35L II with WS, and please keep the price increase reasonable. 8)

That sounds like the next offer for extended flame wars after the 5d3 :-p ... what would you consider "reasonable" for added sealing & the same iq (which can get hardly any better)?
20 - 25% seems reasonable to me.

#3 - 35mm 1.4 L - sharpness, CA (very badly needs updating, 14 year old design, Nikon's is much much better)
It is rummored to be very sharp appart from the edges/corners at f/1.4 - f/2.0 . However when someone uses such an open aperture they use it to photo people who are not at the extremes. Since I haven't this lens (but I'd love to) and I would use it for astrophotography I would like an improved 35mm f/1.4. It would cost almost the double though...

100% price increase is unreasonable.

Personally I'd like to see the 135mm f/2 L get upgraded AFTER I buy this current version. A new one will undoubtedly be out of my price range.
There would definitely be a price hike, but if/when there is a new 135 f/2 I'd expect large numbers of mint condition pre-owned copies hitting the market as upgraditis kicks in.

I agree but check the prices of the new 24mm f/2.8 and 28 f/2.8 lenses. Also compare the price of the new 24-70 f/2.8 L II and the old one. Trust me I want badly to be wrong (the more wrong the better :) assuming I err on the higher end...)

The 17-40L needs new optics (even the EF-S 15-85mm non-L lens is sharper) and image stabilization.

Why is there such a fixation for IS when on wide lens there will be very little/no benefit as motion blur will be intrusive before IS kicks in. If it is a stationary object then a monopod/tripod is the answer.

I am not convinced that the 17-40 is not sharp, especially at f/5.6 or slower

You may be correct about the 17-40L (but Canon will rather update a f2.8 ultrawide because they can get more money out of it). But "even" the ef-s lenses are very good, it's just that Canon decided for marketing's sake not to put any red rings on them or let them have better build quality.

I think Canon should look at making whatever replaces it there big UWA performer, at least beyond the TSE's that most users can afford. Rather than try to mix performance and f/2.8 together as Nikon have leave the 16-35mm as the "action UWA" where boarder performance is less of an issue and have the f/4 zoom as the sharper boarder to boarder option for the landscape market who are going to be stopping down anyway most of the time leaving a smaller cheaper lens.

It'll be interesting to see what happens should the 7D mk2 be shifted up in the market as has been rumoured. The 1D could get away with using adapted EF lenses with the more limated crop factor but I'd guess that if this camera really is aimed at the same kind of users they'd greatly welcome a 17-55mm 2.8 IS with L build quality/sealing.

IS would weigh substantially less and be significantly more compact than a monopod or tripod.

It is less sharp in the corners at 24mm than the non-L 15-85, even at f/5.6 and f/8. Given that the 17-40 is an L lens and not a superzoom, it has two reasons why it should be sharper than the 15-85.

A monopod/tripod would give much longer shutter speeds than IS

I keep hearing that the 17-40 is less sharp than the 15-85 - but on a aps-C you will find it sharper, particularly at f5.6 or slower.

Why do you keep repeating that long after I disproved it in my original post? (Hint: follow the link I provided.)

Comparing the EF-S 15-85mm with the EF 17-40mm is spurious; it only shows that the EF 17-40mm isn't optimised for a crop-frame camera. Its field of view on FF is more or less equal to the EF-S 10-22mm on a crop frame. Try TDP's comparison of these two lenses at 17mm and you'll find the 17-40mm fractionally sharper.

15-85mm on crop-frame is a simpler optical design than 17-40mm on full frame so it should be no big surprise that the 15-85mm is sharper on a crop-frame. On full frame, the 17-40mm is much better than the 15-85mm, not least because it doesn't smash the mirror to pieces. ;)

Did you try it stopped down then? I thought everyone knew that the 17-40 is soft at F/4. It is a landscape lens

I just thought I'd see what everyone wanted to see replaced most in Canon's lineup. Feel free to post your top requests for lenses that need replacement. I'll start:

Rank - Lens Name - What Needs Fixing

#1 - 50mm 1.2L - sharpness, CA (even at the the cost of aperture speed in my oppinion)
#2 - 50mm 1.4 - sharpness, Modern USM (Badly needs updating, Nikon's is far ahead)
#3 - 35mm 1.4 L - sharpness, CA (very badly needs updating, 14 year old design, Nikon's is much much better)
#4 - 135mm f/2.0 L - aperture, image stabilization (16 year old design, there are plenty of 135mm f/1.8 lenses around, would love to see f/1.8 + IS, like a mini 200mm f/2.0 IS)
#5 - 16-35mm f/2.8 II L - sharpness, CA - (it's a good lens but Nikon's 14-24mm gives it a run for it's money)

Feel free to list your own top 5

Agree with 1-4.

I think the 135f2 is an amazing lens but it really needs IS - that's all it needs IMO. I certainly wouldn't buy it for any optics upgrade.

As for 5, I'm happy with the 16-35 personally... For number 5, I'd add an 85 1.4. The 1.2 is too heavy / big / slow and the 1.8 isn't good enough for my needs. Sorry - I know it's not a replacement as such ;)

There may be some in the 200+ range that need work but I stop at 200mm personally.
