Question 1

If I have the EFS 18-55mm that came with my Rebel T1i how will I benefit from getting this lens? Is there a difference?

Accepted Answer

You will have a much better lens. The optical quality of the 50mm is much better than your kit lens. There will be next to zero geometric aberration (straight lines come out as curved with the 18-55), excellent low-light performance, and a much shallower depth of field (a much blurrier background to help your foreground stand out). Both the latter come from the faster lens - f/1.8 vs f/3.5, a full 2 stops.The only thing is that it is a fixed lens, so you cannot change your field of view. However, it's something you will get used to very soon. I started out with the 28-135mm USM, and basically stopped using it after I got the nifty fifty.

Question 2

Is this the same as the Canon EF 50mm f/1.8 II lens?

Accepted Answer

Build quality is better on the new model, and the STM focus is better for video. IQ for stills is about the same, with the new STM model having a little better color and less aberrations at wide open apertures. So if you don't have either, get the STM model. IF you have the older molder, then it is only worth the upgrade if you plan to do a lot of video.

If you would like more information about the 50mm STM model, you should check out the review I have on my profile.  It covers the pros and cons, offers advice for how to use the lens, and also has a breakdown comparison with the 50mm F1.8 II and also the F1.4 model.  There are also sample images taken with the lens (though keep in mind some are from a full frame and some are from a crop).    Here is a link to the reivew.

Question 3

Is this compatible with the canon eos rebel sl1?

Accepted Answer

Totally, your camera can fit all EF and EF-S lenses.  This is a good lens too, unmatched in sharpness and speed at its price point.  It’s ideal for portraits, and also performs well in low light.  Not wide enough to be your go to walk around lens, so hang on to your 18-55mm if you have one.  If not, I would suggest pairing this with the EF-S 24mm F2.8 STM for your wide shots, as it has a lot of the same advantages of the 50mm with a wider angle of view.  Both are about the same price, 125-150 USD.

If you would like more information about either the 50mm F1.8 or the 24mm F2.8, you should check out my reviews I have on my profile.
