Is there an EF or EF-S equivalent to a Normal 50mm prime for 1.6x bodies?

A 50mm lens on a 1.6x body ends up being 80mm. But, is there a prime lens for the 1.6x bodies that ends up being 50mm once the crop factor is taken into account?

Thanks in advance

Try focal length divided by the crop factor - ie 50/1.6 = 31.25. So 30mm should see the same, if not similar results.

the closest are sigma 30 1.4 or canon 28mm.

Exactly what I needed to know. Thanks for the info!

Generally, people use the 28mm f/1.8 or 35mm f/2 for a roughly 50mm equivalent on a 1.6x cropper. If you're willing to go outside of Canon, the sigma 30mm seems to be a fine lens WHEN it is working properly (meaning: it may have to be returned for another or sent back to Sigma for calibration.) Of course there's the 35L as well .

Though most of us who have been around on the forum for a while fully understand the quote above, the newbies who read this may not be so insightful.

For the newbies - it is important to understand that no lens' focal length (or the aperture values, for that matter) changes at all just because it is fastened to different format cameras ("format" refers to the size of the film frame or digital sensor in a camera). A 50mm lens is always a 50mm lens.

What FlipsidE should have said instead of the highlighted line in the quote above is something like: A 50mm lens, used on a 1.6x (or APS-C) body, provides the same field (angle) of view as an 80mm lens used on a 35mm film camera (or a so-called "full-frame" DSLR).

The question has been answered pretty well above. Something around 30mm used on an APS-C camera will emulate the 50mm focal length used on a 35mm film camera.

Canon 28/1.8
Sigma 30/1.4
Canon 35/2.0
Canon 35/1.4 L

So am I getting this right????

A 30mm lens on a 1.6x crop D-SLR will give me (roughly) the same photo as a 50mm lens on a full fram D-SLR......

I'm guessing I can expect to see the same angle of view, so what fits in the photo on one setup should be pretty close to what fits in the photo from the second setup....

Could anything else be different, bear in mind I have no idea what I'm talkign about.

Yah, you got it - 48mm tho ...

depth of field, perhaps . . . though i don't have much more idea than you

You got it right.

As said above, there will be a slight difference between the two combinations relative to depth of field, but the difference - for all practical purposes - is rather negligible.

Sigma 30mm f/1.4 is the best alternative : fast "usm", f/1.4, same focal (50mm/1.6 = 31.25mm)... This lens had very good reviews. But it's only available for APS-C sensor.

Recently bought a Canon EF 28 f/1.8 for this very reason. It's equivalent to 44.8mm on a full frame sensor.

Also, although 30mm isn't especially "wide" - you could potentially see some additional distortion if you get too close to your subject - that you may not see with an actual 50mm

i got a 2nd hand hardly used Sigma 28 1.8 and love it
