.6G IF-ED AF-S DX VR

Looks like I have narrowed it down to these three although the Nikon may be out of reach ($750). So really between the Sigma and Tamron. If its a toss-up, the Sigma is a little cheaper.

What you need is DXO Optics, it's a software upgrade for all your lenses - you won't need an L!

Seriously though, even without DXO I have never had a shot with significant CA from my 17-85, vignetting and distortion yes, but CA no. Perhaps there is lens-to-lens variation? A problem with the coating on some of your elements during manufacture perhaps.

Of course, it is not a toss-up--at least as far as the Nikon lens goes. You can't use the Nikon lens with your Canon camera.

Do a search and find test results on the Tamron and Sigma. I have a few Sigma lenses: 50-500 (aka Bigma), 70-300 APO, and 12-24 (aka Popeye). In my experience Sigma customer service has been excellent--far better than Canon's. My only Tamron is a 1.4x extender. It's OK, but is really a relabeled Kenko. A friend of mine uses the 18-200 Tamron and likes it just fine.

I'll look into DXO. Seems like I read about that once before, and it was a fairly expensive program, although as you point out, a lot cheaper than new lenses.

My 17-85 seems consistent with the reviews and reports I've read. Users scream about the CA. The barrel and pincusion distortion is a bit of a throwback to the early days of zooms. I have not experienced the vignetting, though, even with a polarizer. I've read about sample variation in Canon lenses, but I've yet to find definitive proof--only claims on various forums ("I had to send back thennn lens three times before I got a good one").
