Canon EF 12-24 f/2.8L [CR1]
« on: February 27, 2013, 08:32:35 AM »
Going wider?
We’ve spoken about the existence of an EF 14-24 f/2.8L in the past, a lens that a lot of people want to see come to fruition.

We’ve been told that an EF 12-24 f/2.8L exists in prototype form and could become a product instead of the EF 14-24 f/2.8L. I can only recall Sigma making such a lens for full frame cameras. Going this wide would certainly put some space between the cheaper (assuming based on Canon pricing history) EF 17-40 f/4L and EF 16-35 f/2.8L II.

This is the first I have heard of an EF 12-24 f/2.8L, so take it with a big grain of salt. This could be a better range in an f/4 variant, as it would be great for both full frame and APS-C and would really reduce size and weight compared to a 2.8 version.

A 12-24? I had the Tokina with that range, and it was great on crop. I can't even think how mindbogglingly useful it would be on FF.



I know this cartoon gets used for everything and its grandma, but what do you do. I'd happily shell out 2k$ for an f/4.

I dunno about you but given the loss of DOF and light gathering on a crop sensor, I prefer my lenses to be faster on them, not slower. Also the crop tends to be forgiving of fast and wide lenses' edge blur and vignetting wide open. Bring on the 2.8!

Well, I don't actually use my crop anymore, so I'd be equally happy with an f/4 - more so because there might be a chance that that actually would be priced in the 2K region. An FF 2.8 would probably be in the great white price range. But I wouldn't object to the lens per se ;)

If they can somehow make a 12-24/2.8 with the optical properties of the Nikkor 14-24, it'll be very impressive. Unfortunately the front element will no doubt make the 17 TS-E look flat.

It does sound a bit far fetched to create this with the recent optical quality of their L glass. Personally I'm not interested in something to merely equal the Sigma 12-24 optically.

Sounds very ambitious.  It would be nice if it were as sharp as the Nikon 14-24 and priced similarly, but I would very much doubt that. 

Lens design is all about compromise; I would prefer to see a 14-24 that could use the existing Lee filter system for the Nikon version, perhaps adding an internal circular polariser?

For my needs, I would prefer a lighter (and cheaper) f/4 version -maybe even starting at 16mm (I rarley go that wide) with a smaller, filter friendly front element.  To be honest, I'm probably talking about a different lens (a 17-40 replacement).

You'd need a way to get it out of the optical path, when you don't want to lose 1.5-2 stops of light.  Perhaps a drop-in type like the supertele lenses use...

--SAUCE-- lots of it too. Its cost in a 2.8 in terms of size, weight, and monies would/will be great.

I think my number one concern would be corner sharpness. Based off of recent lens releases they'll get the center nice and sharp, but especially with their super-wides Canon has had some trouble getting the corner and edge sharpness up.

As for f/2.8 vs f/4, I'd rather f/2.8 since I can stop down to f/4 or beyond to increase quality when I need, but sometimes I just plain need as much light as possible. Although it will make it cost a lot more, and undoubtedly weigh a lot more. *sigh*  Tradeoffs, it's always about tradeoffs.
