Crop 50mm equivilent EF-S lens?

With the prevalence (and the improving quality) of crop bodies, how come canon haven't released an EF-S 31mm f1.8 (or even better f1.4) for use on crops as a 50mm?

I got the EF-S 15-85 bundled with the 7DII and it's a really nice lens, but I'd love a 50mm equivalent EF-S...

Hey,
Anything from 28mm - 35mm will really frame very close to a 50mm on full frame. There are a few 35mm to chose from, the 28mm f/1.8, as well.

That said, "I don't know"

Early on SIGMA released a 30mm 1.4, to much fanfare and many assumed that the OEM's would follow.

Yeah, I've had my eye on the Sigma 30 f1.4 for a while (just trying to find a way to justify it to the wife), but, after getting the EF-S 15-85 IS USM, i'm really impressed with it and can't see why Canon don't release an EF-S (lets say for simplicity) 30mm for crop body use as a '50'.

With so many crops out there, it's a no brainer that it'd fly off the shelves...

There's the Sigma 30/1.4 Art for crop bodies. There's really no difference in the couple millimeters. Even the 35mm lenses are pretty close. I love my 35/2 IS on my 7D.

Edited to say there wasn't a reply before I posted. I had forgotten about the 28mm as an option.

To put it simply, I think they'd prefer that you move on to FF.

Not sure on the 'art', I was looking at the 30 f1.4 DC HSM (older, non art model).

I get they want to sell more FF bodies, but if so, why make so many crops, especially the extremely good (basically pro grade) 7DII, and not offer a 50 equivalent EF-S lens?

Seems to me, they are missing out on a fairly simple to produce 'cash cow'...

I'd like to pose the question to the OP about what is so special with a 50mm? Is the "50mm" in your mind something referred to as the "normal" lens from full format 35mm days.

They probably sell more zooms than primes whether EF, EF-S or EF-M. Of course, if they don't offer many alternatives how could they really know? From a marketing perspective Rebel shooters can sit and spin if they don't like it (the ugly truth), 7d shooters are likely shooting long anyway, and the xxd shooters are so close to being convinced to move up to FF, there's no point in offering better EF-S alternatives.

No, it's about getting the 'human eye equivalent' perspective (so, shooting exactly what you are seeing) and, just as important, a nice wide aperture.

If I did have a FF, then my 50 f1.8 would give me this, but I have a 7DII so i'd like an EF-S lens that gives me this...

I still maintain that, if canon build it. it will sell...

The desire for a wide aperture I can understand but focal length, in itself, has nothing to do with perspective (relative sizes of objects at different distances from the camera or your eye).

First of all, your human vision is so unlike a camera that there's really no comparison. The combination of your eyes and your brain can concentrate on a very narrow field of view or take in a wide view. No single focal length can do that.

Secondly, as I mentioned above, focal length, by itself, isn't what affects perspective in our images. The distance(s) from the camera to the various elements of the scene in front of the camera are what affect perspective. Please read our "sticky" (found in the General Photography Talk forum) tutorial titled Perspective Control in Images - Focal Length or Distance?.

Ok.In that case, I want a lens that, when looked through, shows objects to be about the same distance away as they do when I lift my eye up from the camera...

How's that?

Just buy a 35 f/2 IS. Or a sigma 18-35 f/1.8 if you want options.

Both the 28/1.8 and 35/2 IS are both pretty fast in aperture and both reasonably priced for 50mm equivalent options. I think the bigger question is why there is no 35mm fast equivalent option. The EFm series got the 22/2 as the first one or two options. However in EFs land, you fork over $1600 for the L or you buy the slow 2.8 IS prime.

somewhere in your 15-85mm, that lens hides. Your mission (should you choose to accept it) is to find it!

The wife will NOT sign off on a $1500 35L...

I'd be happy with an EF-S 30mm f1.4 (at a reasonable price), and i'm sure many thousands of other canon crop owners would be too...COME ON Canon...

yeah, but at f3.5 or 4...
