Sigma Camera Lenses For Canon
No third party lenses fit both Canon full frame cameras under small?
More specifically Sigma Tamron lenses. Are you companies make lenses for both, or do everything everything that way? So you suggest I go for 3rd party lenses at all? I've used before and no Tamron have had no problems with its quality, has no experience with Sigma however.
No, as Canon lenses, which only work with APS-C sensored cameras and other working with both full frame and APS-C Oh why, why you want to go cheap on your lenses. You will be used for decades, as you will to replace your camera body every two to three years. A used Canon will last more than a third of new lens. If you really have to buy a third party looks Tokina lens brand … are the best of them. They make lenses for Pentax digital SLR and Hoya filters.
Sigma Camera Lenses For Canon

Xsi Rebel – A Great Camera Overall
This camera is really great!
UPDATE: I’ve had mine for 3 months and I’ve taken more than 3000 pictures. I still like it a lot. Amazing.
It’s easy to use, the LCD screen is big and clear, it’s quite light, and the packaged kit lens (18-55 IS) is good. It’s not a top lens, but it delivers sharp photos across the zoom range. Default settings will give you great shots out of the box.
The 9-point auto focus is good most of times, but I found myself using the central point most often, even more so when using larger apertures (when right focusing matters most).
For under $700, this is the best DSLR you can find.
* Pros and Cons *
Pros:
– An easy to use, quick camera.
– Intuitive menus.
– 12 mega pixels.
– Great pictures, sharp, good tones.
– Small and light weight for a DSLR.
– Live view mode to almost mimic point and shoot feel-it’s slow though.
– 3.5 shots per second-could be more.
– Sharp kit lens for the price.
Cons:
– Somewhat expensive compared to the Canon 40D (much lighter though).
– ISO limited to 1600.
– Relatively low fps.
– Exposure compensation range limited.
– Does not have video.
* The competition *
The closest competitor is certainly the Canon 40D, which is a bigger, more professional camera. It has more options, higher ISO, remote flash, higher shots per second rate, fewer pixels but a definitely tougher feel.
I went for the XSi Rebel because I found the 40D too hefty.
Still, if you really want a professional camera you should look at the Canon 40D.
If you have a bigger budget, you should also look at Nikon, I really recommend the Nikon D300, it’s a really impressive camera.
* Lenses *
Canon has LOTS of lenses.
If you’re tight on budget, you should get the 50mm 1.8, a great lens for portrait. It’s a very sharp lens. You’ll enjoy the 1.8 wide aperture that allows blurred backgrounds and sharp , all of this for under $100.
It’s also a good start to get used to shoot with primes (lenses with a fixed focal length).
The 18-55mm kit lens is often paired with the Canon 55-250mm IS lens to give you an almost 14x zoom (13.9), this Canon 55-250 is a very good telephoto lens if your budget is under $300.
If you don’t want to change lenses, Canon just released the 18-200 IS and it comes highly recommended so far.
The Sigma 18-200 OS is good too. It’s cheaper and it’s been in the field for longer.

I have a SLR camera and I wanted to know who makes the better lens?
I was looking to buy some lenses for my camera and I wanted to know which brand lens I should buy. I searched for Canon, Sigma, and Quantaray. I noticed Canon lenses are a lot more expensive. Which ever one you choose, what is wrong with the other ones. i.e. if you pick Canon, then tell me what is wrong with Sigma and Quantaray.
Are Nikkor lenses better than Canon and are they only for Nikon?
I like Canon lenses. You’re paying for quality. Third party lenses (Sigma, Quantaray, Tamron, etc.) are cheaply made and don’t always offer full compatibility with your camera.
Nikkor lenses have a great reputation as well. They only fit Nikon (I’m sure someone out there has a converter but it’s not really worth it).
If you’re on a budget and truly can’t afford Canon or Nikkor, get an off brand until you can save up the $$$ for the real deal.
