Default Sigma 18-250mm f/3.5-5.6 DC OS HSM lens for Canon

Despite of a lot of negative reviews online and my friends' persuasions to get me not buying this lens, I forged ahead and bought one. I know its limitations not doing everything particularly well, I am willing to sacrifice some image quality for the sake of convenience for traveling.

Like I always do, I use the doll on top of my daughter's makeup cabinet as my model since no-one in the family is willing to pose for me. Here are the settings:

Camera: Canon XSi, set to Aperture Priority

Flash used: Canon 430EXII set to AUTO, bounce flash at 90 degree, no diffuser.

Shooting Range: 18mm, 24mm, 28mm, 35mm, 50mm,80mm, 135mm and 250mm taken at a distance of 5.5 feet.

ISO: 400

Aperture: f/8

Shutter: 1/200

Filter: Pro Optic 72mm MC-UV (Came with the lens)

Post processing: None except the last picture (250mm), the exposure was corrected due to a little overexposure.

G'day WCK

Looks awful mate > better sell it and retire

However, to my eyes, they all look sharp and the colour is excellent
Wanna sell it cheap??

Regards, Phil

Good choice. Vacationing with a bag full of lenses is not all that much fun.

This lens works out OK and I am pretty happy with the results so far. The built quality is good and it feels balanced on the XSi. The focusing is quiet, fast and does not hunt in low light. The only con I can think of is that it weighs almost as heavy as my 24-105mm f/4 L lens and there is a little zoom creep. The newer version of this model is smaller, lighter and has better macro, but is $120 more. Overall, this lens is a good bang for the bucks. I wouldn't say it is the best bang since I have not used the Canon 18-200mm or the Tamron 18-270mm VC PZD.

"All in ones" do tend to get a bit of flack from time to time- but I think they're a great lens given their price and the range/subjects they can cover.
Yes,they're never going to be as good optically as a bag of primes,but at standard viewing/printing sizes are MORE that adequate- and I suspect the type of individual purchasing such a lens knows and appreciated their limitations.
I owned a Tamron 18-270 VC lens- and it was great...!

I am leaving to the Silk Road tour in a couple of weeks. This is the main reason why I bought this lens. I think it will serve me well during the trip.

G'day again WCK

Good to hear that you're off 'on the old Silk Road' > never done anything like that but have heard good reports

As you will no doubt have noticed from my many postings is that I am on the road for 3/4 of every year - in my case travelling around "Oztraylia". I have limited storage & carrying space for stuff and so go for the superzoom lens so that wherever I am, I've always got the 'right' lens on

Hopefully on your travels you will find the same thing!
Regards, Phil

Thanks, Phil, Simon, Dr Spock! Super zoom lens like the Tamron 18-270mm and the Sigma 18-250mm have their place in traveling photography for those who don't want to lug heavy equipments on a long trip. I am looking forward to road test this lens in China.
