New f/4L EF Zoom [CR1]
« on: July 20, 2010, 09:35:04 PM »

New Lens with the 24-70 IS?

This is the 3rd or 4th time I’ve been told about the possibility of this lens.


An EF 16-50 f/4L H-IS


Would it replace a 17-40? or be added to the lineup?


If this was sharp at the corners on full frame, would anyone ever buy a 17-40 or 16-35 II again?


With such high ISO performance now and obviously improving in the future, is a wideangle zoom at f/2.8 have much of a point anymore?


Nikon has brought about the 16-35 f/4 VR to mixed reviews, a Canon counterpart makes some sense.


Grain of salt on this one, the lens would sell exceptionally well however.


Rumor Reminder

There have been instances when CR1 rumors have become real products, a lot of truths start from stuff like this.


Also keep in mind Canon has not been busy with announcements in the last year. There were no lenses announced with the 1D Mark IV (70-200 was at a different time) and T2i.


We haven’t seen much in the way of lenses since the 7D.


Big things coming.

The 17-40 and 16-35 are very different lenses aimed at different uses. The price differential creates a further dichotomy among users.

An f/4 wide angle to mid tele like the rumored 16-50 with IS would be supremely useful as a wide angle walkaround. And great for landscapes and close-ups in lower light thanks to its IS.

Canon would be wise to release a 14-24 f/2.8 at the same time, the true successor to the 16-35 II.

In this way Canon would distinguish these two lenses more significantly. Many people would want to own both.

I certainly don't think the high ISO ranges of newer cameras negates the need for f/2.8 zooms.  Some will always have a preference for the depth of field of an f/2.8 and f/2.8 will always allow you to use a lower ISO and higher shutter speeds relative to f/4.0, which will still allow for incremental improvement in some situations.

That being said, the performance of the 16-35 f/2.8 II leaves something to be desired.

I'm quite happy w/ my 16-35 f2.8 II on FF and APS-C. Would not want to trade it for a 14-50 f4  ;)

If this was a CR+3 my 17-40 would be on ebay right now.

I would be a bit worried about the size of this new 16-50L IS.

I think the most notable advantage of the 17-40 is its compact size. However, if the evolution would involve a change similar to 16-35L I to 16-35 LII... (and don't forget how IS tends to make the lens bigger)  :-\

With a new 24-70LHIS coming, I'm more interested in a 12/14-24, & since I already have the 16-35II...
It would have to be flawless at this point to get my $.

From the specs of this rumored lens, I'd say it might end up being EF-S, not EF. Effectively for APS-C what the 24-105 is for FF.
If it was sharp it might replace my EF-S 17-55 2.8 IS, which seems to be quite a lemon (corners don't sharpen up enough even at f5.6), but it would never replace my 24-105, a FL range which I actually prefer over the 17-55.
If they made it 16-70 f4 (and if Canon would stop being greedy with their current pricing policy), I would definitely get one.

if this is EF ... at first glance my jaw almost dropped since i just bought a 17-40L for FF and a 17-50 2.8 VC for crop ... this could have been the one lens solution to both the lenses above.

but realizing that while it has IS, 2.8 is still 2.8.  2.8VC at that.

i will rest easy now unless this was price around 1k or lower.  (nikon is 1200)

I would appreciate such a zoom, but why start at 16 and not 15?. Then you will have a 24-80 on a APS-C.

A tad more WA would of course be nice, but if it comes with the quite massive distortion of the 15-85... of course DPP can correct this, but after correction, the effective focal length/viewing angle will be smaller due to the cropping involved in distortion correction. So we probably wouldn't gain too much for all applications were distortions are not acceptable. Add in that this correction also tends to loose resolution in perhaps already not that great corners, and I think we can do without 15mm.

H-IS on such wide lens makes a lot of sense indeed.  Typical CR rumour - half made-up, half fantasy.

Canon is really short of new lenses.
- 14-24 f/2.8 (or better still, 14-24 f/4L with front threading)
- 24-70 f/2.8 IS
- 35 f/2 micro-USM
- 50 f/1.4 micro-USM

and cameras:
- D90 direct competitor
- EVIL camera

And MOST importantly, Canon needs to improve on their QC and sensors. They should even try to dabble with in-camera RAW NR like Nikon, Sony, Pentax, Olympus etc.

Only then can they regain their reputation and market share.

If it's real and it's good, i would change my 17-40 immediatly for a 16-50 L IS (even not Hybrid).
It would also be the first time that Canon produce an L lens thinking (at least a bit) at the APS-C format (25,6-80 mm), this would be a great news to me in general.

I agree with Woody in many points but: - new lenses should loose the micro-USM, the new 50 1.4 it's rumored to be USM ring.
Quote for QC and sensors.

Ooops... I meant ring USM, NOT micro USM.  :-[
