How do you know if a lens will work with your camera?

best canon lens sigma image

-Mersadies

I have a Canon Rebel XT. I am in need of lenses but I'm unsure sometimes whether a lens will be compatible with it or not unless it's a Canon brand lens. The reason I ask is because I'm thinking of buying an off-brand lens (Sigma, Tamron, etc.) because they are cheaper. How do you know what will work and what won't?
I need a lens now. As much as I would love to wait and save up, I don't have time.

Answer
You are always better off buying the best glass you can. So save your money and buy Canon lenses for your Canon. After-market lens makers will specify which camera the lens fits so just buy a Canon EOS mount lens.

How does Sigma glass compare to Canon glass in general?

I've never shot with a lens that Canon didn't make, and I'm wondering if looking at other brands might be a good idea? I've heard lots of varying reports about different Sigma lenses. In your experience, how does the optical quality of a Sigma lens generally compare to that of an equivalent Canon lens?

Answer
On the lower end canon lenses it's not such a big difference. But overall, canon lenses (especially the high priced ones) are higher quality than sigma.

But the value of Sigma lenses make them great purchases. You can usually get several excellent sigma lenses for the cost of just one Canon L-series lens

What is the best reasonably priced digital camera?

best camera lens for las vegas image

Sierra Rog

I'm going to Las Vegas soon, and I'm thinking about investing in a really nice digital camera. I want one that will take really high quality and detailed pictures, but I don't want to pay $1000+ for a nice camera and all the screw on lens.
Any suggestions?

Answer
Hi Sierra,
I've had my "Sony-Cyber shot" for almost a year and I found it to take amazing pictures.
Must give it a try. I paid $150. for it, but well worth it.
Have a great time in Vegas! Don't forget to visit the Aria @ CityCenter, it's amazing.
:)

How to take pictures of Las Vegas lights at night without a tripod?

Cary M

I am not a beginner at photography but definitely a novice. I have a compact digital camera with quite a few settings options. A tripod is out of the question, so how do I get decent shots with a fast shutter speed to eliminate blur from camera shake? The camera does have image stabilization but I'm not too sure how effective it will be.

Answer
Depends on how long you want to expose for.
If you just want to get the lights and no "fancy" effects then bracing yourself against something solid and with a standard to wide angle lens then you should be able to hand hold to about 1/15 without getting movement blur.
Alternatively, prop the camera on a solid object (wall, car roof etc).
